110-875: The San Francisco Police Department ( SFPD ) is the municipal law enforcement agency of the City and County of San Francisco , as well as the San Francisco International Airport in San Mateo County . In 2000, the SFPD was the 11th largest police department in the United States . The SFPD (along with the San Francisco Fire Department and the San Francisco Sheriff's Department ) serves an estimated population of 1.2 million, including

220-473: A Walgreens pharmacy in Civic Center was "ransacked" for a lengthy period of time by at least seven people in front of a KPIX-TV television producer and other "stunned" bystanders. SFPD officers did not respond to the scene until four hours later, by which time the store had closed and no one was present to make a report about the incident. The San Francisco Police Department is led by a Chief of Police who

330-583: A "half-cock" notch safety but the design was revised in 1983 due to numerous inadvertent discharges. The M1 Garand created a safety with a metal rocking lever at the front of the trigger guard that is now called the Garand-style safety , used in the Ruger Mini-14 rifle and Marlin Camp carbine . Some bolt-action rifle safeties have three positions: "fire" which allows the gun to fire, "safe" which does not allow

440-449: A "top notch" task force, called CR ime U nit to S top H omicide, to solve and suppress the murders and investigate violent illegal narcotics cell groups and other violent crimes. Inspector Bob McMillan, Officer Nash Balinton and his partner Officer Paul Lozada, Officer Mike Bolte, Officer Michael Philpott, and Sergeants John Monroe, Maurice Edwards and Kervin Silas, were personally selected to

550-474: A Western Addition housing project. The SWAT team also executes high-risk warrants in the City and County of San Francisco. They are also one of the oldest serving agencies doing city crime suppression (the act of saturating high-crime areas with large numbers of officers and police presence—a more proactive approach) along with LAPD SWAT and NYPD Emergency Service Units . The San Francisco Housing Authority Police

660-454: A button under the slide, whereupon tension from the striker spring would push it back to the engaged position. Thus, engaging the safety also relieved some tension in the striker spring. As the Ortgies is a pocket pistol meant for personal defense, this feature eliminates the problem of failing to disengage the safety when one needs to shoot. Gripping the pistol tightly is all it takes to disengage

770-472: A chambered cartridge. A second purpose is to allow the sear to "catch" a hammer that is falling when the trigger has not been pulled, such as in cases where a drop jarred the sear loose or when the hammer was not fully cocked before being released. However, a safety notch used to "half-cock" a firearm is an active feature that must be engaged, and does not positively prevent accidental discharges in all cases. A certain amount of manual dexterity and familiarity with

880-547: A character apparently modeled on SFPD's real-life chief at that time, Thomas J. Cahill , to whom the book is dedicated. More recently, Collin Wilcox wrote a long series featuring Lieutenant Frank Hastings of SFPD's Homicide Detail. Laurie R. King won an Edgar for her first novel, A Grave Talent (1993), which introduced Homicide Inspector Kate Martinelli, who has gone on to headline such books as With Child (1997), an Edgar nominee, and The Art of Detection (2006), winner of

990-400: A company, with a complement of 40 Reserve Officers divided into three squads, each with a designated squad sergeant. For special events like New Year's Eve, Halloween night, and other citywide events, Reserves are assigned as a squad. Before Reserve candidates are considered, they must meet the same eligibility criteria as a Q-2 Police Officer Recruit. Furthermore, each candidate must completed

1100-403: A decocker, manual safety, or both. However, the exact configuration depends on handgun type, year, make, and model. Double-action only (DAO) pistols, which usually use designs similar to traditional double-action but without the ability to remain cocked, do not usually have external safeties. Most single-action revolvers have no external safeties. The original designs, which dated to back before

1210-497: A discharge, with internal safeties preventing non-trigger-pull discharges (e.g., dropping the gun). Almost all modern semi-automatic handguns, except some exact replicas of antique models, have some form of safety mechanism including a "drop safety" that requires a trigger pull to discharge a cartridge. Single-action designs such as the Colt 1911 virtually always incorporate a manual safety, while traditional double-action pistols incorporate

1320-463: A feature, and as a result if the trigger was held the newly chambered round would be fired as soon as the breech had been closed. Such disconnects or interlocks are generally simple to incorporate, and in fact are a by-product of many firearms' actions; pulling the trigger while the breech is unlocked or open does nothing as the mechanism is not fully reset until cycling is complete. As such these features are often not considered "true" safeties, although

1430-458: A firearm is also required to "half-cock" a firearm; unfamiliarity with how to engage the "half-cock" position can result in accidental discharges. Moreover, safety notch and "half-cock" style safeties are prone to breakage which can result in unintentional discharges leading to severe personal injuries or death. A firing pin block is a mechanical block used in semi-automatic firearms and some revolvers that, when at rest, obstructs forward travel of

1540-401: A firearm. Manual safeties are as varied as the designs of firearms themselves, but the two most common mechanisms are a block or latch that prevents the trigger and/or firing mechanism from moving, and a device that disconnects the trigger from the firing mechanism of the firearm. Other designs may block the hammer or striker from forward movement or act as a block to prevent them from contacting

