As far as government goes, I'm for total tranparency in its every workings. They exist at our pleasure (or so I was raised to beleive, not sure I buy that anymore), therefore, anything they do, as representatives of the people, is open to scrutiny by the people.
As for some idiot standing on the sidewalk taking pictures of me and my family? I think, at some point, that could become harassment and I'd deal with that eventually, one way or the other. Freedom means they're free to do it and you're free to handle it as you see fit. Works for me.
