It would not appeal to paranoid fantasists and incompetents like Cheney, but it did the trick in interrogating one key terrorist. From a forthcoming Time piece by Bobby Ghosh:
“The most successful interrogation of an al-Qaeda operative by U.S. officials required no sleep deprivation, no slapping or walling’ and no waterboarding. All it took to soften up Abu Jandal, who had been closer to Osama bin Laden than any other terrorist ever captured, was a handful of sugar-free cookies.”
They're human, remember?
