The cops are normally referred to by the gangs as "pigs"; a common derogatory statement for a police officer. They are shown to be quite corrupt, for example, they are said to have 'gotten into' the looting that took place during Blackout.
Depending on the difficulty setting, and the crime, they usually respond to calls in big numbers. Robbing stores will set an alarm, and two will usually come, or if they're called for a fight, or a mugging, just one.
At any moment when not engaged in combat, if they feel the need to call for back up, they will take out their talkie and call for dispatch, which can make it hard for stealth missions.
Their A.I. is exceptional, and will not intervene when two gang members are fighting each other. Although they cannot climb or run as fast as the player, they will stop at nothing to catch you, including throwing their nightstick, if on higher ground.
- They were the only cops to not to use their guns in a Rockstar game. With the exception of Bully, which was released a year later.
- In the game, if you grab and toss someone at a cop, the cop will fight and arrest the person who was tossed onto the cop, except civilians.
