Obviously you don't.
It's also obvious that you and the other right-wingers think it's fine when innocent by-standers get killed. And lack of experience is NO excuse. They are taught discipline and when someone yelled to shoot, they obeyed, without regard to whom they were shooting. They evidently didn't give any more of a fuck who they shot than you Repugs care that bystanders get killed. You're a piece of work. I'm sure if your sister or brother had been shot, you'd be right on the sidelines yelling, "Right on! You hippies don't have a right to live!"
