Just in case anyone needed a box set to view, I can recommend this. I had taped it when it was on but only just got around to watching.
The interrogation scenes are a bit shit, it's all a bit too easy, but other than that it worth a watch.
It's also quite informative how the US agencies "work" and the politics behind some decisions. A lot of people don't come out of it too well.
Also some stuff I didn't know about, but have checked and read up on since.
