A central tenet of the criminal decision-making literature is that perceptions of the environment shape decisions. Yet the underlying mechanisms linking environmental features to perception remain mostly untested. Those that have been tested have relied on methods that are either correlational or have limited generalizability. We aimed to fill this gap by harnessing the power of virtual reality. Using burglary as a case study, incarcerated residential burglars with varying degrees of proficiency (N = 160) explored a virtual neighborhood with houses that differed in features related to the risks and rewards of burglary. In support of our preregistered hypotheses, offenders adjust their perceptions in response to environmental features related to risks and rewards. Moreover, proficiency modifies these perceptions, with more proficient offenders believing they are less likely to get caught and seen and, as a result, more likely to break into a house. We support our statistical findings with rich data from qualitative interviews.

This paper, based on discourse analysis of policy documents, departs from a critique of the juxtaposition of the terms “serious” and “organised” in policies against organised crime in the UK. The conceptualisation of organised crime as national security threat supports our hypothesis that a similar critique can be applied to the emerging narrative of cyber-organised crime in the country. We argue that, whereby organised crime has become essentially “serious” as consequence of its characterisation as a national security threat, cyber crime is becoming “organised” in the policy narrative because of its seriousness. The seriousness and organisation of cyber crime justifies its inclusion within the national security agenda, thus accessing the procedural benefits of criminal intelligence assigned to national security threats. The implications associated to the evolution of such narratives in policy-making need to be assessed while policies are still developing.

An agent-based model is a form of complex systems model that is capable of simulating how the micro-level behavior of individual system entities contributes to macro-level system outcomes. Researchers draw on theory and evidence to identify the key elements of a given system and specify behaviors of agents that simulate the individual entities of that system—be they cells, animals, or people. The model is then used to run simulations in which agents interact with one another and the resulting outcomes are observed. These models enable researchers to explore proposed causal explanations of real-world outcomes, experiment with the impacts that potential interventions might have on system behavior, or generate counterfactual scenarios against which real-world events can be compared. In this review, we discuss the application of agent-based modeling within the field of criminology as well as key challenges and future directions for research.

My interest in criminology grew as the Vietnam War escalated. I applied to two Canadian graduate schools and flipped a coin. The coin recommended the University of Toronto, but I chose the University of Alberta, which had a stronger criminology program. I wrote a dissertation about criminal sentencing, which led to an Assistant Professorship at the University of Toronto. Dean Robert Pritchard of Toronto’s Law School encouraged my work and later successfully nominated me for a Distinguished University Professorship. My interests continued to grow in international criminal law. A MacArthur Distinguished Professorship at Chicago’s Northwestern University and the American Bar Foundation facilitated my research at the Tribunal for the Former Yugoslavia. I followed this by studying the crime of genocide in Sudan and later the trial of Chicago’s Detective Jon Burge. Burge oversaw the torture of more than 100 Black men on Chicago’s South Side. US Attorney Patrick Fitzgerald prosecuted Burge when Illinois prosecutors would not. Despite many good things about Chicago, the periodic corruption of the government and police was not among them.

This study validates two risk assessments designed to predict inmate misconduct in New Mexico prisons. Using a six-year admission cohort of inmates admitted to New Mexico prisons between 2015 and 2021 (n = 34,2467 unique classification events), we paired focus groups with New Mexico Corrections Department classification staff and observations of the classification process with logistic regression, count models, and random forest models to assess the predictive validity of the New Mexico Corrections Department (NMCD)’s initial and reclassification tools for general and serious, violent misconduct within six months following classification. Results from focus groups and observations highlighted that the NMCD had the essential components of an objective classification system. Our empirical validation found that the reclassification tool was more predictive of misconduct than the initial classification tool for both male and female inmates and generally had good classification performance, though there were limitations with the metric we used for evaluating predictive validity. We also recommended that some factors on the classification tools should be rescored based on their predictive relationship with serious violent misconduct and proposed an updated scoring system based on these relationships (i.e., increasing points for factors which were more predictive of violent misconduct). We also evaluated the relationship between overrides, custody levels, and misconduct.

Identity or self-concept has long been theorized to explain rule-violating behavior. Life-course criminology scholarship has incorporated identity as a core concept explaining desistance or disengagement from crime over time. Individuals who transform their identities from anti to prosocial or who are ready to move away from their past selves are more likely to desist from crime. However, the role of identity, particularly the forms of identity that have been theorized to influence desistance, has been understudied with respect to prison behavior. Understanding the ways in which identity relates to prison misconduct may help inform prison programming as well as theoretical perspectives drawing on the concept. The purpose of this study is to explore how various forms of identity are related to future prison misconduct, controlling for past misconduct and a host of other theoretical variables, in Minnesota prisons. The results indicate that two forms of identity, replacement self and cognitive transformation, are related to general misconduct but not violent misconduct in survival models. For general misconduct, both forms of identity are associated with a reduction in the risk of new convictions. Implications for theory and practice are discussed.

