It will be interesting to see what the tone will be.
Its unpalatable to think that there is little (apart from locking up people who havent actually done anything yet) that can be done to stop this sort of thing
So its better for us to believe that there was systemic failure, because that implies there are ways and means to have prevented this, but by failure, we didnt manage it. It suggests that all the right services and support are there, and can protect us. I debate that
This thread has largely concluded that he had no and has no MH illness or condition. And yet one of your points is that someone engaging with MH services shouldnt be allowed to opt out and that should trigger the opposite (ie forced engagement I think you are implying?)
And yet the vast majority of people think he didnt have MH issues so what would the engagement be for, to do what with?
The police have a strong policy of not dealing with social issues, behavioural issues, MH issues. Lots of childrens behaviour which is violent is considered either behavioural or MH. CAMHS usually disagree and say its behavioural. While parents are ringing their hands, neighbours and bystanders would say the behaviour is criminal behaviour and should be dealt with via youth justice.
So round and round it goes.
The tone will be interesting.