1650-487: A full-time Police Officer and serve at the pleasure of the Chief of Police. San Francisco has been known for their elite SWAT team, composed of volunteer and selected officers from the entire agency. Most training is done in-house, with occasional and required training by FBI instructors, other Federal Agencies and private Military instruction. The SWAT division participates in planned and coordinated raids with agencies such as

1760-406: A hammer follows the bolt carrier group forward as it closes. Examples of the variety of typical semi-auto mechanisms are a stiff double-action trigger pull with the safety off ( Beretta 92F/FS ), a double-action with no external safety ( SIG Sauer P-series , or Kel-Tec P-32 ), or a crisp single-action trigger pull with a manual safety engaged ( M1911 , FN Five-seven and certain configurations of

1870-413: A hammer, so the only way to return the trigger to its longer pull (safer) state is by means of a decocking or detensioning lever which actually releases the tension in the striker's spring without allowing firing pin full travel and internal safeties disengagement (such as the firing pin block which these types of firearms are generally fitted with). When a handgun is fitted with a "decocking" lever, there

1980-476: A handful of missions in the video game Call of Duty: Advanced Warfare , most notably they assist the military in stopping a van carrying drones to destroy the Golden Gate Bridge . Unfortunately they fail, resulting in the destruction of the bridge, pinning down an aircraft carrier. The main protagonist saves one SFPD sergeant from plunging to his death from the wreckage of the bridge. Most main protagonists of

2090-470: A loaded chamber indicator is an empty chamber flag . A trigger disconnector captures the hammer in the cocked position after a shot has been fired, even if the trigger is held to the rear as the gun cycles. This ensures the gun can only fire in the semi-automatic mode, as the trigger needs to be released to 'reset' and have the disconnector release the hammer back to the trigger sear. It also prevents out-of-battery " slamfire " malfunctions that occur when

2200-485: A loaded chamber under the hammer. Some single-action revolvers have relief cuts in between cylinder bores that allow the hammer to be rested directly upon the cylinder with no chance of interacting with loaded cartridges or primers. These are also known colloquially as "safety notches." They are usually found on black-powder revolvers, but there are also metallic cartridge-firing revolvers with safety notches. Most double-action revolvers have no external safety devices;

2310-517: A magazine disconnect, as a backup gun for law enforcement officers. "The absence of a magazine disconnect safety also is a benefit for tactical reloads that allow the user to engage a target with one round remaining in the chamber and the magazine out of the gun for reloading," Ruger said. A tactical reload is the tactic of replacing a partially empty magazine with a fully loaded magazine in a situation where increased capacity might be needed. These safeties, similar to grip safeties, are de-activated as

2420-669: A manual safety in its function, but is momentary; the safety is deactivated only while the shooter maintains their hold on the grip, and is reactivated immediately once the shooter releases it. The M1911 design is a popular example of a handgun with a grip safety, while the Uzi submachine gun and the HS2000 (marketed in the US as the Springfield Armory XD ) and its descendants are other notable examples of this type of safety. A related grip-type safety

2530-493: A mechanism that engages an internal safety such as a firing-pin block or trigger disconnect. An early example of its use was in the Browning Hi-Power pistol. As with any firearm feature, there is debate regarding the necessity of a magazine disconnect. Historically, most magazine-fed firearm designs had no magazine disconnector. There are exceptions, notably Ruger rimfire rifles and some of their newer handgun designs, and

2640-676: A minimum of 24 volunteer hours per month to retain peace officers status, although there are Reserve Officers who routinely contribute two to three times that number. Reserve Officers are involved in many areas of police work. Although most reserve officers actively participate in patrol, others work for such details as Muni, the Fugitive Recovery Enforcement Team, Vice, juvenile, emergency operations, DUI check-points, transporting prisoners, Command Van duty, and fixed posts at special events like 49er Football games and Sigmund Stern Grove performances. Reserves are now organized like

2750-520: A murder investigation as the United Nations is meeting for the first time in San Francisco, finds himself pitted against an NKVD assassin. White Rabbit by David Daniels, set during 1967's Summer of Love , follows Homicide Inspector John Sparrow as he pursues a serial killer stalking the residents of San Francisco's Haight-Ashbury neighborhood. A future version of the SFPD play a minor role in

2860-436: A natural consequence of the shooter firing the firearm, but are engaged in most other circumstances. The trigger is composed of two interdependent parts, and the shooter in firing the firearm manipulates both parts of the trigger. Conversely, unintentional pressure or a strike against the trigger is unlikely to do so, and such an action will not fire the firearm. Such a design, made popular by Glock pistols but originally used in

2970-405: A silver star badge. Inspectors were initially the equivalent of a lieutenant rank and pay, but are now equivalent to a sergeant rank and pay. Tenured officers will have blue and gold hash-marks on the lower left sleeve of their Class A, B, and C (BDU) long-sleeved shirts. Each mark represents five years of service. SFPD members are also eligible for bronze, silver, and gold Medals of Valor. Annually

