I had been looking for leaders, but I realized that leadership is about being the first to act.

You are also asked to take an oath, and that's the oath of service. The oath of service is not to secrecy, but to the Constitution - to protect it against all enemies, foreign and domestic. That's the oath that I kept, that James Clapper and former NSA director Keith Alexander did not. You raise your hand and you take the oath in your class when you are on board. All government officials are made to do it who work for the intelligence agencies - at least, that's where I took the oath.

I'm ultimately satisfied that we know a little bit more about how the world really works.

We have to recognise that rights are being violated. The United Nations actually filed a report that found that that was the case, that mass surveillance is a violation of rights.

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?!"

The United States need to be focusing more on creating a more secure, more reliable, more robust, and more trusted internet, not one that's weaker, not one that relies on this systemic model of exploiting every vulnerability, every threat out there.

I do not want to live in a world where everything I do and say is recorded. That is not something I am willing to support or live under.
