An ongoing review shows the U.S. intelligence community has been debunking long-held myths about some of the worst of the worst" at Guantnamo, some of them still held today. The retreat emerges in a series of unclassified prisoner profiles released by the Pentagon in recent years, snapshots of much larger dossiers the public cannot see, prepared for the Periodic Review Board examining the Pentagon's "forever prisoner" population. "It was clear early on that the intelligence was grossly wrong," said Mark Fallon, a retired 30-year federal officer who between 2002 and 2004 was Special Agent in Charge of the Department of Defense's Criminal Investigation Task Force. Most "weren't battlefield captives," he said, calling many "bounty babies" - men captured by Afghan warlords or Pakistani security forces and sent to Guantnamo "on the sketchiest bit of intelligence with nothing to corroborate." They ended up with "a lot of false information based on some pretty poor interrogations being done partly by military interrogators in that time frame." Fallon ... is in the final stages of publishing a book of his criticisms and said in a recent interview that it's no surprise that early prisoner profiles are imploding under Periodic Review Board scrutiny. In the early years, according to one analyst who worked there, Guantnamo's Joint Intelligence Group was "looking for anything you can pin on these guys." The intelligence unit was "picking up on one or two things and holding on to it tightly like it was gospel."
