Only parents would have access to surveillance records. Children often do not like stuff their parents make them do, and their power over them, this would be one more thing, with great benefits.
> Why the hell not?
Because they are children, they do not have full responsibility for their actions, and they are more vulnerable to abuse, and protecting their safety is more important than protecting their privacy. I want to keep the status quo, where children are protected, and adults have rights. The way stuff is going, we're all getting more like children with one parent called Big Brother.
> Would you be happy if there was a camera constantly watching you as you jerked off as a kid?
That is not what I'm suggesting. I'm talking about public spaces (including online) where adults are present. If the kid wants to jerk off, or two or more kids want to make love, they can go home or use some private space like a bathroom.
