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 the United States cannibalize dollars from the defensive business of the NSA, securing our communications, protecting our systems, patching zero-day vulnerabilities, and instead we're giving those dollars to be used for creating new vulnerabilities in our systems so that they can surveil us and other people abroad who use the same systems.

Individuals have international duties which transcend the national obligations of obedience. Therefore individual citizens have the duty to violate domestic laws to prevent crimes against peace and humanity from occurring.

People at civil-liberties organizations say it's a sea change, and that it's very clear judges have begun to question more critically assertions made by the executive. Even though it seems so obvious now, it is extraordinary in the context of the last decade, because courts had simply said they were not the best branch to adjudicate these claims - which is completely wrong, because they are the only nonpolitical branch. They are the branch that is specifically charged with deciding issues that cannot be impartially decided by politicians.

When we look at the full-on mass surveillance watching everyone in the country, in the United States, it doesn't work. It didn't stop the attacks in Boston. The marathon bombings. Where again, we knew who these individuals were. It didn't stop the Underwear Bomber, whose father walked into an embassy and warned us about this individual before he walked onto an airplane. And it's not going to stop the next attacks either. Because again, they're not public safety programmes. They're spying programmes. They are valuable for spying.

The power of the presidency is important, but it is not determinative.

There's not much value to us attacking Chinese systems. We might take a few computers offline. We might take a factory offline. We might steal secrets from a university research programs, and even something high-tech. But how much more does the United States spend on research and development than China does?
