For you, one size fits all. If he doesn't comply, he must be in a psychotic state, with a weapon and charging even after being shot. None of this was the case in this situation. He didn't show a weapon anb didn't charge, especially after being shot the first time. He dropped right away. If police officers don't have the brainpower to be able to assess situations, then they shouldn't be police officers.Unless of course the person is under the influence of intoxicants, or in a motivated or psychotic state. In that case, such people have been known to shrug off multiple gunshots and keep going. For those people, pain compliance isn't a good option. It also requires the cop to be withing 20" to hit him. Thats close.
Plus, if you can't hit someone charging at you at a distance of 15 feet while continuously having aimed your handgun at him, you should get another job. He never charged the officers, and he didn't have a weapon.
