There should definitely be better trigger points added to healthcare and warnings to signify either errors of judgement or malice. My opinion of the management involved in this case is also very low. The parents also deserve justice with the failings in that area.
The mental health side of things should be taught in schools to let people know when things are abnormal. No one tells you that it is normal to have some of the syndromes that affect all of us in our daily lives. Without realising there is an issue, people can easily blow things up and create spirals that are hard to get out of. Mental health should not just be down to professionals, just like physical health having some awareness of good/bad can go a long way.
