gt -- You have to admit that in the specific situation shown in that video, the officers clearly made a poor choice to approach when there was literally the entire outdoors available. If you had no less-lethal option through which to disable, would you keep approaching an clearly agitated knife-wielding EDP?
As for pelvic shots, I've never met a single person who's been in a gunfight who claimed his victory occurred as a result of landing incapacitating wounds to the pelvic bone.
