Years ago I was told that the average law abiding citizen broke at least a half dozen laws, regulations, codes, statutes, etc. every day. For a while, I would look at the human interest photo in the local paper, and find what laws were being broken. Example, a college kid giving his friend a haircut. We would probably know that the kid giving the haircut was unlicensed, thus a lawbreaker, but the kid getting the haircut was also a felon. Take a look at your local codes. I’ll bet that you or your neighbor don’t strictly adhere to the established rules concerning your garbage cans.