While specific responsivity factors are believed to either inhibit or facilitate successful involvement in programming, relatively little attention has been given to the validation of responsivity assessments used for correctional populations. Based on a sample of nearly 2,100 individuals confined in Minnesota prisons, this study examines the relationship between a needs and responsivity assessment system and multiple measures of program participation, dosage and completion. The responsivity domains—childhood trauma, mental health, religiosity, motivation and learning style—were significantly associated with at least one measure of programming. All but two of the needs domains also had a significant association with programming involvement. We discuss the implications of the findings for correctional research and practice.

This report analyzes COVID-19 impacts on criminal justice data. Specifically, it focuses on the differences amongst adult and juvenile arrests, adult sentencing and juvenile dispositions, adult and juvenile carceral admissions between 2020 and previous years. This type of analysis can help support state and federal policymakers in determining potential next steps in addressing the pandemic’s impact on the criminal justice system – both in the short-term and in the long-term. This report will also help future researchers better understand the anomalies and a more accurate assessment of the pandemic that occurred in the criminal justice datasets during the years impacted. The Washington Statistical Analysis Center (SAC) applied for and received the 2021 State Justice Statistics Grant from Bureau of Justice Statistics (BJS). Among other projects, the SAC sought the grant to evaluate the impact of COVID-19 on criminal justice data. Main conclusions from this report: 1. Overall, counts of arrests in Washington State, regardless of category, showed mixed findings with increased from 2017 to 2018 and then 2019 to 2020; but decreased from 2018 to 2019 and then again 2020 to 2021. From 2020 to 2021, there was an overall 3% decrease in arrests in Washington State. 2. For adult arrests in Washington State, from 2019 to 2020 and then 2020 to 2021, there was an overall 17.8% and 13.9% decrease, respectively. For juvenile arrests, from 2019 to 2020 and then 2020 to 2021, there was an overall 39.1% and 33.2% decrease, respectively. 3. Superior court filings decreased from 16.2% in 2018-2019, to 21.4% in 2019-2020, to 15.7% in 2020-2021. Additionally, felony jail sentences decreased throughout the years, from 2017 to 2021. Furthermore, while the overall average prison sentences also saw a decrease from 2017 to 2021, in 2019 to 2020, murder, sex crimes, robbery, and drug crimes saw rises. 4. Juvenile dispositions showed substantial decreases from 2019 to 2020 and from 2020 to 2021 by 7.3% and by 28.8%, respectively. 5. Adult prison admissions saw a decline in all admissions (new, re-admit, and other) . from 2019 to 2021 6. From 2019 to 2020,DOC juvenile admissions and new admissions increased by 126.9% and 11.7%, respectively. 2020 to 2021 presented with decreases in all juvenile admissions.

This report analyzes COVID-19 impacts on criminal justice data. Specifically, it focuses on reported National Incident-Based Reporting System (NIBRS) offenses and Washington Association of Sheriffs and Police Chiefs (WASPC) arrests and bookings. This type of analysis supports state and federal policymakers to determine the actions needed to address the pandemic’s impact on the criminal justice system. This will also help future researchers define the anomalies that occurred in the criminal justice datasets, specifically the longitudinal studies that include the years impacted by COVID-19. Researchers can provide a more accurate assessment of the impact that the pandemic may have on the criminal justice system and its associated datasets. The Washington Statistical Analysis Center (SAC) applied for and received the 2021 State Justice Statistics Grant from Bureau of Justice Statistics (BJS). Among other projects, the SAC sought the grant to conduct this report to evaluate the impact of COVID-19 on criminal justice data. Main conclusions: 1. There was a decrease in 2018 to 2019 (3.0%) and 2019 to 2020 (9.3%) in NIBRS incidents reported. 2. There was a decrease in 2018 to 2019 (0.5%) and 2019 to 2020 (19.1%) in WASPC arrests. 3. There was a decrease in 2018 to 2019 (24.7%) and 2019 to 2020 (12.4%) in WASPC bookings.

