I don't want to live in a world where everything that I say, everything I do, everyone I talk to, every expression of creativity or love or friendship is recorded.

I don't think there's anything, any threat out there today that anyone can point to, that justifies placing an entire population under mass surveillance.

US administration does not want me to return. People forget how I ended up in Russia. They waited until I departed Hong Kong to cancel my passport in order to trap me in Russia, because it's the most effective attack they have against me, given the political climate in the United States.

I've got more than enough for my needs [for social life in Moscow], let's put it that way.

The great fear that I have regarding the outcome for America of these disclosures is that nothing will change. [People] won't be willing to take the risks necessary to stand up and fight to change things And in the months ahead, the years ahead, it's only going to get worse. [The NSA will] say that because of the crisis, the dangers that we face in the world, some new and unpredicted threat, we need more authority, we need more power, and there will be nothing the people can do at that point to oppose it. And it will be turnkey tyranny.

The power of the presidency is important, but it is not determinative.

Internet exchanges and internet service providers - international fiber optic landing points - these are the key tools that governments go after in order to enable their programs of mass surveillance. If they want to be able to watch the entire population of a country instead of a single individual, you have to go after those bulk interchanges.
