The story of Edward Snowden -- who was still in Hong Kong at the time -- and the trial of Bradley Manning made me think of putting together a list of famous whistleblowers through history. This is a fun read with a lot of names here you might know -- Mark "Deep Throat" Felt and Daniel "Pentagon Papers" Ellsberg -- and maybe a few you've never heard of. I managed to include one of my favorites, Billy Mitchell and Mark Whitacre, played by Matt Damon in a really funny movie a few years ago. June 24, 2013.
