Unfortunately, or fortunately depending hiw you look at it, we have the freedom to be stupid in this country. My problem with your assertion is that characterized the guy you saw as a rogue cowboy, out looking for trouble. You have no idea whether he had a permit or not. You have no idea hie skilled or trained he was. I cringe when I see people open carrying. It used to really bother me. Not so much anymore. I saw a guy open carrying in a Walmart. I asked him "Why do you feel the need to carry openly? You realize you're not doing us any favors? And before you answer, I'm a huge 2nd amendment advocate and believe you have the right to do what you are doing, but why are you doing it? You may provoke someone into a confrontation that wouldn't have happened otherwise." He answered politely, "It's quite the opposite actually. People want to stay away from me. No one wants to ef with me. But that's not the only reason, I don't always carry openly but sometimes I find it easier and more comfortable to carry OWB than IWB".
I've got friends, with a whole lot more training than me that carry openly. Some are permitted, some are not. That little bit of training that you get for your permit makes no difference to me.
I've had the unfortunate experience of having to hold someone at gun point. It took everything in my body to point that gun at him. As a matter of fact I would lower it unless he was moving toward reaching under his seat. I begged him to stay still that I didn't want to shoot him. Fortunately, the cops showed up and took care of the situation.
I seldom carry, I keep a gun secured in my truck and have it if I find myself in a situation that I'm uncomfortable with.
Also, I want to.be clear, I don't think the guy should get off scott free. I just don't think he's a criminal. I think he should be sued in civil court as I suspect he will be.
