Nope. Try again. Ever heard of John Muhammad. The Ft Hood shootings wasn't a white guy. Neither was the Pulse Club or San Bernadino.
and not all of them were mentally ill either... (which is what i assume you were actually suggesting)
here's a summary of the findings from a 2016 paper on the subject of mental health and gun crime:
"Common Misperceptions
Mass shootings by people with serious mental illness represent the most significant relationship between gun violence and mental illness.
People with serious mental illness should be considered dangerous.
Gun laws focusing on people with mental illness or with a psychiatric diagnosis can effectively prevent mass shootings.
Gun laws focusing on people with mental illness or a psychiatric diagnosis are reasonable, even if they add to the stigma already associated with mental illness.
Evidence-Based Facts
Mass shootings by people with serious mental illness represent less than 1% of all yearly gun-related homicides. In contrast, deaths by suicide using firearms account for the majority of yearly gun-related deaths.
The overall contribution of people with serious mental illness to violent crimes is only about 3%. When these crimes are examined in detail, an even smaller percentage of them are found to involve firearms.
Laws intended to reduce gun violence that focus on a population representing less than 3% of all gun violence will be extremely low yield, ineffective, and wasteful of scarce resources. Perpetrators of mass shootings are unlikely to have a history of involuntary psychiatric hospitalization. Thus, databases intended to restrict access to guns and established by guns laws that broadly target people with mental illness will not capture this group of individuals.
Gun restriction laws focusing on people with mental illness perpetuate the myth that mental illness leads to violence, as well as the misperception that gun violence and mental illness are strongly linked. Stigma represents a major barrier to access and treatment of mental illness, which in turn increases the public health burden."
this is why i was being snarky
