New gun owner with OC/CCW questions and concerns

[Kevin108]

If I'm a perp and I am about to rob or wreek mayhem in a business and I see someone open-carrying, step #1 is to walk up behind him and pop him in the back of the head. RIP, he was a patriotic, pro-gun, card carryin' patriot-- but a dead one.

Show me an instance of this ever happening to a non-LEO. Even if you find one, you are statistically more likely to be struck by lightning.
