I'll add one I forgot: outlaw any incentives to do "more policing" or more incarceration than nacessary. Fines should never end up in the hands of a local department. Any benefits provided by e.g. private prison companies to local police departments should be investigated as organized crime.
If there is an incentive program doing measurements it must never be measurements of "number of arrests" or similar. It should be measurements of job approval instead.
