1. Executive Summary
This report evaluates the effectiveness of framing gun violence as a public health crisis in driving legislative reforms, with comparative case studies from Australia, New Zealand, and the United States presented.
By redefining gun violence as a preventable epidemic, AOAV seeks to shift focus to the societal costs of gun violence – injuries, deaths, mental health impacts, and healthcare burdens – departing from traditional criminal justice narratives centered on crime and punishment (Rosenberg et al., 2017).
The cases of Australia and New Zealand are focused upon as they appear to highlight the transformative potential of public health narratives. Following the Port Arthur massacre in 1996, for instance, Australia implemented sweeping gun control reforms underpinned by a public health discourse that emphasized safety and prevention. This included a landmark National Firearms Agreement (NFA) and a government-funded buyback programme, resulting in significant declines in firearm-related homicides and suicides (Chapman et al., 2006). Similarly, New Zealand’s response to the Christchurch Mosque shootings in 2019 featured rapid reforms framed around community well-being and the prevention of mass casualty events, with strong public and political backing (Alpers, 2020).
In contrast, the United States primarily approaches gun violence through a criminal justice and constitutional rights lens, which has hindered the adoption of federal gun control measures. Despite the scale of firearm-related deaths and injuries, public health professionals are often excluded from national debates, limiting the influence of evidence-based strategies on policy-making (Kalesan et al., 2017).
The report concludes that public health framing offers measurable benefits in reducing gun violence and sustaining legislative change. For example, Australia has seen enduring declines in firearm deaths since the introduction of the NFA, and New Zealand’s reforms have removed high-risk firearms from circulation. These outcomes help remind us of the importance of public health advocacy in shaping effective gun control measures.
The report also examines the perspectives of key stakeholders, the strategic use of data in advocacy, and the broader implications of framing gun violence as a public health crisis.
2. Case Studies of Public Health Framing Successes
This section examines how public health framing has driven effective gun control reforms in Australia and New Zealand, highlighting the role of healthcare professionals, evidence-based advocacy, and legislative outcomes following high-profile mass shootings.
2.1 Australia: Port Arthur Massacre (1996)
The Port Arthur massacre in Tasmania, which claimed 35 lives and left 23 injured, stands as a pivotal moment in global gun control history.
The tragedy deeply shocked the Australian public and catalysed a transformative shift in how gun violence was framed and addressed. Central to this transformation was the adoption by those seeking gun reform in the wake of a terrible tragedy of a public health framework. This framework helped reframe gun violence as a preventable crisis rather than solely a matter of crime and punishment (Chapman et al., 2006).
The Australian Medical Association (AMA) and other health professionals played a key role in advocating for such reform, spotlighting the devastating toll of gun violence on individuals, families, and communities. They highlighted its broader societal consequences, including mental health trauma and the strain on Australia’s healthcare systems (Chapman et al., 2016).
In the wake of the massacre, and through the prism of the healthcare consequences of the violence, the Australian government enacted the National Firearms Agreement (NFA), one of the world’s most comprehensive gun control measures to date.
The NFA introduced uniform firearm laws nationwide, banning semi-automatic and automatic firearms, mandating firearm registration, and imposing strict licensing requirements (Alpers and Rossetti, 2021). A government-funded gun buyback programme also removed over 650,000 firearms from circulation (Chapman et al., 2016). These measures marked a significant departure from the previously fragmented approach to gun regulation in Australia.
The impact of these reforms has been profound. Within a decade of the NFA’s implementation, firearm homicides decreased by 59%, and firearm suicides fell by 65% (Chapman et al., 2006). Notably, these reductions were not offset by increases in other forms of violence, dispelling concerns that stricter gun laws might lead to a rise in alternative methods of harm.
As Alpers (2020) notes, “The Port Arthur massacre and subsequent reforms underline the power of the public health framework to galvanise political will and achieve substantial political change.”
2.2 New Zealand: Christchurch Shootings (2019)
In 2019, New Zealand experienced a similar watershed moment in its approach to gun violence following the terrible Christchurch Mosque shootings, which claimed 51 lives and injured 40 others. The tragedy spurred a nationwide reckoning, with public health framing central to the ensuing debate.
