They just can't seem to get their stories straight. No matter how hard they try to justify torture, the facts don't seem to support them:

WASHINGTON — The CIA inspector general in 2004 found that there was no conclusive proof that waterboarding or other harsh interrogation techniques helped the Bush administration thwart any "specific imminent attacks," according to recently declassified Justice Department memos.

That undercuts assertions by former vice president Dick Cheney and other former Bush administration officials that the use of harsh interrogation tactics including waterboarding, which is widely considered torture, was justified because it headed off terrorist attacks.

[...] "It is difficult to quantify with confidence and precision the effectiveness of the program," Steven G. Bradbury, then the Justice Department's principal deputy assistant attorney general, wrote in a May 30, 2005, memo to CIA General Counsel John Rizzo, one of four released last week by the Obama administration.

"As the IG Report notes, it is difficult to determine conclusively whether interrogations provided information critical to interdicting specific imminent attacks. And because the CIA has used enhanced techniques sparingly, 'there is limited data on which to assess their individual effectiveness'," Bradbury wrote, quoting the IG report.

Nevertheless, Bradbury concluded in his May 2005 memos that the program had been effective; that conclusion relied largely on memos written after the still secret report by Inspector General John Helgerson.

Helgerson also concluded that waterboarding was riskier than officials claimed and reported that the CIA's Office of Medical Services thought that the risk to the health of some prisoners outweighed any potential intelligence benefit, according to the memos.

The IG's report is among several indications that the Bush administration's use of abusive interrogation methods was less productive than some former administration officials have claimed.
