Just consider the CIA and its effort to suppress the Senate's review of its torture program. Take in the fact that we live in a country that a) legalized torture and b) where no one was ever held to account for it, and now the government's internal look at what happened is being suppressed by the CIA. That's a frightening landscape to be in.

People are starting to understand that the devices we carry with us reveal our location, who we're talking to, and all kinds of other information.

Those who are experts in the fields of surveillance, privacy, and technology say that there need to be two tracks: a policy track and a technology track. The technology track is encryption. It works and if you want privacy, then you should use it.

I think it's radical to censor information because the government asks you to. That's radical.

One of the things that I think is true is that encryption actually is able to secure our communications, that every individual can use encryption, and that it's accessible and in many cases free.

One of the most frightening things, I think, is the capacity for retroactive searching, so you can go back in time and trace who someone is in contact with and where they've been.
