Snowden, you idiot; make a stand.
Yes you did personally release classified information... to the press.
It's the public who will sit in the jury seat and judge you. If you truly believe you did the right thing for the USA, then go back and plead your case in court. You only have to convince 1 juror.
Those who've made a stand against the government and won by getting the people behind them, never did it from outside the country. They were brave enough to keep their chin up. They didn't run like a coward and shout insults from a distant land.
