I agree with Ben Towe in the post above. In a situation like this, although ill advised in the first place to be in this situation, with circumstances considered the shooting was appropriate to me if he feared for his life which he did and then proved in court.
I believe someone said he had no right to shoot him unarmed. He did it, was charged with murder, and was acquitted on the grounds of self defense, so he did have some right to shoot here obviously.
I've never been in a fight since I've started carrying and don't plan on every being in one, I'll either run away deescalate as much as I can or do what I need to defend myself.
As to the parties involved, both these guys were asking for trouble based on all the info and although the shooter was acquitted in this case it does not seem like he should be carrying a gun if he's introducing himself into situations like this. Ain't nothing like a women to get a man acting crazy. Emotions and guns don't mix. Leave 'em at home when you strap on and walk out the door.
