I don't want to live in a society that does these sort of things.

I know that fundamentally, changes to the fabric of the internet, and sort of our methods of communication, can enforce our rights.

When we talk about computer network exploitation, computer network attack, we're not just talking about your home PC. We're talking about your cell phone, and we're also talking about internet routers themselves. The NSA is attacking the critical infrastructure of the internet to try to take ownership of it. They hack the routers that connect nations to the internet itself.

You are also asked to take an oath, and that's the oath of service. The oath of service is not to secrecy, but to the Constitution - to protect it against all enemies, foreign and domestic. That's the oath that I kept, that James Clapper and former NSA director Keith Alexander did not. You raise your hand and you take the oath in your class when you are on board. All government officials are made to do it who work for the intelligence agencies - at least, that's where I took the oath.

I'm saying we need to be aware of it, and we need to be able to distinguish when political developments are occurring that are contrary to the public interest.

We need to think about encryption not as this sort of arcane, black art. It's a basic protection.

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.
