I think there needs to be an option to refuse certain public services, namely police action, in any neighborhood or district that deems such service unwelcome.
That means black neighborhoods. I think it would be a good idea for black people to be able to say they did not want any police activity in their area.
As a proof on concept, I'd point to Baltimore.
Baltimore is a rousing success. Far less government spending is being wasted trying to enforce law and order on savages that appreciate neither, and more savages are naturally selecting themselves right out of existence. Win/win.
Also, bulletproof glass IS racist in black neighborhoods and needs to be removed from all businesses. Oh yes, there will be blood.