3080-512: A single-action decocker was the Vis wz. 35 "Radom" redesign in 1932 to enable horsemen to safely holster their firearm with one hand. The earliest use of a cocking/decocking lever is the Sauer 38H from 1938. Ruger until 2007 manufactured "decock-only" variants of its P-series pistols, and the "two-way" decocking safety has been available on these pistols since their introduction. Many jurisdictions such as

3190-544: A sniper on a rooftop before a murder was committed. The unit was reactivated in the late 1990s, but after another fatal crash (which killed two SFPD officers, Kirk Bradley Brookbush and James Francis Dougherty) the Aero unit was put into an "inactive" status indefinitely. In times where it needs air support, the SFPD contacts the California Highway Patrol who have a Napa air base. The original San Francisco Police Academy

3300-404: A spring-loaded pad that forms the upper portion of the trigger face and manipulates a similar lock. This design has more moving parts, but is advantageous in that accidental pressure on the lock release has reduced leverage thus requiring more force to pull the main trigger, where force against the lower portion does not release the lock and will not move the trigger. The loaded chamber indicator

3410-430: A sticker reading "EMERGENCY DIAL 911". The SFPD has supplemental levels for ranks up to captain, depending on P.O.S.T. certification. Example; Q-2, Q-3 or Q-4 Police Officer for Basic, Intermediate and Advanced Peace Officer Standards and Training (P.O.S.T.) certification. Inspectors do not use chevrons to identify their rank—instead they wear a gold star badge similar to lieutenants and above. Sergeants and officers wear

3520-595: A sufficiently firm trigger pull will always result in firing. The heavy trigger pull required to cock and then fire the firearm usually prevents accidental discharges due to dropping or mishandling the gun. Most modern double-action revolvers have an internal safety, either a hammer block or a transfer bar, that positively prevents firing without the trigger being pulled. The only modern double-action revolvers with external safeties are unusual cases available only on special order or modified through aftermarket conversions. Pistols made and imported by Glock Ges.m.b.H. , such as

3630-735: A trilogy of police novels set in other parts of the Bay Area, retired San Jose Police Chief Joseph D. McNamara wrote one novel, Code 211 Blue (1996), about a narcotics inspector who uncovers corruption within the SFPD. Another former cop, Robin Burcell, who spent twenty years in law enforcement, first as an officer in the Lodi Police, then later as a criminal investigator for the Sacramento County District Attorney's Office , wrote four novels featuring Homicide Inspector Kate Gillespie,

3740-407: A unique key before the gun can be fired. These integral locking mechanisms are intended as child-safety devices during unattended storage of the firearm—not as safety mechanisms while carrying. Other devices in this category are trigger locks , bore locks, and gun safes. The most common form of safety mechanism is a switch, button or lever that, when set to the "safe" position, prevents the firing of

3850-454: Is a device present on many semi-automatic handguns intended to alert an operator that there is a round in the chamber. It is typically a small button or pivoting lever (though sometimes a rod, such as on the Ruger series of .22 LR handguns, which are not slide pistols), generally located just behind the ejection port on the slide of the handgun that pops up to indicate the presence of a round in

3960-451: Is also printed on the trunk, either near the center of the decklid (on sedans) or near the right taillight (on SUVs). The car's 'shop number' (used to identify all vehicles operated by the city) is printed on the front doors below the A-pillars, on the trunk near the left rear taillight, and on the roof to help air units visually identify cars. On the rear side panels on both sides of the car is

4070-421: Is also used for vehicle training exercises and mock police car chases , and Lake Merced is the location of the academy's firing range. With a boom in retirees in the coming years, a projected 700+ officers will be hired within the next five to ten years, meaning full academy classes for some time. Lateral officers are currently being hired, and are being hired on an ongoing basis. For 56 years, SFPD headquarters

4180-666: Is appointed by the Mayor of San Francisco. The chief works with two assistant chiefs and five deputy chiefs directing the six bureaus: Administration, Airport, Chief of Staff, Field Operations, Professional Standards and Principled Policing and Special Operations, as well as the Municipal Transportation Authority, and the Public Utilities Commission. There are commanders appointed to assist the Deputy Chief with

4290-581: Is composed of Harley-Davidson Road King motorcycles. There is a separate division called Honda Unit, that is composed of Suzuki DR-Z400 S dual-sport motorcycles (which is under the command of the Special Operations Bureau and not the same as Traffic), for city patrol and patrol in and around the area of Golden Gate Park . Otherwise, every one of the 10 main police stations in the city have 2 motorcycles under their command, used for patrol around their districts exclusively. The SFPD "Aero" Squadron

4400-400: Is moved into place by the normal action of the trigger, providing similar "drop safety" to a firing pin block. Popular on bolt, pump and lever-action firearms such as shotguns and rifles, a bolt interlock disengages or blocks the trigger if, for any reason, the bolt/breech is not in its fully closed, ready position. A variation is the trigger disconnect which prevents the gun from firing until

