My thought exactly. Why didn't the school call the mother rather than the police?
Having raised two boys on my own, if one of my kids had acted this way, I would have been sooooo embarrassed. I'd be apologizing profusely to the school and then kicking the kid's ass once I got him home. Nobody should have to tolerate behavior like this, especially not from a child. In the good old days, kids knew better than to act out for fear you'd be smacked and humiliated in front of the rest of the class. In this case, the kid's parents are the ones who should be handcuffed because they are cheating this kid by not providing proper discipline at home. One only has to look at her behavior in the classroom to know she displays such behavior at home. The kid definitely needs her bottom smacked, but she also needs to be confined to her room and her favorite toys, etc. denied her until she can show some respect for property and other people. If allowed to go on, she's going to end up having problems with the law.
