1. Fair point. I think I had in mind a future where these devices were in such common use that
any bystander could be assumed to be wearing one. That might lead to greater targeting of all bystanders, but at some point I suspect criminals (or other privacy seekers) would just adapt and factor "avoid bystanders" into their plans in order to settle at about the same level of violence they do today (rather than routinely attacking every bystander they see). This may be over-optimistic.
2. I find it to be an intriguing idea, but one that does admittedly scare the bejesus out of me. Unfortunately, I consider it all too probable that near-ubiquitous camera surveillance is in our future whether we like it or not, and in that scenario I'd vastly prefer for individuals to have their own recordings as well rather than blindly trust that the governments and/or corporations running the other cameras will always act with my best interests at heart.
