> How are you going to get anyone to become a policeman?
Ideally, you aren't; you are going to disband the centralized, omnipurpose paramilitary law enforcement entities known as "police departments", redistribute law enforcement responsibilities among domain-specific entities that for the most part are not exclusively, or even centrally, law enforcement, and not violate the public trust the way police departments have broadly and systematically done over an extended period of time.
