I got hit by a car in a hit and run, and despite there being dozens of cameras, and me getting the footage of the car hitting me and driving off (not clear shot on license plate), the police immediately called it a cold case and refused to even try to get footage from any other cameras nearby - so I'll hold my breath that they use this for anything to prevent crime.
