In a Democracy Now! broadcast exclusive, we speak with a former senior Pentagon official about how his superiors broke the law to punish a key National Security Agency whistleblower for leaking information about waste, mismanagement and surveillance. His account sheds light on how and why Edward Snowden revealed how the government was spying on hundreds of millions of people around the world. John Crane worked 25 years for the Department of Defense Office of Inspector General, which helps federal employees expose abuse. He now says whistleblowers have little choice but to go outside the system, and is speaking out about what happened to NSA whistleblower Thomas Drake, who revealed the existence of a widespread illegal program of domestic surveillance. Crane describes how in December 2010 Drake’s lawyers filed a complaint with the inspector general alleging he had been punished in retaliation for his whistleblowing, and that the crimes Drake was later charged with were "based in part, or entirely," on information he provided to the Pentagon inspector general. Mark Hertsgaard recounts Crane’s story in his new book, "Bravehearts: Whistle-Blowing in the Age of Snowden," and shows how Drake’s persecution sent an unmistakable message to Edward Snowden: Raising concerns within the system meant he would be targeted next. Edward Snowden has responded to Crane’s revelations by calling for a complete overhaul of U.S. whistleblower protections. "To me, the main issue is: Can we have a workable system that lets whistleblowers follow their own principled dissent without having them destroyed in the process?" asks John Crane. We are also joined by Mark Hertsgaard.
