the police should take care of that. In my area, they give you a warning and then start to fine you. It adds up pretty quickly. If they person becomes a repeat offender, you typically no longer have to call them. The guy ends up being on their "watch list" and part of their daily routine. hey, its a revenue opportunity.
In my 'hood, they just deployed license plate reading cameras. It reads your plate, checks the records, and if you have an outstanding ticket, a car is deployed. it is big brother scary but ends up being better for you in that it weeds out troublemakers pretty quickly.
it is also common to have police cars drive around parking lots with these license plate scanners. To serve and protect!
