I wonder from time to time, but in these government-less systems, who handles police?
Obviously, the current police system is absolute shit and horrible. But bad people can exist even in an environment where everyone's basic needs are met. Most people are good and most who commit crime today do so as a direct result of their terrible environment, upbringing and/or "the system" failed them (e.g. unable to get mental health help because profits)
But what do you do about those who do terrible shit for no other reason than "because they could"?
