I like your restaurant analogy but I draw the opposite conclusion. Imagine a restaurant which has a sign saying, "You must be dressed appropriately to enter - no shoes, no socks, no service." A family goes in to dine. About halfway through their meal, the cops come and arrest the father. Turns out, although nobody noticed at first, he wasn't wearing socks, and was therefore trespassing according to store policy. Is that fair though? It's one thing to ask the family to leave, but should the father be charged with an actual crime for unauthorized entry?
