A guy near me open carried an AR into a JCPenny a couple weeks ago. It wasn't loaded and I guess nobody freaked out or called the police. Some girl in line behind him took a few pictures with her phone and those went viral. It was from those pics that the police first heard it even happened.
Some people are like a Slinky .. not really good for anything, but you still can't help but smile when you shove them down the stairs.
