Why not whip the teacher when the pupil misbehaves?
This is a generation weaned on Watergate and there is no presumption of innocence and no presumption of good intentions. Instead there is a presumption that without relentless scrutiny the government will misbehave.
Every child senses with all the horse sense that's in him that any parent is angry inside when children misbehave and they dread more the anger that is rarely or never expressed openly wondering how awful it might be.
It seems that when you get to a certain age you almost give yourself permission to misbehave and say what you think. People allow it with very old people.
