Has the best response I've seen so far to the "if you have nothing to hide, you have nothing to fear from surveillance" argument. A statement so silly that I simply cannot take it seriously. Greenwald points out that those who say this don't really believe it and go to great effort to be sure that they are not subject to it.
But those who do claim loudly that they are "nice" people with nothing to hide (or who simply do not have the means to create their own personal privacy bubble) make themselves into small, submissive subservient citizens. And that is deadly for democracy. As J.C. Scott put it in Two Cheers for Anarchism:
The implications of a life lived largely in subservience for the quality of citizenship in a democracy are also ominous. Is it reasonable to expect someone whose waking life is almost completely lived in subservience and who has acquired the habits of survival and self-preservation in such settings to suddenly become, in a town meeting, a courageous, independent-thinking, risk-taking model of individual sovereignty?
