The knife could have been taken from her by another student.
But, .....................The girl was arrested and transported to the Juvenile Assessment Center. is so far past the level of stupidity it is beyond words.
How about the school administrators take the knife away and explain to her it was a bad idea to bring a metal knife to school and give her a plastic knife to use.
OMG how much common sense does that take!!!!!!!!!!!!!!
A phone call to her parents to explain the situation would have sufficed
At least in schools around here, those plastic knives are just as verboten. Drawing a picture of a knife got a 3rd grader expelled. Best thing that could happen to him. After his parents fought it for a month in court, they stopped fighting it and started homeschooling.
