After being shot? Or being shot once? All the videos you linked; the bad guy gets dropped (I couldn't load the 1st one so I didn't see it).
They all took multiple rounds, except for the guy that takes off, gets rammed, and comes out shooting. He takes one, I think to the head, and drops on the hood then they continue to shoot. I'd have pumped a few more into him to make sure he wasn't moving too!
Shot placement is key and normally cops don't train using stress shooting so when they get in shoot outs, they usually never hit vital areas that incapacitate their targets. They are usually the ones that talk about one shot stops, caliber being the holy grail of gun fighting.
I say shot placement, whether .22 on up to 120mm smooth bore! Hit the right spot and you don't have to worry about follow up shots.
Horse shoes, hand grenades, and on up to 2000lbs JDAMs ----- close is ok.
