...the report describes how one detainee, suspected USS Cole bomber Abd al-Rahim al-Nashiri, was threatened with a gun and a power drill during the course of CIA interrogation. According to the sources, who like others quoted in this article asked not to be named while discussing sensitive information, Nashiri's interrogators brandished the gun in an effort to convince him that he was going to be shot. Interrogators also turned on a power drill and held it near him. "The purpose was to scare him into giving [information] up," said one of the sources. A federal law banning the use of torture expressly forbids threatening a detainee with "imminent death."
And in a clear case of "see we did nothing wrong, you can't prove it..."
Before leaving office, Bush administration officials confirmed that Nashiri was one of three CIA detainees subjected to waterboarding. They also acknowledged that Nashiri was one of two Al Qaeda detainees whose detentions and interrogations were documented at length in CIA videotapes. But senior officials of the agency's undercover operations branch, the National Clandestine Service, ordered that the tapes be destroyed, an action that has been under investigation for more than a year by a federal prosecutor.
