I think there's a bit of a miscommunication that happens when people discuss 'privacy' in this area. With the advent of unprecedented recording and computational resources, comes a new type of privacy, which I would call here (and is used in other places) the 'right to be forgotten'. I absolutely think that you shouldn't expect privacy in the sense of "no-one should be looking at me", but I think you should be able to be able to assume that information about what happens in public is not kept indefinitely, and only used to track people who have been suspected of a crime (and had authorisation given for surveillance). While lots of things don't generally change 'on a computer', the scale of some things change, and when the scale of what's possible changes that can and should encourage debate.
