Andy Worthington has written an extraordinary book, The Guantánamo Files: The Stories of the 774 Detainees in America’s Illegal Prison, that provides the only thorough accounting of the nearly 800 men who have passed through the US detention facility at Guantanamo Bay. In it, he provides the most thorough accounting of who they are, how they got there, how they were treated in US custody, and most shockingly, how few of them were actually involved in any kind of terrorist activity against the United States or its allies.
