The new mayor of New York City has a plan to reduce gun crime. I can imagine that "targeted, precision policing" of 30 precincts is (1) not very different from "predictive policing" and (2) not a big change from what's already done.

I can also imagine that "spot checks" and bus and train stations will not be very different from "stop and search", and that most of the arrests they make will be for drug possession. Though they may succeed in dissuading non-car-owners from New Jersey to come into New York City with weapons.

What other things will the reported "new technology" do, besides identify people with illegal guns?'
