An ex-CIA technician believed to be behind one of the worst leaks in agency history says the conditions at the federal jail in lower Manhattan are so bad that he'd rather be a prisoner in North Korea. Joshua Schulte ... described the Metropolitan Correctional Center as a living hell where inmates are dragged from their cages and beaten and maced," forced to bathe in "s-t-filled showers," thrown into solitary confinement for no reason and improperly barred from communicating with their lawyers. "They even refuse us pens and stamps so we can't even write," Schulte told a judge in a letter that he says he was only able to write after he borrowed a pen from a medical assistant. The ex-CIA software engineer has been in the MCC since last year after the feds raided his New York apartment on suspicion that he had leaked classified documents to WikiLeaks. Immediately following the raid, he was ... charged with possession of kiddie porn. It wasn't until this year that the feds slapped Schulte with a 13-count superseding indictment for leaking classified information, including national defense information, that he believed could be used "to the injury of the United States and the advantage of a foreign nation." The MCC has been the target of numerous complaints in recent months. Reputed mobster John "Porky" Zancocchio recently got sprung from the lockup, where he was sent for a bail violation, after his lawyer complained that the food there was hurting his client's already failing health.
