Waterboarding worked. According to the CIA the technique helped thwart a planned 9/11 style attack on Los Angeles. People are free to quibble about the morality of using enhanced interrogation. People can debate if the terrorists are entitled to any protections at all, and if that should even matter. You can even talk about if instead of interrogating people we just handed them a wad of cash and sent them on their way, would they would stop sawing the heads off of their prisoners. The effectiveness of enhanced interrogations however seems no longer up for debate as the CIA is confirming that it does work, and well at that.
"Before he was waterboarded, when KSM was asked about planned attacks on the United States, he ominously told his CIA interrogators, “Soon, you will know.”
According to the previously classified May 30, 2005 Justice Department memo that was released by President Barack Obama last week, the thwarted attack -- which KSM called the “Second Wave”-- planned “ ‘to use East Asian operatives to crash a hijacked airliner into’ a building in Los Angeles.”
Indeed, before the CIA used enhanced techniques in its interrogation of KSM, KSM resisted giving any answers to questions about future attacks, simply noting, ‘Soon you will know.’”
After he was subjected to the “waterboard” technique, KSM became cooperative, providing intelligence that led to the capture of key al Qaeda allies and, eventually, the closing down of an East Asian terrorist cell that had been tasked with carrying out the 9/11-style attack on Los Angeles."
