We analysed the chat logs of seven Australia-based men who had committed 145 child sexual abuse (CSA) live streaming offences, to examine the overlap between this offending, contact sexual offending and engagement with child sexual abuse material (CSAM).

Four CSA live streaming offenders attempted to travel to offend against victims in person, in that they discussed travelling or actually booked flights in order to meet these children. Offenders also requested or received images and videos of victims they had viewed over live stream, and recorded live streams to produce CSAM.

Travelling to offend against children, use of CSAM and CSA live streaming appear to be interrelated and should be considered by law enforcement as potential risk factors for one another. Further, detection and removal of new CSAM, and scanning of live streams for abusive content, should be a priority for all electronic service providers.

Online CSAM offending is a challenge for law enforcement, policymakers and child welfare organisations alike. The use of online warning messages to prevent or deter an individual when they actively search for CSAM is gaining traction as a response to some types of CSAM offending. Yet, to date, the technical question of how warning messages can be implemented, and who can implement them, has been largely unexplored. To address this, we use a case study to analyse the actions individuals and organisations within the technology, government, non-government and private sectors could take to implement warning messages. We find that, from a technical perspective, there is considerable opportunity to implement warning messages, although further research into efficacy and cost is needed.

This study analyses data from a survey of Australian adult computer users conducted in June 2021 to examine the influence of online routine activities and life stressors on the likelihood of profit-motivated cybercrime victimisation.

Compared with non-victims, victims spent more time online, more frequently engaged in recreational online activities and were more likely to employ higher-risk online practices. Small-to-medium enterprise owners working from home were more likely to be victims. Respondents who had experienced recent increases in financial stress and gambling and negative impacts on interpersonal relationships during the COVID-19 pandemic were also more likely to be a victim of cybercrime.

Being accessible online and a lack of personal and physical guardianship are associated with an increased risk of being a victim, but other factors may influence the susceptibility of computer users to cybercrime victimisation. This has important implications for cybercrime responses

AIM To examine whether longer apprehended domestic violence orders (ADVO) are associated with changes in domestic violence (DV) offending and ADVO breaches. METHOD A dataset of 13,717 defendants who were placed on an ADVO after a DV incident between January 2016 and April 2018 was extracted from the NSW Bureau of Crime and Statistics and Research’s ADVO database. This included 10,820 defendants subject to a final 12-month order, and 2,897 defendants subject to a final 24-month order. We utilised an entropy balancing matching approach to ensure groups of defendants subjected to differing ADVO lengths were comparable and implemented an event study analysis to examine quarterly differences in offending outcomes in the three years after the start of the order. In doing so, we were able to examine relative differences in offending in the first 12 months (where both groups were subject to an ADVO), the second 12 months (where only the 24-month ADVO group were subject to an ADVO), and the third 12 months (where neither group were subject to an ADVO). RESULTS In the 12 to 24 month period, where ADVOs with a longer duration were active and shorter ADVOs were not, longer ADVOs were associated with increased breach offending and decreased DV offending. Specifically, in the 5th, 6th and 7th quarters after the beginning of a final order we observed 3.4 percentage points (p.p.), 4.1 p.p., and 2.3 p.p. increases in defendants breaching their ADVO, respectively. When considering baseline rates of breaching, this represents relative increases of 79% to 161%. In the 5th, 6th, and 7th quarters after the beginning of a finalised order, longer ADVOs were associated with respective 1.8 p.p., 2.0 p.p., and 3.1 p.p. decreases in DV offending, reflecting relative decreases in DV offending by 41% to 59%. We find no group differences in DV offending or breaches in the subsequent 12 months, when ADVOs for both groups had expired. While the study examined multiple factors related to both longer ADVO length and offending, we cannot exclude the possibility that unobserved factors may be influencing our results. CONCLUSION Relative to 12-month ADVOs, 24-month ADVOs were associated with an increase in the probability that an offender breaches the conditions of their ADVO, and a decrease in the probability that an offender commits a proven DV offence.

