Snowden Reveals How He Secretly Exposed NSA Criminal Wrongdoing Without Getting Arrested

Edward Snowden talks about his decision to leak documents to journalists Glenn Greenwald and Laura Poitras rather than WikiLeaks, and the issues with the U.S. government's response to whistleblower disclosures. His recently published memoir, "Permanent Record," tells the story of his decision to expose the system of mass surveillance. "I think it's so obvious that no harm to national security has resulted from this process of disclosure. And yet, the same criticisms, the same allegations are made to me as have been every other whistleblower," Snowden says. "What we need to understand here is not my model of publication is right and WikiLeaks' model is wrong, but rather to see you have two very different levels of caution, of risk mitigation in these publication models."
