We can't help everyone. It's naïve to think we can, 100% of the time, help all people.
Even the most socially progressive system on the planet will have people slipping through the cracks- we have to be able to deal with that eventuality too.
True but at the moment we have a particularly poor record of helping people with mental illness. This guy didn't slip through the cracks, he was totally ignored along with many others who are struggling.
There's absolutely no evidence he had mental illness, and you do harm to people with mental illness when you incorrectly link violent behaviour to mental illness.
More important is his time in prison - where most UK terrorists were radicalised - and if you were saying that UK prisons don't rehabilitate I'd agree.
