Does crime pay?
It's true that one who commits a crime has little change of being caught. It's also true that if he's caught there's little chance he'll be convicted. If convicted there's little chance of his doing time. If he does time, there's little chance of his serving his full term.
These are well-known facts which encourage criminality. But what most people fail to realize is that the entire criminal justice system itself is one of the greatest industries in our country.
