Former CIA officer John Kiriakou is the only CIA employee connected to its interrogation program to go to prison. But he was prosecuted for providing information to reporters, not for anything connected to ... torture." No other person connected to the program has been charged with a crime, after the Justice Department said their actions had been approved legally or that there was not sufficient admissible evidence in a couple cases of potential wrongdoing, even in light of the death of two detainees in the early 2000s. Kiriakou was the first person with direct knowledge of the CIA interrogation program to publicly reveal its existence, in an interview with ABC News in 2007. He is now serving a nearly-three-year prison sentence for violating the Intelligence Identities Protection Act, but he says that's only what the government wants people to believe. "In truth, this is my punishment for blowing the whistle on the CIA's illegal torture program and for telling the public that torture was official U.S. government policy," Kiriakou said in a letter last May from a prison in Loretto, Penn. In his groundbreaking interview with ABC News and later with other news outlets, Kiriakou described the details of the program. In some cases, it turned out that even Kiriakou ... was misled or kept in the dark about the extent of the program.
