At the age of 19, Murat Kurnaz vanished into America’s shadow prison system in the war on terror. He was from Germany, traveling in Pakistan, and was picked up three months after 9/11. But there seemed to be ample evidence that Kurnaz was an innocent man with no connection to terrorism. The FBI thought so, U.S. intelligence thought so, and German intelligence agreed. But once he was picked up, Kurnaz found himself in a prison system that required no evidence and answered to no one.
