Protesters heap pressure onto ShotSpotter

Local activists staged a protest demanding that Chicago end its police contracts with the gunshot detection company ShotSpotter.

The rally kicked off at the site where 13-year old Adam Toledo was killed earlier this year by police who were dispatched by a ShotSpotter alert.

Toledo’s killing has brought new scrutiny onto the technology which is now being used by police departments in over a hundred cities in the U.S.
