We've seen a departure from the traditional work of the National Security Agency. They've become sort of the national hacking agency, the national surveillance agency. And they've lost sight of the fact that everything they do is supposed to make us more secure as a nation and a society.

It's clear the CIA was trying to play 'keep away' with documents relevant to an investigation by their overseers in Congress, and that's a serious constitutional concern. But it's equally if not more concerning that we're seeing another 'Merkel Effect,' where an elected official does not care at all that the rights of millions of ordinary citizens are violated by our spies, but suddenly it's a scandal when a politician finds out the same thing happens to them.

For me, in terms of personal satisfaction, the mission's already accomplished. I already won. As soon as the journalists were able to work, everything that I had been trying to do was validated. Because, remember, I didn't want to change society. I wanted to give society a chance to determine if it should change itself.

The way the United States intelligence community operates is it doesn't limit itself to the protection of the homeland. It doesn't limit itself to countering terrorist threats, countering nuclear proliferation. It's also used for economic espionage, for political spying to gain some knowledge of what other countries are doing.

There is a policy response that needs to occur. There is also a technical response that needs to occur. It is the development community that can really craft the solutions and make sure we are safe.

When I was working in Japan, I created a system for ensuring that intelligence data was globally recoverable in the event of a disaster. I was not aware of the scope of mass surveillance. I came across some legal questions when I was creating it. My superiors pushed back and were like, "Well, how are we going to deal with this data?" And I was like, "I didn't even know it existed."

I don't care if I end up in jail or Guantánamo or whatever, kicked out of a plane with two gunshots in the face. I did what I did because I believe it is the right thing to do, and I will continue to do that.