4510-410: Is no need to pull the trigger while holding the lever like in a revolver. The actual process of "decocking" the gun is done by simply flipping the decocking lever to its "decocked" position with the fingers away from the trigger. A decocker or manual decocking lever allows the hammer to be dropped on a live cartridge without risk of discharging it, usually by blocking the hammer or retracting or covering

4620-403: Is that determining whether the gun is safe becomes linked to the presence of the magazine as opposed to actually checking the gun, opening the action, and making sure it is unloaded." Another concern is that if fatigue, debris or rust cause the disconnect mechanism to fail, it will most likely do so in the "fire" condition. Further arguments are that functionally without a magazine the firearm

4730-488: Is the decocking grip found on some H&K pistols like the P7 Series . The firearm is cocked and ready to fire only when the front of the grip is squeezed by the operator. When the grip is released, the firearm is decocked, and the single-action trigger will not cock the firearm, therefore it will not fire unless the grip is squeezed and the trigger pulled. Alternatively, the trigger can first be pulled and then it will fire when

4840-452: Is the only fully functional department that utilizes the entire traffic fleet for escorts in the nation. No other metropolitan city utilizes all its motor bikes for escorts but SFPD. The entire 43-man unit is based at the Hall of Justice at 850 Bryant Street. Unlike most cities, they patrol as solo officers (hence the name SOLOS). They can frequently be seen throughout the city. The bulk of the unit

4950-572: Is the smallest administrative subdivision . They receive funding from the city budget, and may have fewer legal powers than the "state paid" police. These police forces usually report to a mayor or a local police board. Historically, the role of the municipal police of local civic protection was carried out by watchmen . Today, some formations of municipal police still carry the name of the city/communal/municipal guard. Decocker Safeties can generally be divided into subtypes such as internal safeties (which typically do not receive input from

5060-528: Is useless except as a club. Without the disconnect feature, a gun owner or police officer who accidentally releases the magazine in a gunfight would still be able to fire the bullet in the chamber; if a magazine was lost or otherwise not available, then at least the gun could be chambered with a single round to be used as a single-shot firearm. A Pro variant of the Ruger LC9s was introduced in December 2014, without

As of 2007, it is mandatory that SWAT team members are together, sometimes during routine patrol, and can be seen among the streets of San Francisco in BDU and traveling in a marked SUV, to ensure a quick and timely response to calls. They were under political fire in the highly publicized 1998 Western Addition Raid, in which more than 90 SFPD SWAT and Federal Agents raided

Like most police agencies throughout California, SFPD patrol units are painted in black clearcoat with the roof, doors, and pillars painted white from the factory. The front doors of their motor vehicles bear a blue seven-pointed star with the letters "S.F.P.D." printed in gold. This decal

5390-456: The Glock 17 , incorporate a design with three levels of integrated safety, known as safe action ; there are no external safety switches on these handguns. First, an integrated trigger latch prevents the trigger body from moving unless the trigger is positively squeezed. Second, the gun's striker-firing mechanism is locked in place by an extension bar linked to the trigger; the striker cannot move unless

5500-501: The HK USP ). An alternative are striker-fired or " safe action " type firearms which have a consistent trigger pull requiring force greater than required by a single-action design, but lighter than needed for a double-action trigger. Many such firearms do not have an external safety or external hammer ( Glock pistols and the Walther P99 and variants). In both cases a trigger pull always sends

5610-511: The Lambda Award for Best Lesbian Mystery Novel. James Patterson 's novels about Homicide Inspector Lindsay Boxer , introduced in 1st to Die (2001), have become best-sellers, and were the basis for the short-lived TV series Women's Murder Club . Former SFPD detective and current Bay Area private investigator Jerry Kenneally has written two novels featuring Homicide Inspector Jack Kordic, The Conductor (1996) and The Hunted (1999). After

Mayor Alioto immediately declared a state of emergency, assumed legislative powers, and granted the strikers' demands. City Supervisors and residents sued but the court found that a contract obtained through an illegal strike is still legally enforceable. In 1997, the San Francisco International Airport Police merged with SFPD, becoming

5830-443: The firing pin before releasing the sear . This eliminates the need to pull the trigger or to control the fall of the hammer; however, since all mechanisms can fail, it is still necessary to keep the muzzle of the gun pointed in a safe direction while decocking. A decock/safety is a combination manual safety switch and decocking lever. Two popular variants exist. In the "three-way" system, made popular by Heckler & Koch pistols,

5940-445: The firing pin , but is linked to the trigger mechanism and clears the obstruction to the pin just before the hammer or striker is released. This prevents the firing pin from striking a chambered cartridge unless the trigger is pulled, even if the hammer is released due to a faulty sear or the gun is dropped or struck by another object. A hammer block is similar to a firing pin block. It is a latch, block or other obstruction built into

6050-582: The iOS novel Cause of Death are officers of the SFPD. In fact, a main protagonist of the game (Malachi "Mal" Fallon) has his name taken from that of Malachi Fallon of the real SFPD. The SFPD has been fictionalized in the 2004 video game Grand Theft Auto: San Andreas as the San Fierro Police Department and in the 2014 animated film Big Hero 6 as the San Fransokyo Police Department. The SFPD were fictionalized in 2016 when

