"I'm writing this on my 21st visit to Guantanamo Bay. I'm visiting Binyam Mohammed. the British resident tortured for 18 months in Morocco. The abuses were medieval for the most part, including a razor blade to his genitals, but I was surprised when he told me the psychological tactics were worse than the physical torture. He explained it well: given the terrible choice between losing your sight or losing your mind, anyone would choose to be blinded over becoming insane."
