But the JPRA's two-page attachment, titled "Operational Issues Pertaining to the Use of Physical/Psychological Coercion in Interrogation," questioned the effectiveness of employing extreme duress to gain intelligence.

"The requirement to obtain information from an uncooperative source as quickly as possible -- in time to prevent, for example, an impending terrorist attack that could result in loss of life -- has been forwarded as a compelling argument for the use of torture," the document said. "In essence, physical and/or psychological duress are viewed as an alternative to the more time-consuming conventional interrogation process. The error inherent in this line of thinking is the assumption that, through torture, the interrogator can extract reliable and accurate information. History and a consideration of human behavior would appear to refute this assumption."
