This study examines the characteristics of parricide in Australia using 35 years of data from the National Homicide Monitoring Program. Findings illustrate the distinctiveness of parricide and the greater need to consider this form of lethal violence in responses to family violence.Key findingsParricide, or the homicide of a parent by their child, comprises 5% of homicides each year.Almost all parricides were of a single parent, although the homicide of both parents was more common in Australia than in other countries where estimates exist.Offenders were predominantly male but victimisation was more even.Parricide was largely gendered, with sons more likely to kill their fathers and daughters to kill their mothers.Offenders aged 10–17 years committed parricide at higher rates than older homicide offenders and almost a fifth of parricide offenders were delusional at the time of the homicide.

Over the last 15 years imprisonment rates have declined in Europe on average by 15 percent and in the United States by 30 percent. Does this imply that, after decades long prison growth, we are facing a period of penal moderation? Since crime has also decreased, any assessments of a “moderate turn” are premature without considering how much of this decline is just a consequence of declining crime. This article begins to answer these questions first by examining previous attempts to measure the impact of crime on prison populations. To obtain a more precise view of the causal mechanisms, and to overcome some of the controversies in earlier research, a distinction between volume effects and policy effects is introduced. Empirical analyses are reported using two samples. The long-term sample from the 1960s onwards exemplifies the diversity of penal responses and differing prison trends during the times of increased crime in nine Western countries. Comparisons with 35 European countries from 2008 to 2024 show that prison populations followed declining crime quite closely. The answer to the initial question remains negative: There are ever more prisoners relative to recorded crime and convictions, suggesting a lower custody threshold than before. The number of admissions has declined, but the average length of prison terms has grown in almost all European countries. Despite the nominal decline of prison populations there is no indication that European penal policy is shifting toward leniency.

This paper presents a novel argument proposing greater recognition of the stigmatic nature of the ‘psychopath’ label in the corporate crime context, particularly in relation to its use within academic research and in criminal judgments. Labelling theory and a communicative account of criminal law and punishment are applied to the issue. The stigmatic nature of the label, as well as its potential to over-stigmatise corporate offenders is assessed. Recommendations are forwarded, primarily in relation to the need for greater judicial engagement with the topic of psychopathy and corporate crime, and greater recognition of the stigmatic nature of the psychopathy label. Alternative labels are forwarded.

This study examines the spatial patterns of homicide in three 14th-century English cities—London, York, and Oxford—through the Medieval Murder Map project, which visualizes 355 homicide cases derived from coroners’ inquests. Integrating historical criminology with contemporary spatial crime theories, we outline a new historical criminology of space, focused on how urban environments shaped patterns of lethal violence in the past. Findings reveal similarities in all three cities. Homicides were highly concentrated in key nodes of urban life such as markets, squares, and thoroughfares. Temporal patterns indicate that most homicides occurred in the evening and on weekends, aligning with routine activity theory. Oxford had far higher homicide rates than London and York, and a higher proportion of organized group-violence, suggestive of high levels of social disorganization and impunity. Spatial analyses reveal distinct areas related to town-gown conflicts and violence fueled by student factionalism. In London, findings suggest distinct clusters of homicide which reflect differences in economic and social functions. In all three cities, some homicides were committed in spaces of high visibility and symbolic significance. The findings highlight how public space shaped urban violence historically. The study also raises broader questions about the long-term decline of homicide, suggesting that changes in urban governance and spatial organization may have played a crucial role in reducing lethal violence.

