The upshot of all this was that if the young man had received help,this may not have happened.
The young man was adopted,and he'd confided in his parents,GP,Psychiatrist and Psychologist,that he didn't " feel right ". That was when the GP removed his anti-psychotic medication.
Apparently,the man's father had asked " why the frig ( his words ) did the doctor take him off his medication when he'd said he felt like stabbing people ?"
The diagnosis was bi-polar disorder,which the man's father had said he was being over-medicated for as he appeared morose for most of the time.
Obviously in Australia they don't treat bi-polar as a disease of the mind.
