Seeing as how the girl’s self-injurious behavior centers around smashing her head through gypsum wallboard, I’m not sure a poured concrete wall is the best option. The facility she is in now has padding on the walls for her safety. If she could stay there as an adult, it would be wonderful, but government bureaucracies seem to think age cures Autism.
I thought we were talking about the big dude that beat up a teacher’s aide ...
Self harming folks need the straitjacket and the padded cell.
