After mass shooting, NYC explores gun detectors in subways

NEW YORK (AP) — In the aftermath of a mass shooting on a New York City subway train, the mayor floated a high-tech idea: deploy scanners that can spot someone carrying a gun into the transit system before they have a chance to use it.

The technology to scan large numbers of people quickly for weapons does exist, and is used now to screen people at places like sports stadiums and theme parks.

But security experts say installing such a system in the city’s sprawling, porous subway system in a way that would make a difference would be difficult, if not impossible.

The problem wouldn’t necessarily be the technology — but rather the reality that scanners need to be accompanied by human operators to confront people carrying firearms illegally.