The global 2020 coronavirus pandemic has had an unprecedented impact on the operations and actions of local, state, and national governments across all areas of criminal justice. The unique characteristics of this pandemic trend toward short- and long-term consequences as significant changes to criminal justice and legal outcomes. To respond to these impacts, the Washington Statistical Analysis Center (SAC) applied for and received the 2022 State Justice Statistics (SJS) grant from the Bureau of Justice Statistics (BJS). The SAC sought the grant to increase access to statistical data and create new metrics and indicators to enhance the integrated criminal justice database — the Justice Data Warehouse (JDW) — in efforts to strategically and analytically evaluate the pandemic’s impacts in criminal justice. Through this grant, the Washington SAC leveraged and built upon the JDW to expand the data variables by creating COVID-19 metrics and indicators to help assess and account for COVID-19 impacts in the criminal justice and legal system.

The distinct setting in which cyber-dependent crime takes place may reduce the similarity in the deviance of social network members. We test this assumption by analysing the deviance of the most important social contacts of cyber-dependent offenders and traditional offenders in the Netherlands (N = 344 offenders; N = 1131 social contacts). As expected, similarity in deviance is weaker for cyber-dependent crime. Because this is a strong predictor of traditional offending, this has important implications for criminological research and practice. Additionally, for both crime types the offending behaviour of a person is more strongly linked to the deviance of social ties if those ties are of the same gender and age, and if the offender has daily contact with them. Implications and future criminological research suggestions are discussed.

Objectives: Building on Hägerstrand’s time geography, we expect temporal consistency in individual offending behavior. We hypothesize that repeat offenders commit offenses at similar times of day and week. In addition, we expect stronger temporal consistency for crimes of the same type and for crimes committed within a shorter time span. Method: We use police-recorded crime data on 28,274 repeat offenders who committed 152,180 offenses between 1996 and 2009 in the greater The Hague area in the Netherlands. We use a Monte Carlo permutation procedure to compare the overall level of temporal consistency observed in the data to the temporal consistency that is to be expected given the overall temporal distribution of crime. Results: Repeat offenders show strong temporal consistency: they commit their crimes at more similar hours of day and week than expected. Moreover, the observed temporal consistency patterns are indeed stronger for offenses of the same type of crime and when less time has elapsed between the offenses, especially for offenses committed within a month after the prior offense. Discussion: The results are consistent with offenders having recurring rhythms that shape their temporal crime pattern. These findings might prove valuable for improving predictive policing methods and crime linkage analysis as well as interventions to reduce recidivism.

This open access book critically revisits 30 years of debate surrounding the evolution of crime trends, aiming to reconcile various hypotheses and controversies. It scrutinizes the concept of the "crime drop," highlighting the methodological pitfalls in understanding the causation mechanisms behind this phenomenon. By examining the impact of information and communication technologies (ICT) on daily routines and crime, the book challenges traditional notions of crime reduction. Drawing on extensive examples, data from official and non-official statistics, and crime surveys, this book illustrates how cyberspace has fundamentally reshaped the nature of crime. Despite this transformation, integrating cybercrime into conventional crime statistics remains an unaccomplished task. The book offers a thorough methodological discussion on measuring cybercrime, addressing the challenges researchers face in quantifying and explaining crimes committed both in cyberspace and across physical and digital boundaries. This book speaks to students, academics, researchers, and practitioners in the fields of criminology, criminal justice, and cybercrime. It is an invaluable resource for anyone seeking to understand the complexities of modern crime trends and the challenges posed by the digital age.

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.

This paper reviews and distills a wide array of recent social science literature and offers an evidence-based vision for how public safety can be maintained while relying less on the use of incarceration. We offer the following lessons from the literature. First, while interventions that increase economic opportunities have been shown to be effective in reducing criminal behavior, particularly income generating crime, interventions which change how people think appear to be even more effective at reducing the types of crimes that most frequently lead to incarceration. Second, a wide variety of investments targeted towards children in disadvantaged neighborhoods appear to be effective and likely pay for themselves over time. Third, while there is a natural concern that diverting criminal defendants from traditional prosecution will erode the deterrence value of criminal sanctions, the evidence suggests that for first-time and younger offenders, individuals who have been diverted – either through a formal program or informally via “non-prosecution” – tend to be less likely to be rearrested in the future. Fourth, the evidence suggests that law enforcement can play an important role in reducing the use of incarceration when police are visible and engage in high-value activities that deter crime or focus their arrest powers more intensively on violent and/or high-volume offenders; in doing so, they have the ability to reduce crime through deterrence and focused incapacitation without increasing the footprint of the justice system. Finally, there is potential to meaningfully reduce incarceration levels through sentencing reforms without compromising public safety – so long as the reforms are structured in such a way as to target the least criminally productive offenders, while retaining in custody those offenders who are most likely to commit the costliest offenses or who are likeliest to offend in high volumes.

