I'm absolutely with lonestar.
The guy who taught my CCW class did something I think was very smart. He skipped escalation of force and went straight to deadly force. That's a yes or no question, not a 'maybe' or 'if' question.
I conditioned my thinking to assume that if I ever pull to do business, I must be able to convince a jury there was no other option. If this means I have to take a black eye, a busted tooth, or a maybe a broken rib because I didn't have the circumstances lined up, so be it. BUT, if a reasonable person would believe that it wasn't going to end there, It's going to go all the way.
If a pipsqueak who is significantly smaller than my average 5'10", 180, walks up to me and pops me in the eye, I'm not going to draw. But if I'm visiting my hometown, and I draw the ire of the guy who was the high school bully, is now 6'2" and close to 300, whom I saw smash a kid's head into a wall causing injury and massive blood loss during my senior year, gets his finger in my face and starts backing me into a wall, and doesn't even hear me say "Man, seriously, you need to back off," something very bad could happen.
I have had more than a little martial arts training, but if I were that sure it is sufficient, I wouldn't be carrying, would I? They guy who trained me competed against and beat Jim Kelly back in the 70s. He STILL carries.
And yes, bars are nasty places. And yes, I do sometimes go places I wouldn't go if I were unarmed.
Let's lighten up on the guy a little, he asked the question for a reason, let's try to be helpful, not question his motives and resolve.
I recommend, talk to your AG's office.
