Look at the reactions of liberal governments to the surveillance revelations during the last years. In the United States, we've got this big debate, but we've got official paralysis - because they're the ones who had their hand caught most deeply in the cookie jar.

I acted on my belief that the NSA's mass surveillance programs would not withstand a constitutional challenge, and that the American public deserved a chance to see these issues determined by open courts. Today, a secret program authorized by a secret court was, when exposed to the light of day, found to violate Americans' rights. It is the first of many.

Every time we walk on to the field of battle and the field of battle is the internet, it doesn't matter if we shoot our opponents a hundred times and hit every time. As long as they've hit us once, we've lost, because the U.S. is so much more reliant on those systems.

And that's not something I'm willing to support, it's not something I'm willing to build and it's not something I'm willing to live under.

If we can't have an open and honest debate about the value of ideas in a university in Glasgow, or Boston, or anywhere else in the world, then where are they going to go?

We have these traditional political parties that are less and less responsive to the needs of ordinary people, so people are in search of their own values.

The internet is the most complex system that humans have ever invented. And with every internet enabled operation that we've seen so far, all of these offensive operations, we see knock on effects. We see unintended consequences.