This paper offers experimental evidence that crime can be successfully reduced by changing the situational environment that potential victims and offenders face. We focus on a ubiquitous but surprisingly understudied feature of the urban landscape – street lighting – and report the first experimental evidence on the effect of street lighting on crime. Through a unique public partnership in New York City, temporary streetlights were randomly allocated to public housing developments from March through August 2016. We find evidence that communities that were assigned more lighting experienced sizable reductions in crime. After accounting for potential spatial spillovers, we find that the provision of street lights led, at a minimum, to a 36 percent reduction in nighttime outdoor index crimes.

Background: The ongoing overdose crisis in Canada has prompted efforts to increase access to a “safer supply” of prescribed alternatives to the unregulated drug supply. While safer supply programs predominantly distribute hydromorphone tablets, the Safer Alternatives for Emergency Response (SAFER) program in Vancouver, Canada offers a range of prescribed alternatives, including fentanyl patches. However, little is known about the effectiveness of fentanyl patches as safer supply. Drawing on the perspectives and experiences of program participants, we sought to qualitatively evaluate the effectiveness of the SAFER fentanyl patch program in meeting its intended aims, including reducing risk of overdose by decreasing reliance on the unregulated drug supply. Methods: As part of a larger mixed-methods evaluation of SAFER, semi-structured qualitative interviews were conducted with 17 fentanyl patch program participants between February 2022 and April 2023. Thematic analysis of interview data focused on program engagement, experiences, impacts, and challenges. Results: The flexible program structure, including lack of need for daily dispensation, the extended missed dose protocol, and community pharmacy patch distribution fostered engagement and enhanced autonomy. Improved management of withdrawal symptoms and cravings due to steady transdermal dosing led to reduced unregulated drug use and overdose risk. Participants also experienced economic benefits and improvements in overall health and quality of life. However, skin irritation and patch adhesion issues were key barriers to program retention. Conclusion: Our findings demonstrate the value of including fentanyl patch safer supply in the substance use continuum of care and offer insights for innovations in delivery of this intervention.

Since 2021, the Swedish National Council for Crime Prevention (Brå) has been commissioned by the Government with evaluating the initiative for 10,000 more police employees. The initiative aims to increase the number of police employees by 10,000 over the period 2016-2024 (Ju2021/02238). This is the third interim report under the assignment and focuses specifically on the investigative activities. The overarching purpose of the report is to analyse staff development and investigative results in the police's work with serious crime, especially serious crimes related to organised crime, and crime against particularly vulnerable victims during the period 2018-2023. In the study, Brå uses the Police Authority's personnel statistics and case data, interviews with heads of units and investigators, as well as a survey on the current staffing situation in the police districts’ investigative sections. In the analyses of case data, we also use the Police Authority's complexity measure, which was developed with the purpose of weighting cases according to how resource-intensive (complex) they are. The higher the value of the complexity measure (Kvalue) a case has, the more resources it requires. Delimitations In terms of staff development, the study is limited to focus specifically on Serious Crimes Investigative Units (SCUs), which are on the police district and regional organisational level, and on Domestic Violence Investigative Units (DVIUs), which are on the police district level. Investigative activities at local police district level are covered to a limited extent, and activities at national level are not included in the study at all. Trends in the inflow of cases and investigation outcomes focus on three overarching categories of offences. The first two categories, serious crimes and serious crimes related to organised crime (a subset of serious crimes), were identified empirically based on the types of crime that, according to the list of offences, shall be investigated at the police district level and are usually investigated by the SCUs. These categories include for example homicide (with or without the use of firearms), extortion, violence against a public official (police officer), arson, destruction causing public endangerment by explosion (hereafter referred to as explosions) and serious weapons offence. The fact that we selected the types of crime that the SCUs normally investigate is a delimitation that Brå has had to make in order for the study to be manageable in its scope. By including explosions and homicides with firearms, which are two of the most resource-intensive types of crime in terms of investigation, we believe that the study captures a key part of the police's investigative activities in relation to serious crime and serious organised crime. The third category, crimes against particularly vulnerable victims (SUB crimes), is the collective name for the offence code groups crimes against children, crimes in close relationships and rape against adults. This study includes those SUB crimes that, according to the list of offences, shall be investigated at police district level and are usually investigated by

