"It was apparently here, just under an hour's drive from Szymany airport, that Sheikh Mohammed was tortured, exactly 183 times with waterboarding -- an interrogation technique that simulates the sensation of drowning -- in March, 2003 alone. That averages out to eight times a day. And all of this happened right here in Europe."

Anyone with half a brain would see the implications of this statement, assuming it's correct: either waterboarding isn't effective as an interrogation technique, or the intent was never to obtain information. Since KSM "confessed" to everything from the assassination of Alexander Hamilton (from the grassy knoll) to the downing of American Airlines Flight 587 (accidental), it's safe to say that one of its purposes was to manufacture false confessions.
