The LA Times reports that Khalid Shaikh Mohammed has told "U.S. military officials that he gave false information to the CIA even after undergoing punishing bouts of interrogation."
Expect liberal commentators to underscore the fact that not only is torture un-American, it is also unreliable. And be sure that conservative commentators will say that the liberal media, in their frenzy to bash everything American, are ready to believe a terrorist who has an obvious motive in lying.
But don't let the spin make you lose sight of the facts: it is only civilians like Cheney, his daughter, Bush, etc., who maintain that torture works and that it has prevented further attacks on the United States. Conversely, there is no scarcity of people in the law and order and the military communities who will readily tell you that torture does not work, and why.
See here, here, here, here, and... well, you get the idea.
We did not really need KSM, as Bush affectionately called Khalid Shaikh Mohammed in press conferences, to tell us what everyone in the interrogation business already knew: Bush, Cheney, father and daughter, and all their truly despicable minions, however well intentioned they thought they were, have subverted the Constitution, international conventions, and American decency for... absolutely nothing.
