What they want is a federal police force. This "defund" crap is just there to justify consolidation of power.
Constitutionally speaking, city police SHOULD be disbanded and re-allocated into county Sheriffs. Sheriffs are elected. Sheriffs are accountable. City police corruption exists because Police Chiefs are appointed by the system.
It’s probably simpler to mandate that City Police Chiefs must be elected. Rather then appointed by the Mayor.
Saves time and money in the long run, as you don’t need to undergo costly reorganizations, and satisfies the accountability via elections desire you have.
But being elected doesn’t equal accountability nor stop corruption. Lord knows enough Elected Officials including Sheriffs are bought and paid for by one person or another.
