The idea that police should be conscripted is crazy when you consider that the vast majority of the population just doesn't have the nerves to stop that person in the sketchy car or dark side of the sidewalk, knowing there's a probability they will try to murder you, whether because they hate cops or to avoid arrest, while yourself carrying a lethal weapon. (A lot of police don't even have the nerves for it.) More innocent people would get shot, without question.
