I have used mass surveillance to target people, so I do know how it works.

Citizens have to fight suppression of information on matters of vital public importance. To tell the truth is not a crime.

All this is a blessing and a curse. It's a blessing because it helps people establish what they value; they understand the sort of ideas they identify with. The curse is that they aren't challenged in their views. The Internet becomes an echo chamber. Users don't see the counterarguments.

The community of technical experts who really manage the internet, who built the internet and maintain it, are becoming increasingly concerned about the activities of agencies like the NSA or Cyber Command, because what we see is that defense is becoming less of a priority than offense.

When people conceptualize a cyber-attack, they do tend to think about parts of the critical infrastructure like power plants, water supplies, and similar sort of heavy infrastructure, critical infrastructure areas. And they could be hit, as long as they're network connected, as long as they have some kind of systems that interact with them that could be manipulated from internet connection.

Your rights matter, because you never know when you're going to need them.

Governments cannot require individuals, they cannot require the public as a body, and they cannot require corporations to make investigation and law enforcement easy for them in a liberal society.
