This is an almost unbelievable account of a young man being held extra-legally for the crime of flying alone while brown during a religious holiday and deviating ever-so-slightly from the herd (ie, "opting out" of the naked scanner). It it's unclear which aspect(s) of his transgression played the biggest role in his 4 hour interrogation by no fewer than 4 different government bureaucracies and as well as an airline.
Obviously, if you have nothing to hide (which apparently now includes your medical history) you still have much to fear, particularly at an airport.
