The removal of cameras is a similar principle. If you remove the constant view of something, people will tend to return to negative or selfish behaviors. Before they had cameras in the mirrors of dressing rooms, for instance, people used them to steal merchandise and, in some circumstances, worse things such as rape. The flipside is that now you have someone watching you while you change. If you're not a thief, rapist, or a drug-dealer, they're not interested in you.
Cameras are an invasion of privacy, though fighting for absolute privacy seems to be futile today.
Rather, it seems our efforts would be best focused on erosion of privacy and personal sovereignty as pertains to activities that harm none or very few. I am unbelievably boring. My apologies to Scott Adams and the quote that I butchered, but that's my view on it. Look at your life. A public space is public.
