These are situations that wouldn't get that far if the defender was equally armed. Also, yes... People can shoot attackers before they shoot them (if they have a gun, that is ). The attacker might not even know how to shoot; might not know how to maintain or even fire the gun... much less aim it carefully and accurately. Their first shot(s!) might not hit; but you make sure that yours do.
