I agree with you on what said above, but also impressive is his weapon control . The muzzle is always on target in the direction of the threat. Someone has trained him , even when on the ground being assaulted. His shot registration is better than many, for the number of shots fired and the so called “disadvantage” of his gun at close range. Am I wrong in what I see from the videos?

The best self defense evidence will be the attempt to set him on fire with a Molotov, and the guy with the pistol going from surrender position to lunging for the rifle. He would have killed him if his arm didn’t get blasted.
