We need to think about encryption not as this sort of arcane, black art. It's a basic protection.

Anyway, it's not true that the authorities cannot access the content of the phone even if there is no back door. When I was at the NSA, we did this every single day, even on Sundays. I believe that encryption is a civic responsibility, a civic duty.

Are our competitors - for example, China, which is a deeply authoritarian nation - becoming more authoritarian or more liberal over time?

I would say the first key concept is that, in terms of technological and communication progress in human history, the Internet is basically the equivalent of electronic telepathy. We can now communicate all the time through our little magic smartphones with people who are anywhere, all the time, constantly learning what they're thinking, talking about, exchanging messages. And this is a new capability even within the context of the Internet.

My case clearly demonstrates the need for comprehensive whistleblower protection act reform. If we had had a real process in place, and reports of wrongdoing could be taken to real, independent arbiters rather than captured officials, I might not have had to sacrifice so much to do what at this point even the President seems to agree needed to be done.

The most important thing to the United States is not being able to attack our adversaries, the most important thing is to be able to defend ourselves. And we can't do that as long as we're subverting our own security standards for the sake of surveillance.

Presidents should not be exempted from the same standards of reason and evidence and justification that any other citizen or civil movement should be held to.
