Yep. That's exactly the kind of rationalization I'm talking about. You don't know any of that for sure for each machine camera and certainly don't know what a random person will do with a taken video.
But I think it also has to do with the fact that at least with him people actually have someone to be mad about. As opposed to their usual mode of surveillance where they are being filmed by a 'security' camera (hey, it's security people! nevermind if it doesn't actually make anything any safer) operated and owned probably by their boss or someone who they are not on equal grounds with.
It makes me kind of sad.
