This study examines changes in risk and protective factors among youth on probation (N=6,997) and how services received relate to these changes and subsequent recidivism. Using standardized risk assessments at intake and exit, logistic regression models assessed changes in risk and protective subscales, the relationship between specific services and observed changes, and associations with rearrest and reconviction. Overall, youth showed reduced risk and increased protective scores during probation. Increases in treatment, restitution, and assessments were linked to risk reductions, while treatment, assessments, and skill-building services were associated with gains in protective factors. Notably, more treatment services corresponded with increased risk in the school domain. Youth of color were less likely to experience a decrease in risk and an increase in protective scores. Increases in protective school scores and treatment services were linked to lower odds of rearrest and reconviction. In comparison, more monitoring services and increased legal history were associated with higher odds of recidivism. Findings highlight the potential of rehabilitative services to support youth success and suggest compliance based approaches, such as increased monitoring, may undermine outcomes. The study underscores the need for equitable, developmentally appropriate, and supportive interventions in juvenile probation.

This paper studies the impact of birthright citizenship on youth crime. We leverage a reform which automatically granted birthright citizenship to eligible immigrant children born in Germany after January 1, 2000 and administrative crime data from three federal states. Immigrant youth who acquired citizenship at birth are substantially less likely to engage in criminal activity, with estimates indicating a 70% reduction. These results are particularly relevant in light of ongoing debates in the U.S. about abolishing birthright citizenship. Our findings suggest that inclusive citizenship policies can reduce crime and its associated costs, which in turn could strengthen social cohesion.

Cross-border parental child abductions in the EU are governed by The 1980 Hague Convention on the Civil Aspects of International Child Abduction and (except for Denmark) the Brussels II-ter Regulation. Countries outside of the EU may or may not be Contracting States to ‘the Convention’, but will not be bound by Brussels II-ter. Research has found that the often negative, long-lasting impact of abduction may continue throughout the lifecycle of those who have been abducted. It may also affect future generations of society. This means that every effort to deter abduction should be made. Where that is not possible, the 1980 Hague Child Abduction Convention should be nurtured to support its application in contemporary society. Specialist mediation should be encouraged in relation to international child abduction generally, and specifically in relation to Third Countries which are not Contracting States to ‘the Convention’. This study was commissioned by the European Parliament’s Policy Department for Citizens’ Rights and Constitutional Affairs at the request of the JURI Committee.

The briefing, funded by the Barrow Cadbury Trust, examines what happens as exploited children turn 18, exploring how responses across safeguarding and criminal justice fail to keep pace with ongoing risk and harm. It sets out principles and practical steps to ensure protection continues into young adulthood and to prevent the unjust criminalisation of victims.

While awareness of CCE has grown, responses for children remain inconsistent and are too often led by punishment. At 18, those weaknesses are magnified. Support frequently falls away, thresholds for help rise, and young adults are more likely to be treated as perpetrators than recognised as victims. As parliament considers the Crime and Policing Bill’s new offence of child criminal exploitation (CCE), there is a critical opportunity to improve the response for victims – but a growing risk that exploited young adults will be prosecuted as perpetrators.

The briefing is informed by an evidence review and consultation with professionals, legal practitioners, academics, civil servants, and sector experts and identifies several urgent issues:

Youth arrests and incarceration increased dramatically in the closing decades of the 20th century but have fallen sharply since. Public opinion often wrongly assumes that crime (and incarceration) is perpetually increasing. In fact, the 21st century has seen significant declines in both youth arrests and incarceration. Despite positive movement on important indicators, far too many youth—disproportionately youth of color—are incarcerated. Nevertheless, between 2000 and 2023, the number of youth held in juvenile justice facilities, adult prisons, and adult jails fell from 120,200 to 31,800—a 74% decline.