The discourse focused on protecting community health and safety, emphasising the role of firearms in enabling mass casualty events (NZ Ministry of Police, 2020). Prime Minister Jacinda Ardern became a prominent advocate for reform, stressing the societal impacts of gun violence and the need for preventative measures.
Notably, public health experts reinforced this narrative, highlighting the strain on emergency services, the mental health toll on survivors and first responders, and the broader implications for community well-being (Alpers, 2020). In response, the New Zealand government enacted comprehensive gun control reforms within weeks of the attack.
The new laws prohibited military-style semi-automatic weapons and high-capacity magazines, aimed at curbing access to firearms capable of mass harm (NZ Ministry of Police, 2020). A government-funded buyback programme also removed thousands of prohibited firearms from circulation (Alpers, 2020).
This swift action was partly put down by some commentators of the efficacy of public health framing in galvanising political will at work, something that helped secure public consensus for meaningful change. Although the long-term effects of these reforms on gun violence rates are still uncertain, early evidence indicates a significant reduction in the circulation of high-risk firearms.
Additionally, the reforms have heightened public awareness of gun safety and underlined the importance of preventative measures (NZ Ministry of Police, 2020). Public health professionals have hailed New Zealand’s approach as a model for other nations, offering, perhaps, proof of the power of framing gun violence as a preventable crisis affecting the health and safety of entire communities (Alpers, 2020).
These two examples from New Zealand and Australia help illustrate the transformative potential of public health framing in addressing gun violence. By focusing on the societal costs of firearm injuries and deaths, along with their mental health and community safety impacts, both nations successfully mobilised public and political will to enact comprehensive reforms. As Chapman et al. (2016) observe, “The success of these efforts underscores the importance of adopting a public health perspective in the global fight against gun violence.”
3. Comparison with Criminal Justice Framing
It seems, then, that how gun violence is framed – whether as a matter of criminal justice or as a public health crisis – may have implications for policy outcomes. So what about criminal justice approaches? These often emphasise punitive measures, focusing on perpetrators as inherently evil and focus on the legal repercussions of armed violence. This contrasts to public health framing that, as above, prioritises prevention, addressing the societal costs of gun violence, such as injuries, mental health impacts, and the strain on healthcare systems.
Here, then, the differences between public health and criminal justice framings of gun violence are analysed, focusing on the implications for policy effectiveness, with the United States serving as a case study of the limitations of the criminal justice approach.
3.1 The United States: Criminal Justice Lens
The United States stands in stark contrast to Australia and New Zealand, with gun violence predominantly framed through the lens of criminal justice and constitutional rights. Of note, the US is the only country in the world that, according to research by AOAV, has actively loosened its gun laws following a gun massacre, as opposed to tightening them.
Rather than addressing systemic factors such as healthcare costs, community trauma, or broader public health concerns, the debate in the US almost invariably centres on crime, punishment, and the Second Amendment (Kalesan et al., 2017). This charity argues that such framing severely restricts the scope and effectiveness of efforts to reduce gun violence.
The consequences seem evident: the U.S. has some of the highest rates of gun-related homicides and suicides among developed nations (CDC, 2023). Unlike Australia and New Zealand, where high-profile tragedies catalysed sweeping reforms, federal policymakers in the US have been unable to pass comparable measures, even after devastating incidents like the Sandy Hook Elementary School shooting in 2012 and the Parkland school shooting in 2018 (Rosenberg et al., 2017).
While attempts to adopt a public health perspective have made some headway at the state level, progress remains piecemeal. For instance, California has introduced gun violence restraining orders and allocated funding for firearm injury prevention research. Yet, as the CDC notes, “these measures remain fragmented and insufficient to address the scale of the problem” (CDC, 2023).
The persistent dominance of criminal justice framing continues to impede the development of comprehensive, evidence-based policies that prioritize prevention and community safety (Kalesan et al., 2017).
4. Effectiveness of Public Health Framing
This section evaluates the tangible benefits of public health approaches to gun violence, including measurable improvements in safety, reduced firearm deaths, and systemic prevention strategies, with examples from global contexts.
