We've known since June that the US had held at least one "ghost" detainee off the books and without informing the Red Cross, in violation of the Geneva Conventions. The recent US Army reports into Abu Ghraib and prison abuse (which I still haven't got round to reading) apparently mention another seven cases. But now it seems the total could be up to a hundred - but the US Army (responsible for running the prisons) doesn't know exactly how many because the CIA won't tell them. I guess they're busy trying to cover their arses - and that of Donald Rumsfeld.
As for where this is going, put it together: dozens, maybe a hundred "ghost detainees" held in secret. Outright torture. Orders from the top. CIA stonewalling. It's looking more and more as if Seymour Hersh was right.
