Film Maker Laura Poitras responds as follows to those who say (in reaction to revelations regarding the surveillance state) “I have nothing to hide”:

If someone says, “I have nothing to hide,” does that mean they want a camera in their bedroom? Or that they want their computer to be a two-way camera, feeding information into a government office? Do they want a switch that can be flipped so that your phone becomes a microphone streaming your personal conversations to the government? Most people who make the argument “I have nothing to hide” don’t fully understand the technical capabilities that the government has. They are vast. All these devices that we carry around with us can, at the flip of a switch, be turned against us. Our most intimate moments, our beings, ourselves… It can become an Orwellian nightmare where all these tools that we surround ourselves with can beam our whole life to people sitting in some secret government facility.
It’s not that the government is necessarily interested, it’s that there’s nothing to stop them, legally or technologically. And a person would never know when it’s happening. They won’t tell you because it’s all a secret. I have a Gmail account, and I assume that everything is being handed over, probably in real time, to the government, and I think I should have a right to know that that’s happening. There are no technical constraints to this becoming a full surveillance state. And we hardly have any oversight, and any laws that exist are all happening in secret.
