Actually, the UN standards do support the use of restraints. What it does not support is the use of restraints for punishment and it does not support the use of chains or straight metal bars. Because of equipment issues, which we tried to reconcile through my time there, the only resource these two facilities had was the use of chains. That's why it was cited as an incident, because the UN standards prohibit the use of chains.
