It's strange how a society supposedly obsessed with safety nonetheless thinks normal to place a child in such an environment, then do everything to prevent them from defending themselves. It's a prison environment, only the inmates did nothing to deserve being there.
The problem could be that kids don't interact much with people outside their age group. They have no reference point of how adults behave. It becomes a sort of Lord of the Flies world.
Our society isn't really obsessed with safety. It's obsessed with being safe from rare, sensational dangers.
If we really cared about safety, we'd focus less on airport security and "stranger danger", and more on getting people to wear seatbelts and never drive while intoxicated. Statistically, automobile accidents are by far the leading cause of accidental death in the US.
