For the first time, a federal judge is letting a civil lawsuit proceed against two CIA contract psychologists who designed and supervised brutal interrogation tactics that critics called torture. The ruling allows two former CIA detainees and the family of another who died in agency custody to try to win damages in federal court for the abuse they suffered at then-secret CIA prisons in the early 2000s. According to the lawsuit and a Senate Intelligence Committee report, the mistreatment included waterboarding, sleep deprivation, confinement in small boxes, rectal feeding and beatings. As the lawsuit progresses, it may shed more light on the so-called enhanced interrogation techniques that the CIA used in an effort to collect intelligence ... after the Sept. 11, 2001, attacks. It's unprecedented," [said] Dror Ladin, the American Civil Liberties Union attorney who argued the plaintiffs' case in court. "No CIA torture victim has ever taken this step toward accountability. Every previous lawsuit has been shut down before this stage. "It gives our clients a chance to ... finally get some justice," he said. The Department of Justice had blocked previous lawsuits aimed at the CIA's now-barred detention and interrogation program on grounds that any case could reveal secrets and compromise national security. That changed after the Senate Intelligence Committee released a report in December 2014 that exposed details about the program, including the role played by [psychologists Bruce] Jessen and [James E.] Mitchell.
