A US high school punishes students that fail to smile while walking between classes.

Students have a ready-made answer when pressed to talk about why they don't smile: "It's because you are harassing me."

They could also try putting on exaggerated phony smiles.

The discussion of a bullying incident refers to a "school resource officer", which is a bureaucratic name for a thug that is likely to send your child to prison for some minor matter. The last thing you need in school is a thug that can arrest students.
