The only “benefits” to local police are faster response times in emergencies and the ability to enforce nuisance ordinances. The former is not something you want from Bill’s Drinking Buddies and the latter would be better handled by county workers anyway.
Generally speaking: The vast majority of what cops do would be better handled by social workers and bureaucrats with a clipboard. And it reduces the likelihood of a noise complaint resulting in the ritualistic sodomy and execution of a dog and its owners.
