But Ssri use is on the rise globally and you don't see this rise in violence against groups of people in other (stable) countries. UK. Iceland has one of the highest uses, where are all the Icelandic shootings?

Almost certainly though tied to the govt/prison/medical systems (which in many cases of psychiatric disorders are all involved) failing everyone. And culture. And ease of access to guns by people who in retrospect clearly shouldn't have them.
