My kids would be removed from that school so fast that the scene would look like a cartoon with the streaks going across the page.
I would then see a lawyer & see what kind of lawsuit I could mount against the school & the teachers.
Not to sue for money against the school- but to get a peermanent cease & desist ruling.
As for the teacher—I would sue them out of business.
Ditto...this is f-cking outrageous. I am boiling right now.
