Cambridge Brings Back Gunshot Detection After a Deadly Shooting

Lawmakers in Cambridge, Massachusetts, voted to reinstall ShotSpotter after police said the gunshot detection technology could have saved a shooting victim last month. The city had removed the system amid concerns about surveillance and about how often its alerts sent officers to encounters that produced no evidence of gunfire. The reversal is one of the sharper examples of a city rethinking a police-technology rollback after a specific death.
