you are pretty much screwed.
And the rat-bastard will make damned sure every teacher thinks he or she is the test case.
Not to mention that having even a bogus child sex-abuse charge that was summarily dismissed is just not cool on a teacher's resume. And by "not cool" I mean career is over.
Judges may scold him, but he won't be penalized in any way, and he gets to be a wingnut hero. Rat-bastard. Playing silly games with people's lives, and he fucking knows it.
Any other field, you deliberately screw up your work in order to intimidate people, you get arrested or sued or sanctioned by your profession. Public official, specifically exempt from any and all penalties.
