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.

I don't think political reform is likely to succeed. [Senators Tom] Udall and [Ron] Wyden, on the intelligence committee, have been sounding the alarm, but they are a minority.

I built my own studio. I don't have the professional language to describe it because I'm not a videographer - but I'm a technician. So I get the camera, I get all the things that translate the camera to the computer, I set up a live session, I do the security on it, I set up a background so I can key it out, like newscasters do, and replace it with whatever I want - and I can be anywhere I need to be.

[Bill] Binney will argue with you all day about ThinThread, but his idea was that it would collect everything about everybody but be immediately encrypted so no one could read it. Only a court could give intelligence officials the key to decrypt it. The idea was to find a kind of a compromise between [privacy rights and] the assertion that if you don't collect things as they happen, you won't have them later - because what the NSA really wants is the capability of retrospective investigation.

When the US government got word that I was planning to leave Russia to go to Latin America, they brought down the plane of the - the presidential plane, which had diplomatic protection, that had the Bolivian president on board. They closed the airspace in four different countries in Europe, I believe, which was extraordinary, unprecedented.

Your rights matter, because you never know when you're going to need them.

Many of our ally states don't have these constitutional protections - in the UK, in New Zealand, in Australia. They've lost the right to be free from unreasonable search and seizure without probable cause. All of those countries, in the wake of these surveillance revelations, rushed through laws that were basically ghostwritten by the National Security Agency to enable mass surveillance without court oversight, without all of the standard checks and balances that one would expect.
