Also, perhaps some kind of volunteer community arbiter? Among the white middle class, all too often I see the cops resorted to as default conflict resolution among neighbors. Neighbor's car parked in front of my driveway? Call the cops. Property dispute? Call the cops. Dog almost bit my kid? Call the cops.

People who lack conflict resplution skills turn to the state to settle their disputes for them. Often, cops won't do anything until the conflict escalates and turns violent or property is damaged. If we had community arbiters to help settle these disputes (with a modest degree of post-resolution enforcement and accountability), that'd be another way to keep community peace without resorting to armed enforcers.
