Why they want to use torture

According to the sources, CIA officers who subjected themselves to the water boarding technique lasted an average of 14 seconds before caving in. They said al Qaeda's toughest prisoner, Khalid Sheik Mohammed, won the admiration of interrogators when he was able to last between two and two-and-a-half minutes before begging to confess.

"The person believes they are being killed, and as such, it really amounts to a mock execution, which is illegal under international law," said John Sifton of Human Rights Watch.

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.

Ah,but there was a reason why they wanted that particular answer.They used the "techiques" to get the desired result so they can use the info to justify the war. Nice and neat, wasn't it?
