Terrorism kills far fewer people than cigarettes, or alcohol, or car accidents. But we don't see ourselves restructuring society and lives in order to make those threats go away.

Before 2013, if you said the NSA was making records of everybody's phone calls and the [Government Communications Headquarters] was monitoring lawyers and journalists, people raised eyebrows and called you a conspiracy theorist. Those days are over.

I do not expect to see home again.

America is a fundamentally good country. We have good people with good values who want to do the right thing. But the structures of power that exist are working to their own ends to extend their capability at the expense of the freedom of all publics.

We have to argue forcefully and demand that the government recognise that these programmes do not prevent - mass surveillance does not prevent acts of terrorism.

When it comes to the internet, when it comes to the United States' technical economy, we have more to lose than any other nation on earth.

When we look at the full-on mass surveillance watching everyone in the country, in the United States, it doesn't work. It didn't stop the attacks in Boston. The marathon bombings. Where again, we knew who these individuals were. It didn't stop the Underwear Bomber, whose father walked into an embassy and warned us about this individual before he walked onto an airplane. And it's not going to stop the next attacks either. Because again, they're not public safety programmes. They're spying programmes. They are valuable for spying.
