Where's the sense in that?

Did everyone hear about the little girl in Florida who was removed from school by police for bringing a knife to school in her lunchbox? Read the News article if you haven't.

I understand in this day and age that seeing a knife in the school can cause concern but I still can't help but think that there was serious lack of good judgement shown here. Every article I found specifically stated that she did not threaten anyone or brandish the knife. I noticed the police said that it was school policy that they be called because the knife was considered a weapon. What makes a steak knife a weapon? Wouldn't it be at the moment that it was used in a threatening way? Which it was not. All she wanted to do with it was cut the steak that she had brought for her lunch. Why couldn't the knife have just been taken from her, her parents called and she talked to about why you don't bring steak knives to school?

I don't see any common sense reason this child should have been transported from school in the back of a police car and now have the threat of felony weapons charges hanging over her head. Were the teachers hands tied by rules or did they just see what they perceived to be a weapon and go overboard? I'm not sure I'd be happy with either answer if I was that child's mother.
