No, no, no.
I can think of exactly *one* case where shooting by a cop was meant to do anything other than to kill. And it was a guy with a gun, sitting in a chair in public. And the cop was a military-trained marksman, using a sniper rifle from a rooftop. And this was considered high-risk. Far more common are stories where cops shoot at someone, and hit a bystander.
Two basic rules:
1) if you shoot to "disable", and the person is not disabled, then you now have a very angry person with a weapon, who will consider you to be a deadly threat, and correctly so.
2) a so-called "disabling shot" is very likely to kill the person who was shot. If you paralyze someone, you've likely hit something very important. A "disarming shot" at someone, with a relatively low-accuracy weapon like any handgun, at a fleeing person, is Calamity Jane - level marksmanship at the very least, and actually, I don't recall even her pulling that off.
"Shoot at center mass." is probably Rule #3 for general handgun training, right behind "Always treat a gun as if it's loaded." and "Never point a gun at anyone you don't intend to kill." Again, shooting at someone with a handgun is deadly force, always. And the majority of cops only have the most basic training, because most cops never pull out their guns in the line of duty.
