You do have privacy in public. Both the de jure "reasonable expectation of privacy" and the de facto privacies of anonymity, free association, and predictable rules of social engagement.

Does not protect your exposed face

>the de facto privacies of anonymity, free association, and predictable rules of social engagement

Are outdated illusions with no basis in fact

Well, I seem to have no trouble practicing all of those, so I know they are based on fact. Perhaps you don't actually understand what I'm talking about? Or maybe your experiences differ. Either way, telling me the things that that I personally do are not being done is... not an argument.

>>the de jure "reasonable expectation of privacy" > Does not protect your exposed face

Yeah, that's why it is "reasonable expectations" not "absolute enforcement."

In other words, as long as you are unaware of the surveillance, you are happy to pretend it doesn't exist? So where's the problem? Just don't click on links like the OP.
