First, it seems that police are too quick to pull a gun and shoot people. Second, it seems that there are still plenty of examples where police having guns saves lives (mass shootings and the like). I have noticed that police seem to do most of their killing with a pistol, a weapon they have available at all times, no matter what. Perhaps, instead of giving cops pistols, we should only give them AR-15s. This gives them a viable (superior) option during actual gunfights, mass shootings, and so forth, but also takes away the option of impulsively shooting people or simply wandering foolishly into a situation and escalating it till they kill someone. The AR-15 is too unwieldy to carry around, but can be locked in a car until it is needed.
