Survivors of CIA torture have sued the contractor psychologists who designed one of the most infamous programs of the post-9/11 era. In an extraordinary step, psychologists James Mitchell and Bruce Jessen now face a federal lawsuit for their role in convincing the CIA to subject terror suspects to mock drowning, painful bodily contortions, sleep and dietary deprivation and other methods long rejected by much of the world as torture. In practice, CIA torture meant disappearances, mock executions, anal penetration ... and at least one man who froze to death, according to a landmark Senate report last year. On behalf of torture survivors ... as well as a representative of the estate of Gul Rahman - who froze to death in a CIA black site in Afghanistan - the American Civil Liberties Union (ACLU) filed the suit against Mitchell and Jessen on Tuesday in a federal court in Washington state. The suit calls the torture program a "joint criminal enterprise" and a "war crime" in which the CIA, Mitchell and Jessen colluded and from which Mitchell and Jessen financially profited. Although numerous US government investigations have pierced the veneer of secrecy around the torture program, the program's government architects have faced no legal reprisal. A Justice Department inquiry ended in 2012 without prosecutions. The new lawsuit, aimed not at government officials but the contractors Mitchell and Jessen, aims to break the trend.
