The line from Bush to Abu Ghraib...

... has never been clearer, according to the new Senate Armed Services Committee Inquiry Into The Treatment of Detainees in U.S. Custody:

Conclusion 1: On February 7, 2002, President George W. Bush made a written determination that Common Article 3 of the Geneva Conventions, which would have afforded minimum standards for humane treatment, did not apply to al Qaeda or Taliban detainees. Following the President’s determination, techniques such as waterboarding, nudity, and stress positions, used in SERE training to simulate tactics used by enemies that refuse to follow the Geneva Conventions, were authorized for use in interrogations of detainees in U.S. custody.

Conclusion 2: Members of the President’s Cabinet and other senior officials participated in meetings inside the White House in 2002 and 2003 where specific interrogation techniques were discussed. National Security Council Principals reviewed the CIA’s interrogation program during that period.

Conclusion 13: Secretary of Defense Donald Rumsfeld’s authorization of aggressive interrogation techniques for use at Guantanamo Bay was a direct cause of detainee abuse there. Secretary Rumsfeld’s December 2, 2002 approval of Mr. Haynes’s recommendation that most of the techniques contained in GTMO’s October 11, 2002 request be authorized, influenced and contributed to the use of abusive techniques, including military working dogs, forced nudity, and stress positions, in Afghanistan and Iraq.

Conclusion 19: The abuse of detainees at Abu Ghraib in late 2003 was not simply the result of a few soldiers acting on their own. Interrogation techniques such as stripping detainees of their clothes, placing them in stress positions, and using military working dogs to intimidate them appeared in Iraq only after they had been approved for use in Afghanistan and at GTMO. Secretary of Defense Donald Rumsfeld’s December 2, 2002 authorization of aggressive interrogation techniques and subsequent interrogation policies and plans approved by senior military and civilian officials conveyed the message that physical pressures and degradation were appropriate treatment for detainees in U.S. military custody. What followed was an erosion in standards dictating that detainees be treated humanely.
