On a winter evening in Taipei, random violence erupted across two of the city’s busiest metro stations. Within minutes, lives were lost, dozens were injured, and a familiar cycle followed: shock, fear, calls for more security, and questions about public safety. But for those of us in health care, this should not be framed as a failure of policing alone. It should be recognized for what it truly is: a failure of the health system long before the first blade was drawn.
Random violence does not emerge from nowhere. It is rarely sudden, and almost never isolated. It is often the final visible collapse of invisible systems (untreated mental illness, social isolation, fragmented care, and repeated missed opportunities for early intervention). Metro stations like Taipei Main Station and Zhongshan Station are not just transit hubs. They are the nervous systems of a city. When violence erupts there, it reflects more than individual pathology; it reveals collective strain. Crowding, anonymity, pressure, and disconnection converge. When the system fails, the breakdown happens where the signals are most concentrated.
After every such incident, hospitals become the final safety net. Emergency departments absorb the chaos. Surgeons operate through the night. Intensive care units stretch their limits. Mental health professionals are asked to intervene, but only after irreversible harm has occurred. Health care is repeatedly positioned as a reactive system, tasked with repair but denied a role in prevention.
This pattern should concern clinicians. We are trained to recognize warning signs, risk factors, and deterioration trajectories. Yet when those same principles apply outside hospital walls (in communities, transit systems, and public spaces), we pretend they are beyond the scope of medicine. They are not. Mental health is not solely the domain of psychiatry. It begins in primary care, community outreach, continuity of treatment, and early identification of those drifting out of care. Every untreated psychotic episode, every interrupted follow-up, every patient lost between systems is a clinical failure, even if the consequences manifest far from the clinic.
It is uncomfortable to ask these questions after acts of violence. We fear that acknowledging systemic gaps may sound like justification. It is not. Accountability and prevention are not opposites. They are inseparable. We must ask: Where was this person months before the attack? Were there encounters with the health system that went nowhere? Was treatment inaccessible, discontinued, or fragmented? Did anyone notice, and if they did, did the system allow them to act?
Public transport violence is not only a security issue. It is a population health signal. When mental distress accumulates without pathways for care, it does not disappear. It erupts. As clinicians, we cannot limit our responsibility to the moment a patient arrives bleeding at the emergency department door. If we truly believe in prevention, we must advocate for mental health systems that function before crisis, not after headlines.
Hospitals should not be the last line of defense. They should be part of a continuum that never allows despair to reach this point. When random violence breaks out in a metro station, it is not just a tragedy of public safety. It is a reminder that medicine, when disconnected from community and continuity, arrives too late.

He is affiliated with the Home Health Care Charity Association and maintains a professional presence on Facebook, where he shares updates on research and community work. Kuo helps operate a day-care center for older adults, working closely with families, nurses, and community physicians. His research and practical efforts focus on reducing administrative strain on clinicians, strengthening continuity and quality of elder care, and developing sustainable service models through data, technology, and cross-disciplinary collaboration. He is particularly interested in how emerging AI tools can support aging clinical workforces, enhance care delivery, and build greater trust between health systems and the public.
