How do we preserve our civil rights, our traditions as a liberal democracy, in a time when government power is expanding and is more and more difficult to check?

All I was was a mechanism.

I carefully evaluated every single document I disclosed to ensure that each was legitimately in the public interest. There are all sorts of documents that would have made a big impact that I didn't turn over, because harming people isn't my goal. Transparency is.

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?!"

One of the reasons that I came forward and sort burned of my life to the ground, and I can't go back and see my family in the United States - I obviously lost my job, which I was quite comfortable with. I lost my home. It was because I felt there was no alternative.

An investigation found the specific people who authorized the warrantless wiretapping of millions and millions of communications, which per count would have resulted in the longest sentences in world history, and our highest official simply demanded the investigation be halted. Who "can" be brought up on charges is immaterial when the rule of law is not respected. Laws are meant for you, not for them.

The question is: Particularly in the post-9/11 era, are societies becoming more liberal or more authoritarian?
