If you want to lessen or eliminate the politics in policing, then make Police Chiefs elected officials. The systemic/underlying problem of racism and problematic police policies can be directly addressed if the Police Chiefs were elected officials. Police Chiefs should be elected officials, never appointees. When Mayors appoint Police Chiefs, the Police Phief becomes a political tool of the Mayor. Proof of this is when the Mayor orders the Police Chief to pull officers from areas to prevent use of force during riots and unrest, when use of force is likely. Police Chiefs who are elected would not back down to protect their citizens even when under scrutiny.
