The Phase 1 report from the Southport Inquiry is out has found the attack "could and should have been prevented".
It was "highly likely" it wouldn't have happened if agencies and the killer's own parents had actually done their jobs over the years. Catastrophic failures everywhere - police, mental health services, social services, schools - all passing the buck, losing information and refusing to take ownership of the risk this boy posed.
But the bit that really jumped out at me is this: a "misunderstanding of autism" meant his violent, dangerous behaviour was wrongly blamed on his autism spectrum disorder.
Instead of treating the clear warning signs of murderous intent as the serious red flags they were, everyone just shrugged and said "it's his autism" and did nothing. No proper risk assessment, no real intervention, no one stepping up.
Neurodiversity / mental health services were so terrified of "stigmatising" or "criminalising" autism that they ended up enabling actual danger to everyone else.
The parents also apparently let weapons be delivered to the house and didn't report crucial things in the days before.
