For what it is worth, I have not been questioned by a police officer for something I did or did not do. I do think that me having the mindset that I am always being watched in public helps me better police myself, so I think the more obvious and ever-present version might instill a similar feeling in others.
At the same time, I can see that having this footage available has a slippery-slope effect when it comes to privacy and authoritarian control. However, this issue of groups of people using technology to control or manipulate others is fundamentally a non-technical issue to me because these people exist irrespective of that technology's existence.
