Many of us can remember a time when children were allowed to roam freely and unaccompanied by adults. It would have been intrusive for a parent to insert themselves into the lives of their children while they were playing, fighting, and resolving differences with other kids. (We refer to that as "free range children" these days.) The world is considered less safe today, although I'm not sure that is really the case. Children walking home from school without adult supervision is not something limited to places like Copenhagen. You can see the same sort of thing in New York City with children riding the subways after school without an adult chaperon. Kind of incredible children in the suburbs, where things are considered safer, are not allowed by their parents to walk to school with friends.
