Sometimes the vibes are wrong, and things go haywire. This is why zero tolerance policies have to be instituted in schools. That doesnt mean the general idea is wrong. Strict adherence to written law will always fail justice. The world is too nuanced and too fractal to handle every edge case well.

I seem to recall that zero-tolerance policies caused the expulsion of multiple Boy Scouts who were merely obeying the requirement that they always have a multifunction pocket tool with them (such as a Victorinox knife), and these caused the Scouts to rescind the rule.

"Zero tolerance" policies are a generally a tool of the Sith.

Every system fails sometimes. The only interesting question is whether it is systemic or not.
