Science has identified common thread in school shootings (Opinion)
Understandably, we will hear a call to action in response to the shooting that left two young people dead at Saugus High School.
One political tribe will extend its thoughts and prayers and the other will demand sensible gun control.
In a matter of days, the rhetoric and, sadly, the memory of the event, will slip from the headlines. At least until it happens again.
The problem of mass shootings is not simple. An actual solution will not be simple either, but we can mitigate the threat by analyzing the commonality in mass shooters.
Consider that most elected officials and every corporation of consequence is protected by the employment of multidisciplinary teams trained in threat assessment.
These teams analyze behaviors such as threats posted on social media or those conveyed to third parties. These teams rely not on political talking points, but on scientifically validated behavioral analysis.
Yet inexplicably, in most jurisdictions, our children are not protected by this approach. This needs to change.
Criminologists Jillian Peterson and James Densley have been seeking data-driven prevention strategies.
Their research has looked at all mass shootings involving four or more deaths since 1966, and all shootings in workplaces, schools, and places of worship shootings since 1999. Their data reveal four comm
onalities among perpetrators of these mass shooters:
First, these mass shooters had early childhood trauma and exposure to violence at an early age.
Second, practically every mass shooter they studied had reached an identifiable crisis point in the weeks or months leading up to the shooting.
Third, most of the shooters had studied the actions of other shooters and sought validation for their motives.
Fourth, the shooters all had the means to carry out their plans.
For example, in 80 percent of school shootings, perpetrators got their weapons from family members.
Similarly, the Secret Service National Threat Assessment Center released its 2019 annual report this month analyzing mass shooters for commonality.
The findings showed that two-thirds had a history of mental health symptoms, including depression, suicidal tendencies or psychosis.
Nearly all had a significant life stressor within five years and made threatening communications. Three-fourths elicited concern from others prior to the attack. Research by the FBI finds the same commonalities.
Despite this, the media and many politicians seem to view each mass shooter as unique. They are not.
Their focus ignores the commonalities and instead centers on the identification of the individual’s motive.
These actors and their narrative, be it INCEL, white nationalism, religious extremism or ideology, should be viewed as pieces of a larger puzzle.
Rather than staring at the individual actor trying to understand him, we need to examine them in the broader context for commonality with other attackers.
The Secret Service National Threat Assessment Center, the FBI, and criminologists such as Peterson and Densley know that we can save lives by identifying and managing threats in a coordinated, behavior focused, multi-disciplinary approach.
The science informs us that regardless of the narrative or motive, in nearly every instance other persons knew some details of a planned attack.
We need a coordinated system of information gathering, including anonymous reporting, as well as public awareness of the need to say something when people become aware of concerning behavior.
Every regional jurisdiction must possess a multidisciplinary threat management plan to analyze concerning behaviors. These teams must use behavior driven standardized criteria based on science.
Recognizing the commonality with childhood trauma, these teams must make certain that children receive evidence based services.
Some ideas put forward by Peterson and Densley to prevent future mass shootings: potential shooting sites can be made less accessible with visible security measures such as metal detectors and police officers.
They suggest weapons need to be better controlled, through age restrictions, permit-to-purchase licensing, universal background checks, safe storage campaigns and red-flag laws, measures that help control firearm access for vulnerable individuals or people in crisis.
Peterson and Densley also suggest that we try to make it more difficult for potential perpetrators to find validation for their planned actions by pointing to media campaigns like #nonotoriety which seeks to starve perpetrators of the oxygen of publicity and by looking at how we consume, produce and distribute violent content on media and social media.
The crisis of mass shootings and school shootings is complex. But there also are common threads.
Our solutions should be grounded in science not hyperbole.
