I would argue that security and liberty, security and privacy are not actually opposing. The only place those can be oppositional is in the realm of rhetoric but not fact.

Our founders did not write that 'We hold these Truths to be self-evident, that all US Persons are created equal.'

We have to call mass surveillance mass surveillance. We can't let governments around the world redefine, and sort of weasel their way out of it by saying this is bulk collection.

In liberal societies we don't typically require citizens to rearrange their activities, their lives, the way they go about their business, to make it easy for the police to do their work.

It's really hard to take that step-not only do I believe in something, I believe in it enough that I'm willing to set my own life on fire and burn it to the ground.

I believe that when [senator Ron] Wyden and [senator Mark] Udall asked about the scale of this, they [the NSA] said it did not have the tools to provide an answer. We do have the tools and I have maps showing where people have been scrutinised most. We collect more digital communications from America than we do from the Russians.

They are intent on making every conversation and every form of behaviour in the world known to them.
