Don't know, years ago, in SC, the elected sheriff had to only be elected to be sheriff. Now, evey dude issued a state owned gat & badge must have gotten state sanction cop training and then swear an oath to become a good minion of the state. Not all cops take a oath to support and defend the US Constitution.
Sounds like you had a wee bit of fun.
I told a cop who pulled that get a CC permit, when we both happen to be getting coffee at the local QT, and then cover it up crap, in a nice way, to cover his, it made me nervous. He kinda lost interest in the conversation at that point. I know he thinks he is trying to provide sage advice, but he obviously was not going to consider my sage advice either.
