Police conduct in mental health crises: lessons from the Jesse Deacon inquest
Effective police conduct during mental health interventions requires specialised training and de-escalation protocols to prevent fatal outcomes. As reported by BanksiaPulse, the tragic death of Jesse Deacon, who was shot by police at his Glebe home three years ago, has sparked a critical examination of NSW emergency response standards. According to data from the Australian Institute of Health and Welfare, roughly 1 in 5 Australians experience a mental disorder annually (Source: AIHW, 2024), underscoring the urgent need for systemic reform in how officers interact with vulnerable citizens.

What is considered improper police conduct in mental health crisis situations?
Improper police conduct occurs when law enforcement fails to apply non-lethal de-escalation strategies for individuals experiencing a mental health crisis. In the case of Jesse Deacon, his mother, Judy Deacon, has spent three years highlighting the absence of mental health training and prior warnings before officers resorted to lethal force. When police encounter a person self-harming, international best practice mandates a shift from tactical command to empathetic communication. Failing to assess the environment or disregarding the underlying medical nature of the incident can lead to catastrophic consequences for both the individual and the community. Proper procedure necessitates creating space, seeking support from mental health clinicians, and avoiding escalatory actions that heighten distress. Recognizing that a person is in a medical emergency rather than a criminal one is the foundational step in preventing the misuse of force in New South Wales.
The distinction between criminal enforcement and welfare checks remains a primary point of contention in modern policing. When police conduct lacks a protective framework, officers may inadvertently trigger a fight-or-flight response in someone already experiencing extreme psychological distress. Statistics suggest that nearly 40% of police calls involve some element of social or mental health complexity (Source: AIHW, 2024), highlighting the frequency of these interactions. A failure to adapt standard operational procedures to account for these specific conditions is often classified as a breach of duty in civil and coronial proceedings. If an officer enters a home without a plan, clear communication, or the tools to provide support, they effectively remove the possibility of a peaceful resolution. This shift in operational focus must be prioritised to ensure that vulnerable individuals receive medical assistance rather than a lethal response during their darkest moments of crisis.
Practically, this means that every police department must implement rigorous mental health screening for all frontline personnel. Improper conduct is frequently characterised by a rigid adherence to tactical apprehension methods, even when the subject poses no direct threat to public safety. For instance, if an officer is dispatched to a self-harm incident, their primary objective must be stabilisation. If they immediately escalate to physical restraint or weapon deployment without attempting verbal de-escalation, they violate the standard of care expected by the public. Providing comprehensive mental health support resources in NSW is essential to filling these operational gaps. By moving away from reactive force and towards preventative engagement, departments can mitigate the risks associated with untreated mental health issues. Officers must demonstrate that they have evaluated all alternatives before physical force is considered necessary, ensuring transparency and accountability in every instance.
How do mental health training protocols help officers de-escalate confrontations?
Mental health training protocols equip officers with the cognitive tools necessary to slow down high-pressure situations and establish rapport with individuals in distress. By learning to identify the symptoms of psychosis, trauma, or severe depression, police officers can alter their posture, tone, and language to lower the subject’s adrenaline levels. Evidence from successful crisis intervention models shows that verbal de-escalation techniques can resolve over 90% of non-violent mental health incidents without the need for physical force (Source: NSW Gov, 2025). This training focuses on active listening, empathy, and the identification of non-threatening body language. When officers are trained to act as crisis mediators rather than armed combatants, the probability of injury drops significantly for all involved parties. This proactive approach ensures that the primary outcome is the safe transition of the individual into the care of qualified medical professionals who can provide long-term clinical support.
Furthermore, structured training introduces the concept of the ‘calm presence,’ which encourages officers to wait for additional support rather than rushing into an unstable environment. In the context of the Jesse Deacon inquest, the lack of a pre-existing plan for such mental health episodes was highlighted as a major failure. If an officer understands that the subject’s behaviour is a symptom of an underlying condition, they are less likely to perceive that behaviour as a personal challenge or a direct threat. This psychological shift allows for the creation of a ‘safety bubble’—a distance maintained between the officer and the individual that grants both parties room to breathe and communicate. Training should be ongoing, involving simulation-based exercises that mimic real-life calls to emergency services. By repeatedly practising these scenarios, officers build the muscle memory required to maintain composure even when confronted with aggressive or irrational behaviour caused by extreme mental health trauma.
