My brother and two cousins are cops in different cities in different states (PA and OH).
Seemingly their training is very similar and its only certain laws and regulations that are different.
It hard for cops to injure and not kill when shooting someone. They would have to be very accurate. Hence they all teach the two to the body one to the head thing.
In saying that they are all issued less lethal weapons for someone coming at them with knifes etc... they have tasers and are trained in hand to hand combat with the police stick.
My brother once told me that in an instant given how they are trained to pull their gun then that's what they do. Most don't consider pulling a taser when they see a weapon like a rock, metal bar or a knife.
Its a tough job and honestly they could do with retraining on how to start out pulling a less lethal weapon until they see a gun. This mentality that they have no time seems to be an excuse. This is where myself and my brother disagree. Although I suspect he would never admit he could easily pull another weapon and change it quickly if needed.
