Living in a country with an inefficient police department is not fun. Ask anyone from you know who came from Cuba, Brazil, Honduras, Venezuela, or South Africa.

Living in a country with an extremely efficient police department is not fun either. See: China and Singapore.

There is a balance. Banning soulless social credit-tier stuff like this is a good step in the right direction. Another problem with stuff like "predictive policing" is that everyone knows a hypothetical 100% enforcement of the law would put almost everybody in prison; there are too many laws on the books in the USA. The first laws that come to mind are about the drug war. (Even cops are drug (steroid) addicts, so they themselves would go to prison too under 100% enforcement.) I don't use drugs, not even alcohol, but if someone thinks some white powder is going to make them happy or selling it would put food on the table then they should not be brutalized by the state for it.

ML and mass surveillance is going to actually allow 100% enforcement of laws, so it's time to have this discussion and redo the criminal code.