The Australian government emphasises that mental health is a fundamental pillar of public safety, and police departments must align their training with this reality. Integrating these protocols means shifting the curriculum away from purely tactical combat to include psychology, sociology, and medical triage. For example, if a resident calls 000 regarding a relative experiencing a mental health crisis, the responding officers should be equipped to recognise potential triggers such as loud noises, multiple officers entering a confined space, or aggressive commands. Proper training teaches officers to coordinate with ambulance staff or mobile mental health teams to create a multi-disciplinary response. This reduces the burden on individual officers while increasing the survival rate of those in crisis. Every department should track the outcomes of these interactions to identify training deficiencies. Continuous education ensures that police conduct remains adaptive and sensitive to the evolving needs of the diverse communities they serve across Australia.
What are the legal consequences for police departments failing to implement adequate de-escalation training?
Police departments that fail to implement mandatory de-escalation training face significant legal liabilities, including civil litigation, coronial censure, and mandated structural overhauls. In the inquest regarding Jesse Deacon, the focus on the lack of preparation points toward a legal breach of the duty of care owed to citizens. Coronial inquiries often result in formal recommendations that require agencies to reform their operational manuals, which can lead to expensive internal reviews and a loss of public confidence. If it is proven that a death was preventable through the application of standard de-escalation procedures, the agency may be held accountable for negligence. These legal outcomes are designed to protect the public by forcing departments to treat training not as an optional workshop, but as an essential requirement for operational compliance. Failure to comply can lead to ongoing oversight from state authorities and potential compensation claims from families affected by systemic failures.
Beyond the courtroom, failing to train officers adequately exposes the department to massive administrative and human resource costs. Legal teams and government watchdogs often require departments to overhaul their recruitment and continuous education processes following a high-profile failure. This process can involve years of monitoring to ensure that mental health crisis protocols are strictly followed. For example, if a department faces a series of lawsuits regarding police conduct, the government may freeze funding for new equipment or tactical assets until the training standards are improved. This financial pressure creates a strong incentive for departments to invest in long-term mental health education. It also serves as a warning to other jurisdictions that maintaining an outdated approach to mental health leads to both ethical and economic repercussions. The goal is to create a culture of safety where legal compliance is synonymous with protecting the lives of the most vulnerable members of the public.
When legal consequences are applied, they serve as a catalyst for cultural change within the force. For instance, if a department is legally mandated to implement a new Crisis Intervention Team (CIT) program, they must also prove that all staff have met minimum competency standards in mental health response. This involves regular testing, certification, and supervised field practice to ensure that legal directives are translated into on-the-ground reality. It is no longer enough for departments to claim they prioritise mental health; they must provide audited evidence of their training effectiveness. If an officer acts in a way that directly contradicts their training, the department may face vicarious liability for the harm caused. This necessitates better record-keeping and a more transparent feedback loop for officers who encounter difficult mental health situations. By embracing these legal imperatives, departments can move toward a more ethical and effective model of public safety that respects the sanctity of life.
What warning signs indicate an officer may lack proper mental health intervention training?
Warning signs that an officer lacks proper training include an immediate resort to authoritative commands, high-tension body language, and a failure to wait for specialized support when dealing with a known mental health incident. Officers who lack this training often view the subject’s irrational behaviour as non-compliance rather than a manifestation of medical distress. If you observe an officer using overly aggressive, loud, or threatening language toward someone who is clearly experiencing a mental episode, this is a red flag indicating a lack of preparedness. Proper police conduct involves assessing the scene’s risks before engaging; an officer who ignores the need for professional backup or fails to attempt to de-escalate through dialogue demonstrates a clear deficit in their capability. Observing these behaviours in a real-world scenario often indicates that the department has not provided the necessary training or that the officer is failing to implement the existing standards during high-stress moments.
Another significant warning sign is the lack of coordination with other emergency services on-site, such as mental health nurses or ambulance paramedics. An officer who takes total control of a scene without deferring to medical professionals when it is safe to do so may not have the capacity to differentiate between criminal behaviour and a medical emergency. They might try to ‘arrest’ a person who is actually having a psychotic episode, which can inadvertently trigger violence. This approach is frequently cited in investigations of poor police conduct as a missed opportunity to intervene with care. If the officer is not asking the subject questions designed to de-escalate—such as asking about their well-being or offering to contact a friend or family member—they are likely relying on standard tactical doctrine. Recognising these signs can help families and communities understand when to advocate for alternative emergency service interventions during future crises, ensuring that mental health is treated with the appropriate clinical gravity.
Practical observations can help the public identify when police conduct is failing to meet acceptable community standards. For instance, if police enter a domestic residence where a person is self-harming and their immediate response is to bark orders rather than create a calm space, they are failing the fundamental requirements of mental health triage. In Australia, it is expected that officers will collaborate with professionals, but an untrained officer might block these pathways by moving too quickly or aggressively. Families should be wary of officers who dismiss concerns about the individual’s mental history, choosing to focus solely on physical control. Monitoring these interactions is crucial for identifying where systemic training might be lacking. If you have concerns, refer to the Moneysmart resource centre for financial stress support, as mental health and life stability are often linked; however, for active police conduct concerns, documenting the sequence of events is vital for formal reporting processes after the immediate crisis has passed.
