The Gotham City Police Department is the local city law enforcement agency for Gotham City.
Acting as both ally and opponent of Batman, the Gotham City Police Department has long been steeped in political corruption, with numerous officers both high-and-low ranking involved in bribery and even more serious offenses such as drug-trafficking and murder.
During the events surrounding Batman's rise as Gotham's defending hero, Police Commissioner Gillian B. Loeb was under the bankroll of Carmine Falcone, mafia boss of the Falcone family, who made sure Loeb and his forces did not interfere with his operations.
Willfully working with Falcone, Loeb was targeted by Batman amongst other underworld figures. Ordering a massive police taskforce to capture the Batman at all costs an increasing amount of conspiracy charges, brought forward by District Attorney Harvey Dent, against Loeb forced him to resign his position, he was replaced by equally corrupt Commissioner Peter Grogan.
After the death of Carmine Falcone, the mafia lashed out in retaliatory crimes which severely crippled organized crime in Gotham City. As a result the waning presence of corrupt police officers on the force allowed Lieutenant James Gordon, a man determined to fight corruption in the GCPD, to become the new police commissioner.
Gordon served as commissioner for a long period, assisted by the Batman in bringing justice to Gotham until a near fatal gunshot from a corrupt cop forced his retirement.
His successor, Commissioner Michael Akins took a less lenient approach with Gotham's vigilante heroes and ordered the shoot-to-kill order of Batman and the estrangement of the police force from the hero's activities. Corruption within the police department rose once again during Akins' tenure as Commissioner before he was replaced by Gordon's return to the post of Commissioner and relations with the Batman were reestablished.

- In designing the GCPD's look for the game, Chuck Dee reasoned that, due to the rampant corruption, the police didn't have much money to spend on updating their equipment and so instead turned to fixing and modifying equipment already possessed. A majority of designs, from vehicles to uniforms, were influenced from versions in the 1970's, updated to appear tough enough to stand modern usage in the field.
