"I found out later that, NSA had approached the telecommunications companies in February of 2001, this is 8 months before 9/11 asking for all the customer data, that is the billing data on phone calls made from US citizens to other US citizens. In fact, the entire customer set. So, and that's fundamentally what they did after 9/11, here they were asking 8 months before. And what that meant to me was that this was the design from the beginning that management had made the plans to spy on the United States and people in the United States even before 9/11. Ok, then, when 9/11 occurred, that was the pure excuse for them to go in and say, 'now, telecoms, we really need the data now, to be able to do this to be, to protect the United States from terrorism.' and that was simply false to begin with. We had no problem at all identifying these people from the beginning."

“The US large-scale surveillance plan failed. It had to be abandoned in 2005. Checks afterwards showed that communications from the terrorists had been collected, but not looked at in time.”

“This is the research we did online for the 9/11 attacks ... we gave this briefing internally at the CIA, they said, 'how'd you know all this stuff?' because at the same time one of the emails had the date ... 9/11 as the attack date that was given”

“Incompetence at this scale, when they're doing things at this scale, is really dangerous, you could end up on a kill list without knowing what the criteria is to get on there or what the criteria is to get off.”

“In the early summer, the Russians started to train or exercise along the border with Czechoslovakia. I started looking at the communications they were using to move around and that's when I started to pick up some very small number of unique things that was different from a normal training programme. So I started to capture that, and I said: it's obvious that they're going to invade. It was only two days later that they actually invaded”

“This approach costs lives, and has cost lives in Britain because it inundates analysts with too much data. It is 99% useless. Who wants to know everyone who has ever at Google or the BBC? We have known for decades that that swamps analysts,”

“Since '1' identifies anyone in the regional zone 1 of the world, that's the US, Canada and some of the islands - it's right there in the front of your white pages book ... all they have to do is use that as a base of knowledge to go in to their entire database and count all of the phone numbers there that had a one in them, right-and then the ones are in the United States and then they'd have a count of how many Americans are in the database and how often each one's there. And yet they claim they can't do that, which is false. You can do the same thing with email, with service providers, IPs and things like that.”
