up next, man who wouldn't sell gun to Mexican looking dude being charged with discrimination.
Lol.
I almost got into this situation awhile back.
I was at a gun show, trying to sell my Glock 21. I just had a sign on my gun case, stating what it was, and how much I wanted. Some guy with shorts halfway off his *expletive deleted*ss and white socks pulled up to his knees, and a So-Cal T-shirt came up and asked me to see it. I took one look at him, and told him I'm only interested in selling to people with AZ Concealed Weapons Permits.
Oddly enough, he didn't have one.
It makes for a good way to stop a gun sale if you don't like the look of the purchaser.
I ended up selling to a soccer-dad looking guy, who did not have a CCW, but did show me a valid AZ driver's license and sign a paper for my own edification that he was a legitimate purchaser by all applicable state and federal laws.
I'm sure someone will be along to tell me what a racist bigot I am, but I'm pretty well convinced that my G21 would either be in Mexico or a police lock-up by this point had I sold to the first guy at the gun show.
