I don't agree with it. Shooting people in the back is WRONG. His life was not in immediate danger when those shots were fired. His property perhaps, but NOT his life. Like I said earlier, the only time something like this could be justified would be (for example), a burglar is rushing at me with a knife, and my roommate, friend, family member etc, fired the gun and shot him in the back to protect me and keep me from being killed. Shooting people in the back when life is not being immediately threatened is wrong wrong wrong.
I know I'll be torched for saying this, but I'm going to do it anyway. This is the reason I think guns should be illegal in this country. Too many trigger happy people... "Shoot now and ask questions later". That sort of attitude doesn't wash with me. Sorry. I have never agreed with it, I don't agree with it now, and I doubt I ever will.
As you can probably tell, I am NOT from Texas!
