I'm wondering out loud, what would the repercussions, from a behavioral standpoint be, if everyone wore something like google glass. Would almost everyone turn into "law"-abiding persons? Would that even be desirable? I'm sure drunk, or otherwise in an altered state of mind, people would still act quite unruly. But what would the effect be on regular people? Would it be mostly chilling, or a kind of werdly pleasant place where people act nice because getting away with "unlawful behavior" would be much more difficult? Gone would be some adolescent rites of passage...
It could become the ultimate case of people policing each other (in the sinister neighborhood watch committees sense --ala Cuba, Vietnam, etc.)
In modern America we have this outlandish idea that it is a fine thing to "be ourselves" to the limits of the law out in public.
More traditional etiquettes include the concept of what happens in public following different rules from what happens in private. "I do not care as long as he does not scare the horses in the street" is the old saying. Just do not cause other people hassles, please. (This has a dark aspect, too, overlooking domestic violence hidden behind closed doors, but that is not important to the question on hand.)
If we move to a world where your public behavior might be displayed to your family and co-workers, I think that will be a good thing overall. If you want to misbehave, please keep it in private locales.
I like Heinlein's use of this in "For Us, The Living", he breaks out the Public and Private spheres and addresses how anything done in the private sphere is effectively heavily tabooed to inquire about, and could even become a criminal penalty.
Politicians having a much smaller private sphere of course.