4.1 Measurable Improvements in Public Safety
The public health approach to gun violence reframes the issue as a preventable epidemic, shifting the focus from individual criminal acts to the broader societal impact of firearm-related injuries and deaths. This perspective emphasises that gun violence is not an inevitable part of life but rather a problem that can be addressed through evidence-based strategies, much like other public health challenges such as infectious diseases or road traffic accidents. By highlighting the significant toll gun violence takes on communities—including the loss of life, long-term physical and psychological harm, and the economic strain on healthcare systems—this approach underscores the urgency of preventative measures. Countries that have adopted this perspective have seen measurable improvements in public safety, demonstrating that a focus on prevention, education, and systemic intervention can effectively reduce the prevalence of gun violence and its devastating consequences.
4.2 Australia
Since the introduction of the National Firearms Agreement (NFA) in 1996, Australia has witnessed remarkable reductions in firearm-related deaths. Firearm homicides dropped by 59% in the decade following the implementation of the NFA, while firearm-related suicides declined by 65% over the same period (Chapman et al., 2006). These figures underscore the substantial impact of the reforms on reducing gun-related violence.
In addition to these reductions, the NFA effectively eliminated mass shootings in Australia. Before the agreement, the country experienced 11 mass shootings over a single decade. In the 20 years following the NFA’s introduction, no such incidents occurred (Alpers, 2021). By limiting the availability of firearms capable of mass harm, the reforms not only enhanced public safety but also strengthened public trust in legislative safety measures.
Concerns that stricter gun laws might lead to increases in other forms of violence, such as knife-related attacks, proved to be unfounded. Studies found no evidence of significant spikes in alternative forms of violence following the implementation of the NFA (Chapman et al., 2006). Together, these outcomes highlight the effectiveness of Australia’s comprehensive firearm legislation in reducing violence and fostering a safer society.
4.3 New Zealand
In response to the Christchurch mosque shootings in 2019, New Zealand acted swiftly to implement reforms aimed at reducing the availability of high-risk firearms. A government-funded buyback program led to the removal of over 56,000 prohibited firearms and 188,000 firearm parts from circulation (New Zealand Police, 2020). This initiative represented a significant step in curbing the presence of dangerous weapons within the community.
Early evidence suggests that these reforms have notably reduced the circulation of military-style semi-automatic weapons, contributing to improved public safety (New Zealand Police, 2020). The measures reflected a decisive approach to preventing the conditions that enable mass casualty events.
The tragedy also sparked nationwide conversations about gun safety, bringing greater public awareness to the role firearms play in acts of mass violence. This heightened awareness, combined with the legislative changes, underscored New Zealand’s commitment to prioritizing the safety and well-being of its citizens (Ardern, 2019).
4.4 Global Comparison
Countries that adopt public health narratives to address gun violence consistently achieve better outcomes than those relying on criminal justice framing. Nations that embrace public health approaches report significant declines in firearm-related deaths, highlighting the effectiveness of preventative strategies (WHO, 2018). By framing gun violence as a public health issue, these countries foster broader societal support for reforms, encouraging a collective effort to address the problem (Hemenway, 2017). Additionally, preventing gun-related injuries alleviates the economic burden on healthcare systems, leading to lower healthcare costs overall (Kalesan et al., 2014).
In contrast, countries such as the United States, where debates about gun violence remain centred on constitutional rights and criminal justice, continue to experience persistently high rates of firearm-related deaths and injuries. This stark disparity underscores the effectiveness of a public health framing in addressing gun violence and the limitations of relying solely on criminal justice perspectives (Fleegler et al., 2013).
5. Public and Political Support
The public health framing of gun violence highlights shared values like safety, community well-being, and prevention, making it a powerful tool for fostering broad public resonance and political momentum. By focusing on these universal concerns, this approach arguably transcends ideological divides and builds a compelling case for change. Its emphasis on prevention over punishment not only garners widespread public support but also provides a foundation for enduring legislative reforms. By aligning with societal priorities and addressing the collective impacts of gun violence, public health narratives have proven effective in driving meaningful and lasting policy change.
Here, then, the role of public health narratives in galvanising public opinion and political momentum is explored, with the report examining the ability to build consensus and enact durable reforms across ideological divides.
