Comment re: No right or expectation of privacy in public (Score 1) 63
I think the real shift began when computer processing power became great enough to make it feasible to analyze public video footage and index it for long-term storage. The idea you don't have an expectation of privacy in public always made sense to me. But it was intended to protect the rights of photographers and videographers, primarily. (You should be able to take a photo of your friend or family member in public, while random strangers mill about behind them, and not risk them filing a lawsuit against you for it.) If someone can see you and what you're wearing or doing in public, with the naked eye? Then they should be able to photograph it too. If you didn't want that to happen, then you shouldn't have gone out in public wearing or doing whatever it was.
Until recently though? Nobody thought photos or videos were providing people with any capabilities beyond keeping the captured content for a fairly long period of time and them having ability to view them or show them to others they knew, at will.
Now, it all extends to that captured information getting automatically data-mined/processed. Numerous aspects could be resold to interested parties, for all sorts of uses the subject of the photo or video never even imagined. Even the location and time can become part of a bigger goal of tracking one's travel habits. And contrary to what used to take place, a person being captured on video or photo is part of whole networks of cameras doing the data collection all over the geographic area. This is no longer about, say, the shop owner who wants to record his customers at the counter for security reasons. Now, that shop owner might buy a networked camera system for that purpose