AIM To quantify the effects of individual liquor licensing policies introduced in New South Wales (NSW) over the last decade on rates of violent crime. METHOD: The effects of individual state-wide policies on non-domestic assaults in NSW and additional local policies in the Sydney Central Business District Entertainment Precinct (CBD) and the Kings Cross Entertainment Precinct (KCP) from 2000 to 2019 were quantified using time series intervention models. We used a vector auto regression (VAR) model to create counterfactual datasets. These datasets were derived from proxy data outside the study area and helped predict potential assault outcomes without the policy implementation. RESULTS: The liquor licensing policies introduced by the NSW Government between 2008 and 2018 contributed to a significant decline in non-domestic assaults, both in Sydney and across NSW. By the end of 2019, non-domestic assaults had reduced by an estimated 19% in NSW, 45% in the Sydney CBD, and 84% in the KCP. Policies restricting late night (or 24-hour) trading of licensed premises and those targeting enforcement toward the highest risk venues contributed most to these declines. CONCLUSION: This research adds to the mounting evidence that restricting trading hours can substantially reduce the risks associated with acute alcohol intoxication and can be a cost-effective crime reduction strategy when combined with enforcement that targets the small number of premises that account for most of the harm.

This study investigated the risk factors for dating app and website users receiving requests from other users to facilitate child sexual exploitation and abuse (CSEA). It did so by analysing data from a large survey (n=9,987) of dating app and website users residing in Australia.

Dating app and website users who were younger, lived with children, were Indigenous or had a health condition (ie disability) were more likely than other users to be asked to facilitate CSEA. Further, respondents who were more frequent or active dating app/website users, who paid for the dating service or who linked their social media account to their dating profile were also more likely to receive requests for CSEA. These findings can assist online dating companies to implement new features and education messages that protect users and their children from harm.

Importance  Youths, especially Black and Hispanic males, are disproportionately affected by firearm violence. Yet, no epidemiologic studies have examined the incidence rates of nonfatal firearm injury and firearm mortality in those who may be at greatest risk—youths who have been involved with the juvenile justice system.

Objectives  To examine nonfatal firearm injury and firearm mortality in youths involved with the juvenile justice system and to compare incidence rates of firearm mortality with the general population.

Design, Setting, and Participants  The Northwestern Juvenile Project is a 25-year prospective longitudinal cohort study of 1829 youths after juvenile detention in Chicago, Illinois. Youths were randomly sampled by strata (sex, race and ethnicity, age, and legal status [juvenile or adult court]) at intake from the Cook County Juvenile Temporary Detention Center. Participants were interviewed at baseline (November 1995 to June 1998) and reinterviewed as many as 13 times over 16 years, through February 2015. Official records on mortality were collected through December 2020. Data analysis was conducted from November 2018 to August 2022.

Main Outcomes and Measures  Participants self-reported nonfatal firearm injuries. Firearm deaths were identified from county and state records and collateral reports. Data on firearm deaths in the general population were obtained from the Illinois Department of Public Health. Population counts were obtained from the US census.

Results  The baseline sample of 1829 participants included 1172 (64.1%) males and 657 (35.9%) females; 1005 (54.9%) Black, 524 (28.6%) Hispanic, 296 (16.2%) non-Hispanic White, and 4 (0.2%) from other racial and ethnic groups (mean [SD] age, 14.9 [1.4] years). Sixteen years after detention, more than one-quarter of Black (156 of 575 [27.1%]) and Hispanic (103 of 387 [26.6%]) males had been injured or killed by firearms. Males had 13.6 (95% CI, 8.6-21.6) times the rate of firearm injury or mortality than females. Twenty-five years after the study began, 88 participants (4.8%) had been killed by a firearm. Compared with the Cook County general population, most demographic groups in the sample had significantly higher rates of firearm mortality (eg, rate ratio for males, 2.8; 95% CI, 2.0-3.9; for females: 6.5; 95% CI, 3.0-14.1; for Black males, 2.5; 95% CI, 1.7-3.7; for Hispanic males, 9.6; 95% CI, 6.2-15.0; for non-Hispanic White males, 23.0; 95% CI, 11.7-45.5).