5.1 Public Engagement
Public health narratives resonate by appealing to a shared responsibility to protect vulnerable groups, such as children and communities impacted by violence. In Australia, the framing of the Port Arthur massacre as a preventable tragedy emphasised the avoidable nature of firearm-related injuries and deaths. This approach garnered widespread public backing for the National Firearms Agreement (NFA), including support from rural gun owners who might otherwise have opposed such reforms (Chapman, 2013).
5.2 Political Momentum
In Australia, the public health perspective played a crucial role in securing bipartisan support for the National Firearms Agreement (NFA). Prime Minister John Howard, a conservative leader, prioritised societal safety over individual firearm ownership rights, successfully championing comprehensive reforms despite resistance from gun lobby groups (Howard, 1996). Similarly, in New Zealand, Prime Minister Jacinda Ardern employed public health framing following the Christchurch shootings to unite political factions. By emphasising community safety and well-being, she gained strong public support for swift and far-reaching legislative changes (Ardern, 2019).
5.3 Sustained Impact
Policies grounded in a public health framework are widely regarded as systemic solutions that focus on prevention rather than punitive measures. This approach shifts the emphasis from reactive responses to proactive strategies aimed at reducing harm before it occurs. By addressing the root causes and societal impacts of issues like gun violence, public health narratives promote solutions that are both comprehensive and forward-looking. Their reliance on evidence-based data reinforces their credibility and ensures that reforms are tied to measurable outcomes, making them harder to dismiss or overturn. Furthermore, by aligning these policies with universally shared values such as safety, community well-being, and the protection of vulnerable populations, they garner broad public and political support. This combination of scientific rigour and moral resonance creates a durable foundation for reforms, safeguarding them against political reversals and ensuring their longevity (Chapman et al., 2006).
5.4 Bipartisan Potential
Public health arguments have the unique ability to bridge ideological divides, reducing polarisation and fostering consensus around the need for reform. By framing issues like gun violence in terms of economic and healthcare costs, these arguments resonate strongly with fiscal conservatives, who may be persuaded by the financial burden that gun-related injuries and deaths impose on healthcare systems and public resources. At the same time, the focus on safety, community well-being, and the protection of vulnerable populations appeals to progressive audiences, who prioritise social justice and preventative measures. This dual appeal makes public health narratives a powerful tool for uniting disparate political factions behind evidence-based reforms, creating a shared understanding of the broader societal benefits of preventative approaches (Hemenway, 2017).
6. Stakeholder Perspectives
Here insights from public health professionals, data-driven advocacy, human stories, and educational campaigns are discussed to illustrate how various stakeholders contribute to reframing gun violence as a preventable societal issue.
6.1 Insights from Public Health Professionals
Public health experts are instrumental in reshaping the discourse on gun violence, moving it away from a narrow focus on criminal justice and towards a broader framework centred on prevention. By leveraging evidence-based strategies, they illuminate the far-reaching societal costs of gun violence, including the physical, emotional, and economic burdens it imposes on individuals, families, and communities. Their emphasis on data and research underscores the preventable nature of firearm-related harm, reframing it as a public health crisis that demands systemic, proactive solutions rather than reactive, punitive responses. Through this approach, public health professionals help to redefine gun violence as an issue that affects society as a whole, fostering a more inclusive and effective dialogue on prevention.
6.2 Data-Driven Advocacy
Public health professionals rely on statistical evidence to construct persuasive arguments for preventative policies, drawing attention to metrics such as healthcare costs, emergency room visits, and the mental health impacts of gun violence (Kalesan et al., 2014). This data-driven approach highlights the tangible and measurable societal burdens of firearm-related harm, reinforcing the urgency of proactive interventions. In the United States, organisations like the Centers for Disease Control and Prevention (CDC) and the American Public Health Association (APHA) advocate for enhanced data collection on gun-related injuries to better inform policy decisions. However, these efforts often face significant political resistance, as funding and support for such initiatives are frequently hindered by ideological opposition and legislative constraints (Fleegler et al., 2013). Despite these challenges, public health experts continue to emphasise the critical role of comprehensive data in shaping effective and evidence-based policies.
