Public schools are owned and operated by the state, but that doesn't mean their policies are managed and enforced at a state level.

I agree that this policy is a good one, but I don't think should be enforced by the school. I'm not an educator, but if I were I don't think I'd be happy about forfeiting my policy control to a government official.

How would a law like this even be enforced? Are teachers expected to take legal action against their students?

Educators in public schools are government officials.

Laws and policies prohibiting objects in schools are common, and typically enforced through confiscation when the offending item is observed; whether after that the item is forefeited, returned to parents, or has some other disposition , and whether there is subsequently legal proceeding or additional penalty, varies considerably but is generally peripheral to primary enforcement.