Conclusions and Relevance  This is the first study to examine the incidence of nonfatal firearm injury and firearm mortality in youths who have been involved with the juvenile justice system. Reducing firearm injury and mortality in high-risk youths and young adults requires a multidisciplinary approach involving legal professionals, health care professionals, educators, street outreach workers, and public health researchers.

Every year, individuals with ties to different extreme causes and movements kill people in the United States; the ADL Center on Extremism (COE) tracks these murders. Extremists regularly commit murders in the service of their ideology, to further a group or gang they may belong to, or even while engaging in traditional, non-ideological criminal activities.

In 2023, domestic extremists killed at least 17 people in the U.S., in seven separate incidents. This represents a sharp decrease from the 27 extremist-related murders ADL has documented for 2022—which itself was a decrease from the 35 identified in 2021. It continues a trend of fewer extremist-related killings after a five-year span of 47-79 extremist-related murders per year (2015-2019). One reason for the trend is the decrease in recent years of extremist-related killings by domestic Islamist extremists and left-wing extremists.

The 2023 murder totals include two extremist-related shootings sprees, both by white supremacists, which together accounted for 11 of the 17 deaths. A third shooting spree, also by an apparent white supremacist, wounded several people but luckily did not result in fatalities.

All the extremist-related murders in 2023 were committed by right-wing extremists of various kinds, with 15 of the 17 killings involving perpetrators or accomplices with white supremacist connections. This is the second year in a row that right-wing extremists have been connected to all identified extremist-related killings.

Two of the incidents from 2023 involved women playing some role in the killing or its aftermath. This report includes a special section that examines the role played by women in deadly extremist violence in the United States by analyzing 50 incidents from the past 20 years in which women were involved in some fashion in extremist-related killings

Human trafficking is a serious crime that continues to plague the United States. With the rise of computing technologies, the internet has become one of the main mediums through which this crime is facilitated. Fortunately, these online activities leave traces which are invaluable to law enforcement agencies trying to stop human trafficking. However, identifying and intervening with these cases is still a challenging task. The sheer volume of online activity makes it difficult for law enforcement to efficiently identify any potential leads. To compound this issue, traffickers are constantly changing their techniques online to evade detection. Thus, there is a need for tools to efficiently sift through all this online data and narrow down the number of potential leads that a law enforcement agency can deal with. While some tools and prior research do exist for this purpose, none of these tools adequately address law enforcement user needs for information visualizations and spatiotemporal analysis. Thus to address these gaps, this thesis contributes an empirical study of technology and human trafficking. Through in-depth qualitative interviews, systemic literature analysis, and a user-centered design study, this research outlines the challenges and design considerations for developing sociotechnical tools for anti-trafficking efforts. This work further contributes to the greater understanding of the prosecution efforts within the anti-trafficking domain and concludes with the development of a visual analytics prototype that incorporates these design considerations.

Congress requires courts to consider several factors when determining the appropriate sentence to be imposed in federal cases, among them the “history and characteristics of the defendant.” The sentencing guidelines also specifically authorize judges to consider an offender’s age when determining whether to depart from the federal sentencing guidelines. In this report, the Commission presents information on a relatively small number of offenders who were aged 50 or older at the time they were sentenced in the federal system. In particular, the report examines older federal offenders who were sentenced in fiscal year 2021 and the crimes they committed, then assesses whether age was given a special consideration at sentencing. This report specifically focuses on three issues that could impact the sentencing of older offenders: age and infirmity, life expectancy, and the risk of recidivism.

For the first time, this report provides in-depth criminal history information about federal economic crime offenders, combining the most recently available data from two United States Sentencing Commission projects. Key findings are that the application of guideline criminal history provisions differed among the different types of economic crime offenders. Also, The extent of prior convictions differed among the different types of economic crime offenders. Federal economic crime offenders did not “specialize” in economic crime. The severity of criminal history differed for offenders in the specific types of economic crime. Only about one-quarter of federal economic crime offenders with prior convictions were not assigned criminal history points under the guidelines.

