Q: Why would private police forces be better than a monopoly police force?
A: A private police force is better than a public police force because if it does a bad job, you can fire them tomorrow and hire another one, just as you can fire Brinks Home Security and hire Guardian Protective Services, tomorrow, without asking permission of anybody. Your neighbor’s don’t have to agree with you. They can continue to use whatever service they use now. But if you turn out to be happier with Guardian than with Brinks, you can also let your neighbors know that they provide a better value for the money.
A public police force always ends up doing things you don’t want done. They shoot unarmed people in the streets, especially minorities. They arrest more people for smoking weed in America than for all violent crimes combined. Including the government as a whole, they murder people abroad on flimsy pretexts to make money for Big Oil. These are services that no sane person wants. But because they are “public”, they are permitted to force you at gunpoint to buy their service, even if you want nothing in the world more than to be free of it. That makes it, not a Protective Service, but a Protection Racket. They promise to protect you if you buy their service. They promise to harm you themselves if you don’t buy their service. That’s exactly what the mafia does. Except that the Mafia doesn’t have little nannies who follow you around after they extort you telling you what to do. They are not that presumptuous.
Ferguson, MO, for example, might want to get the New Black Panthers or the Huey Newton Gun Club to patrol their streets, instead of their current racist, violent, murderous police force. It would probably be much safer to be black in Ferguson if they did so.
