When Justice Department lawyers engaged in a sharp internal debate in 2005 over brutal interrogation techniques, even some who believed that using tough tactics was a serious mistake agreed on a basic point: the methods themselves were legal.
Previously undisclosed Justice Department e-mail messages, interviews and newly declassified documents show that some of the lawyers, including James B. Comey, the deputy attorney general who argued repeatedly that the United States would regret using harsh methods, went along with a 2005 legal opinion asserting that the techniques used by the Central Intelligence Agency were lawful.
That opinion, giving the green light for the C.I.A. to use all 13 methods in interrogating terrorism suspects, including waterboarding and up to 180 hours of sleep deprivation, “was ready to go out and I concurred,” Mr. Comey wrote to a colleague in an April 27, 2005, e-mail message obtained by The New York Times.

While signing off on the techniques, Mr. Comey in his e-mail provided a firsthand account of how he tried unsuccessfully to discourage use of the practices. He made a last-ditch effort to derail the interrogation program, urging Attorney General Alberto R. Gonzales to argue at a White House meeting in May 2005 that it was “wrong.”
“In stark terms I explained to him what this would look like some day and what it would mean for the president and the government,” Mr. Comey wrote in a May 31, 2005, e-mail message to his chief of staff, Chuck Rosenberg. He feared that a case could be made “that some of this stuff was simply awful.”
