This guy was involved in two assassination attempts against Musharraf. I don't think his life is very pleasant right now. If, or when, he is handed over to the U.S., his nickname will probably be "stumpy."
Any Paki interogation would have heavy influence by our CIA, Mossad, the works. Lots of sensory deprivation and confusion. Frankly the notebook he carried would be dyn-o-mite info. Impressions left by previous writings can go 10 pages or more back in time. Al Qaeda is now gone to ground and remote control, those notebooks are for dispatches to couriers and is all they have left for secured communications.
