I would venture to say that literally no mass shootings, anywhere, ever, has been the result of "one crazy individual". Certainly none of the ones that make the news. There's always a community, however loosely defined, that radicalized them into thinking that murdering people is a viable solution. That level of descent into madness requires support.
One guy, with issues, two guns, 35 dead. Motivation was revenge and fame. No community required.
Your statement is just wrong.
He wasn’t radicalised, look it up. He was just an evil git that should never have been allowed near a gun.
This is an extremely narrow and naive view of the breadth of what humans can and will do.
You say that, and maybe it’s true. But it’s impossible for any New Zealander to know that given it’s a crime for any of them to read his manifesto.
However, you’ve linked to a process that educators can use to screen restricted films to their students.
I have little interest in how New Zealand is run, but if I did this would be a massive concern for me. For the interested parties, the details of his motives are incredibly important. That was the basis of new liberty-revoking legislation in New Zealand, and you think that New Zealanders should have no reasonable doubt that their politicians and press (who may or may not have even read it themselves) weren’t portraying it in a way that simply suited their own agendas? Believing that the government should be the only party allowed to interpret crucially important information is very undemocratic.

And even today a number of the shooters had specific targets in mind e.g. fellow students, teachers etc.
So driven more by individual rage and easy access to weapons.
