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.
