The preventable tragedy in Lewiston, Maine, is yet another reminder that horrific mass shootings are far too common — and a uniquely American problem. Once again, a weapon built for battle has stolen 18 people’s lives, injured 13 others, and traumatized an entire town. In mass shootings that dominate headlines, in the almost daily gun violence that haunts some of our most vulnerable communities, in the relentless toll of gun suicide, the United States suffers every day from gun violence. Other countries don’t live like this, and we don’t have to live like this either. Sensible gun laws can — and in some states do — prevent these mass shootings before they happen. But in order to get there, we cannot be led astray by scapegoating mental illness.
Scapegoating mental illness is especially ineffective in preventing mass shootings.
While the assailant in Lewiston reportedly had previous psychiatric hospitalizations, it is a mistake to simply blame the shooter’s mental illness for this attack and move on. Despite the consistent focus on mental illness as a major cause of gun violence, only about 4% of violent incidents can be attributed solely to mental illness. Irresponsibly promoting the myth that links mental illness with dangerousness perpetuates stigmas that create even more barriers to mental health care. Someone with a mental illness is far more likely to be a victim of violence than a perpetrator.
Further, scapegoating mental illness is especially ineffective at preventing mass shootings. Less than 5% of mass shooters would have met the qualifications to bar them from owning or purchasing a firearm based on severe mental illness. To the point: The U.S. is not the only country where a significant proportion of the population lives with mental illness, but we are the only country that regularly endures mass shootings — and that is due to our easy access to firearms.
Research shows there is a better way to intervene and keep firearms away from people likely to inflict tragedies like the one in Lewiston.
Instead of maintaining a potentially counterproductive focus on mental health diagnoses, we need to look at behavioral risk factors. Public health experts have known for decades that the greatest indicator of future acts of violence are past acts of violence. Couple this with factors like drug and alcohol misuse, repeated interactions with law enforcement, and other risky behaviors, and we get an understanding of indicators for potential violence that are more predictive than a diagnosis of mental illness alone. This is about looking at risk and following epidemiology, not perpetuating stigma.
