In other words, while the CIA may have learned the courier’s nickname earlier, they didn’t learn his true name until “four years ago”–so late 2006 at the earliest. And they didn’t learn where the courier operated until around 2009.
From these dates we can conclude that either KSM shielded the courier’s identity entirely until close to 2007, or he told his interrogators that there was a courier who might be protecting bin Laden early in his detention but they were never able to force him to give the courier’s true name or his location, at least not until three or four years after the waterboarding of KSM ended. That’s either a sign of the rank incompetence of KSM’s interrogators (that is, that they missed the significance of a courier protecting OBL), or a sign he was able to withstand whatever treatment they used with him.
Marcy reads the Cheney statement saying he "assumes" that torture led to bin Laden differently because he "admits he doesn’t know where the intelligence came from." She's spot on in pointing out that the failure of Cheney to take full credit for the torture policy he loves so much, and spent so much time propagandizing. She says, since he "can’t claim definitively that the intelligence came from it, is a pretty good tell that he can’t say it did." She also points out that Donald Rumsfeld, who would have every reason to crow that the policies he supported had a good outcome, will only go so far as to say the intelligence might have come from detainees at Guantanamo.
Note clearly that neither of these two endorsing the idea that the waterboarding of KSM nine years ago—all 183 incidents of it—led to the name and location of the courier, which current intelligence officials say they learned in the last four years. It's not even clear that KSM's interrogators were even interested then in obtaining information about the couriers. The timeline, and every report that says the specific information on the courier was obtained in recent years at Guantanamo make the KSM waterboarding story incredible.
Dick Cheney still says "We need to keep in place those policies that made it possible for us to succeed in this case," meaning torture. He's still wrong.
