Over the past 50 years, our schools have become sites of increased criminalization of young people—a disturbing fact that is even truer for poor Black and Latino communities. Today, police officers assigned to patrol schools can legally use physical force on students, arrest and handcuff them, and bring the full weight of the criminal justice system to bear on kids who are simply misbehaving. The primary role of police in schools is to enforce criminal laws, and virtually every violation of a school rule can be considered a criminal act if viewed through this police-first lens.
