Huh? They went to a Chippendales review performed in a private establishment attended only by people who were there voluntarily. How does that qualify as "in public?"
It was not illegal, but it was immoral. You can and should expect public officials to practice some level of morality especially school teachers.
Sure, and I would say there is serious disagreement as to whether or not a Chippendales show counts as immorality. I certainly don't think so.
And if the morals of the county in which this guy is superintendent have degraded to the same level, this guy will keep his job and might even be congratulated.
