TSA justifies pat downs with op-eds — is my paper trail to blame?

TSA recently reduced the number of terrorist warning signs from 94 to 36, but there are still some howlers in the mostly-secret list — including “sweating heavily” (for which TSA offered 63 invalid studies). GAO also scoffed at the notion that TSA agents could detect terrorists by “assessing the way an individual swallows or evaluating the degree to which an individual’s eyes are open.”
