I'm reminded of this from Atlas Shrugged:
Theres no way to rule innocent men. The only power any government has is the power to crack down on criminals. Well, when there arent enough criminals, one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws. Who wants a nation of law abiding citizens? Whats there in that for anyone? But just pass the kind of laws that can neither be observed nor enforced nor objectively interpretedand you create a nation of law-breakersand then you cash in on guilt.
