I'm responding directly to the comment above, asking which crimes they might have unintentionally committed.

You'll notice I make no comment about the kickbacks here.

And yes - the whole POINT is that none of these are all that intuitive, and they vary by region. So the odds are very good that you're violating some city/town/state ordinance fairly often, but the lack of enforcement means you never consider it.
