So, if a dude was going for a gun, would you consider that enough of a threat to warrant shooting him?
Me? I'm a product of the "late" 1960's, so maybe I could just plead: "Hey Dude, Why So Angry?"
You know, talk him into a peaceful place.
Unfortunately, I split the 1968-1970 years in an un-peaceful place. So I was never, like, really into the "Easy Peaceful Feeling" thing. Like, y'know man?
Best response I can come up with is:
(1) OPEN CARRY MAKES YOU A TARGET and
(2) AT MY AGE, THERE'S ONLY TWO KINDS IF FIGHTS; THE ONE YOU WALK AWAY FROM, AND THE ONE YOU DON'T.
Walk away if you can.
It beats the hell out of crawling away.
