In the immediate aftermath of the Tumbler Ridge tragedy, the public narrative is already hardening into a familiar, unhelpful script. Carmine Starnino and Tracy Vaillancourt, writing for The Walrus, dismantle this reflex before it fully takes hold, arguing that our rush to blame mental illness or specific identity markers is not just wrong, but dangerous. They offer a stark, neuroscience-backed alternative: that violence is often a predictable outcome of specific developmental trajectories and, most critically, the easy availability of weapons.
The Myth of the "Sick" Shooter
The piece begins by confronting the chaos of early reporting, where the pressure to inform often leads to the permanent staining of innocent lives. The Walrus writes, "That mistake won't simply disappear—it's now part of the internet forever. That's deeply frustrating." This observation is crucial; it highlights how the speed of the information age exacerbates the harm of mass violence, turning speculation into a digital scarlet letter before facts are even verified.
The authors then pivot to the most persistent and damaging misconception: the conflation of mental illness with violence. Vaillancourt, a leading researcher on the neuroscience of aggression, makes it clear that this is a convenient lie we tell ourselves to avoid harder truths. "Mental health is such an easy boogeyman, it's become such a convenient explanation, that it allows us to avoid harder questions," she argues. The core of their argument is that we are using a medical diagnosis as a moral scapegoat. By attributing the shooting to a "broken mind," society absolves itself of the need to examine social structures, family dynamics, or policy failures.
Critics might note that dismissing mental health concerns entirely could lead to under-funding for crisis intervention. However, the authors are careful to distinguish between the vast majority of people with mental health struggles and the tiny fraction who commit violence, noting that "most violent crimes, including mass shootings, are committed by people who are not mentally ill."
The Anatomy of Aggression
Moving beyond the boogeyman, The Walrus delves into the actual drivers of aggression, weaving in a nuanced view of human behavior that rejects the idea of innate goodness. The authors explain that while humans are generally pro-social, we also possess a capacity for hostility that is triggered by specific conditions. Vaillancourt outlines a complex mix of genetic heritability, neurobiological differences, and environmental factors. She points out that "some people are psychopaths... Their brains look quite different from non-psychopathic individuals," while others are simply impulsive and dysregulated.
This distinction is vital for risk assessment. The article suggests that we are looking for the wrong signals. Instead of waiting for a diagnosis, we should be watching for "lifelong persistence of aggression." The Walrus notes that a small minority of individuals are aggressive across their lifespan, often dropping out of school and disappearing from institutional tracking systems. "These life-course-persistent aggressors cause a disproportionate amount of harm—probably around 85 percent of the violence we're talking about," the piece states. This reframing shifts the focus from a sudden "snap" to a long, observable trajectory that institutions frequently miss.

The Role of Identity and Contagion
The coverage also tackles the fraught issue of the shooter's transgender identity. The authors warn against the temptation to use this fact as a shorthand for explanation, noting that it risks further vilifying an already marginalized community. "The fact that we're mixing mental illness with violence is also going to happen with trans identity," Vaillancourt explains. This is a sharp critique of how media narratives often seek a "reason" in identity rather than in behavior or access.
Furthermore, the piece addresses the "contagion effect," not as a universal phenomenon, but as a specific risk for a vulnerable slice of the population. The Walrus describes how certain individuals become "true-crime experts of school shootings," obsessing over past attacks and trading details in online communities. This is not about general mental health; it is about a specific subculture of imitation. As the authors put it, "They become experts... They know all about those who came before them." This aligns with historical data on school violence, where a significant portion of perpetrators have documented histories of fixating on previous attacks, a pattern seen in incidents ranging from Columbine to the 2018 Parkland tragedy.
The Gun as the Deciding Factor
Perhaps the most damning part of the analysis is the focus on access to firearms. The authors argue that while we struggle to predict who will snap, we know exactly what turns a threat into a massacre: the presence of a gun. Vaillancourt draws a sharp contrast between Canada and the United States, noting that the difference in mass shooting frequency is not due to cultural differences in aggression, but to "access to guns." The Walrus writes, "If I say I'm going to shoot up the school, and there's five guns in the house, we better be looking into this."
The article highlights a critical failure in the Tumbler Ridge case: firearms had been removed from the residence, yet they were returned. The authors question who signed off on this decision, implying a systemic failure to recognize the lethality of the threat. "There's no debate there. No negotiation," Vaillancourt insists regarding the link between means and risk. This is the piece's most actionable insight: we cannot rely solely on behavioral prediction when the means of destruction are so readily available.
Critics might argue that stricter gun laws infringe on rights or that returning firearms is a standard legal process. Yet, the authors counter that when a credible threat exists, the calculus changes. "If you're telling you, I'm going to do it, and they have credible means to do it, then it elevates the risk," they state, emphasizing that the presence of weapons transforms a behavioral issue into an imminent public safety crisis.
Bottom Line
Starnino and Vaillancourt provide a necessary corrective to the sensationalism that usually follows such tragedies, grounding the discussion in neuroscience and data rather than speculation. Their strongest argument is that our obsession with the "why" of the shooter's identity distracts us from the "how" of the violence: the availability of unregistered weapons. The piece's biggest vulnerability lies in the difficulty of implementing the proposed solutions, as identifying "life-course-persistent" aggressors requires a level of data integration and social intervention that currently does not exist. Readers should watch for how local authorities respond to the question of why weapons were returned, as this will reveal whether the system is capable of learning from this failure or if it is destined to repeat the script.
