Capable? Most police are not that accurate on the range much less the field. Even the ones that are can miss in a highly charged situation. You can train all day for a high stress shooting but until you are in one you have no idea how you will react or be able to control your weapon. They are taught from day one to shoot center mass since that is the largest target and has a better chance of stopping the threat. Head shots are a fool’s errand with a pistol at more than 3-5 feet in a high stress situation. Shooting at legs, arms, hands, feet not only runs the risk of a miss, but also ricochets and the miss that travels down range.
Ya gotta ask yourself.
Do I wanna kill this punk or just piss him off?
