"The very idea that calling some "special" person to your aid from somewhere far away, necessitating his driving at nearly (or sometimes actually) reckless speeds, forcing traffic off the road, to save you from a threat that you and those in your immediate presence could just as easily defend yourselves from with only a modicum of training is insane. Having "police" everywhere and nowhere within a community, leaving criminals without the means to determine just who will use force to stop him is a real deterrent to crime." https://www.quora.com/To-what-extent-do-police-prevent-crime
