I think this is a bad example, because one of the YouTube video comments are right (to me): "The point you are trying to make is lost when you film people in a private place! That actually is not allowed." This experiment is sort of flawed since he does just budge into private rooms/settings and everything without permission. Also, I suspect he has a decent size camera (by some of the reactions), and not something discrete like Google Glass. I wonder if people would have reacted any differently if he was just doing this with Google Glass and it wasn't as obvious he had a big camera on them. He would have probably been treated just like anyone else interrupting a class or private setting. Also, they wouldn't have mentioned the video, but the results would have been the same.

I would like to see this experiment done in a public settings, or this same experiment but with a much more discrete camera.
