Not only is torture wrong, it doesn't work. You cannot get reliable information from someone who will say anything to save his own life.
Case in point: "Arar, now 36, was detained by U.S. authorities as he changed planes in New York on Sept. 26, 2002. He was held for questioning for 12 days, then flown by jet to Jordan and driven to Syria. He was beaten, forced to confess to having trained in Afghanistan -- where he never has been -- and then kept in a coffin-size dungeon for 10 months before he was released, the Canadian inquiry commission found."
And furthermore, I wonder if the Syrain goons Bush paid to torture this innocent Canadian ever crossed paths with Gilad Shalit, Ehud Goldwasser and Eldad Regev.
