Apparently that wasn't really a bug, but a feature. The Times also recently pointed that even though the Bush administration was warned that one of the information sources, al Libi, was full of shit they kept on using his information to justify the war.
The Times article quoted a Defense Intelligence Report claiming that al-Libi "was intentionally misleading the debriefers" although this stretches the concept of "intentionally" somewhat.
You see, al-Libi was a fine graduate of our exciting new school of interrogation. On him we used torture techniques designed to encourage the subject to tell the interrogaters what they wanted to hear. And, miracle of miracles, he did indeed tell them what they wanted to hear.
However, ABC News was told that at least three CIA officers declined to be trained in the techniques before a cadre of 14 were selected to use them on a dozen top al Qaeda suspects in order to obtain critical information. In at least one instance, ABC News was told that the techniques led to questionable information aimed at pleasing the interrogators and that this information had a significant impact on U.S. actions in Iraq.
According to CIA sources, Ibn al Shaykh al Libbi, after two weeks of enhanced interrogation, made statements that were designed to tell the interrogators what they wanted to hear. Sources say Al Libbi had been subjected to each of the progressively harsher techniques in turn and finally broke after being water boarded and then left to stand naked in his cold cell overnight where he was doused with cold water at regular intervals.
His statements became part of the basis for the Bush administration claims that Iraq trained al Qaeda members to use biochemical weapons. Sources tell ABC that it was later established that al Libbi had no knowledge of such training or weapons and fabricated the statements because he was terrified of further harsh treatment.
"This is the problem with using the waterboard. They get so desperate that they begin telling you what they think you want to hear," one source said.
However, sources said, al Libbi does not appear to have sought to intentionally misinform investigators, as at least one account has stated. The distinction in this murky world is nonetheless an important one. Al Libbi sought to please his investigators, not lead them down a false path, two sources with firsthand knowledge of the statements said.
Just to recap. Bush administration needs evidence to support their war. They use torture techniqes designed to extract false confessions to obtain that "evidence," which they then use to sell the war despite knowing full well of the lack of reliability of the information.
