A pilot program testing AI-powered weapons scanners inside some New York City subway stations this summer did not detect any passengers with firearms — but falsely alerted more than 100 times.

The city’s new gun-detecting scanners set up at some subway stations produced false positives on over 4% of scans, according to the NYPD. The city tested the machines, which look like traditional metal detectors,

A 30-day pilot program of using scanners to detect weapons in the subway is over. According to the NYPD, some 2,749 scans done during the pilot program. There were 118 false positives, the NYPD said.

NYPD officials said late Wednesday that the controversial Evolv weapons scanners Mayor Adams’ administration rolled out in the city subway system detected 12 knives and no guns over the

The NYPD said Thursday that the month-long gun detector pilot yielded 12 knives, 118 false positives, and zero firearms. City Limits’ CLARIFY youth journalists spoke to transit riders and advocates to get their thoughts on the use of weapon scanners in the system.

The controversial pilot of Evolv’s gun scanners in subway stations ended in August, and Mayor Eric Adams has said the department will tell us how it went. But when?
