@izzythepush,
The mental health issue really is complete bollocks.
Most shooters are perfectly sane.
It's a societal issue, guns are seen as a way of solving problems, gaining notoriety, being remembered.
The Columbine shooters have been researched and referenced by so many that followed.
Thi9s is not mental health, it's about having a short fuse.
That's the case everywhere, but it's such a problem in America because of the ridiculous gun laws.
Over here people with a short fuse end up in front of the magistrate for thumping someone.
