"What the US official didnt say was that the Feds often and purposely exclude terrorists from such lists. Joe Trento is an investigative journalist and the author of Unsafe at Any Altitude: Failed Terrorism Investigations, Scapegoating 9/11, and the Shocking Truth about Aviation Security Today. He reports, "At the Central Intelligence Agency and Defense Intelligence Agency certain names and aliases are kept from the airlines and off the no-fly list to protect intelligence assets who are suspected or known terrorists." Why? Because, as Mr. Trento explains in his book, "...American intelligence and counterterrorism officials ... deliberately [allow] suspected terrorist to fly among innocent passengers in the hope that a terrorist would lead them to collaborators or even a terrorist cell." The government that nicks your Neutrogena lest you blow up your flight merely winks at Terry Q. Terrorists boarding." .