This study expands on prior Commission research by examining the geographic mobility of federal offenders. For this report, mobility is defined as having convictions in multiple states, including the location of the conviction for the instant offense. This report adds to the existing literature on offender criminal history in two important ways. First, the report provides information on how mobile federal offenders are, as measured by the number of offenders with convictions in multiple states. Second, the report provides information on the proportion of offenders with convictions in states other than the state in which the offender was convicted for the instant offense. The report also examines the degree to which out-of-state convictions in offenders’ criminal histories contributed to their criminal history score and their Criminal History Category.

Introduction: The Dark Web is a subsection of the Internet only accessible through specific search engines, making it impossible to trace users. Due to extensive anonymity, the drug trade on the Dark Web makes regulation complicated. We sought to uncover the scope of the online drug trade on the Dark Web and the impact it may have on the dynamics of global drug trafficking.

Methods: We conducted a literature review to elucidate the availability and distribution of drugs on the Dark Web based on data reported in existing literature (n = 14) between September 2012 and June 2019. We simultaneously collected data about substances and listings from Dark Web cryptomarkets (n = 13) active between August 2022 and January 2023. Data from the literature review and the Dark Web scrape were combined to draw trends in the chronological availability and distribution of drugs between 2012 and 2023.

Results: The data collected from 13 cryptomarkets between late 2022 and early 2023 showed a relative change in substance distribution compared to 2012–2019, with a decrease in prescription drugs (from >20% to <5%) and a doubling of opioid listings (from 5.5% to 9.25%), while no major changes were observed on average during 2012–2019 according to literature.

Conclusions: The Dark Web warrants more attention in the analysis of the global drug trade. Understanding Dark Web drug markets can inform targeted interventions and strategies to reduce drug-related harms, while ongoing research is necessary to anticipate and respond to future changes in the landscape of the illicit drug trade.

Although economic sociology emphasizes the role of social networks for shaping economic action, little research has examined how network governance structures affect prices in the unregulated and high-risk social context of online criminal trade. We consider how over-embeddedness—a state of excessive interconnectedness among market actors—arises from endogenous trade relations to shape prices in illegal online markets with aggregate consequences for short-term gross illegal revenue. Drawing on transaction-level data on 16 847 illegal drug transactions over 14months of trade in a ‘darknet’ drug market, we assess how repeated exchanges and closure in buyer– vendor trade networks nonlinearly influence prices and short-term gross revenue from illegal drug trade. Using a series of panel models, we find that increases in closure and repeated exchange raise prices until a threshold is reached upon which prices and gross monthly revenue begin to decline as networks become over-embedded. Findings provide insight into the network determinants of prices and gross monthly revenue in illegal online drug trade and illustrate how network structure shapes prices in criminal markets, even in anonymous trade environments.

What are the economics of the cyber drug trade that is rampant across the globe? What are the impacts that an illicit online drug trade can have on the economy? How does the economy take into consideration the unreported transactions on the dark side of the internet and what are the positive and negative implications of a widespread trade like this in these globalizing times? This research paper aims to analyze various data and information to find and conclude how the darknet drug trade has had significant economic impact on the international financial sector. This paper also elaborates on why the black market is highly prevalent in the current times and what are the ill-effects of Darknet, in particular, drug trade on the Darknet. The analysis of economic consequences of unreported dealings is also taken into consideration and elaborated on. The paper sheds light on the bleak and disturbing statistics of involvement of various countries in the online drug ring marketplace with countries like the United States, India and Turkey dealing heavily in the illegal Darknet drug markets. A statistical analysis to determine the economic calculations of the drug trade is depicted and conclusions about the economical structure of the dark net drug trade and markets and its impact through the times is elaborated upon. The ill-effects of the Darknet drug trade are highlighted and conclusions drawn in the paper depict the fluctuating condition of the online illegal drug trade market.
