Karen Greenberg, director of the Center on National Security at Fordham Law School, discusses the start of the Guantanamo terror trial and the revelation that a top Al-Qaeda operative was a CIA double-agent.

Attorney General Eric Holder outlined the United States’ legal defense of using lethal force against U.S. citizens overseas if that citizen is posing a terrorist threat. Holder’s speech, delivered Monday afternoon at Northwestern University, argued in part that the U.S. Constitution’s definition of due process defends the use of lethal force, even without the written consent of the president.

Until now, no legal defense was given for the U.S. mission in Yemen which killed al-Qaeda’s leading figure Anwar al-Awlaki. Al-Awlaki, who was born in the US, was the radical cleric who successfully took al-Qaeda’s message to YouTube.
