At the Liberty City Department of Justice we use our LCDoJ Services Mod. Its a complete in-game computer, that connects to our database on our website and even creates a database of people you have had contact with. It also features real time updates to your fellow officers and dispatchers that are not in game. Its custom on board ALPR locks the vehicles and places it in your report for automatically. Unfortunately our developer has not informed me of a public release but maybe one day!
