An extremely well done documentary covering Gitmo and Abu Ghraib. The website is also very well done with a link to the entire documentary to view over the computer.
They talk to a number of people that were there including General Rick Baccus (In charge of Gitmo 2002), Colonel Janis Karpinski (in command of Abu Ghraib during abuses), as well as a number of interrogators, FBI involved, General Jack Keane who was sent to investigate Gitmo, etc.
I sat down last night and watched it, very very cool beans.
