Lawlessness

A common refrain in most court rooms and police precincts is that ignorance of the law is no excuse for bad behavior. Some of it is self-evident, for example: most people are pretty sure they have broken more than a few laws if the babysitter's head winds up in the lettuce crisper. While that one is pretty much obvious, depending up on where you are standing, there are probably a whole host of obscure laws that can make your life hell and cost you money if you find yourself in violation.
