GOSS: Let me put it this way, I'm not going to comment on any individual techniques that anybody has brought forward as an allegation, or dreamed up or anything like that. What we do, as I said many times, is professional, it's lawful, it yields good results and it is not torture.
The CIA has had in the past and may indeed have in practice right now a history of hiring people who could be fully disavowed. A good fictional version is in the movie Confessions of a Dangerous Mind So Goss could quite clearly say We meaning the US Government, or more specifically the CIA don't do torture.
This could mean a independent entity with no contact or control from the CIA is doing the waterboarding.
If this is the case Sully's sources would be right and so would Goss.
Or... it could be another government entity ( say the NSA for example) and again the contacts would be right as would Goss because another government agent -could- be torturing inside a secret CIA facility.
But Sully is more intrested in trying to make Goss look bad. And fails miserably
