if it were true, it would happen all over the planer, but it doesn't
a decade ago I would defend the USA and say "you have to take into account they have 300 million people, that is why it looks like they have a lot of mass shooters, in average they must be normal"
but I was wrong, the USA is special in that regard.
school shooters are a part of american culture, like cheerleaders.
school shootings are caused not by weapons or autism, but by american school culture.
that truth is upsetting for americans, american culture can't be a bad harmful thing, so they deflect blaming weapons or videogames. Switzerland has both weapons and germanic autism, but kids don't shoot their classmates.
