It's not just the police in Britain who fail to act- British doctors refused to section a man whose parents told them was becoming increasingly irrational and violent. A man who had been diagnosed as paranoid schizophrenic. Only 36 hours after the parents' appeal to doctors, their son-
"stabbed his mother from the back, headbutted her and then stabbed her nine more times, eventually cutting her throat."
The young man in question had apparently become more and more unstable for a period of eighteen months before the attack.
