Come on...
72IH...don't worry about these other guys opinions, you did what you thought was right at the time. And you weren't wrong for having your guard up. We SHOULD support others who choose to carry safely, that is true. But if you don't know the guy personally, you don't know what his intentions are, maybe he would have started trouble. You can't ASSUME that a person who looks like a good guy carrying legally IS a good guy. You don't know him! Making assumptions can easily put you in deep trouble. Many serial killers and rapists blend in to society because they look like normal people. You were right to just stay cool, not assuming he was a lunatic but not assuming he was a decent, normal guy. Chances are he was a good guy carrying just like you, but you can't bet your life on that. You were simply AWARE, which is the best thing to be in my opinion.
