I am thinking he may be LE, but more likely a whacko.....could you tell if he was wearing a vest??? Most LE I know have their vests on if they are carrying open because it attracts undue attention. Also, most of em don't wear gas station T-shirts stating "special ops"
In TN, its legal to carry either way, and I'm all for people having the right to decide, but I just don't understand why anyone would want to attract the attention it does (in public). It is far better to be armed and concealed because if you get into a bad situation, the element of surprise on the bad guy is the advantage IMO
Clearly no vest.
