Margulies, who was the lead attorney in the Supreme Court case Rasul v. Bush, writes that Guantánamo and other secret CIA and Defense Department detention centers around the world have become "prisons beyond the law," where the Administration claims the right to hold people indefinitely, incommunicado, and in solitary confinement without charges, access to counsel, and without benefit of the Geneva Conventions. Weaving together firsthand accounts of military personnel who witnessed the interrogations at Guantánamo along with the words of the prisoners themselves, Margulies exposes the chilling reality of a "war on terror" that masks an assault on basic human rights -- rights to which the United States has always subscribed.