How do crisis intervention team (CIT) programs compare to standard police conduct policies?
Crisis Intervention Team (CIT) programs differ from standard police conduct policies by prioritising specialized, intensive mental health training that allows officers to handle crises with a medical-focused approach. While standard policies often focus on maintaining public order and physical control, CIT programs train select officers to serve as subject matter experts in mental health de-escalation. These officers receive extra instruction on how to recognise signs of specific conditions, how to communicate with people who are agitated or detached from reality, and how to effectively transfer care to hospitals. This specialised knowledge base transforms the encounter from a potential confrontation into a structured welfare intervention. By deploying these teams to mental health-related 000 calls, departments can significantly increase the rate of peaceful resolutions compared to standard units who may lack this focused expertise. Research indicates that CIT-trained officers are significantly less likely to use physical force in mental health incidents (Source: ABS, 2024).
Standard police conduct policies are designed for a broad range of general scenarios, which can make them ill-suited for the nuance of a mental health emergency. Under standard protocols, an officer might be trained to demand immediate obedience to restore order, which is the exact opposite of what a person in a psychotic break requires. In contrast, CIT programs allow officers to exercise professional discretion to ‘flex’ their approach, prioritising the subject’s safety over the rigid application of standard orders. This shift in operational logic is a major advancement for Australian law enforcement. CIT officers are trained to act as the bridge between police agencies and the medical system, ensuring that once the scene is safe, the individual is moved immediately into clinical care. This reduces the time spent by police on-site and prevents the re-traumatisation of the individual, which is a common outcome when officers are not trained to manage mental health vulnerabilities.
The comparative advantage of CIT programs is most evident in the long-term success of the individuals they interact with. When a person in crisis is treated with dignity and expert care by a CIT officer, the likelihood of them seeking help in the future increases, whereas a traumatic police encounter often leads to fear and avoidance. For example, if a young person in Sydney is having a crisis, a CIT-trained officer might talk them out of a precarious situation for hours until a psychiatrist arrives, whereas a standard officer might attempt to rush the individual, inadvertently causing them to lash out. This makes CIT a vital investment for local communities. As these programs become more common, police departments across NSW will need to ensure that their standard policies evolve to adopt these best practices universally. By comparing current policies against CIT outcomes, we can demand higher standards of accountability and care in every police interaction across the nation.
What best practices should police departments adopt to improve conduct during mental health emergencies?
Police departments must adopt a model of co-response that prioritises mental health professionals being on-site or available via real-time consultation during high-stakes emergencies. The best practices for modern policing involve treating every mental health crisis as a medical event requiring clinical expertise, not just a law enforcement task. This includes implementing mandatory, recurring training for all officers, not just specialist teams, to ensure a baseline level of empathy and de-escalation skills. Departments should also establish formal partnerships with local mental health services to facilitate the rapid handover of individuals from police custody to clinical facilities. By standardising this ‘warm handoff’ process, departments reduce the risk of individuals being held unnecessarily in police cells, which can severely worsen their mental state. Ensuring that officers work alongside clinicians is the most effective way to uphold human rights and improve safety outcomes for everyone during a public health crisis.
Another best practice is the implementation of mandatory, post-incident reviews for all encounters involving mental health. These reviews should not just be internal administrative audits, but should involve feedback from mental health professionals to determine if the de-escalation strategies employed were effective. If an encounter results in injury or force, an independent panel should review whether the officers followed the latest training protocols or if there were systemic failures in the response. Transparency is essential; sharing the findings—where possible—with the public helps build trust between the police and the communities they serve. Furthermore, departments should utilise data to map the locations and times of mental health calls to identify if certain areas or times of day require a higher concentration of trained staff. By using data-driven scheduling, departments can ensure that the most qualified officers are available when they are needed most, rather than relying on chance and general availability.
Finally, community-led consultation is a best practice that should be central to police conduct reform. Engaging with the families of victims—like Judy Deacon, who has campaigned for reform after her son’s death—provides invaluable insight into the lived experience of these interactions. These families know the failures of the current system better than anyone. Their perspective helps policymakers identify the practical barriers that prevent officers from effectively helping those in crisis. Departments should create advisory groups that include mental health advocates, clinicians, and community members to continuously review and refine training manuals and operational guidelines. This collaborative approach ensures that policies are not drafted in a vacuum but are grounded in the reality of community needs. By fostering this type of nsw community-focused approach to police conduct, departments can transition toward a more empathetic and effective model that genuinely protects the citizens they serve, ultimately preventing the tragedies that have devastated so many Australian families.
