Other countries have 'nutters, poor parenting, drug abuse, pissed off people"... right? If not, then why is USA so insane and out of control?
Easy access to guns for the poor parents (leading to poor children... shoot teachers, etc), drugs abusers, etc increases likelyhood that guns will be in the mix of outcomes. That is a "true issue". Many like to say it is a "mental health" issue, but mental health issues cross all countries and cultures. On top of that, the pro gun lobby also cuts funds for mental health. In Texas they repealed a law that banned mentally ill from owning a gun...
It's very simple: if you don't have a gun, you can't shoot someone
Gun deaths are number 1 cause of children's deaths in USA. Why there and no where else?
