The injustice against black people at the hands of police doesn’t start with adults on the street. It starts with black children in school, often during the school discipline or suspension process. They are systematically suspended, expelled, and arrested in school at rates far higher than white children, for the same behaviors, especially when the underlying violation requires a subjective determination, such as “disrespect,” “disruption,” or “disorderly conduct.”
Students have due process rights when they are suspended, expelled or disciplined. There are additional protections for students with IEPs (Individual Education Programs for students with disabilities) and sometimes section 504 plans.
