Yo, parent of child victimized by zero-tolerance here. My kid did not commit suicide, so I figure I got off light, but believe me it was no fun at all.
The only thing that could be better than denying funding to zero-tolerance schools would be to publicly execute every single politician who ever voted for such evil nonsense and publicly flog every citizen that ever voted for said politicians with barbed wire.
If you haven't been through the mill, I sincerely doubt you can truly understand the horrors it grinds. For one thing, these policies have caused many caring school administrators to retire rather than be part of such a system, and thus it selects over time for child-hating sadists in the school principal office.
Think about it; what sort of person will consider it "all in a day's work" to enforce a policy that is proven to harm children and serve absolutely no educational purpose?
