Bin Laden's Death Revives Debate Over Interrogation

U.S. officials say Osama bin Laden was found by tracking his most trusted courier. Knowledge about that courier was gleaned in part through the interrogation of detainees, either at Guantanamo or in CIA prisons. Supporters of the Bush administration's detention policies say the bin Laden operation demonstrated that "enhanced interrogation" tactics actually worked to provide valuable information. Some intelligence officials say that argument is too simplistic.
