Despite widespread propaganda, people with mental illnesses only commit 3-4% of all violent acts within the U.S in any given year. Mental health conditions are more strongly associated with suicide, not homicide. Restricting access to guns for those with mental health issues does not take into account those who already own guns and develop mental health conditions over their lifetime. Researchers say, given the climate of blame, people with severe mental health disorders may be dissuaded from seeking treatment.
"Routinely blaming mass shootings on mental illness is unfounded and stigmatizing. Research has shown that only a very small percentage of violent acts are committed by people who are diagnosed with, or in treatment for, mental illness."
