Transcript for TSA tests technology to prevent suicide bombings in mass transit areas
The Transportation Security Administration. Is testing technology that could one day stop the next suicide bomber from entering a busy rail hub like this. This technology has been used at the Super Bowl it has been used for a papal visit here in New York. But it is never been deployed by transit systems and so the TSA. Working with a Amtrak police. Trying to decide if this would be a good way to detect someone nefarious who wants to do harm. In the rail station and here's how it works do you see anybody coming down the stairs. It appears. Like a green block green is good. If someone had something strapped to them that could be potentially harmful. Well that would appear to be read or would appear to be a black box. And if the TSA machine detected it. Amtrak police could then intervene send a K nine unit or some officer. To try and stop that individual before that person penetrates deeper into the station. This one. To me looks more like a spotlight mounted on a tripod but it's the same kind of a thing a scanner. That has its lenses trained on the staircase. Or the escalator right here independent station. Anything detects something. Is wrong. It would show up on the screen you can see. A passenger coming down the steps and it's an ordinary green bar green is good and so there is nothing to worry about what this particular passenger. But if you take a look at someone else who might have something strapped to them well then. That person. Would show up as red and again a police officer could intervene. The Transportation Security Administration would not buy these things it would be up to the individual mass transit systems to buy them. If it works this technology could be deployed in this rail hub and others by the end of the year. And perhaps it could be used nationwide.
