Maggie's Farm

I found the portrayal, within the confines of the definition of the formal forms of governance, to be very accurate. You are right that there certainly would not be a monopoly on the rule of law!

The "law" or "police" in an anarchic state would vary greatly from neighborhood to neighborhood. It would be very subjective and have no visible cohesion beyond the distance the bullet in your own personal firearm can travel.

You would have one mercenary force (theoretically hired by an insurance company?) attempting to enforce the seat belt law or speed limits, while the vigilante force in my self-protected sector would prevent you from driving through the 'hood at all.
