They [the authorities] will act aggressively against anyone who has known me. That keeps me up at night.

When it is made to appear as though not knowing everything about everyone is an existential crisis, then you feel that bending the rules is okay. Once people hate you for bending those rules, breaking them becomes a matter of survival.

If it comes to a question of law, the charges they brought against me - the Espionage Act - is called the quintessential political crime. A political crime, in legal terms, is defined as any crime against a state, as opposed to against an individual. Assassination, for example, is not a political crime because you've killed a person, an individual, and they've been harmed; their family's been harmed. But the state itself, you can't be extradited for harming it.

There have been so many individuals who have really put a lot on the line. That they've sacrificed so much to try to protect the principle of source protection in the journalism world. And I think Julian Assange, and WikiLeaks, and Sarah Harrison have really been extraordinary in standing up for that.

I've been recognized every now and then. It's always in computer stores. It's something like brain associations, because I'll be in the grocery store and nobody will recognize me. Even in my glasses, looking exactly like my picture, nobody will recognize me. But I could be totally clean-shaven, hat on, looking nothing like myself in a computer store, and they're like, "Snowden?!"

[Barton ] Gellman printed a great anecdote: he showed two Google engineers a slide that showed how the NSA was doing this, and the engineers "exploded in profanity."

By creating a self-policing, self-reporting, sort of self-monitoring culture through law, through statute, and imposing that on the academic world, I think not only are we losing a significant measure of freedom in academic traditions and in our civil society, but we're actually making ourselves less competitive with every other country around the world that does not do that. Because that's where researchers are going to go and that's where academics are going to go. And ultimately, that's where breakthroughs are going to occur.
