We're now more than a year since my NSA revelations, and despite numerous hours of testimony before Congress, despite tons of off-the-record quotes from anonymous officials who have an ax to grind, not a single US official, not a single representative of the United States government, has ever pointed to a single case of individualized harm caused by these revelations.

Even though it seems so obvious now, it is extraordinary in the context of the last decade, because courts had simply said they were not the best branch to adjudicate these claims - which is completely wrong, because they are the only nonpolitical branch. They are the branch that is specifically charged with deciding issues that cannot be impartially decided by politicians.
