2. Bring back sheriff;s instead of having police forces report to a mayor or other executives, the head of the police force should be an elected position accountable to the people
3. Expand open records laws to include policy manuals for every police force, and create a Citizen Review Board that can have no more than 1 retired or former police officer, judge or prosecutor on it. Today many "Citizen" review boards are filled with insiders of the force, retired cops, family members, prosecutors,etc
4. Mandatory body camera's for all public interactions with at most a 3 strike policy where if the officer fails to record an interaction more than 3 times they are terminated
5. End Qualified immunity
That’s why the constitution is all about limiting the role of government.
A Really Basic police reform step might be to institute minimum standards for hiring police. And assign the "background checks" job to a carefully monitored central specialty office.
