The National Strategy to Combat Human Trafficking (National Strategy) is a five-year (2019-2024) strategy aiming to strengthen Canada’s response to human trafficking. It follows from the National Action Plan to Combat Human Trafficking which expired in 2016. The National Strategy is a whole of government endeavour that aligns efforts with the internationally recognized pillars of prevention, protection, prosecution and partnership. Canada has added a fifth pillar, empowerment, to enhance support and services to victims and survivors of human trafficking. The activities under the pillars are the responsibility of many partner departments and agencies. Several partner departments and agencies received funding for activities specific to the National Strategy. These include, Public Safety Canada (PS), the Canada Border Services Agency (CBSA), the Financial Transactions and Reports Analysis Centre (FINTRAC), Women and Gender Equality (WAGE) Canada, Immigration, Refugees and Citizenship Canada (IRCC), and Public Services and Procurement Canada (PSPC). Other departments and agencies supported efforts under the National Strategy with pre-established funding. These partners are the Royal Canadian Mounted Police (RCMP), Global Affairs Canada (GAC), Justice Canada (JUS), and Employment and Social Development Canada (ESDC). Additionally, Statistics Canada (StatsCan) receives funding from PS for activities that support the National Strategy, including data collection and research projects.

The purpose of the evaluation was to assess the relevance, effectiveness and efficiency of the National Strategy. The evaluation covered the period from fiscal year 2019-2020 to 2022-2023 and was conducted in accordance with the Treasury Board Policy on Results and the Directive on Results.

This report estimates the cost of pure cybercrime to individuals in Australia in 2019. A survey was administered to a sample of 11,840 adults drawn from two online panels—one using probability sampling and the other non-probability sampling—with the resulting data weighted to better reflect the distribution of the wider Australian population.

Thirty-four percent of respondents had experienced some form of pure cybercrime, with 14 percent being victimised in the last 12 months. This is equivalent to nearly 6.7 million Australian adults having ever been the victim of pure cybercrime, and 2.8 million Australians being victimised in the past year.

Drawing on these population estimates, the total economic impact of pure cybercrime in 2019 was approximately $3.5b. This encompasses $1.9b in money directly lost by victims, $597m spent dealing with the consequences of victimisation, and $1.4b spent on prevention costs. Victims recovered $389m.

This study presents the results from a survey of 14,994 Australian adult computer users conducted in June 2021.

Nearly five percent of all respondents had ever experienced ransomware victimisation, while two percent of respondents had experienced ransomware in the last 12 months.

Small to medium enterprise (SME) owners were twice as likely as other respondents to have been the victim of ransomware attacks in the past year and were more likely to have paid the ransom. The prevalence of ransomware victimisation varied according to the industry in which respondents were currently employed.

Most ransomware victims did not pay the ransom. The advice given to ransomware victims was identified as the most common reason for a respondent’s decision about whether or not to pay the ransom, particularly in the case of SME owne

Research question - 

Sexual Risk Orders (SRO) have been advocated as a means to prevent Violence Against Women and Girls (VAWG). This is despite significant detriment to the fundamental rights of the legally innocent and a lack of empirical assessment that can speak to preventative efficacy. This study asks; do SROs serve to prevent sexual-harm?

Data - 

The Police National Computer (PNC) was used to identify two samples of SRO subjects. Legal Services’ data from the Metropolitan Police Service (MPS) was used to construct a counterfactual group, for whom SRO was considered but not obtained. PNC was used to identify arrests as a proxy for offending and a harm index applied.

Methods - 

Before-after and between-group comparisons are used, along with an interrupted-time-series analysis, to assess the relationship between SRO and sexual-harm prevention. Rank-ordering of harm caused by alleged sexual-offenders in London enables an estimate of how precisely SROs are used against the highest-harm offenders.

Findings - 

SROs are associated with a significant 84.5% reduction in sexual-harm. This increases to a 93.1% reduction in the case of high-harm offenders, controlling for time incarcerated. Despite this, SROs are rarely used and are not systematically targeted against the most harmful offenders.

Conclusions - 

Within the limitations of the methodology we conclude that the evidence supports SRO use as a primary tactic to counter VAWG. Preventative impact may be maximised by increasing use, actively targeting SROs at the highest-harm offenders and considering use at an earlier stage of a subjects sexual-offending. A randomised trial is the next logical step to augment causal inference.

