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.

Arguing that you don't care about privacy because you have nothing to hide is no different than saying you don't care about free speech because you have nothing to say.

The United States is more reliant on the technical systems. We're more reliant on the critical infrastructure of the internet than any other nation out there. And when there's such a low barrier to entering the domain of cyber-attacks we're starting a fight that we can't win.

There are cyber threats out there, this is a dangerous world, and we have to be safe, we have to be secure no matter the cost.

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.

Radicalism and extremism, while they are dangers, they exist in every society on some level.

You can't come up against the world's most powerful intelligence agencies and not accept the risk. If they want to get you, over time they will.
