They don't mention how these policies impact one very important group in the article: the victims of these attacks.

And their alternative solution is "restorative justice." Would you trust "restorative justice" to handle the situation properly if someone physically attacked you? School is supposed to be a safe place to learn, not a place to get beaten up by other children. This seems like it has the same arguments and problems as attempts to "abolish the police" in other circumstances.

Some of the incidents mentioned here are horrifying but so are many incidents where children have experienced serious abuse at school at the hands of their peers. It sounds like there's some improvement that can be made here but we need the discussion to include all stakeholders, and we need to fully recognize that student victims are not an acceptable sacrifice in the aim of improving outcomes for violent students.
