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.

Technology provides us means outside of governments to begin enforcing our rights, enforcing protection of civil liberties, regardless of law, through the implementation of systems and standards.

When I talk about the polling, I'm talking about the principles. It shows these officials are knowingly attempting to shift public opinion, even though they know what they say is not factual.

People have to be free to investigate computer security. People have to be free to look for the vulnerabilities and create proof of concept code to show that they are true vulnerabilities in order for us to secure our systems.

We have to decide why terrorism is a new threat. There has always been terrorism.

When it comes to cyber conflicts between, say, America and China or even a Middle Eastern nation, an African nation, a Latin American nation, a European nation, we have more to lose.

It's much easier, I think, to protect communications while they're in transit at least, than it is to enforce legislation in every country in the world to say that you can't do this.
