1. Disband all municipal and county police / sheriffs.
2. Create county / municipal level traffic enforcement units that do not have arrest powers, like a meter maid that can pull you over and issue a citation for a traffic offense but nothing else.
3. Move former detectives / investigators under the supervision of the prosecuting attorney.
4. Create county level, community oriented crime reporting precincts where folks can come to report non-emergency crimes that are then forwarded to the prosecuting attorneys office for investigation.
5. Create county level, community oriented first responders (what we would see today as a typical cop or deputy) that ONLY respond to in-progress calls and take no enforcement action outside of those calls for service. When not responding to emergency calls, their job is entirely to engage with the community they serve. They are to take NO enforcement action outside of those calls for service. This agency would have total civilian oversight.
6. All narcotics investigations / search warrants are to be handled by state level investigators that are well trained and supervised - no more local and county level yahoos kicking in doors over a joint.
By breaking up and delegating the duties assigned to police departments, we drastically reduce the us vs them mindset that has perverted police departments across the country. Community oriented law enforcers with civilian oversight who take no enforcement action when not called for service would encourage crime victims to report crime and law enforcement would be seen as as an ally and not an enemy.
