There was another instance of a 10 year old girl bringing a steak knife into school to eat her lunch of steak leftovers.
Some teachers saw this, so they confiscated the knife, and then naturally called the cops, who arrived and naturally arrested her for possession of a weapon on school grounds, and naturally charged her with a felony.
Fortunately, sanity eventually prevailed, and the charges were dropped.

All because of @$#% stupid zero tolerance policies enacted by @$#% stupid people. They're a bit like the brilliant three strikes laws, which can sentence someone to life in prison for shoplifting.

And naturally, the Supreme Court refused to overturn the sentence. Way to go, guys.
