DaMoshe,
Thanks for your response.
I do know, however, that the kid wasn’t just tossed out. The school found an appropriate place for him, and worked with the new school to get him settled in. That is how it should be handled.
I agree.
Are you sure that the yeshivos mentioned in your OP didn’t do anything similar?
I hope that this child you mentioned thrives in his new environment, but suppose as a thought experiment he became violent again at the new school and needed to get moved to a third school, and then a fourth, and a fifth, and a sixth, and then to a Yeshiva in a different town? And some years later, that child with a violent past, now a man managing a business, tells a frum man in a resort dining hall that he was kicked out of 7 yeshivos that couldn’t handle him, and he will never be Orthodox because of that. Should that frum man imply that your school’s hanhala will face hellfire for the way he handled the violent kid?
