If crazy is genetic, then the level should be the same everywhere.

in the USA as much as sucks... "treatment" is more accesible. No other country has so much kids on amphetamines... or anti-psychotics even. So why don't we get higher level of violence in countries where less people is on heavy duty legal drugs? why are such incidents rare in other countries? there's countries with guns (switzerland for example), but these incidents just don't happen. Could it be a culture that somehow glamorizes violence?

And actually it's this attitude that makes people go untreated... stigma much, everybody?