Fenethylline (street name, captagon) is a synthetic amphetamine-type stimulant that is emerging as a significant public health and security concern, particularly in the Middle East. This systematic review synthesizes original research articles, epidemiological studies, systematic reviews, policy analyses, and case reports to provide a comprehensive analysis of fenethylline’s health impacts, addiction potential, and dynamics of illicit trade. Initially developed for therapeutic use, fenethylline illicit production and use have escalated, raising concern about its physiological, psychological, and socio-economic impacts. This stimulant profoundly affects the central nervous system, enhancing wakefulness, concentration, and physical stamina while inducing euphoria. These effects come at the cost of serious adverse health outcomes, particularly with prolonged or heavy use, including cardiovascular complications, neurological damage, and addiction. The dependence-forming nature of captagon contributes to escalating substance use disorders, placing a burden on healthcare systems. Beyond its biomedical implications, fenethylline trafficking has become a global issue, with supply chains deeply intertwined with politically unstable regions where illicit economies thrive. The geopolitical dimensions of captagon’s trade amplify its global security threat, influencing international relations and regional stability. This paper underscores the urgent need for systematic data collection and coordinated efforts to regulate illicit fenethylline production and distribution. Strategies such as improved surveillance, public health interventions, and international cooperation are essential to mitigate its escalating risks. Addressing this issue requires a multidisciplinary approach, integrating public health, law enforcement, and policy development to curb its impact on global health and security.

Objectives

There is empirical evidence that sexual recidivism rates have been dropping for several decades, but it remains unclear whether this drop is an artifact of changing research methodologies over the years. The current study, therefore, examines whether the sexual recidivism drop is robust while accounting for various methodological factors.

Method

The study is based on a systematic review and a quantitative meta-analysis of 468 empirical studies published between 1940 and 2019 that reported sexual recidivism rates. A total of 626 estimations (n = 388,994) of sexual recidivism were retrieved for the study period and of those, 238 were independent observations (n = 196,651). A series of sensitivity analyses were conducted using a meta-regression approach.

Results

A series of meta-regression analyses show that, even after accounting for various methodological factors (e.g., study settings, follow-up length, recidivism criteria), there has been a sexual recidivism rate drop of about 45–60% since the 1970s.

Conclusions

The study findings confirm the presence of a sexual recidivism drop while recognizing that sexual recidivism rates are sensitive to methodological details.

This report summarizes law enforcement reports of sexual assault offenses for the State of Ohio during the years 2016-2023. We also summarize characteristics of crime incidents, victims and suspects. We provide sexual assault rates throughout this report, and it is important to understand how we calculated them and what they mean. First, we calculate offense totals by counting the number of sexual assault victimizations documented within each law enforcement incident report. Sexual assault victim totals do not necessarily represent unique victims. For example, law enforcement could report that a suspect sexually assaulted an individual more than once during a single incident. Further, a suspect could assault the same individual during a different incident. Therefore, it is almost certain that the sexual assault offense total is larger than the number of individuals who were victims of sexual assaults. Next, we calculate the rate of sexual assault by dividing the sexual assault total by the population total and then multiplying the resulting number (the quotient) by 100,000. This yields a sexual assault crime rate per 100,000 persons. We provide Ohio’s overall sexual assault crime rates over time, and we also compare rates of sexual assault for Ohio’s standard demographic groups (e.g., age, sex, race). Rates can vary significantly depending on how many victimizations a group experienced as well as the size of one group versus another. For example, the sexual assault crime rate is much higher for female Ohioans than males, largely because the number of female sexual assaults is much larger than male. Further, most sexual assault victims are White females because most of Ohio is White. However, Black females have the highest victimization rate because their sexual assault total is large while their overall population size is small.

In this publication, the term “femicide” is used to refer to all types of gender-related killings of women and girls as described in the “Statistical framework for measuring the gender-related killing of women and girls (also referred to as “femicide/feminicide”)”.

Globally, approximately 51,100 women and girls were killed by their intimate partners or other family members during 2023. Higher than the 2022 estimate of 48,800 victims, this change is not indicative of an actual increase as it is largely due to differences in data availability at the country level. The 2023 figure means that 60 per cent of the almost 85,000 women and girls killed intentionally during the year were murdered by their intimate partners or other family members. In other words, an average of 140 women and girls worldwide lost their lives every day at the hands of their partner or a close relative...

P.18 When considering possible risk factors, it should be noted that fewer victims (11 per cent) and perpetrators (20 per cent) of femicides are under the influence of alcohol than in the case of male homicides (25 and 30 per cent respectively). Some studies point to the drug intoxication of victims as a homicidal risk factor,13 but in the case of femicides in France, this does not seem to be the case, with 3 per cent of victims and 5 per cent of perpetrators of femicide being under the influence of drugs at the time of the crime.

