At the trial of Chelsea Manning, the government could point to no case of specific damage that had been caused by the massive revelation of classified information. The charges are a reaction to the government's embarrassment more than genuine concern about these activities, or they would substantiate what harms were done.

It's clear the CIA was trying to play 'keep away' with documents relevant to an investigation by their overseers in Congress, and that's a serious constitutional concern. But it's equally if not more concerning that we're seeing another 'Merkel Effect,' where an elected official does not care at all that the rights of millions of ordinary citizens are violated by our spies, but suddenly it's a scandal when a politician finds out the same thing happens to them.

The majority of terrorist attacks that have been disrupted in the United States have been disrupted due to things like the Time Square bomber, who was caught by a hotdog vendor, not a mass surveillance program, not a cyber-espionage campaign.

We are all today being monitored in advance and in criminal suspicion. And I think that's terrifying, and deeply illiberal as concept. And that's something that we should reject.

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.

We don't like to use the phrase "state security" in the United States because it reminds us of all the bad regimes. But it's a key concept, because when these officials are out on TV, they're not talking about what's good for you. They're not talking about what's good for business. They're not talking about what's good for society. They're talking about the protection and perpetuation of a national state system.

When the US government got word that I was planning to leave Russia to go to Latin America, they brought down the plane of the - the presidential plane, which had diplomatic protection, that had the Bolivian president on board. They closed the airspace in four different countries in Europe, I believe, which was extraordinary, unprecedented.
