The TSA is experimenting with new scanning cameras that can detect concealed explosives on travelers as they walk by. The TSA, along with local law enforcement, is testing the new devices at a busy metro station in Los Angeles and in railway hubs in Washington, D.C.
In a statement, the TSA said the cameras “identify [metallic or non-metallic] objects that block the naturally-occurring emissions emitted by a person’s body.” This triggers an alarm so law enforcement can locate, isolate, and inspect the individual. Devices like this offer a passive security measure, in contrast to the hands-on approach airport travelers know all too well.
“Along with industry partners, we are committed to identifying, testing and deploying technology that addresses threats to transportation across the spectrum,” TSA Administrator David Pekoske said. “We need to innovate and evolve faster than the adversary, and more importantly, deploy technology ahead of the threat-curve.”
Most people likely associate the TSA only with airport security, but the agency also handles security at major ground transportation hubs. As we all saw in New York City recently, these facilities are just as crowded but less-secured than airports,making them appealing to would-be attackers.
That said, technology like this makes perfect sense for use in pre-screening areas of airports as well. Attackers have targeted these areas as well, and for the same reasons as bus and train terminals. Cameras positioned both outside and inside those areas could be effective in pre-empted a devastating attack.
