Mental Illness, Violent Crime, and the Legal Profession: Why Better Education Matters

The Lindsay Clancy trial has brought renewed public attention to one of the most difficult questions at the intersection of mental health and criminal law: What happens when serious mental illness and violent crime intersect? It is certainly not the first time this has happened, and it likely won’t be the last. We see it used as a defense in court, and we see it blamed for mass shootings. All the talk and all the headlines have the danger of fueling more stigma, which is why education is particularly important. Especially in the legal profession.

The Clancy case has generated passionate reactions, with some members of the public emphasizing Clancy’s alleged postpartum psychosis and others focusing on the horrific consequences of the deaths of her three children. Yet for legal professionals the question is not simply whether someone was mentally ill. It is whether the evidence demonstrates that a mental illness affected the person’s capacity in a way that is legally relevant to criminal responsibility. That distinction is essential to a fair justice system.

Cases involving mental illness can be particularly challenging because public understanding of psychiatric conditions often comes from movies, news coverage, and highly publicized criminal cases rather than from experts and mental health professionals. That often creates an unfortunate and inaccurate association between mental illness and violence. The reality is considerably more complicated. Most people living with mental illness are not violent, and mental illness by itself does not establish that someone is dangerous or incapable of making decisions. Indeed, people with mental illness are more likely to be victims, not perpetrators. 

At the same time, severe psychiatric conditions can, in certain circumstances, substantially affect a person’s perception, judgment, or understanding of reality. The legal system has to be capable of considering both realities without allowing either one to dominate the analysis, and without sacrificing justice for both victims of violent crimes and those living with severe mental illness. And this is where mental health education for legal professionals can make a meaningful difference. 

Attorneys, judges, prosecutors, defense counsel, probation professionals, and other members of the justice system do not need to become mental health clinicians. They do, however, benefit from understanding basic psychiatric concepts, the limitations of psychiatric diagnoses, how symptoms can present differently among individuals, and the difference between a specific diagnosis and functional impairment. In a case involving psychosis, for example, understanding what psychosis actually means, and what it does not mean, can help legal professionals evaluate expert testimony without relying on stereotypes or assumptions. In turn, this can help combat stigma in the jury room and move the criminal justice system towards more just outcomes. 

Judges have an especially important role. Judges routinely are required to make decisions about competency, about what criminal insanity test to apply, about sentencing, about evidentiary disputes, about mental health evaluations, and about the scope of expert testimony. Better mental health education can help judges identify when additional expertise may be necessary, ask more informed questions about psychiatric evidence, and recognize the difference between genuine clinical uncertainty and competing conclusions about the same evidence. It can also help courts avoid treating mental illness as either an automatic explanation for criminal conduct or an irrelevant excuse that should be disregarded.

That education ideally should extend beyond the courtroom. Prosecutors and defense attorneys should be equipped to recognize potential mental health issues early in a case and understand when specialized evaluation may be appropriate. This isn’t a stretch given that attorneys are already trained from their 1L year to focus on “issue spotting.” Attorneys also need to understand how language can shape perceptions. Describing a defendant as “crazy,” “unstable,” or “dangerous” may be rhetorically powerful, but those labels can obscure rather than clarify the actual legal and clinical questions. Similarly, describing every defendant with a psychiatric diagnosis as a victim of their illness can oversimplify complicated cases and minimize the experiences of victims and their families.

The Clancy trial ultimately belongs to the jury, and its outcome should be determined by the evidence and the applicable law, not by public opinion. But cases like this can provide an important lesson for the legal profession. Justice requires accountability, but accountability is most meaningful when the system understands the circumstances it is being asked to judge. Improving mental health education for legal professionals, including judges, is not about lowering standards or excusing criminal conduct. It is about giving the people responsible for applying those standards the knowledge necessary to do so fairly. It is about improving the system.

The broader goal should be a legal system capable of holding two ideas at the same time: mental illness should never be used as a shortcut for determining that someone is dangerous, and serious mental illness should never be dismissed simply because the conduct involved is horrifying. Victims deserve justice. Defendants deserve due process. Communities deserve safety. And all three are better served when the legal professionals responsible for those outcomes understand mental health well enough to distinguish evidence from stigma.
