Police Computer

The police computer is an interactive computer found on board most law enforcement vehicles in Grand Theft Auto IV, two episodes, and Grand Theft Auto: Chinatown Wars that provides access to Vigilante-like side-missions and a small criminal database.

Description

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 and hunt down most wanted criminals, monitor and respond to recent crimes in the area, search through a small database of criminals in Liberty City, or even call for backup. Note: In GTA IV, searching for "Niko Bellic" will not yield any results.

Supported vehicles

Although the police computer is assumed to be standard on all road-based law enforcement vehicles (except bikes), this is not the case in reality, as certain models do not come equipped with it; a significant number of law enforcement vehicles in GTA IV may also lack an actual police computer in their interior despite allowing the player to access one.
