Only local people should control or change their police but it seems inevitable that in the worst neighborhoods they won’t change their police and they won’t change their own behavior.
It took republicans at the state level to appoint an effective police chief in Detroit and the people love him. He came from outside and wasn’t somebody’s politically connected cousin. Crime rates are falling across the board, response times are down to around 8 minutes from an hour or more. Best of all he’s encouraging people to arm and protect themselves.
It amazes me how many chiefs are against this idea. Americans should be universally armed, IMO.
