I saw plenty of tantrums in my day as a student long, long ago. The solution was simple and the problem solved in under 5 minutes. The kid got swatted, and shaped up. Then got swatted again by the parents at home. Today, the parents would sue, plain and simple. Who needs the aggravation?
I agree with you wholeheartedly, though in my ex’s case I think the officer made the right call by trying to scare the kid straight. Trying to push a teacher down the stairs is a major leap from a tantrum.
