A bipartisan Senate report blames the Bush administration for the abuse of detainees in Iraq, Afghanistan and Guantanamo Bay, Cuba.
It says the abuse was the direct result of administration detention policies and should not be dismissed as the work of bad guards or interrogators.
The report concludes that harsh interrogation techniques used by the CIA and the U.S. military were directly adapted from the training techniques used to prepare special forces personnel to resist interrogation by enemies that torture and abuse prisoners.
Sen. John McCain, a former prisoner of war, calls the link between the survival training and U.S. interrogations of detainees inexcusable. He says the policies "are wrong and must never be repeated."
A senior aide to former Defense Secretary Donald H. Rumsfeld disputes the report.
