Admit only minority people into the Police force. Problem solved. If a Policeman kills minority unlawfully then it's just minority on minority crime so nobody will care.
Half the officers charged over Freddie Gray's death were black. No one was less mad over it because of that.
The system can be racist even if its constituents aren't. It shouldn't be a new or unfamiliar idea to anyone here that complex systems can have unexpected outcomes, biases, and emergent properties.
Some of the worst police departments are majority minority with minority leadership all the way up to the mayor's office. This is obviously not a solution

That's the data, not my opinion.
