CNN anchor Alisyn Camerota posited that “mental illness” may “lead to violence” while discussing a recent shooting in Dallas, a problematic framing of mental health issues that feeds false stigmas and ignores research debunking the notion of a direct causal link between mental health and violence. 

James Boulware attacked Dallas police headquarters with a gun before fleeing in an armored van on June 13. He was killed after a brief standoff with police, and his relatives are now saying Boulware had a history of mental health issues. 

Discussing the Dallas shooting on June 15, CNN's Alisyn Camerota implied there may be a direct connection between mental health issues and violence, asking her guest, “Do you see this as just another sad case of someone's mental illness leading to violence?” Citing the Aurora, CO and Newtown, CT shootings, Camerota then said, “We hate to give the impression that mental illness leads to violence, but does mental illness lead to violence, like in these cases?”  

But there is no evidence of a direct connection between mental health and violence -- A 2013 report from The Consortium for Risk-Based Firearm Policy explained how most people with mental health issues are “more likely to be victims than perpetrators of violence,” noting that only about 4 percent of violence in the United states “is attributable to mental illness.”:  

Many recent gun violence prevention policy discussions have assumed a direct causal connection between mental illness and violence. The research evidence suggests that violence has many interacting causes, and that mental illness alone very rarely causes violence.

[...]

Importantly, only a very small proportion of violence in the United States - about 4% - is attributable to mental illness. 

According to the Consortium, only under very limited circumstances does a link exist between “individuals with serious mental illness” and violence: 

Most people with serious mental illness - which includes conditions such as schizophrenia and bipolar disorder - are never violent toward others, and are in fact more likely to be victims than perpetrators of violence. However, research suggests that small subgroups of individuals with serious mental illness, at certain times, such as the period surrounding a psychiatric hospitalization or the first episode of psychosis, are at elevated risk of violence. In addition, the population with serious mental illness experiences high rates of co-occurring substance use, an important risk factor for violent behavior in the general population.

Out of the Consortium report grew the Gun Violence Restraining Order proposal, which would allow family members of a “person who is at an elevated risk of harm to self and/or others to petition a court to temporarily remove firearms from that individual.” 

Speculation like Camerota's feeds into the misperception that people with mental health issues are inherently violent, a myth about which the public is already misinformed. This misunderstanding is often fueled by entertainment and news media that mostly portray such people as dangerous, leading to widespread stigma and discrimination.