the DVIUs. In addition, the study covers, to a limited extent, the investigative activities at the level of local police districts and their investigation of volume crimes, which are less complex and common types of crime such as theft, assault, and minor drug offences. The main outcome used to measure investigative performance is the proportion of cases reported to prosecutors out of all closed cases involving a preliminary investigation, which we refer to as clearance rate. Some analyses also present the number of cases reported to prosecutors. More employees in the investigative activities Within the investigative activities as a whole, the number of employees has increased by 2,900 (36%) over the period 2018-2023. However, staff growth is not evenly distributed across organisational levels, but is significantly higher at police district and regional level than at local police district level. Increased inflow of cases and high number of staff on temporary loan in Serious Crimes Over the period 2018-2023, the total inflow of serious crimes has increased by almost 30 per cent, both in terms of the number of cases and their complexity (K-value). However, the number of serious crime cases handled by the specialised Serious Crimes Investigative Units (SCUs) has remained relatively unchanged over time, while the K-value has increased. This development indicates that less complex cases have been removed from the SCUs, while a larger part of their inflow consists of the most complex serious crimes. The clear discrepancy between the increase in total inflow of cases (30%) and the unchanged inflow to the SCUs also suggests that a large and increasing number of serious crimes are handled in other parts of the organisation. This is also reflected in the increasing number of serious crime cases handled by local police districts. The number of serious crimes investigated by local police districts has increased by more than 80 per cent since 2018. Police Region Stockholm is the main driver of this development. There, the number of serious crimes investigated by local police districts has increased by almost 300 per cent. The number of employees in the SCUs has increased by 250 people, just over 30 per cent, between 2018 and 2023. The increase in staff took place mainly at the beginning and end of the period studied. Police Region Stockholm stands out with a significantly lower staff growth than the other regions (7%). Police Region Mitt has also experienced relatively low growth (17%). Growth is highest in Police Region Bergslagen (75%). Despite large regional variations, the overall picture is that despite the increase in staff, the specialised SCUs have not been able to cope with the increased influx of serious crimes. The staffing survey of the investigative sections also shows that the teams have difficulty managing the influx of cases themselves. According to the survey, almost a quarter of the SCU's staffing consists of temporarily borrowed staff.

In this report, the Swedish National Council for Crime Prevention (Brå) presents a government assignment regarding facilitators in the legal sector who provide assistance to criminal networks. For the purposes of this report, a facilitator is defined as someone misusing his or her position or mandate in local government or the public or private sectors in order to benefit criminal networks. Our research is based on analyses of interviews, cases and encrypted chat messages from members of criminal networks. Our study broadly confirms previous findings from Swedish and international research, particularly with regard to the tasks performed by facilitators. This report also presents a broader and more comprehensive picture of the conditions in Sweden. Unique data also provides us insight into areas not previously described.

What tasks do facilitators perform? Our study suggests that many members of criminal networks appear to have a substantial interest in using facilitators. Access to such facilitators is limited, but they can be found in all studied sectors. These mainly include the criminal justice system, numerous local government administrations, banking and finance, real estate, incorporation, bookkeeping and accounting services, legal services, security and surveillance, and transport. Overall, the identified cases occur in most regions of Sweden. This is therefore not solely a metropolitan phenomenon. The degree of activity among the identified facilitators ranges from sporadic, brief assistance to long-term and frequent assistance provided to numerous members of different criminal networks. The material as a whole shows that, in some areas, facilitators are more likely to assist criminal networks. Such professionals have frequent contacts with criminal actors, are exposed to threats or other pressure to a significant degree or receive remuneration that is tied to their number of clients. Facilitators mainly provide information to members of criminal networks, which is in line with previous studies. This information can be of very different kinds, including sensitive personal data, information about what public authorities or municipalities know about a criminal network, or more strategic information regarding potential criminal activity. Such information may also consist of warnings or instructions relayed to the criminal network from detained or imprisoned members. Such information allows them to coordinate their testimony and complicate investigations. One important observation is that information sought from facilitators need not be secret to be valuable. Rather, accumulated information and insider knowledge makes such information sensitive and useful to members of criminal networks. Professionals also facilitate logistics by smuggling, transporting or storing illegal goods. Facilitators may also create legitimate covers by generating credible documentation or certificates, or by providing companies which are used to commit crimes, as well as by identifying criminal schemes which appear as legitimate business activity. In some cases, facilitators are also needed to handle criminal proceeds, which public anti-money laundering measures have made more difficult for criminal networks. Finally, some facilitators even issue favourable decisions - they deviate from procurement procedures or other important decisions, fail to report crimes, or facilitate improper payments from welfare systems or the private sector. Our survey shows the facilitators are asked to perform a broad array of tasks of varying complexity. These range from logistical tasks, which the criminal network might have performed on its own or learned, to complex assignments which only a facilitator could perform, especially influencing the outcome of certain decisions and accessing sensitive information.
