*April 17, 2012, John Brennan was going through TSA screening at Portland International Airport. With shoes off, no belt, and empty pockets, the business traveler had already gone through a metal detector and a full, invasive pat-down. The residue from the pat-down tested positive for explosives. To prove to the TSA that he was not carrying a bomb, he took off his clothes. For his trouble, his screening was stopped, and he was arrested. Oh, and he missed his flight.
