..."To be sure, Snowden did not go to his supervisors or to the Congress. He did not do this because four other NSA whistleblowers (only three of whom are public) had already done it, and they had been subjected to demotion, termination and FBI raids. One of them was indicted under the Espionage Act and investigated for four years before the charges imploded. The unfortunate Congressional staffer who supported their allegations was also raided at home by the FBI and is now suing the government for the return of her personal effects.
Snowden did not follow this same course because he was aware of what had happened. He has said as much.

"Lord Snowden of Siberia, One Last Word (With an UPDATE)
I don't like writing about Snowden or the goofy-looking Manning. As I have said before, I consider both treasonous weasels. I must write something, however, given the puzzling argument of many folks, including conservatives and friends, who consider them, especially Snowden, some sort of heroic whistleblower figures, or Avengers for Justice and Freedom. I cannot agree with that; let me explain, and then will promise to try to avoid this topic."