This project aimed to inform efforts to better detect and prevent child sexual abuse through a rigorous analysis of the prevalence and attitudinal, behavioural and demographic correlates of sexual feelings and/or offending against children amongst Australian men. The research measured the prevalence of offending and risk behaviours and attitudes amongst of a weighted sample of 1,945 Australian men over 18 years of age. Key findings of the project Around one in six (15.1%) Australian men reports sexual feelings towards children. Approximately one third of this group reports sexually offending against children. Around one in ten (9.4%) Australian men has sexually offended against children. Approximately half of this group (4.9%) reports sexual feelings towards children. In total, almost one in five (19.6%) Australian men in the study have sexual feelings for children and/or have sexually offended against children. The 4.9% of men with sexual feelings who have sexually offended against children differed from men with no sexual feelings or offending against children on a number of measures: Relationships Ź They were more likely to be married and reported higher levels of social support. Employment and wealth Ź They were almost three times more likely to be working with children. Ź They were more likely to earn a higher income. Health and wellbeing Ź They were more likely to report mild, moderate or severe anxiety and depression. Ź They were over four times more likely to report weekly binge drinking. Childhood abuse and neglect Ź They reported approximately twice the rate of adverse childhood experiences. Ź They were over six times more likely to report being sexually abused as children. Attitudes to child sexual abuse Ź They were more than 25 times more likely to hold attitudes conducive to online child sex offending. Online behaviour Ź They were more likely to use the internet more frequently and intensively. Ź They were much more active on social media. Ź They were significantly more likely to use encrypted apps and privacy services. Ź They were twice as likely to own cryptocurrency and over five times more likely to use cryptocurrency for online purchasing. Pornography consumption Ź They were over eleven times more likely to watch violent pornography and over twenty six times more likely to watch bestiality pornography. Ź They were over sixteen times more likely to purchase sexual content online. 29.6% of those with sexual feelings towards children want help; this is 4.5% of Australian men. These men were more likely to have sexually offended against children online and offline than men with sexual feelings who did not want help.

This study analysed posts from a darknet forum to examine approaches to desistance from offending among undetected child sexual offenders. Forum users discussed a range of approaches, but some were harmful to children, including the use of child sexual abuse material to avoid contact offending. Other less harmful desistance strategies were discussed, which included adjusting lifestyle, reducing internet use, and controlling access to children. Some users had a positive view of psychosocial services, while acknowledging the heightened risk of detection, and shared knowledge on how to remain undetected while seeking treatment. These findings highlight the need for psychosocial treatment avenues for child sexual offenders in the community that they perceive to have a low risk of leading to law enforcement detection.

The Violence Risk Scale (VRS) is a tool designed to assess and predict risk of future offending, inform decisions around therapeutic intervention and measure changes in violence risk as a result of treatment. This study investigated the discriminative and predictive validity of the VRS for Australian Aboriginal and non-Indigenous males convicted of violent offending in multiple jurisdictions.

The Violence Risk Scale (VRS) is a risk assessment tool designed to assess and predict risk of future offending, inform decisions around therapeutic intervention and measure changes in violence risk as a result of treatment. While the tool has been used extensively both internationally and in Australia, its applicability to our Australian population is unclear.

This study investigated the discriminative and predictive validity of the VRS for Australian Aboriginal and non-Indigenous males convicted of violent offending in multiple jurisdictions. The VRS total score had moderate discriminative accuracy for violent reoffending at five-year follow-up. However, Aboriginal males were significantly more likely to be categorized as high risk, and additional discrimination measures revealed variation in performance between Aboriginal and non-Indigenous males. Implications of the findings for correctional practice and recommendations to reduce bias in the assessment of Aboriginal offenders are discussed.

While much research has been undertaken on the public’s, professionals’ and perpetrators’ views about the causes of sexual offending, far less has been documented about victim/survivors’ understanding of this topic. However, victim/survivors may possess unique knowledge about the perpetration of sexual violence – including its causes – which has previously been overlooked. To address this gap, this exploratory research examined victim/survivor views via a mixed methods investigation (an online survey and semi-structured interviews with victim/survivors). It represents an advance over prior research as it differentiates victim/survivors’ views about the causes of sexual offending against children and adults. The study’s findings will be relevant to a wide range of policymakers and practitioners in the criminal justice arena. As government policies designed to prevent and respond to sexual violence are often implemented on behalf of victim/survivors, it is vital for criminal justice professionals to understand victim/survivors’ policy preferences as well as what informs these. This study makes a modest but important contribution toward this aim.

