The real reason is because our laws and system have become so corrupt that even enforcing something like this could even possibly wind you up getting sued. When I was growing up if you got caught they would detain you and it possibly could wind you up in jail depending on the crime. When I was a teen, and I'm telling on myself here, I was caught red handed stealing some batteries, probably D or C cells I think, at the local K-mart. Yeah I know I'm a criminal. They actually detained me and CALLED the COPS!!! I wasn't arrested, but I tell you what, I NEVER stole another thing in my life after that! I also stole a Hershey candy bar when I was 5 y/o and I think a bottle of men's cologne in my teens. So there, it's all out now. Boy I'm so relieved. I've been wanting to confess that for years. Btw, my own cousin caught me with the candy bar and made me take it back.
