So hey, I'm shoving this camera in your face so ten years from now you can be turned down for a job because you might do today that can be taken out of context. But why all the hate?
Dunno. Personally, I'm all for personal responsibility -- if I do something in public today that'd get me turned down for a job in ten years, that's 100% my own damned fault.
Ubiquitous cameras help keep honest people honest, and help get people who aren't honest caught. If some asshat runs me off the road on my (very, very well-lit) bicycle, I damned well want there to be a record showing (1) their license plate, and (2) me being my usual, exceedingly law-abiding, conscientious self. If someone breaks into my condo? Record. If someone picks a fight, and I need to show that self-defense was justified? Record. If someone was merely an asshat? Well, that's fair game too.
Keep in mind, too, that if everyone is getting the same kind of record built up about them, then small infractions aren't such a big thing. If everyone is a drunk asshat at a party every so often, or does a bit of political baiting, then evidence of that happening doesn't really matter -- as long as it's equal-opportunity public record, then employers &c. will be forced to compromise on hiring people whose indiscretions aren't so bad.
So -- if shoving a camera in your face is something you hate, maybe you should think long and hard about the way you behave in public.
