Revenue Collector
Any police officer that writes traffic tickets. Most communities use revenue collectors and traffic court judges to shakedown motorists for money. It is not about enforcing the law, but collecting revenue for the city or town where the ticket was issued.
The state of Illinois passed the seatbelt law. This law allows revenue collectors to write more traffic tickets thus generating more revenue for there communities.
