Better policies will need to change police culture - next to impossible. People are not fleeing states due to fewer police, and probably not due to the increases in robbery. Economic reasons are far more motivating. Fact is the only real increases in crime are in the poor neighborhoods and they can't "flee."
Any cut in police is due to tax revenue problems, which are solely economic and that has two effects, it makes people more likely to commit robbery (which is where the increase is), and to move somewhere else. Fewer police have nothing to do with anything. They always say crime is related to police to get more funding. Apparently the police-surveillance state has no effect on crime.
Crime is their cover story. What they're really for is to control and coerce and intimidate the People (primarily non-whites, but whites too). If you understand what's happening you will realize we are being prepared for global totalitarianism, which means total control, no freedom at all. Just wait until central bank digital currency arrives, which is on it's way:

Won't be any crime then.
