Coincidentally today, the BBC is carrying an article about the Nottingham attacker (linked earlier) and the many apparent failing of MH services. He killed two men and one woman. It's not always the case that children are the victims. Nor that everyone with MH issues is dangerous to others.
I expect we'll hear more about the motivation of this attacker idc.
Right now, I have immense sympathy for the mother and daughter; and huge admiration for Abdullah, the other two men who helped restrain the attacker, and the other staff who administered first aid
