While I was at Provo Canyon School, one girl was standing (this was part of their penal system- for even the smallest infractions, such as having a wrinkle in your bedsheet, the child is made to stand for hours at a time, staring straight ahead, and starting over if caught moving their eyes around).
This girl stood for so long, she passed out, fell on her face, and broke her jaw, which had to be wired shut. I think she was a ward of the state of California.
We all continue to stand after that, with warnings "You better not lock your knees". They blamed this girl for her injury, saying she had locked her knees "on purpose".
I think the only way to have this place further investigated and maybe shut down is to KEEP TALKING. Continue contacting the authorities and lawmakers. Continue reaching out to survivors, friends & parnents, and the public.
