So they're useless for crimes not involving a reported license plate? Sounds like a pretty worthless marginal gain. The Chinese have done it better since their mass surveillance apparatus isn't contingent on reported license plates, or even the involvement of a vehicle. Start a fight on the street and they'll find you. Is America really this incompetent that they can't match a 10+ year old system?
So what you're saying is that I can report your[1] car as being associated with a crime, and the police will show up wherever you and/or your car is and treat you like a criminal?
