Most police do not use hollow point, simply because they are better trained than a civilian, and hit what they aim at, if they did use them they would end up in court not the person they shot.
The problem I have with civilian use is simple, they just shoot in the general direction of the perceived threat, and don't have the training required to hit first time, several shots are fired, what happens if you miss and hit a 5 year old, what then, say your sorry ? at least with a metal jacket round the kid might have a chance to live.
