I suppose that sounds good in theory, but it is neither reasonable nor possible to provide "continuous supervision" of a child who is determined to harass others, especially when that child is obviously not responding to normal motivational techniques. The simple reality is that the kid was on a collision course with what most of us rightly define as normality. The only way to stop that was to take him off the course, as his English teacher tried in vain to do. Meanwhile, the teachers who got praised were the ones BUYING him dresses, evidently beloved of administrators who thought of that (and bathroom squirming, I guess) as constitutionally protected.
I know of several cases in which that has been done. It can't be done in a feral school in which there are just too many discipline problems, but it can and should be done in any reasonably functional school with a limited number of predators. An assistant principal may require the bully to stay in the cafeteria during lunch and keep the brat in sight or even stay close for the little pest's entire lunch period, or they may have an instructional assistant walk him from one class to the next and then accompany him during lunch, but they can make the school safe from a limited number of kids with useless parents.