6.3 Humanising the Crisis
Public health advocates go beyond statistics, bringing attention to the personal stories of survivors and the communities affected by gun violence. These narratives create powerful emotional connections that resonate with the public, fostering broader support for reform (Chapman, 2013). After the Port Arthur massacre, Australian health professionals collaborated with the media to shift the conversation, framing gun violence not as an unavoidable consequence of crime but as a preventable public health crisis. This reframing helped to galvanise public opinion and political will, illustrating the transformative power of combining evidence-based arguments with human stories to drive meaningful change (Howard, 1996).
6.4 Educational Campaigns
Public health initiatives focused on gun safety, such as campaigns promoting secure firearm storage and raising awareness about the risks of firearm-related suicide, have been highly effective in reducing accidental shootings and self-harm. In countries like Australia, these preventative measures have played a crucial role in lowering the incidence of gun-related injuries and deaths, demonstrating the impact of education and awareness in fostering safer practices and mitigating risks (Chapman et al., 2006).
6.5 Gun Control Advocates and Policymakers
Policymakers in Australia and New Zealand have recognised the critical role of public health framing in shifting public opinion and enabling meaningful reform. In Australia, Prime Minister John Howard utilised public health data to challenge opposition from gun lobby groups, effectively demonstrating that the societal costs of inaction—including loss of life and community trauma—far outweighed the preservation of individual firearm ownership rights (Howard, 1996). Similarly, in New Zealand, Prime Minister Jacinda Ardern’s government collaborated closely with public health experts to craft evidence-based reforms in the wake of the Christchurch shootings. By ensuring that these measures were effectively communicated to the public, the government secured widespread support for their implementation (Ardern, 2019).
In the United States, some progress has been achieved at the state level by integrating public health principles into legislation. For example, California has implemented gun violence restraining orders as part of efforts to prevent harm and reduce firearm-related risks. However, the national discourse remains dominated by the constitutional rights narrative, which continues to impede the adoption of comprehensive reforms. Public health advocates emphasise the importance of reframing the debate to focus on prevention, community safety, and the significant economic costs of gun violence, presenting these as universal concerns that transcend ideological divides (Hemenway, 2017).
Global advocacy efforts led by organisations such as the World Health Organisation (WHO) and the United Nations have been pivotal in promoting the recognition of gun violence as a public health epidemic. By framing firearm-related harm as a preventable crisis with significant societal and healthcare impacts, these international bodies have provided crucial support to reform movements in countries that adopt a public health approach. Their efforts highlight the global importance of evidence-based strategies to address gun violence and inspire nations to prioritise prevention and community well-being in their policymaking (WHO, 2018).
7. Conclusion
This review seeks to highlight the profound and long-lasting impact of adopting a public health framework to address gun violence, contrasting the successes in reducing civilian harm from firearms seen in Australia and New Zealand with the challenges of widespread homicide and mass shootings faced by the United States.
By reframing firearm-related harm as a preventable crisis rather than a matter solely of criminal justice, Australia and New Zealand opened the doors of public opinion to enact sweeping legislative reforms that significantly reduced gun-related deaths and injuries. These efforts demonstrate the power of public health narratives to unite diverse political factions, build public consensus, and foster enduring change.
In the United States, the persistent dominance of constitutional rights and criminal justice framings has stymied similar progress at the federal level. While some states, such as California, have incorporated public health principles into their approaches, these measures remain fragmented and insufficient to tackle the national scale of gun violence. The U.S. experience underscores the limitations of narrow legal and punitive approaches and highlights the need to expand the conversation to include the societal and healthcare impacts of firearm violence.
Globally, organisations like the World Health Organisation and the United Nations continue to advocate for public health approaches, recognising their ability to galvanise support for evidence-based, preventative policies. These international efforts, coupled with the experiences of Australia and New Zealand, offer a compelling blueprint for nations grappling with the complex challenge of gun violence.
Ultimately, this review affirms the importance of framing gun violence as a public health issue. By aligning reforms with universally shared values such as safety, well-being, and prevention, policymakers can create systemic solutions that address the root causes of firearm violence and ensure long-term resilience against political opposition. The public health perspective offers a path forward that prioritises saving lives, protecting communities, and reducing the societal burden of gun violence.
