Someone has to be shot at first, may as well be me. I've always been told that I 'look military', even when I had long hair and in highschool; I frequently wear military related shirts and hoodies, and have a high&tight cut, so if you're looking to take down what looks like a hard target I'm probably going to be your first pick anyway. I don't go to bars anymore because even before I joined the service I was the first guy that punk trying to impress is girlfriend came after. It's something I've just learned to deal with.
When I OC people just assume I'm a cop. Chances are you might assume the same even if you don't see a gun because off duty cops CC too.
