But in all truth, you can aim for the hands and feet. Are they smaller targets? Yes it is harder. Are they moving targets? Only if they're in motion. If they're standing still and pointing a gun then no, they are not moving (And again I only suggest using lethal rounds to target the hands and feet- I suggest headshots with rubber bullets). Rubber bullets are not only used for training purposes, actually. They are used for situations specifically like the one mentioned in the OP's original post. They are also used for riot control in some regions. Obviously the military doesn't use them, but police officers in the real world most certainly do (Honest, bro- I'm not lying).
I'd also like to see someone continue to fight after being shot in the face with a less-lethal round. They're going to be knocked unconscious at the very least, but there's still a good chance it might kill them too. CB JONES's opinion that lethal rounds are better is in fact just that, an opinion. It's not necessarily true. Just like your opinion that you can't aim for hands and feet. That's not true either. DELTA and SAS snipers are trained to aim for lethal killzone target areas on the body. But they are also trained to target less vital areas in case there's a bomb threat or hostage situation. In a world of terrorism and technology, it may be necessary to preserve the life of a man with explosives strapped to his own body. Interrogation is part of the job. He's not afraid of being hit with lethal bullets. He's a suicide bomber with valuable information who's already willing to die. There must be another way. You can't just go around killing bad guys anymore. It's important to think about these things in our everyday life.
