One man lost his eye. Another’s rectum was so damaged he can’t sit without a pillow. A third was strung up naked on a pole for two days. These men are the first to speak up about their experiences at C.I.A. detention sites and places like Guantanamo. Until recently, the detainees were bound to silence because the details surrounding their treatment were considered classified. But now the U.S. government is loosening its definition of classified information, allowing current and former prisoners to talk about their memories and experiences of being tortured. But was the restriction legal in the first place?