When the first edition of A Primer in Private Security was published, its principal purpose was to demonstrate that private policing was not a mere auxiliary to public law enforcement but a robust and rapidly growing institution with its own organizational forms, priorities, and traditions. At that time, the Hallcrest Report had just confirmed that private security personnel outnumbered public police officers in the United States, a landmark finding that set the tone for debates about the privatization of policing .

Nearly four decades later, the central argument remains as relevant as ever, but the field itself has changed dramatically. Private security is now not only a supplement to public policing but a global, technologically sophisticated industry involved in nearly every sector of modern life. While we think that the original book still remains relevant to security today, we suggest in this preface that the reader approach the content from the point of view of four major perspectives that dominate security  (the word “private” seems old fashioned and less appropriate given that what is public and what is private have become incredibly and interwoven largely as a result of media, especially social media). 

The four perspectives are:

1.     the domestic sphere of home and family,

2.     the economic sphere of business,

3.     the public sphere of local and state government, and

4.     the international sphere of global security and climate-related risk.

Police departments across the country have and continue to experience staffing challenges in full-time sworn officers. In an effort to address this issue, previous research has examined the motivations for becoming police officers, or why people want to become officers. An equally important question that may help with recruitment and staffing efforts among police agencies is ‘Why do people not want to become police officers?’ The current study fills this void using Qualtrics Panel data from 2,000 respondents across the United States. In doing so, this study (1) contributes to the existing body of research on reasons people choose a career in policing, (2) adds insight to the limited body of research that examines why people do not want a career in policing, and (3) provides nuance to this discussion by examining racial, ethnic, and gender variations in these outcomes. The practical and policy implications of these findings are explored within the context of previous and ongoing research to help address police staffing challenges.

The intent of this study was to determine whether two features of antisocial thought process, proactive and reactive criminal thinking, mediate the age-disciplinary infractions relationship in prison inmates. Participants were 2,487 male inmates admitted to a medium security federal prison sometime between 2003 and 2010. Analyzing both total and aggressive disciplinary infraction data, it was discovered that whereas the proactive (planned, calculated, amoral) features of criminal thought process mediated the age-infractions relationship, the reactive (impulsive, irresponsible, emotional) features did not. Results from this study suggest that one way advancing age may contribute to declining disciplinary infractions in prison is that older inmates are less likely than younger inmates to employ the planned, calculated, and amoral aspects of antisocial cognition. Whether this stems from age-related decrements in antisocial cognition awaits further study using changes in criminal thinking over time.

In the study of criminal decision-making, researchers commonly present participants with a hypothetical offending scenario and ask how likely participants would be to engage in a list of behavioral responses predetermined by the researchers. Recently, scholars have questioned the use of predetermined response sets and argued instead that participants should be allowed to self-report their own behavioral responses. Using a hypothetical assault scenario presented to separate samples of incarcerated persons and university students, the current study invited participants to evaluate a traditional, predetermined (PD) list of behavioral response options and also to report any additional subjectively-derived (SD) behaviors in which they might engage. The study then explored the added value of including the SD responses. Results indicate that in a few cases, the use of the additional SD response revealed novel behaviors not captured in the list of PD behaviors (mostly alternative forms of prosocial behaviors). Furthermore, when novel SD behaviors were reported, they generally were not the behaviors that participants indicated they would be most likely to actually engage in. Mindful of these findings, the value of SD responses in the study of criminal decision-making is discussed.

