We are all today being monitored in advance and in criminal suspicion. And I think that's terrifying, and deeply illiberal as concept. And that's something that we should reject.

Using the language of heroism, calling Daniel Ellsberg a hero, and calling the other people who made great sacrifices heroes - even though what they have done is heroic - is to distinguish them from the civic duty they performed, and excuses the rest of us from the same civic duty to speak out when we see something wrong, when we witness our government engaging in serious crimes, abusing power, engaging in massive historic violations of the Constitution of the United States. We have to speak out or we are party to that bad action.

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?

Custom developed digital weapons, cyber weapons nowadays typically chain together a number of zero-day exploits that are targeted against the specific site, the specific target that they want to hit. But it depends, this level of sophistication, on the budget and the quality of the actor who's instigating the attack. If it's a country that's less poor or less sophisticated, it'll be a less sophisticated attack.

The [George W.] Bush administration marked a very serious and profoundly negative turning point - not just for the nation, but for the international order, because we started to govern on the idea of "might makes right." And that's a very old, toxic and infectious idea.

The NSA has built an infrastructure that allows it to intercept almost everything. With this capability, the vast majority of human communications are automatically ingested without targeting. If I wanted to see your emails or your wife's phone, all I have to do is use intercepts. I can get your emails, passwords, phone records, credit cards.

Defending ourselves from internet-based attacks, internet-originated attacks, is much, much more important than our ability to launch attacks against similar targets in foreign countries.