6160-440: The 1897 Iver Johnson Second Model Safety Hammerless revolver , incorporates a trigger with a spring-loaded lever in its lower half. This lever which protrudes from the trigger face must be fully depressed in order to disengage a lock that allows the main trigger body to move. Unintentional pressure against the top of the trigger without pressing the lever does not disengage the lock and the trigger will not move. Other designs include

6270-526: The Bean , The Laughing Policeman , Bullitt , the Dirty Harry film series , 48 Hrs. , A View to a Kill , Metro , Rush Hour , and Zodiac , as well as television series such as The Lineup (aka San Francisco Beat ), Ironside , The Streets of San Francisco , McMillan & Wife , Nash Bridges , The Division , Killer Instinct , The Evidence , Charmed (1998–2006), Murder in

6380-606: The Best of Their Ability . The SFPD has also had a strong presence in novels and short stories . Sidney Herschel Small wrote a series of thirty stories that appeared in Detective Fiction Weekly between 1931 and 1936 featuring Sergeant Jimmy Wentworth, the head of the Chinatown Squad, whose adventures were presumably based, if loosely, on the activities of Jack Manion , the real-life commander of SFPD's Chinatown detail.

The remainder of the force, viz., 54 men, shall be appointed as follows: By the Mayor, 2; by the City Marshal, 2; by the City Recorder, 2; and by the Aldermen and assistant Aldermen, 3 each. In July 1856, the "Consolidation Act" went into effect. This act abolished the office of City Marshal and created in its stead the office of Chief of Police. The first Chief of Police elected in 1856

6600-649: The Department of Justice concluded that there was significant racial bias in SFPD treatment of African Americans . A new study conducted by the California Policy Lab and researchers at the University of California, Berkeley , found that after the San Francisco Police Department doubled its foot patrols in late 2017, it resulted in a reduction by about 16% in larceny theft and 19% in assaults across

The school was closed for one year, shored up and reopened. It was closed as a public school in the 1980s. Subsequently, the building is used by the SFPD for training. It is surrounded by a heavily wooded forest area and is near a shopping mall and apartment complex. As of recently (2008), there are three academy classes in session annually, with individual classes taking place for 31 to 32 weeks, year round. Pier 94

The Dirty Harry film series is known for shaping the popular view of the department, with a hard-nosed stance on crime and often using "cowboy" tactics ( shoot first , stakeouts , and preemptive raids ). In the days of old-time radio , there were a number of drama series built around the activities of the SFPD. Carlton E. Morse created four different shows based on SFPD files for NBC 's Pacific Coast Network, Chinatown Squad , Barbary Coast Nights , Killed in Action , and To

6930-625: The SFPD Airport Bureau. SFPD was one of the last large agencies in California to adopt semi-automatic pistols. Starting in the early 1990s, officers stopped being issued .38 Special 6-shot revolvers. Instead, they were issued the .40 S&W Beretta Model 96GT (G standing for decocker only and T standing for Trijicon night sights), a variant of the Beretta 92 semi-automatic pistol. More recently, SIG Sauer pistols have replaced Beretta 96GTs as

Only managers and African-American officers remained on duty, with 45 officers and three fire trucks responsible for a city population of 700,000. Supervisor Dianne Feinstein pleaded Mayor Joseph Alioto to ask Governor Jerry Brown to call out the National Guard to patrol the streets but Alioto refused. When enraged civilians confronted SFPD officers at

7150-475: The State of California require some form of "drop safety" on all new firearms, which are usually passive safeties designed to reduce the chance of a firearm accidentally discharging when dropped or roughly handled. Such safeties generally provide an obstacle to operation of the firing mechanism that is only removed when the trigger is pulled, so that the firearm cannot otherwise discharge. Drop tests were introduced with

7260-410: The U.S. State of California passed legislation in 2006 requiring magazine disconnects on all new handgun designs sold in the state starting January 1, 2007, which has resulted in their widespread availability in other jurisdictions as well. The arguments in favor of a magazine disconnect are that if the gun cannot fire without a magazine, then an accidental discharge can be prevented if someone removes

7370-487: The US Civil War, had no internal safety to render them drop-safe, and were usually carried with an empty chamber under the hammer. Many original single-action revolvers have a half-cock "safety" notch on the hammer, but these are not drop-proof. Modern single-action revolvers, those made after the early 1970s, almost always have an internal safety, such as a hammer block or transfer bar. It is safe to carry such firearms with

7480-460: The ability to allow the user to select various fire modes may have separate switches for safety and for mode selection (e.g. Thompson submachine gun ) or may have the safety integrated with the mode selector as a fire selector with positions from safe to semi-automatic to full-automatic fire (e.g. M16 rifle ). Some firearms manufactured after the late 1990s and early 2000s include a mandatory integral locking mechanisms that must be deactivated by