The Labour government has committed to halving knife crime in a decade.

This briefing provides an overview of legislation concerning knives and offensive weapons, and the approaches taken by the police and other agencies to prevent serious violence in England and Wales.

What are knife crime offences? It is a criminal offence to possess any knife or other bladed article in a public place, under section 139 of the Criminal Justice Act 1988. It is also a criminal offence to have an “offensive weapon” in any public place, under section 1 of the Prevention of Crime Act 1953. Both offences carry maximum penalties of up to four years’ imprisonment. It is a defence for someone to prove they have possessed a knife, bladed article or offensive weapon with “good reason or lawful authority”, though the legislation does not provide examples of what this means in practice. A court determines whether the explanation provided by a defendant amounts to lawful authority or reasonable excuse based on the specific circumstances of a case. It is also a criminal offence to possess any prohibited weapon under section 141 of the Criminal Justice Act 1988 (as amended by the Offensive Weapons Act 2019). Prohibited weapons cannot be possessed anywhere, even in private, and are also illegal to hire, lend or manufacture. Like other possession offences, the maximum penalty is four years’ imprisonment. There are currently 20 prohibited weapons listed in secondary legislation under the Criminal Justice Act 1988 (Offensive Weapons) Order 1988, including a range of knives, bladed articles and other weapons. Under section 141(2) of the 1988 act, the government can introduce secondary legislation to add further weapons to this list. In 2024, the government added a new definition of “zombie-style” knives and machetes to the list, and launched a consultation on adding “ninja swords” to the list. Sentencing statistics from the Ministry of Justice shows that in the year ending March 2023, there were almost 18,500 cautions and convictions made for possession of a knife or offensive weapon. Juveniles (aged 10-17) were the offenders in around 17.3% of cases. Further data for England and Wales related to knife-related offences can be found in the Library briefing: Knife Crime Statistics: England and Wales.

Key Takeaways This study updates and supplements previous U.S. crime trends reports by the Council on Criminal Justice (CCJ) with data through December 2024. It examines yearly and monthly rates of reported crime for 13 violent, property, and drug offenses in 40 American cities that have consistently reported monthly data over the past six years. The 40 cities are not necessarily representative of all jurisdictions in the United States. Not all cities published data for each offense (see the Appendix for which cities reported which offenses); trends in offenses with fewer reporting cities should be viewed with caution. Not all crimes are reported to law enforcement. In addition, the data collected for this report are subject to revision by local jurisdictions. Reported levels of 12 of the 13 offenses covered in this report were lower in 2024 than in 2023; shoplifting was the only offense higher in 2024 compared to 2023. Looking at changes in violent offenses from 2023 to 2024, the number of homicides in the 29 study cities providing data for that crime was 16% lower, representing 631 fewer homicides. There were 4% fewer reported aggravated assaults, 15% fewer gun assaults, 6% fewer sexual assaults, and 4% fewer domestic violence incidents last year than in 2023. Robbery fell by 10% while carjackings (a type of robbery) decreased by 32%. Motor vehicle theft had been on the rise from the summer of 2020 through 2023, but that trend reversed last year; there were 24% fewer motor vehicle thefts in 2024 than in 2023. Reports of residential burglaries (-13%), nonresidential burglaries (-6%), larcenies (-5%), and drug offenses (-3%) all decreased in 2024 compared to 2023. But rates of reported shoplifting, a crime that has received extensive attention from the media and policymakers, increased by 14% over the same period. Examining trends over a longer timeframe, most violent crimes are at or below levels seen in 2019, the year prior to the onset of the COVID pandemic and racial justice protests of 2020. There were 6% fewer homicides in the study cities in 2024 than in 2019. Similarly, sexual assault (-26%), domestic violence (-11%), and robbery (-19%) were lower in 2024 than in 2019. In contrast, aggravated assaults (+4%), gun assaults (+5%), and carjackings (+25%) were higher in 2024 than in 2019. Homicide rates in some high-homicide cities, including Baltimore, Detroit, and St. Louis, have dropped even further, returning to the levels of 2014, when national homicide rates were at historic lows. Rates in other cities have largely returned to pre-pandemic levels. Property crime trends have been mixed over the last five years. There were fewer residential burglaries (-38%) and larcenies (-12%) in 2024 than in 2019, but more nonresidential burglaries (+12%) and shoplifting (+1%). Motor vehicle thefts were higher by half (+53%) during the timeframe. Drug offenses in 2024 were 28% below 2019 levels. While these crime reductions are promising, the United States still experiences high levels of homicide compared to other industrialized nations, and progress should not slow local, state, federal, and community efforts to adopt comprehensive, evidencebased strategies to reduce violence. Furthermore, researchers should redouble their efforts to identify how broad behavioral shifts and other societal dynamics may affect trends.

