I hadn't thought that angle (yet). It brings to mind Bill Gates' book (The Way Forward?) from the 1990s where he said something to the effect that each of us would carry around a personal computing devices that records everything we do, and that this would be good if you were falsely accused of a crime, but bad if you had committed it.
I'm not sure what my point is, except that Gates has been thinking about this exact issue for decades.
