TSA Adopts Behavior Screening To Speed Security Lines
But the GAO questions whether the technique has any validity
The Transportation Security Administration is taking another step back from its one-size-fits-all security screening that requires all airline passengers to remove their belts, shoes and coats at checkpoints.
The agency already makes some exceptions, including allowing some frequent travelers who have passed background checks to move more quickly through security — an E-ZPass, of sorts, called PreCheck for passengers traveling in the United States.
Now, the agency is testing a new behavior detection program where officers use on-the-spot observations and conversations with passengers to select some for the quicker pass through the checkpoint.
