 New York City subway riders could soon start seeing metal detectors at turnstiles throughout the system. Natalie Migliore reports. Mayor Adams says as soon as the logistics are worked out, the weapon detection technology will be tested out in some subway stations. But do commuters think it's going to work? Probably not, because they get everything through it. They're going to find a way. I don't know how they would implement that. You know, nobody can say if it's going to work or not. They have to try and see. I think that's a good idea.
