Law enforcement organizations

A law enforcement organization is an organization of parties, either individuals or other organizations or both, associated with law enforcement, typically with some common interest.

Described below are examples of various law enforcement agencies and police services.

Carabinieri
The Carabinieri (formally Arma dei carabinieri, "arm of carabineers" or "corps of carabiniers") were the official military police of Italy, policing both military and civilian populations. It was initially the police force of the Kingdom of Sardinia, but after the Italian unification, it became the First Force of the new national police force. They were both responsible for enforcing Mussolini's Fascist views by suppressing opposition as well as directly responsible for his downfall when Nazi Germany split up and disbanded the unit, many of them joining the resistance forces. By 2001, they acted as one of the four arms of the Italian military.

In 2015, the Carabinieri requested the aid of the PMC Maverick Security Consulting, Inc. to retrieve three Albanian mafiosos who had escaped to Montenegro. Raiden and Kevin Washington were assigned to the mission, although unexpected circumstances occurred when it turned out that the mafiosos had also cyberneticised themselves.

Denver Police Department
The Denver Police Department (DPD) is the primary police department for both the city and the county of Denver, Colorado. It was divided up to six patrol districts, with 3 sectors to each district, numerous precincts each district, and each precinct has one police squad car assigned to a unit of one to two cops. Although it provides full duty to the entire county and city, it in special cases also may provide contractual police service to other counties.

Because of small-government legislation enacted by then-state senator Steven Armstrong slashing the government budget, the Denver Police Department ended up being acquired by the new largest PMC in the world, World Marshal, Inc., As such, although most of the police force still retained regular humans for regular duties, the DPD's SWAT division, primarily combat specialists and hostage negotiators, were composed of military-grade cyborgs. In addition, although a few of the cyborgs were former United States military, others were foreigners who received cybernetic treatment as their "green card" for United States citizenship, in order to keep the nativists happy.

In 2018, members of the World Marshal-owned DPD ambushed ex-Maverick member Raiden (Raiden had abruptly resigned from Maverick earlier) on the highway to the downtown area of Denver, resulting in a chase and eventually some of the police (themselves cyborgs) firing a RPG at Raiden's car, consequentially getting Raiden over the police barricade. A six-man unit, plus two RPG cops, then attempted to use lethal force on Raiden both due to his illegally trespassing the area under both state and federal law, and his apparently threatening a peace officer. However, Raiden managed to wipe all of them out with little effort and also killed an advanced Desperado cyborg that somehow got involved in the attack before continuing on to the World Marshal HQ building.

Federal Bureau of Investigation
The Federal Bureau of Investigation (FBI) is the primary unit in the United States Department of Justice, serving as both a federal criminal investigative body and a domestic intelligence agency. The FBI has investigative jurisdiction over violations of more than 200 categories of federal crime. Its motto is "Fidelity, Bravery, Integrity," corresponding to the "FBI" initialism.

Hal Emmerich, while a college student, was recruited into the FBI under the ERF (Engineering Research Facility). However, at some point later, he was kicked out after he was caught monitoring and hacking the FBI's central database.

Psycho Mantis had a brief stint with the organization working as a Psychic Investigator. He would enter the minds of suspected killers and uncover the truth about their crimes. This eventually drove him psychotic and he later quit the Bureau and eventually joined FOXHOUND.

Naomi Hunter made up a false story about how her Japanese grandfather became assistant secretary to J. Edgar Hoover in the FBI and went undercover to help bring down the Mafia in New York, during the 1950s. Master Miller (who was really Liquid Snake) later revealed this was false as J. Edgar Hoover was a well known racist which meant there were only white FBI agents in his time as Director (1924-1972), and the Mafia undercover operations first started in Chicago in 1960, not New York.

The FBI agent who exposed President Nixon's involvement in the Watergate Scandal used the alias "Deepthroat."

While Master Miller (Liquid Snake in disguise) was trying to convey his suspicions about Naomi Hunter by pointing out various flaws in her backstory, he claimed that he used to work for the FBI. As Solid Snake stated that he was unaware of this, this may have been a lie crafted by Liquid Snake.

Federal Security Service (Russia)
The Federal Security Service of the Russian Federation (FSB) is the main domestic security agency of the Russian Federation and the main successor agency of the Soviet Committee of State Security (KGB).

In 2018, after a coup occurred within Abkhazia that resulted in a Russian refinery plant being confiscated, the FSB contacted the PMC Maverick president, Boris to take care of it, although he planned to take care of it anyways, as the Abkhazian people needed the help, and he and the other members already encountered the PMC involved in the coup, Desperado, in an earlier mission.

New York Police Department
The New York City Police Department, established in 1845, is a United States municipal police force, with primary responsibilities in law enforcement and investigation within the five boroughs of New York City.

On April 29, 2009, NYPD forces responded to the developing crisis at the Big Shell offshore plant, monitoring the situation from the cordoned-off Verrazano Bridge, and deploying patrol boats into the harbor to stop sea traffic. Peter Stillman, a former member of the NYPD's bomb squad, was called on to infiltrate the Big Shell with SEAL Team 10, and assist in clearing the C4 explosives planted on board. The following day, officers of the NYPD Emergency Service Team attended the crash site of Arsenal Gear in Manhattan.

Behind the scenes
In Metal Gear: Ghost Babel, the FBI had previously attempted to arrest the "Spectre Killer," but he instead became the member of Black Chamber known as Marionette Owl, at Black Arts Viper's request.

Even though various characters and cars explicitly refer to the Denver Police Department in Metal Gear Rising: Revengeance, some of the police cyborgs' tactical vests have the words "International Police" on them.
