We hack everyone everywhere. We like to make a distinction between us and the others. But we are in almost every country in the world. We are not at war with these countries.

In liberal societies we don't typically require citizens to rearrange their activities, their lives, the way they go about their business, to make it easy for the police to do their work.

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.

Imagine, if you will, you're sitting at my desk in Hawaii. You have access to the entire world, as far as you can see it. Last several days, content of internet communications. Every email that's sent. Every website that's visited by every individual. Every text message that somebody sends on their phone. Every phone call they make.

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

We can't simply scare people into giving up their rights, on the basis, oh, this protects us from terrorism.

I'm still working for the government.
