Just one note regarding this not-at-all magnificent testimony from Edward Snowden (although more could be said: see link at the bottom).
"I will leave the public interest determinations as to which of these may be safely disclosed to responsible journalists in coordination with government stakeholders."
So great of Snowden to remind us that he's comfortable with established journalists and government peeps decide what should be revealed to us, the plebs, regarding all this mass surveillance thingy.
So far, those two classes of superior citizens have done such a marvelous job at working for the common good, including making sure that less than 5% of all the data he amassed before flying off to Hong-Kong is ever released/revealed.
So thanks for all the state-sponsored whistle-blowing, friend.
