Privacy is a function of liberty.

The government has granted itself power it is not entitled to. There is no public oversight. The result is people like myself have the latitude to go further than they are allowed to.

The majority of terrorist attacks that have been disrupted in the United States have been disrupted due to things like the Time Square bomber, who was caught by a hotdog vendor, not a mass surveillance program, not a cyber-espionage campaign.

I've got more than enough for my needs [for social life in Moscow], let's put it that way.

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

The sad truth is that societies that demand whistleblowers be martyrs often find themselves without either, and always when it matters the most.

I'm familiar with Andrei Sakharov reputation, but I don't know his personal history at all.
