If I target for example an email address, for example under FAA 702, and that email address sent something to you, Joe America, the analyst gets it. All of it. IPs, raw data, content, headers, attachments, everything. And it gets saved for a very long time - and can be extended further with waivers rather than warrants.

Maybe boutique media, maybe people who are reading papers and talking to academics and whatnot, maybe they understand, because they're high-information. But a lot of people are still unaware that I never intended to end up in Russia. They're not aware that journalists were live-tweeting pictures of my seat on the flight to Latin America I wasn't able to board because the US government revoked my passport.

Internet exchanges and internet service providers - international fiber optic landing points - these are the key tools that governments go after in order to enable their programs of mass surveillance. If they want to be able to watch the entire population of a country instead of a single individual, you have to go after those bulk interchanges.

In the United States the White House has appointed two different independent panels who had full access to classified information for the last 10 years that master balance has been in place in the United States, and they found that despite intercepting the calls - everybody in the country, - it had never stopped a single terrorist attack. So the question is, why would these officials be pursuing these policies, if we know they don't work, if they don't stop terrorism?

When we talk about the assertion of basically new government privileges with weak or no justification, we don't even have to look at international law to see the failings in them.

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

I've been watching The Wire recently.