The disappearances of individuals are complex phenomena, spanning different regions and temporal periods. Evolving from different legal, social, and forensic disciplines, existing research has signaled the reasons for and contexts in which people disappear or go missing, as well as the development of investigative tools that assist, in fatal cases, in their identification. However, a different type of applied research, which we have labelled as data-based disappearance analysis (DDA), can offer statistical techniques to support the search for missing persons. In this paper, we review the literature on DDA, paying close attention to the evolution of this methodology and its contextual relevance. We highlight three applications by which DDA may support the search for missing persons: statistical inference, geospatial tools, and machine learning models and artificial intelligence. We demonstrate significant results using these applications, the potential misuses and ethical concerns, and draw lessons from their use. Lastly, we make recommendations to help researchers and practitioners support the search for missing persons.

From February 25 to 27, Peace in Our Cities (PiOC) members and experts, particularly from the African continent, met in Nairobi, Kenya, for the first Regional Workshop of the PiOC network, organized in partnership with the Life & Peace Institute (LPI). This regionally-focused workshop brought together PiOC member cities and representatives for knowledge exchange and experiential learning on topics such as gender-based violence, youth, data and technology, climate change, and organized criminal violence in the unique context of Africa’s rapid urbanization and social change. The three-day workshop included discussions, training sessions, and site visits to informal settlements of Nairobi, all to explore community-specific violence prevention strategies on the most pressing topics related to urban violence in the region. Cross-cutting insights across workshop elements included: – Violence as a complex phenomenon: Participants emphasized that violence is a multi-pronged and interconnected crisis, involving issues related to governance, gender, inequality, housing, climate change, unemployment, political participation, and more. – Prevention over suppression: Participants agreed that it is not enough to take action to stop violence as it happens, but that governments and other stakeholders need to identify and address the root causes of violence through holistic and whole-ofsociety approaches. – The need to build trust between the community and law enforcement: Participants expressed the importance of creating bridges between the community and the police. Although policing cannot be seen as the sole solution to violence prevention, it is crucial that community members can see law enforcement as reliable, safe, and responsive. – Young people as agents of change: Throughout the discussions, participants remarked that young people feel alienated from political conversations and decision-making, highlighting the need to elevate young people’s voices in discussions related to violence prevention. – Data as a tool for violence prevention: Participants highlighted the importance of using data to understand the violence that affects their communities and design more effective and bettertargeted violence prevention strategies, while expressing their concerns surrounding resource constraints. – Responding to challenges with better institutions and effective governance: Participants remarked on the need to build institutions and governance practices that can answer emerging global challenges such as organized crime, changes in the international funding landscape, and climate-related threats. – Networking and strategic partnerships: different sessions throughout the workshop brought to the fore the importance of coalition building between civil society actors and partnerships with key state actors to bridge the gap between policy and practice and ensure long-term sustainability of efforts to address urban violence. The workshop provided an opportunity for PiOC members to share their approaches and explore critical linkages for continued engagement

Outreach is an important approach to improve health and social care for women experiencing street involvement (SI) or gender-based violence (GBV). Few studies have examined outreach approaches that incorporate SI and GBV. Drawing on feminist theories and principles of community-based research, we detail an inclusive co-design approach for an outreach intervention considering these interrelated contexts. Women with lived experience, researchers, and service leaders drew on research and experiential knowledge to define outreach engagement principles: tackling GBV, personhood and relational engagement, trauma-informed engagement, and harm reduction engagement. The resulting intervention integrates these principles to enable building and sustaining relationships to facilitate care.

Novel opioids, including non-medical and non-opium-based opioids such as fentanyl analogues and nitazenes, pose a significant risk of harm due to their high potency. There is little published data on novel opioid detections and harms in Australia, yet they are implicated in multiple deaths. This study describes the detections and harms of novel opioids in New South Wales.

Methods

A retrospective analysis was conducted using four statewide datasets: Coronial Toxicology, the Illicit Drug Analysis Unit, the Prescription, Recreational and Illicit Substance Evaluation Program (PRISE), and the NSW Poisons Information Centre. These datasets were interrogated for available data (cases or substances seized by police) on novel opioid detections between 1 January 2019 and 31 May 2024.

