Oh, come on, having horrible judgement is the whole point of being a kid. The process of growing up and becoming an adult is all about learning and acquiring good judgement. How can you expect people to gain the judgement that comes with experience without allowing them to gain that experience by trying things, some of which will turn out to be mistakes? How are they supposed to know which things are going to be the mistakes without trying some of them and thereby learning the patterns?
I once did more or less the same thing as Ms Wilmot did, and you bet I did it during school, and I didn't even bother to tell anyone about my intentions first! I set up an apparatus under one of the fume hoods in the back of the chemistry lab, dissolved a bunch of aluminum, captured the hydrogen in a balloon, and then blew the whole thing up. It made a hell of a big bang, shattered a bunch of glassware, and startled the hell out of my lab-mates. Bad judgement? Well, yeah. Duh. But I didn't actually hurt anyone, and I sure learned something from the experience, and I'll bet that all my classmates learned something from it too, without having to deal with the embarrassment and clean-up that landed on my shoulders for being the nitwit who tried it.
Just imagine how fucked I'd have been if I'd had to face felony charges after that. My whole life might have been different, my whole software engineering career derailed before it had even started. What a stupid waste that would have been. What a stupid waste it is going to be for all of us if this idiotic treatment of Ms Wilmot is allowed to stand.
