Daphne Eviatar sets the scene:

The American Civil Liberties Union has just released a video of interviews with five former Guantanamo detainees, talking about their experiences of abuse in U.S. custody. It’s not easy to watch, but it’s certainly worthwhile. [...T]he fact that all the men were eventually released without charge suggests, at least, that the Bush administration’s claim that they were among “the worst of the worst” didn’t turn out to be true. The video also gives a strong sense of how and why the Guantanamo detention center, and the treatment of the men imprisoned there, ended up being a powerful recruiting tool for al-Qaeda.
