I went to a website the other day and right at the top of the page it showed me my ip address. It was the most disturbing moment I have ever experienced. This website even told me what internet browser I was using, and what day it was. Computers can do anything.

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."

What defines patriotism, for me, is the idea that one rises to act on behalf of one's country.

I was hoping to catch [Vladimir] Putin in a lie - like what happened to Director of National Intelligence James Clapper [in his congressional testimony]. So I asked Putin basically the same questions about Russian mass surveillance. I knew he's doing the same thing, but he denied it.

I can't in good conscience allow the U.S. government to destroy privacy, internet freedom and basic liberties for people around the world with this massive surveillance machine they're secretly building.

There's no question that the US is engaged in economic spying. If there's information at Siemens that they think would be beneficial to the national interests, not the national security of the United States, they'll go after that information and they'll take it.

I'm not a spy for Russia or China or any other country for that matter.
