This is from last week, but I just saw it.
While I'm not one of those "no snitch" people (the teachers are supposed to be In Charge, so why is it bad to tell them, oh, Bobby has a weapon?), but seriously - the kid has a knife, he's threatening someone... if the teacher isn't there now, they're not going to be there in time.
School board needs to have a sit down and decide exactly what lessons they're trying to teach. (And I hope there was a massive uproar that a kid who not only brought a knife to school, but actually threatened someone with it(!) was only suspended, and not, y'know, arrested?)
