Chris, I have to wonder at the 'soft' description you give of restraint. I have not ever seen or herd it described as anything less than very painful; of significant duration; and often for Extremely minor actions on the students part.
Many students, my own son included, speak of the stress and anxiety caused by hearing other students being restrained - b/c they cry and scream and beg for it to stop.
My son was restrained while in OP for requesting a bathroom break. Yes, he kept asking after they said no (a non working choice, apparently) on the third request, he was put under restraint.
He has not mentioned if they at any point let him go to the restroom. He has not mentioned if he pissed himself. A lot of kids do mentioned how frequently hapless students wet themselves due to not being allowed to take a restroom break. I suppose this might explain why so many complain of the OP room smelling of urine. But, I don't know if my son suffered this degradation or not. If so, its one of the things he is keeping to himself. In any case, Why do they refuse a kid a restroom break? And How can the request amount to the need for restraint?
I find this unexceptable. Cruel even. Purposefully humiliating.
Please don't try to tell me nothing like this ever happened. My son has no reason what so ever to lie about it; The many other boys I've talked to, have no reason what so ever, to lie to me about it. It did happen and frenquently; to many kids.
Do you really think restraint of this nature is exceptable?
