This is like concealed carry class 101. The ONLY reason for pointing a weapon at someone is because you are about to shoot them with it. It’s a last resort. By the time you’ve drawn your weapon you had better have made up your mind that you’re going to kill the assailant because that’s the immediate next step. No warning shots. No last words. Draw. Aim. Fire.
It is not a “deterrent”. It’s the “I have no viable escape routes so deadly force is necessary.” option.
