Except the stories are exceedingly moralistic and make lots of points about right and wrong. Most of the time when the kids break the rules it's presented as a lesson in Doing Good, or at least Not So Bad Because These Are Good Kids. It's just that the moral system they suggest isn't, imo, functional at all. I think that's probably why people notice it.

It's basically a world where everybody believes that rules are things that apply to other people ("the bad guys") but nobody in the books, kids or adults, makes the connection between what they do themselves and what they rail at others for doing, or figure out that if they want justice for themselves they'd have to have a just system.
