Sorry @mieseratte, what you say is true. I exaggerated. Looking at the videos now though the boy was armed with a swimming float as a shield and a relatively thin white (plastic??) pole. It's true that that could still cause a lot of damage
But I wasn't there, and if someone is facing a baseball bat (and others in the crowd had hammers) to the head then you are right, that is a different ball game to what I was hoping for
Not reliably, which is why every organization that carries and trains with guns trains center of mass shots except for specialized marksmen training for specialized circumstances, who tend to train harder but even more lethal shots.
When you are using a gun, the choices for reliable stopping are nearly identical to those for maximum fatality. If you aren't justified in killing someone, you have no business firing a gun at them, and if you are justified in firing a gun at someone, aiming anywhere in the limbs doesn't make it nonlethal, it just raises the risk to yourself and bystanders by making the outcome less certain.
Were it simple fists I’d wonder what lack of training these officers have. Weapons are another matter.
