The school, and every other student.

That moves the problem elsewhere, it doesn't solve it.

I've mentioned this above, but I know of a new pupil in one of my local schools who has recently seriously injured another pupil and attempted to strangle one of the teachers (she had to take time off work due to stress).

He is only seven and has just been expelled from another school.

Surprisingly hard to expel a child, particularly in the more privileged schools … far more satisfying from the perspective of an educator if they can address the issue.
