Photos: These 'Gun Detectors' Could Come To NYC Subways

NEW YORK, NY — Mayor Eric Adams' push for metal detection technology on the city's subways is evolving closer to reality.

The mayor set up weapons-detection systems from Evolv Technology at City Hall this week in a first swing at testing which devices can weed out guns from the city's subway system.

"We're seeing how it operates," said the mayor, who has been urging metal detection on the transit system in the wake of the Brooklyn mass shooting that left 23 people injured.

The Evolv systems, which have also been floated for New York City's public schools, are touted as a new kind of sensor that can detect weapons without the hassle of manual bag checks or security wands, according to their website.

At City Hall, crowds were ushered through the systems without taking anything out of their pockets or bags (though the traditional security checkpoint was still set up behind the devices).

The push for weapons detection comes as Adams — a fan of unique crime-fighting technology — grapples with a spike in gun violence that has not spared the city's subways. Aside from the Sunset Park attack, at least two people have been shot inside the transit system in the last two months, one of whom died.

"They detect guns ... we’re going after guns," Adams said of the Evolv systems Wednesday.

But the potential sensors aren't without their flaws, according to reports. When used elsewhere in the country, the Evolv systems had difficulty distinguishing between weapons threats and likely a common item on the subway — Chromebooks.

Even if the sensors’ problems are ironed out, the mayor will have to convince the state-run MTA, which controls the subway system, that they are worth adding.

Adams said Wednesday subway safety technology was among many items he pitched during a visit with state lawmakers this week.

The mayor also noted that other forms of technology are still in the conversation.

"We're going to try all new forms of technology," Adams said. "There are other products we want to continue to look at."
