Lawyers for accused Army whistleblower Bradley Manning have opened their defense at his military court-martial with a bid to dismiss a number of charges, including aiding the enemy. We're joined by the former chief prosecutor at Guantánamo Bay, Col. Morris Davis, who has just wrapped two days of testimony for the defense. Davis told the court that many of the files Manning leaked on Guantánamo were already out in the public and that they had no value to enemy groups and could not have harmed U.S. national security. We're also joined from Fort Meade, Maryland, by Kevin Gosztola, a civil liberties blogger covering the trial for Firedoglake.com and co-author of "Truth And Consequences: The U.S. vs. Bradley Manning."
