That's a good point. At the same time I'm not sure what level of privacy people expect in a public bathroom. Anything you don't want someone seeing should be done within a stall. At best I would consider a public restroom as having increased privacy, but by no means being private.

I understand that's probably a hard sell though, as people have some idea that it's verboten to record in the open space of a public restroom (it's definitely frowned upon, but I think police cameras are a good exception to have, especially if they need to enter the restroom to perform their jobs because that's where a disturbance is), so whatever gets more camera use in the end I'm on board with, from a practical standpoint.
