NEW YORK (AP) — A gunfire location and detection system long used by the New York Police Department and other law enforcement agencies nationwide is sending police officers to respond to loud noises that don’t turn out to be confirmed shootings 87 percent of the time, a city audit released Thursday has found.

The low rate of confirmed shootings through ShotSpotter means police officers spent thousands of working hours responding to unfounded reports of gunfire, said New York City Comptroller Brad Lander, whose office conducted the audit.