7590-419: The action and normally positioned to prevent the hammer contacting the cartridge primer or firing pin when at rest. Similar to the firing pin block, the obstruction to the hammer's travel is removed as a consequence of pulling the trigger. This allows the hammer to contact the primer or firing pin only when the trigger is pulled. A transfer bar is also used in revolvers and some exposed hammer rifles, but works

7700-408: The base of the hammer, that allows the sear to catch and hold the hammer a short distance from the pin or cartridge primer, in a " half-cocked " position. The safety notch works first by allowing the handler to retract the hammer a short distance from the firing pin or primer, such that dropping the firearm on its hammer will not result in an energy transfer to the pin or spur, which could then discharge

7810-416: The chamber. Such devices have been in existence for decades; strictly speaking, loaded chamber indicators are not safeties, nor are they efficacious with an untrained user. Another form of warning is an indicator behind the ejector port that does not rise enough to disrupt a shooter's sight picture , but enough to be easily seen or felt to alert a user that there is a round in the chamber. The opposite of

As of April 2024, the SFPD was operating in a "reactive" mode (that is, reacting to 911 emergency calls)—meaning that it was no longer able to pursue violations of most traffic laws (especially infractions). From 2016 to 2023, the annual number of traffic tickets issued by SFPD fell by 96 percent, from 129,597 to 5,080. That month,

However, the act of cycling the action on such a firearm (as a natural consequence of discharging the firearm, or to chamber the first round) will leave the hammer cocked in single-action mode. To return the pistol to its safe state, it is necessary to uncock (decock) the hammer, usually by holding the hammer spur, carefully pulling

8140-629: The day-to-day operation of the bureaus. The department is divided into six bureaus which are either led by an Assistant Chief or Deputy Chief. The standard issue side arms issued by the SFPD are the SIG Sauer P226 chambered in .40 S&W. Officers also carry batons (straight wood/straight expandable), pepper spray, a portable radio and handcuffs, and certified officers are authorized to carry AR-15 platform rifles chambered in 5.56×45mm NATO on patrol. The SFPD has several types of vehicles in use, among them are Trek Bicycle Corporation bicycles ,

The department's motto is the same as that of the city and county: Oro en paz, fierro en guerra , Spanish for Gold in peace, iron in war . The SFPD began operations on August 13, 1849, during the California gold rush under the command of Captain Malachi Fallon. At the time, Chief Fallon had a force of one deputy captain, three sergeants and 30 officers. In 1851, Albert Bernard de Russailh wrote about

8360-562: The early 1960s, Breni James wrote two novels about Sergeant Gun Mattson, uniformed patrol supervisor at the Ingleside District Station, The Night of the Kill (1961), which was an Edgar nominee for Best First Novel, and The Shakeup (1964). Ernest K. Gann 's 1963 novel, Of Good and Evil , tells the story of one busy day in the professional life of San Francisco's police chief, Colin Hill,

8470-411: The federal Gun Control Act of 1968 for imported guns. A safety notch is one of the oldest forms of drop safety, used on older single-action revolvers manufactured before the invention of the hammer block, some lever-action rifles, 1911 -pattern guns, and hammer-fired semi-automatics that were designed before the invention of the firing pin block. The safety notch is a relief cut made in the tumbler at

8580-559: The firing pin. In addition some manual safeties such as the Ruger SR9 pictured lock the pistol's slide closed when in Safe position whereas, for example, S&W M&P manual safeties do not lock the slide closed. The benefit of these design variances have not been clearly stated or pointed out by manufacturers, however, in the Ruger SR example, a chambered round cannot be ejected to empty the gun with

8690-580: The first of which, Every Move She Makes (1999), won the Barry for Best Paperback Original, and the third of which, Deadly Legacy (2003), won the Anthony in the same category. Some San Francisco-set police novels have explored The city's rich history. With Siberia Comes a Chill (1990), by former Inyo County Deputy Sheriff Kirk Mitchell , features SFPD Homicide Inspector John Kost who, in April 1945, while conducting

8800-443: The full commitment on becoming full-time peace officers. A San Francisco Police Reserve Officer is a POST (Police Officer Standards and Training)-certified peace officer who volunteers his or her time. A Reserve Officer is classified as a Q-0 and has the same duties and authority as a full-time paid Police Officer while on duty. Officers patrol in vehicles, on bikes, on foot, and in some cases on marine craft. Reserve officers must meet

8910-456: The grip is subsequently squeezed. Finally, if both the grip is squeezed and the trigger pulled simultaneously, the pistol will fire. Another, unusual variant was found in the Ortgies semi-automatic pistols. To disengage the safety, a user would squeeze a lever until flush with the rear of the grip. The lever then would latch in the disengaged position until the user released it again by pressing

9020-488: The gun during or after the unloading process. With a magazine disconnect depressing the trigger into a bullet trap or other safe direction, such as downrange, will not clear the round in the chamber because the trigger is disabled. When an empty magazine is inserted the firing system becomes reactivated, even though the trigger has been previously depressed. The Sporting Arms and Ammunition Manufacturers' Institute stated that an "obvious concern with magazine disconnect features

