Do you think teachers trained to investigate and properly handle evidence? Because if they don’t, then the evidence isn’t admissible in court, or maybe they decide to kick out the wrong student on suspicions.
Every day, administrators already have to investigate occurrences at school and choose appropriate disciplinary paths forward.
Coursework in legal matters is part of educational leadership/administration programs and is a focus of professional development, in part because districts are incentivized to reduce litigation costs.
I share your apparent concern that districts, etc, screw up discipline often and unjust outcomes occur. However, doing nothing isn't an option, and I don't think punting more of school discipline to the police is likely to improve outcomes.
