PFC Bradley Manning has pled guilty to releasing 700,000 classified documents, which WikiLeaks then published on the Internet — the largest intelligence breach in American history. At the time, Manning worked in what's called a "Sensitive Compartmented Information Facility" at Forward Operating Base Hammer near Baghdad. He's now facing a court martial on espionage charges at Fort Mead, Maryland. Critics say he betrayed his country. His defenders are framing the case, in part, as a challenge to what they call excessive classification of information the public has a right to know. Is he a whistle-blower or a traitor who deserves life in prison?
