@OmSigDAVID,
David, never, not once in my life have I wondered why somebody didn't shoot someone, in fact.. There have been many times in my life I've wondered why someone was shot. Or conversely, I've often wondered why people insist on fighting and not fleeing. If someone is threatening me, I do my best to walk away and NOT make the situation worse.
In your little scenario, your fella sat there and took the punch. Why didn't he defend himself, why didn't he drive away. There are plenty of ways to defend yourself without a gun. I've been trained in self defense, I could probably disarm you within seconds, even with all your training. I'd never take the chance with you though, cause I think you're the kind of guy who shoots before he thinks, but I can't be certain of that. Thankfully I don't spend a lot of time in the states and have managed to live a fairly safe, gun free life.
I chose to live my life without guns. If I live to regret that decision, C'est la vie. At least I've lived this long and I could find out tomorrow I'm dying of a more insidious disease or be hit by a car. One never knows, but I'd prefer to be happy that paranoid.
I do know several children who were shot and/or killed in my life time. These were the children of good, law abiding citizens. The parents were trained in the safe handling of weapons, and yet, didn't.
The only adults I've even known that were shot or own had guns we're gang affiliated and the guns were purchased illegally and brought up to Canada illegally.
I don't give a rats ass about a perpetrators health, but if you bring a gun into a fist fight, you deserve to go to jail.
