Former Vice President Dick Cheney is a "big supporter of waterboarding," but Gen. David Petraeus is not. "I have always been on the record, in fact, since 2003, with the concept of living our values," he said Sunday on NBC's "Meet the Press." "And I think that whenever we have, perhaps, taken expedient measures, they have turned around and bitten us in the backside . . . Abu Ghraib and other situations like that are nonbiodegradables. They don't go away. The enemy continues to beat you with them like a stick in the Central Command area of responsibility." Beyond that, Petraeus said, the approved interrogation methods work, so torture isn't needed. Also unlike Cheney, Petraeus favors closing the Guantanamo Bay detention facility.
