or, even better,
... I am under no legal, dare I even say ethical, obligation to turn my gaze upon seeing you experiencing a revealing wardrobe malfunction, though it may be considered polite and kind to do so.
I agree - but I see a HUGE difference between "seeing someone experiencing a revealing wardrobe malfunction" (especially with non-recording eyes) and deliberately placing a camera in an unusual and revealing viewpoint.
My take on it is very simple: (A) If it's visible in public, it's fair game.
But this is *not* visible in public from a normal human viewing angle. And the typical case that makes news is someone having a camera on a shoe, or suspended from their hand (in a bag or briefcase, for example), to get an angle that a human would only get lying on the floor - not a typical posture in public.
By the way, how do you feel about Google Earth vans putting their cameras on top of a van higher than the typical fence? Or someone floating a camera drone outside your bedroom window? It's the same argument, from above or below: Yes, you're in public, but we have a convention of viewpoint being within a normal range, and if you go out of your way to get an improper viewpoint you're a "Peeping Tom".
Your good nature will bring you unbounded happiness.
