I'm not a communist, a socialist or a radical. But these issues have to be addressed.

To do that they, the NSA specifically, targets the communications of everyone. It ingests them by default. It collects them in its system and it filters them and it analyses them and it measures them and it stores them for periods of time simply because that's the easiest, most efficient, and most valuable way to achieve these ends. So while they may be intending to target someone associated with a foreign government or someone they suspect of terrorism, they're collecting you're communications to do so.

Too often we forget that social and political movements don't happen overnight. They don't bring change immediately - you have to build a critical mass of understanding of the issues.

When you're attacking a router on the internet, and you're doing it remotely, it's like trying to shoot the moon with a rifle. Everything has to happen exactly right. Every single variable has to be controlled and precisely accounted for. And that's not possible to do when you have limited knowledge of the target you're attacking.

People would publish their websites; other people would read them. But there was no real back and forth other than through e-mail. Web 2.0 was what they called the collaborative web - Facebook, Twitter, the social media.

It's important to remember when you start doing things like attacking hospitals through the internet, when you start attacking things like internet exchange points, when something goes wrong, people can die. If a hospital's infrastructure is affected, lifesaving equipment turns off.

I don't think there's anything, any threat out there today that anyone can point to, that justifies placing an entire population under mass surveillance.
