It seems to me that this point of view is becoming less and less common - now that most people have cameras in their pocket, we're starting to lose the intellectual distinction between "seeing" and "recording", and without that it's hard to have any nuance about what you are and aren't allowed to do with video you captured in public. Eventually, there will be new social norms about it, but for now, you must expect that "in public" means "potentially seen by any person on Earth"
