A key document released Monday was a long-suppressed CIA inspector-general report on possible detainee abuse. It claims, with only vague details, that in the cases of three of the earliest "high value" Qaeda suspects subjected to CIA questioning, the use of "enhanced" methods got results. For example, the document says that the number of intelligence reports generated from the interrogation of Abu Zubaydah, an early CIA captive, "increased" after the detainee was waterboarded 83 times. But the report doesn't say precisely what information he gave up before or after being harshly interrogated. So, based on this evidence, it is impossible to tell whether waterboarding and other brutal methods really were more effective than nonviolent techniques in extracting credible, useful information from Abu Zubaydah or other detainees....
