>[P]eople might want to keep a bad law if they continue to make money by snitching. In fact, money is the exact wrong incentive for this sort of thing.

I've said elsewhere the optimal mechanism here is for that money to be paid to the snitcher, from the person who is being turned in. This would lead us to assume that for most crimes of a personal nature, we would have about as many people losing money due to the law as making money due to it, and so the effect cancels out.

In situations where many more people make money and only a select few are losing big, well... Somehow I feel like that's usually for the best anyway. See my other comments on eg the runaway success of the False Claims Act. Or just consider the class action lawsuit and whether you think it fills a valuable role in society.

>Think a little harder and see if you can imagine why a law that isn't strongly enforced still might exist.

Thanks for letting me pick the reason, that's very thoughtful of you. Obviously it's because said law being strongly enforced would cause such a public backlash that it would quickly get repealed in its entirety, and thus further erode the monopoly on violence the state holds over its citizenry. Cops then have fewer en passants they can pull when they don't follow procedure, etc etc. I'm glad we're in agreement on this.
