Shooting someone in the leg/arm doesn't stop them, especially so when other non-lethal means are used too.
To stop someone, you're going to have to exert lethal force in most cases (whether it's lethal or not is beside the point). Body slamming someone is capable of lethal damage on concrete.

Do an experiment. Have a women armed with a cardboard knife with some form of marker on the end, with her intention being to stab you to death. Try and wrestle it from her. I guarantee you'll suffer fatal wounds if she has even the slightest amount of knowledge on where to attack.
Sure, 3 people can body slam 1 person, but you're exposing at least one person other than the knife wielder to lethal injury, in addition to potentially causing lethal injury on the knife wielder anyway (head on pavement = dead).
