One of the great strengths of America is that there are thousands of different municipalities, police departments, and justice systems. A given city can try out a new policy. It works, or even if it doesn't cause a breakdown in society, then it can spread, and all cities benefit. But if works badly, then that city takes the hit, and hopefully everyone else benefits by avoiding that. (The real world is of course messier than that simple model.) It's hard to parse the actual policy change from only mayor's remarks that are quoted in the article. It sounds like it's not heading to law and order policing, but rather trying to hybrid of increased surveillance and faster response times to some kinds of problems. I'm not sure it will work, but either if works or does not, another datapoint will have been explored.
