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.

Using the language of heroism, calling Daniel Ellsberg a hero, and calling the other people who made great sacrifices heroes - even though what they have done is heroic - is to distinguish them from the civic duty they performed, and excuses the rest of us from the same civic duty to speak out when we see something wrong, when we witness our government engaging in serious crimes, abusing power, engaging in massive historic violations of the Constitution of the United States. We have to speak out or we are party to that bad action.

Bulk collection means all of your communications are being secretly intercepted. They are being stolen as they cross India, and they're being stored in these silos so that they can be rifled through at the convenience of secret agents, basically.

People in both parties from the congressional intelligence committees - all these co-opted officials who play cheerleader for spy agencies - go on these Sunday shows and they say: "Snowden was a traitor. He works against Americans. He works for the Chinese. Oh, wait, he left Hong Kong - he works for the Russians."

No one would argue that it's in the United States' interest to have independent knowledge of the plans and intentions of foreign countries. But we need to think about where to draw the line on these kind of operations so we're not always attacking our allies, the people we trust, the people we need to rely on, and to have them in turn rely on us.

When it comes to cyber warfare, we have more to lose than any other nation on earth. The technical sector is the backbone of the American economy, and if we start engaging in these kind of behaviors, in these kind of attacks, we're setting a standard, we're creating a new international norm of behavior that says this is what nations do. This is what developed nations do.

We don't have a great clash of civilizations, a clash of ideologies, a clash of alternative models, where governments thought to themselves, if we go too far, if we sort of trample unreasonably on rights, we'll give birth to a political movement which will cost us our credibility, and will possibly cost us our offices, because people will vote for the other team, the other guys.
