publick space is publick space. it isn't a publick space BECAUSE it has cctv in it, it is a publick space WITH cctv in it. the cctv is only important because you know you're being filmed anyway: this tends to undermine any legalistic objection you would have to having your picture taken by someone else. if you have no realistick expectation of privacy - and let's face it, a business space founded on the principle that anyone can enter doesn't offer a realistick expectation of privacy - again you can't do more than huff and puff and froth about having your picture taken. maybe this isn't right. maybe it's downright wrong. but that's the way it is.
