The Justice Department memo that was made public yesterday touches on a number of important issues, but it leaves many of the most important questions about the President's lethal authorities unanswered. Questions like 'how much evidence does the President need to decide that a particular American is part of a terrorist group?', 'does the President have to provide individual Americans with the opportunity to surrender?' and 'can the President order intelligence agencies or the military to kill an American who is inside the United States?' need to be asked and answered in a way that is consistent with American laws and American values. This memo does not answer these questions.
