When we have some horrible terrorist attacks happen in some country we see in the recording that follows, that the intelligence community already knew about these people in advance. We know that these countries were involved in intelligence sharing premiums, that they benefited from mass surveillance, and yet they didn't stop the attacks. Yet at the same time we immediately see intelligence officials running to the newspapers and claiming that we need more surveillance, that we need more intrusion, that we need more expense of powers because it could have stopped an attack.

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.

There have been so many individuals who have really put a lot on the line. That they've sacrificed so much to try to protect the principle of source protection in the journalism world. And I think Julian Assange, and WikiLeaks, and Sarah Harrison have really been extraordinary in standing up for that.

A child born today will grow up with no conception of privacy at all. They'll never know what it means to have a private moment to themselves an unrecorded, unanalysed thought. And that's a problem because privacy matters, privacy is what allows us to determine who we are and who we want to be.

Bathtub falls and police officers kill more Americans than terrorism, yet we've been asked to sacrifice our most sacred rights for fear of falling victim to it.

We need the security standards to apply to the internet. We need to be able to trust that when we send our emails through Verizon, that Verizon isn't sharing with the NSA, that Verizon isn't sharing them with the FBI or German intelligence or French intelligence or Russian intelligence or Chinese intelligence.

By creating a self-policing, self-reporting, sort of self-monitoring culture through law, through statute, and imposing that on the academic world, I think not only are we losing a significant measure of freedom in academic traditions and in our civil society, but we're actually making ourselves less competitive with every other country around the world that does not do that. Because that's where researchers are going to go and that's where academics are going to go. And ultimately, that's where breakthroughs are going to occur.
