"In their self-protective understanding of the duties of high office in the national security state—in their refusal to face up to and reform the ungoverned exercise of power that Snowden revealed—Obama and Holder acted in a way that showed them to be profoundly unfree. So, too, did the generals, Keith Alexander and James Clapper, when they spoke under oath to Congress with so little regard for the importance of truth in a system that depends on informed consent.
"The strangest revelation of Citizenfour may therefore be this: Snowden, in his hotel room with his journalistic confidants Greenwald and Poitras and MacAskill, affords a picture of a free man. It shows in his posture, and in a sense of humor touched by self-irony. He is not haunted by any fretful concern with what comes next. He is sure he has done something he chose, and sure that someone had to do it. He acted in obedience to a principle; and it was right that the actor should disappear in the action."
