Pervasive surveillance has already caused shifts in behavior that wouldn't exist without them. For one thing, teenage fights are filmed by bystanders and replayed/posted on the Internet. Pictures of women in compromised positions (children even) are passed around schools. Cyberbullying (even though I hate that term) is easier and more anonymous because of these tools.
If you're the victim, it can feel as if you are fighting the entire world.
THAT's why I think someone would be well within their rights to take swift action to halt something like that in its tracks.
BTW, I'm certain it's the reason why police risk the backlash associated with taking cameras away from third-parties vs. having their actions armchair-quarterbacked by legions of second-guessers.
