I always found the prevalence of law enforcement and criminal law within US schools odd in and of itself.

Where I grew up, you'd get detention/expelled, in the US you get charged with a crime and an actual police officer will put handcuffs on little kids, little kids will go to court, and get a criminal record until 21.

The whole criminal justice system in the US is incredibly unusual from the perspective of an outsider.

For example, you literally put innocent people into a situation where they need to plead guilty for a shorter time in jail or to save money. Such as traffic courts where the ticket is less than the "court costs" (if you fight it). Or a plea deal of time served (Vs. spending longer in jail awaiting trial).
