At the very end of Froomkin's chat yesterday, there is this little gem:

Stony Brook, N.Y.: Everybody seems to accept the claim that the CIA tapes were destroyed. Given the long history of deceptions by this administration, shouldn't we ask for proof, or at least sworn statements to that effect?

Dan Froomkin: A good point. And consider this. Michael Isikoff and Mark Hosenball write in Newsweek: "At one point portions of the tapes were electronically transmitted to CIA headquarters in Langley, Va., so a small number of officials there could review them. A counterterrorism source, who also asked for anonymity when discussing this subject, said that there was no reason to believe that any recordings of such an electronic feed still exist."

No, no, of course not. No reason whatever. (Except that, as we know from the Stasi and, say, Guatemala, totalitarian regimes hang onto all their data.)

And who knows the dataflows? Where the data goes, its nature and volume, its timing, and who has privileges to see it? The techs. Could we talk to them, please? Didn't we get good results when we talked to Alexander Butterfield?
