The law needs to catch up. We were comfortable with the idea that a person is not entitled to privacy in public when we knew that the observation would simply be from other humans in close enough proximity to see us. But in the day when we can inexpensively put cameras everwhere, take pictures of everything you do, and effortlessly distribute it to the entire world ... maybe the idea of privacy, or at least anonymity, needs to be revisited. I'm not sure exactly where the compromise point is, though. We want photographers to be able to snap pictures of a crowd, and it is infeasible to gain permission of every member of the crowd. We may not want photographers taking close up shots of individuals, who will do things that they may not want photographed even when they're in public.