Objectives: This study investigates the effect of advertised rewards in credential leaks on the likelihood and speed of account hijacking. Methods: In an online field experiment, we created 176 honey Gmail accounts and randomly assigned them to eight different posts containing account credential leaks. We used a 2 × 2 experimental design, manipulating two key variables within the post titles: the number of accounts (5 K or 1.5 M) and the promise of access to additional platforms (absent or present). We then monitored the accounts for any subsequent activity. Results: Our findings indicate that the promise of access to additional platforms increased the likelihood and speed of an attempted access. Only 12 accounts were fully accessed, however, because most hijackers did not complete the second-factor authentication (2FA) process required for gaining full access. It seems that the 2FA acted as a deterrent to complete Gmail account hijacking. Conclusions: The study aligns with the rational choice perspective of crime, showing that the prospect of greater rewards leads to more attempted account accesses

Criminal expertise plays a crucial role in the choices offenders make when committing a crime, including their modus operandi. However, our knowledge about criminal decision making online remains limited. Drawing on insights from cyber security, we conceptualize the cybercrime commission process as the sequence of phases of the cyber kill chain that offenders go through. We assume that offenders who follow the sequence consecutively use the most efficient hacking method. Building upon the expertise paradigm, we hypothesize that participants with greater hacking experience and IT skills undertake more efficient hacks. To test this hypothesis, we analyzed data from 69 computer security and software engineering students who were invited to hack a vulnerable website in a computer lab equipped with monitoring software, which allowed to collect objective behavioral measures. Additionally, we collected individual measures regarding hacking expertise through an online questionnaire. After quantitatively measuring efficiency using sequence analysis, a regression model showed that the expertise paradigm may also apply to hackers. We discuss the implications of our novel research for the study of offender decision-making processes more broadly.

Objectives: Crime pattern theory and the related empirical research have remained rather a-temporal, as if the timing of routine activities and crime plays no role. Building on previous geography of crime research, we extend crime pattern theory and propose that an offender’s spatial knowledge acquired during daily routine activities is not equally applicable to all times of day. Methods: We put this extended theory to a first empirical test by applying a discrete spatial choice model to detailed information from the Netherlands on 71 offences committed by 30 offenders collected through a unique online survey instrument. The offenders reported on their most important activity nodes and offence locations over the past year, as well as the specific times they regularly visited these locations. Results: The results show that almost 40% of the offences are committed within the neighbourhoods of offenders’ activity nodes, increasing to 85% when including first-, second- and third-order neighbourhoods. Though not statistically significant in our small sample, the results further suggest that offenders are more likely to commit crime in neighbourhoods they have regularly visited at the same time of day than in neighbourhoods they have regularly visited at different times of day. Conclusion: Our extension of crime pattern theory is only tentatively supported. We argue for replication research with larger samples before any firm conclusions are warranted.

The interpretation of research findings based on self-reported delinquency requires knowledge of how response rates depend on the attributes of potential respondents, including their prior offending. The purpose of the present study was to quantify the extent to which, in a sample of offenders, the two main determinants of non-response – non-contact and refusal – depend on prior offending frequency. We used binomial and multinomial regression models to assess whether frequent offenders are more difficult to contact and less willing to participate in online surveys. These hypotheses are tested on a sample of offenders who were invited by regular mail to participate in the Online Activity Space Inventory Survey (OASIS), an online survey on mobility and safety. Controlling for gender and age as potential confounders, our findings do not confirm that frequent offenders are less likely to be successfully contacted, but they do confirm that, if contacted, they are less likely to participate. Response rates in offender-based research are selective and thus potentially biased towards infrequent offenders. They generally favour conservative estimates and conclusions, implying that any associations found between crime and its predictors are likely stronger in reality.

Crime pattern theory predicts that offenders commit offences in their activity spaces. We also propose that they most likely offend in the more frequently visited parts. Previous studies used offenders' residential areas or other activity space proxy measures but lacked data on other routinely visited places (e.g., work, school, and leisure activities). A major contribution of this study is the use of an online survey in which 78 offenders reported on their own activity spaces and committed offences (n = 140). Results show that offending is much more likely in offenders' activity spaces than elsewhere, and effects increase with visiting frequency. Although residential area is a good predictor, offenders' more extensive self-reported activity spaces predict much better where they commit offences.

