Not many people have seen it, but one of my favorite movies is Interstate 60. It has a story thread through the movie, but what it really becomes is a series of essays on freedom and slavery. One the best parts is the town where everyone is a lawyer. The only way anyone makes money is when someone breaks the law, so their laws are crafted such that it is impossible not to break the law.
The town of Jericho, Arkansas sounds very similar. It has 174 residents, no businesses, but a police force of 6 that tries to find ways to support itself. Apparently, everyone in town is constantly in court for traffic citations. When one man got fed up, and yelled at the police in court for their stupid speed traps, the police shot him - right in the courtroom. In a scene right out of Interstate 60, the DA, after investigating the shooting, couldn't remember the name of the police officer who did the shooting and said no charges would be filed against the police, but that misdemeanor charges were being considered against the man shot. Probably for littering, due to his bleeding on the floor.