9130-478: The gun has not only been fully and completely cycled, but the trigger is released and squeezed again. This defines the behavior of semi-automatic firearms which require a separate trigger pull to fire each successive cartridge and ready the next, and this is the preferred mechanism of disengaging the trigger on repeating-action firearms. Older pump-action shotguns such as the Winchester Model 12 did not have such

9240-546: The handler may decock the firearm by pushing down on the safety lever from the "Fire" setting, or engage the safety (even on a cocked firearm) by pushing the lever upwards. A simpler "two-way" system was popularized by the Walther PP and is also commonly seen on the Beretta 92 : engaging the safety also decocks the firearm. The SIG Sauer line of pistols, such as the SIG P226 , frequently feature decocking levers. The earliest use of

9350-418: The interlock helps prevent misfires due to a cartridge not being fully in battery when its primer is struck by the pin (known as firing "out of battery"). Passing handguns or rifles to another person with the action open (known as "show clear") is recommended by elementary gun safety . A magazine disconnect feature does not allow a user to fire the gun when the magazine is withdrawn (even partially) by means of

9460-399: The longer, harder trigger pull to cock and fire double-action provides adequate trigger safety, while keeping the firearm in a more ready state. A grip safety is a lever or other device situated on the grip of a firearm which must be actuated by the operator's hand, as a natural consequence of holding the firearm in a firing position, in order for the firearm to fire. It is usually similar to

9570-417: The magazine but forgets that a round has been chambered. Also, if losing possession of the firearm is imminent, the operator can render the firearm useless by removing the magazine. Firearms expert Massad Ayoob found instances where during a struggle, police officers carrying a pistol with a magazine disconnect were able to prevent being shot with their own guns by ejecting the magazine. One disadvantage of

9680-399: The magazine disconnect is that it may add tension to components of the trigger mechanism, making the trigger pull uneven or heavy. A safety argument against a magazine disconnect is that if a round is left in a chamber due to extractor failure or other reason the firearm will revert to being live unexpectedly when an empty magazine is reinserted. This is a danger because the user may dry fire

9790-567: The manual safety in the safe position. The safety must be OFF to clear the weapon. In the M&;P design, the slide can be manually actuated and a chambered round ejected with the manual safety in safe position. One possible benefit of the slide-safety lock may be that, upon holstering, the slide cannot be snagged and hung up out of battery. Manual Safeties are the oldest forms of "active" safety mechanism and are widely used; however, many "double-action" firearms such as revolvers do not have manual safeties as

9900-473: The nascent San Francisco police force: As for the police, I have only one thing to say. The police force is largely made up of ex-bandits, and naturally the members are interested above all in saving their old friends from punishment. Policemen here are quite as much to be feared as the robbers; if they know you have money, they will be the first to knock you on the head. You pay them well to watch over your house, and they set it on fire. In short, I think that all

10010-406: The nominees for these awards are reviewed by a board of police captains. A Meritorious Conduct Award can also be awarded to department members. The San Francisco Police Reserve Officer Unit is composed of individuals who wish to provide community service and give back to the city they live or work in. These officers understand the need for quality policing and community involvement, but cannot make

10120-403: The opposite way from a hammer block. The transfer bar has the spur that would otherwise be on the hammer, or encloses a firing pin similar to autoloading designs. The hammer itself cannot contact a loaded cartridge, but must instead strike the transfer bar, which then contacts the cartridge primer with the spur or pin. The transfer bar is normally positioned out of line with the hammer's travel, but

10230-413: The people concerned with justice or the police are in league with the criminals. The city is in a hopeless chaos, and many years must pass before order can be established. In a country where so many races are mingled, a severe and inflexible justice is desirable, which would govern with an iron hand. On October 28, 1853, the Board of Aldermen passed Ordinance No. 466, which provided for the reorganization of

10340-499: The picket lines, the officers arrested them. Heavy drinking on the picket line became common. After striking SFPD officers started shooting out streetlights, the ACLU obtained a court order prohibiting strikers from carrying their service revolvers. Again, the SFPD ignored the court order. On August 20, a bomb detonated at the Mayor's Presidio Terrace home with a sign reading "Don't Threaten Us" left on his lawn. On August 21 Mayor Alioto advised

10450-480: The police department. Sections one and two provided as follows: The People of the City of San Francisco do ordain as follows: Sec. 1. The Police Department of the City of San Francisco, shall be composed of a day and night police, consisting of 56 men (including a Captain and assistant Captain), each to be recommended by at least ten tax-paying citizens. Sec. 2. There shall be one Captain and one assistant Captain of Police, who shall be elected in joint convention of

10560-415: The required training prior to being appointed as a Reserve Police Officer. Once appointed, that officer must attend Continuing Professional Training, which is consistent with the requirements of regular full-time Officers every two years. There is also a 400-hour Field Training Program that Level 1 Reserves Officers must complete with a FTO officer. Reserve officers are held to the same performance standards as

