Why would he chase him down? No idea! Why did he punch him? Do you know that? Nope. Me either.
I agree, think first, act second. That doesn't always happen. If you think people who carry guns are immune to anger, shock, and the fight or flight response, then you are wrong.
I will reply to the statements you made in other posts. Though I didn't know it was required of me. Pepper spray, gun, club, fingernails.....whatever! My only point is that I believe it's wrong to judge this man's response based on the very little information we were initially given. Of course, there are times when retreat or not drawing or using a gun is the best solution. Never said that was NOT the case. Additionally, if I didn't have a gun, then (as I stated in previous posts) my response to being punched in the face would depend on the circumstances. I may run for my life. I may pepper spray you. I may kick you in the knee. I may cry like a little girl.
I do NOT understand why anyone (again, given the initial report and its VERY limited details) would be so quick to judge someone for defending themselves with a gun. He didn't shoot into the crowd. He didn't shoot at all. He stopped the assault by drawing his weapon.
As for your last sentence. You can infer whatever you like about my opinion. However, I have been carrying a firearm for many years. I am law-abiding and like to think that I use sound judgements. I have never had to draw my weapon to solve a problem. So....NO every problem isn't a nail just because I have a hammer! GOOD LORD
