WTF did they think this would accomplish?

Khalid Sheikh Mohammed was waterboarded 183 times in one month.

Marcy Wheeler digs through the recently-disclosed Office of Legal Counsel memos authored by the Bush Justice Department and finds these startling statistics: Khalid Sheikh Mohammed was waterboarded 183 times in March 2003 and Abu Zubaydah was waterboarded 83 times in August 2002. Wheeler concludes, “The CIA wants you to believe waterboarding is effective. Yet somehow, it took them 183 applications of the waterboard in a one month period to get what they claimed was cooperation out of KSM. That doesn’t sound very effective to me.”