10670-402: The safety. Most traditional semi-automatic double-action/single action (DA/SA) pistols are designed to be carried with the hammer down (uncocked) on a chambered round, with or without a manual safety engaged. The pistol is considered safe in this state as the "double-action" pull that both cocks and fires the firearm is both longer and heavier than the "single-action" pull that simply releases

10780-444: The same stringent and comprehensive POST standards and training as regular full-time police officers. Most San Francisco Police Reserve Officers are Level 1 Reserve Officers, which is the highest level that is recognized by the State of California. The SFPD does accept Level 2 or Level 3 Reserve Officers, but based upon their respective levels which determine how a Reserve Officer is deployed. Reserve Officers are responsible for serving

10890-660: The standard SFPD service weapon. As of September 8, 2011, ground was broken for San Francisco's new Public Safety Building (PSB) in Mission Bay. A replacement facility for the San Francisco Police Department (SFPD) Headquarters and Southern District Police Station, the PSB also contains a fire station to serve the burgeoning neighborhood. In 2014, the San Francisco Police Academy graduated its first publicly reported transgender police officer, Mikayla Connell. A 2016 report by

11000-410: The striker, and the mechanism is designed to have insufficient force to ignite the primer of an active cartridge from this state even if the sear lock and firing pin block both fail. Rifles come with various safeties. Some use a cross-bolt safety button, others a wing safety at the rear, or even a "half-cock" notch (such as found on older lever-action rifles). The Winchester Model 94 originally utilized

11110-423: The trigger is depressed. Third, as with most pistols, a firing pin block actuated by the same extension bar prevents the pin coming into contact with the primer unless the trigger is pulled to clear the block. Although not generally considered a safety feature, the resting state of the gun (excluding a dry/misfire) has the striker in a "half-cocked" state; pulling the trigger will fully cock the weapon before releasing

11220-399: The trigger, and then slowly lowering the hammer on the firing pin. Hammer-fired semi-auto pistols have a beaver tail to protect the shooter's hand from the slide, which makes it more difficult to securely and firmly grasp the hammer with the thumb than a double action/single action revolver, thus making an accidental discharge more likely. Striker-fired pistols, on the other hand, do not have

11330-593: The unit by the Inspectors. The SFPD was one of the founding departments in the field of utilizing Police motorcycles (along with their counterparts across the bay in Berkeley ). The unit was founded in 1909, and has grown ever since. They are officially under the command of the SFPD Traffic Division . They participate in many duties such as traffic enforcement, patrol, riot control, and special events and escorts. It

11440-402: The user) and external safeties (which typically allow the user to give input, for example, toggling a lever from "safe" to "fire" or something similar). Sometimes these are called "passive" and "active" safeties (or "automatic" and "manual"), respectively. External safeties typical work by prevent the trigger pull or prevent the firing pin from detonating the cartridge or both. Firearms with

11550-400: The video game Watch Dogs 2 was released. The Mentalist character Teresa Lisbon is former SFPD. The character of Beau from Colony is a 30-year veteran of the department. Municipal police Municipal police , city police , or local police are law enforcement agencies that are under the control of local government . This includes the municipal government , where it

11660-464: Was James F. Curtis a former member of the San Francisco Committee of Vigilance . The SFPD is one of the pioneering forces for modern law enforcement , beginning in the early 1900s. In early August 1975, the SFPD went on strike over a pay dispute, violating a California law prohibiting police from striking. The city quickly obtained a court order declaring the strike illegal and enjoining

11770-600: Was at its peak in the mid-1970s, with the number of helicopter and small plane flights rivaling the frequency of the Los Angeles Police Department. After several accidents (one of which a helicopter crashed in Lake Merced, killing Officer Charles Logasa in 1971) and complaints about the "Eye in the Sky" program, the unit was disbanded. The helicopter unit was featured prominently in the first Dirty Harry film, identifying

11880-607: Was built in 1895 and was located on the West End adjacent to Golden Gate Park . The building, no longer in use, had the facilities to accommodate 25 trainees. In the 1960s, the building now used as the San Francisco Police Academy Complex was built originally as Diamond Heights Elementary School located at 350 Amber Drive, just behind the Diamond Heights Safeway. The building was built in the 1960s hugging

11990-554: Was formed as an offshoot of the department in 1938 to patrol the various housing projects of the city. In the 1990s they were completely absorbed back into the main Police Department. In the mid-1990s, San Francisco experienced the explosion of drug-related homicides, which escalated to approximately 40 murders. Then-Chief Fred Lau sought the expertise of his veteran homicide Inspectors, Napoleon Hendrix (now deceased) and Prentice "Earl" Sanders (later Chief of Police), to put together

12100-557: Was located at the San Francisco Thomas J. Cahill Hall of Justice at 850 Bryant Street, which houses a number of criminal courts, jail facilities, investigative and support units, as well as "Southern Station". The Headquarters of the San Francisco Sheriff's Department is housed in an adjacent building. On April 16, 2015, the SFPD officially moved its headquarters to a new location at Mission Bay . The SFPD has been portrayed in films such as The Sniper , Vertigo , Freebie and
