[Bill] Binney will argue with you all day about ThinThread, but his idea was that it would collect everything about everybody but be immediately encrypted so no one could read it. Only a court could give intelligence officials the key to decrypt it. The idea was to find a kind of a compromise between [privacy rights and] the assertion that if you don't collect things as they happen, you won't have them later - because what the NSA really wants is the capability of retrospective investigation.

The NSA has built an infrastructure that allows it to intercept almost everything. With this capability, the vast majority of human communications are automatically ingested without targeting. If I wanted to see your emails or your wife's phone, all I have to do is use intercepts. I can get your emails, passwords, phone records, credit cards.

The problem is when [the state] monitor all of us, en masse, all of the time, without any specific justification for intercepting in the first place, without any specific judicial showing that there's a probable cause for that infringement of our rights.

As a general rule, so long as you have any choice at all, you should never route through or peer with the UK under any circumstances. Their fibers are radioactive, and even the Queen's selfies to the pool boy get logged.

They are intent on making every conversation and every form of behaviour in the world known to them.

When it comes to political engagement, I'm not a politician - I'm an engineer.

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.