Wildlife are natural resources utilised by many people around the world, both legally and illegally, for a wide range of purposes. This scoping review evaluates 82 studies nested in 75 manuscripts to provide an overview of the documented motivations and methodologies used, and to identify and analyse knowledge gaps in the motivations of illegal harvesters. Studies differ in what data is collected, often leaving out important contextual variables. We find 12 different motivations, frequently interlinked and multiple often play a role in the same harvesting incident. Motivations seemed to differ between taxa. Future research needs to move beyond a general description but recognise the complexity of the matter and allow for context-specific adjustments to facilitate a deeper understanding of these motivations.

Many studies of wildlife poaching acknowledge the challenges of detecting poaching activities, but few address the issue. Data on poaching may be an inaccurate reflection of the true spatial distribution of events because of low detection rates. The deployment of conservation and law enforcement resources based on biased data could be ineffective or lead to unintended outcomes. Here, we present a rigorous method for estimating the probabilities of detecting poaching and for evaluating different patrol strategies. We illustrate the method with a case study in which imitation snares were set in a private nature reserve in South Africa. By using an experimental design with a known spatial distribution of imitation snares, we estimated the detection probability of the current patrol strategy used in the reserve and compared it to three alternative patrol strategies: spatially focused patrols, patrols with independent observers, and systematic search patterns. Although detection probabilities were generally low, the highest proportion of imitation snares was detected with systematic search strategies. Our study provides baseline data on the probability of detecting snares used for poaching, and presents a method that can be modified for use in other regions and for other types of wildlife poaching.

This open access book draws on an international research project, using extensive and multiple methods to explore unwanted sexual contact and violence in sex work populations. A project delivered by a large team of sex workers, peer researchers, and academics, and with practitioner input over a four-year period, the central question they explore is: how do social, legal, and judicial contexts shape the safety and well-being of people engaging in sex work? The book compares survey and interview data conducted in 2023 across four different legal environments: legalisation (Nevada, USA), criminalisation (Northern Ireland), decriminalisation (New Zealand) and partial criminalisation (UK). It explores how the interaction between legal consciousness (how people in sex work interpret law, consent, their rights, and how or whether to report), legal norms (legal theory, case rulings, legal codes) and legal practices (what police, lawyers, and judges actually do) affects unwanted contact against sex workers. This book advances understanding of the various layers regulating sexual autonomy for marginalised peoples — the specific factors that impact the negotiation, experiences, and disposition of crimes of sexual violence in different socio-legal contexts.

Data Justice and the Right to the City engages with theories of social justice and data-driven urbanism. It explores the intersecting concerns of data justice - both the harms and civic possibilities of the datafied society – and the right to the city - a call to redress the uneven distribution of resources and rights in urban contexts. These concerns are addressed through a variety of topics: digital social services, as cities use data and algorithms to administer to citizens; education, as data-driven practices transform learning and higher education; labour, as platforms create new precarities and risks for workers; and activists who seek to make creative and political interventions into these developments. This edited collection proposes frameworks for understanding the effects of data-driven technologies at the municipal scale and offers strategies for intervention by both scholars and citizens.

Europe has seen an increase in cocaine seizures in recent years. As the criminal landscape in South America has seen noticeable changes, there has been a shift in how cocaine enters Europe. Belgium has become the primary gateway for cocaine trafficking to Europe. With increased cocaine imports, organized criminal gangs have more money to be laundered. This thesis analyzes Belgium's trade data to investigate whether increased cocaine trafficking impacts a country's international trade flow. We propose

a method of detecting money laundering by analyzing trade flows of goods related to money laundering. This is done by introducing the synthetic difference-in-differences method in a case study. We analyze trade flows from 2000 to 2019 between Belgium, tax havens, and cocaine trafficking countries. The thesis finds that as Belgium experiences an increase in cocaine seizures, there is a significant increase in the import of diamonds, arts, and antiquities from cocainetrafficking countries. However, there is no conclusive evidence of increased money laundering activities between Belgium and tax havens. The method cannot conclude the causes of increased imports. However, it can be a tool to narrow down different countries and products to identify trade flows that raise suspicion regarding money laundering activities. Further work should analyze the trade flows identified by the proposed method to detect money laundering.
