I still find it a bit unsatisfying... but then again, all doesn't have to be tied up neatly. I feel badly for the school especially - even though it sounds as though it was not all that wonderful to begin with having such a weak principal. And as for Professor Hearst: it matters not how wonderful a teacher he was, in that he was also a pedophile, he may be found "guilty" of murder for which he has been framed, but he is still guilty for killing the souls of how many victims! I don't have one bit of sympathy for him.
