I think that's actually what's missing from government, for the most part. We've got a lot of policy people, but we have no technologists, even though technology is such a big part of our lives. It's just amazing, because even these big Silicon Valley companies, the masters of the universe or whatever, haven't engaged with Washington until recently. They're still playing catch-up.

I think it's reasonable that the government, when it has a warrant from a court, when it's exposed to scrutiny by a legal process that would be upheld, not just nationally, but internationally as a reliable and robust standard rights protection, they can enjoy certain powers. This is no different from having the police able to get a warrant to go and search your house, to kick at your door because they think you're an arms dealer or something like that. There needs to be a process involved, it needs to be public, and it needs to be challengeable in court at all times.

We need the security standards to apply to the internet. We need to be able to trust that when we send our emails through Verizon, that Verizon isn't sharing with the NSA, that Verizon isn't sharing them with the FBI or German intelligence or French intelligence or Russian intelligence or Chinese intelligence.

The work of a generation is beginning here, with your hearings, and you have the full measure of my gratitude and support.

The government doesn't want us to know what they're doing, how they're interpreting the law, how they're interpreting and redefining their powers, and increasingly, how they're redefining the boundaries of our rights and our liberties, broadly, socially, and categorically without our involvement.

Much of what I saw in Geneva really disillusioned me about how my government functions and what its impact is in the world. I realised that I was part of something that was doing far more harm than good.

I love my country. I love my family. And I have dedicated my life to both of them.
