This particular situation feels a bit cruel given it’s about disabled children, but I have a controversial aside to explore: I feel like there is a place for corporal punishment in schools in the more general case. My classrooms had disrespectful and disruptive brats who dragged down the learning experience for everyone. It’s clear their parents didn’t do their job and schools could have used better deterrents to correct their behavior, or at least to protect the needs of other children. I’m not defining what the right techniques are or what the limits are, but am claiming that a free for all with weak punishments like detention is not the right solution.
