The principle is that you should be able to casually document what you see in public, but you should not be able to intrude on the privacy of others.

Emphasis on casual, IMO. It is perfectly reasonable to decide that past norms which evolved in the absence of large scale computing power, digital cameras, and interconnected everything do not translate to the right to extrapolate freedom of casual observation into computer-assisted stalking.
