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.

We have to call mass surveillance mass surveillance. We can't let governments around the world redefine, and sort of weasel their way out of it by saying this is bulk collection.

You simply have to eventually fall under suspicion from somebody even by a wrong call. And then they can use this system to go back in time and scrutinize every decision you've ever made, every friend you've ever discussed something with. And attack you on that basis to sort to derive suspicion from an innocent life and paint anyone in the context of a wrongdoer.

America should be cooling down the tensions in the internet, making it a more trusted environment, making it a more secure environment, making it a more reliable environment, because that's the foundation of our economy and our future.
