Our rights are not granted by governments. They are inherent to our nature. But it's entirely the opposite for governments: their privileges are precisely equal to only those which we suffer them to enjoy.

I'm not a politician, and I do not think I am as effective in this way as people who actually prepare for it - is to focus on technical reform, because I speak the language of technology. I spoke with Tim Berners-Lee, the guy who invented the World Wide Web. We agree on the necessity for this generation to create what he calls the Magna Carta for the Internet. We want to say what "digital rights" should be. What values should we be protecting, and how do we assert them.

I believe that when [senator Ron] Wyden and [senator Mark] Udall asked about the scale of this, they [the NSA] said it did not have the tools to provide an answer. We do have the tools and I have maps showing where people have been scrutinised most. We collect more digital communications from America than we do from the Russians.

People at civil-liberties organizations say it's a sea change, and that it's very clear judges have begun to question more critically assertions made by the executive. Even though it seems so obvious now, it is extraordinary in the context of the last decade, because courts had simply said they were not the best branch to adjudicate these claims - which is completely wrong, because they are the only nonpolitical branch. They are the branch that is specifically charged with deciding issues that cannot be impartially decided by politicians.

There are times throughout history and it doesn't take long for either an American or a German, to think about times in the history of their country where the law provided the Government to do things which were not right.

When you think about the abolition of slavery for example, for the ruling class with the rich white people owning plantations and states, and things like that, slavery was to their benefit. To oppose it didn't make any sense at all on a rational basis. But on a rights basis, on a principle basis, it made obvious, overwhelming sense.
