The Police Computer is an interactive computer found on board most law enforcement vehicles in Grand Theft Auto IV, Episodes from Liberty City, and Grand Theft Auto: Chinatown Wars. It provides access to Vigilante-like side-missions and a small criminal database. It uses Pro Tech software.
When the player is stationary in any police vehicle they can access the police computer by pressing the L1 button (PlayStation 3), the LB button (Xbox 360), or the E key (PC), allowing the player to search through a small database of criminals in Liberty City or call for backup. Only in Grand Theft Auto IV can the player search and hunt down most wanted criminals, and monitor and respond to recent crimes in the area through the police computer.
In Grand Theft Auto: Chinatown Wars, the police computer's functionality is limited to only allowing the player to respond to crime on the island the player is on.
Although the police computer is assumed to be standard on all road-based law enforcement vehicles (except bikes), this is not the case as certain models do not come equipped with it; a significant number of law enforcement vehicles in Grand Theft Auto IV may also lack an actual police computer in their interior despite allowing the player to access one.
