Police computer search database

The police database is the storage of all known criminals in GTA IV, though the search itself is time comsuming you can search and locate most criminals in the game.

there are two ways you can search the database:

Search by name
When you search by name the user gets a virtual keyboard he/she can type names into, or connect a usb keyboard and use it to type. otherwise on the PC verision you simply type in the name.

this is used in early missions.

Search by photo
Search by photo is the other method, it connects to the user's phone and find photos where it identifies faces, this is used in the later missions.
