You are missing the point. A rock being thrown at you is certainly deadly force, just as a baseball bat being swung at your head. Just because something is lower tech than the weapon you carry does not make it any less deadly.
These guys not only held their fire, they didn't fire back until after they were hit in the head at least once by a rock.... They were clearly acting in self defense, and while the press I am sure will try to spin it.. did the absolute right thing.
Self defense is an inalienable right, it doesn't matter if the person is using a weapon from the middle ages against you... or the latest high tech personal firearm... you have the inalienable right to defend yourself.
No sir, you have. Go back and re read my first post and the post I was responding to. I never denied that a rock can be deadly, I only aserted that a bullet is more so.
