"Police" comes from the word "policy". The so called police are merely municipal policy enforcement officers. So the question is EXACTLY what municipal policies apply to private people? The answer for the most part is none. Because in America the rules, regulations, codes etc ONLY apply to the office holders - they being the "public" (a "public school is a government school, a CPA is certified governemnt accountant etc).
Unfortunately most of the sheeple beLIEve all that nonsense applies to them.
