Northeastern city votes to end ShotSpotter contract for gunfire-detection tech designed to fight crime

Cambridge, Massachusetts voted to end its contract with ShotSpotter, a gunshot detection system used by police, citing concerns about reliability, false positives, and potential links to federal immigration enforcement. The decision follows similar action by Chicago in February 2024 and reflects growing skepticism about the technology among some cities. The city has 90 days to discontinue use and remove the acoustic sensors from neighborhoods.
