Jon,

You are aware of course that you have no expectation of privacy in public. If someone pulls their cell phone out and takes a video of you, there is no requirement on their part to get consent from you. The best thing you could do in that situation is leave. Same goes here. Nobody is forcing you to go downtown. You could avoid all places with security cameras if that was your prerogative. Of course that would leave very few places for you to go already. But that is the price you pay when you live in a self imposed prison of paranoia. But advocating against a reasonable measure that could make downtown safe again, a place where women are afraid to walk alone, which is shameful; because you have a fear of some Orwellian conspiracy strikes me as being a little self involved.