Results

Overall, there were 106 novel opioid detections in 103 cases. PRISE identified 91% of clinical cases, reflecting the program's reach. Fentanyl analogues predominated until 2021, whereas nitazenes predominated from 2022. Most detections were acetylfentanyl (n = 54), followed by isotonitazene detections (n = 13). Positive detections were more frequent in urine compared to blood, supporting testing on both samples. Overall numbers were low, but they were often associated with harm, including deaths.

Discussion and Conclusions

We anticipate that these data underestimate the harms from novel opioids; for example, these drugs are not being tested routinely in laboratory testing of biological samples, and not all police seizures are analysed. A change in the predominant novel opioid was observed during the study period. Enhancing systems for readiness to detect and respond to novel opioids is vital, including resourcing laboratories.

Domestic, family and sexual violence (DFSV) is a pervasive and growing issue in Australia. Despite government-led national plans to reduce this violence in Australia, there is evidence that rates are increasing and incidences are becoming more severe. DFSV support agencies offer a range of services to support victim-survivors including targeted support to assist clients to leave violent relationships, access housing, legal and counselling support, as well as offering emotional and social support and support to recognise and define abusive and violent behaviour. 

This paper argues that these services also have the potential to lead to social change at a structural level as suggested by a reverse dominance coalition framework. 

Inequalities persist when they are normalised and celebrated by society. 'Reverse dominance coalitions' make cultural change possible by establishing large collectives of people who speak out in solidarity, develop alliances and collectively establish expectations of equality.

Data from interviews of victim-survivors is used to illustrate the applicability of the reverse dominance coalition framework to DFSV support services. 

The paper finds that the framework offers a means of understanding how support at an individual level to victim-survivors also has broader transformative power to change societal awareness, attitudes and responses. It concludes that DFSV agencies not only assist DFSV victims to recover and heal but also play a leadership role in promoting broader changes at the community, policy and societal level.

This Australian study examined the frequency and clinical signs of neck injury among domestic and family violence (DFV) patients reporting strangulation in Victorian police regions and the forensic service response during a physical and/or sexual assault. The study compared the characteristics between patients with/without clinical signs of neck injury and between physical and sexual assault where a forensic practitioner performed a medical examination. Of 522 eligible patients of physical and/or sexual assault, 84 (16 %) self-reported strangulation. Amongst the 84 patients, 63 had complete forensic examination data. Of the 63 examinations, 38 were for physical assaults and 25 for sexual assaults. Observable neck injury was reported in 75 %. About half of the patients undergoing forensic examinations displayed neck injuries specific to non-fatal strangulation. Danger-to-life assessment, substance abuse, comorbidities, and previous domestic violence were comprehensively reported. This study suggests that observable neck injuries are associated with self-reported strangulation. The findings will inform policy, and response services, about the features of nonfatal strangulation in DFV in Victoria.

Report 24 of the National Wastewater Drug Monitoring Program is based on data collected in August (capital city and regional sites) and October 2024 (capital city sites only). Sixty-one wastewater treatment plants participated nationwide, covering approximately 57% of the population. This provides a comprehensive picture of Australia’s illicit drug markets and drug consumption habits for 12 substances. Report 24 also provides data for the 8th year of the program, allowing for comparisons with previous years.

Findings

The Australian Criminal Intelligence Commission has commissioned The University of Queensland, and through it the University of South Australia, to undertake the data collection and analysis that underpins the report.This latest report reveals that 22.2 tonnes of methylamphetamine, cocaine, heroin and MDMA was consumed between August 2023 and August 2024. This is a 34% increase from the previous year, driven by record high consumption of all 4 drugs. 

Longitudinal figures

Longitudinal figures are available for each state and territory and broken down by drug type. These figures offer a guide to trends over the period the respective drugs have been monitored by the wastewater program.