Gaming is now the most profitable form of entertainment worldwide, with over 3.42 billion people playing some form of games, accounting for a market of $187.7 billion engaging across consoles, PCs, and mobile devices.1 Nearly nine in ten children in middle and upper-income countries play online games2 . While online multiplayer games foster social connection, creativity, and communitybuilding, they are also increasingly exploited by violent organizations, ranging from non-state armed groups in conflict-affected settings to hybrid criminal networks. These actors use gaming spaces to propagandize, groom, recruit, and organize, leveraging gaming platforms' social and technical features to target children and young players. This policy brief examines how gaming ecosystems are being exploited to socialize and recruit children to participate in organized violence and provides recommendations for policymakers, practitioners working with children, and the gaming industry to safeguard children in online gaming environments. Online gaming is neither inherently harmful nor a direct cause of violence, but its social and technical infrastructure is being exploited at scale by malign actors. 3 Indeed, as the American Psychological Association framed the issue in a 2020 resolution, “attributing violence to violent video gaming is not scientifically sound and draws attention away from other factors.”4 At the same time, specific harms are affecting children via online gaming today. To protect children and young players, industry leaders, regulators, law enforcement, and practitioners working with children must act now, establishing robust prevention, detection, and response strategies that ensure children can enjoy their right to play and their right to be protected from violence. Gaming’s prosperous future depends on ensuring its spaces remain safe, inclusive, and free from children being targeted by violent actors and organizations. This report provides a series of recommendations to help achieve that aim.

In this paper we focus on how the criminal history of a household affects juvenile reoffending. Using detailed administrative data from Greater Manchester Police for 2007-2018, we construct a matched sample of 15,548 juvenile first-time offenders. We show causally that juveniles from a household with a previous criminal record are 26.4 to 29.8 percentage points more likely to reoffend within three years, with the greatest additional risk being in the first year after the initial offence. We show that social learning, co-offending by siblings, and differential processing contribute to this effect. Our findings highlight household criminality as an important driver of criminal persistence, underscoring the need to move beyond individual-level predictors and address the criminogenic dynamics within the home.

The youth justice system was created because youth are different from adults.1 State departments of juvenile justice have purpose clauses affirming that rehabilitation is their primary goal. In the youth justice system, youth have access to developmentally appropriate services that are not available in the adult criminal legal system. Sending youth to the adult criminal justice system, for any offense, harms youth wellbeing and community safety.

Miller v. Alabama and Montgomery v. Louisiana restricted states’ ability to impose life without parole for youth under age 18 (henceforth JLWOP). Since Miller, 46 pieces of legislation across 34 states and the District of Columbia have altered JLWOP sentencing policies. The current study provides the first comprehensive and scientific review of this legislation. Using policy surveillance as a methodological guide, we found that a majority of statutes (N = 28) ban JLWOP sentencing, above and beyond the Supreme Court's requirement. Many statutes also extended sentencing reforms and post-conviction relief eligibility to other types of sentencing beyond JLWOP. However, all but one statute still allows either JLWOP or life with parole as a sentencing option for minors convicted of homicide crimes and requires between 15 and 40 years, at minimum, to be served before being eligible for release. Grounding our analysis in institutional theory, we argue that the relative punitivity of the JLWOP reforms enacted was associated with measures of JLWOP institutionalization across states (i.e., pre-Miller JLWOP population and pre-Miller sentencing schema), suggesting that states where JLWOP was more routinely used were more resistant to policy reform.

Policy Implications

The current study provides implications for future decarceration efforts. Findings suggest that state legislatures are willing to enact post-conviction relief measures (e.g., judicial review or “second look” measures) for individuals convicted of violent crimes to address over-incarceration, deviating from previous decarceration efforts focused on non-violent, low-level offenses. In spite of the promising window for juvenile justice reform that Miller provided, however, these reforms have taken a relatively modest, incremental approach toward altering extreme youth sentencing practices in the United States. Policy makers and advocates seeking to promote sentencing reform efforts should factor in how highly institutionalized a sentencing practice is in each state, as this might inform effective strategies for policy change.

Background

Mexico rolled out state-led criminal justice reforms between 2000 and 2017 to modernize procedures and improve rule of law. Whether these changes reduced violent crime—especially in cartel-affected areas—remains uncertain.

Aims

Estimate the impact of reform implementation on homicides and arrests, and assess mechanisms related to enforcement capacity and public cooperation with law enforcement.

Materials & Methods

We build a municipality–year panel (2000–2017) from death certificates (homicides) and administrative records (arrests). Because states adopted reforms at different times, we use difference-in-differences estimators designed for staggered adoption and heterogeneous treatment effects, with rich fixed effects and controls. To probe mechanisms, we analyze nationally representative survey measures of crime reporting, institutional trust, and perceived police/prosecutorial integrity.

Results

Reform implementation is associated with a ~25% increase in homicide rates. Over the same horizon, arrest rates fall by >50%. As homicides are less prone to underreporting than other crimes, the homicide increase is unlikely to be a reporting artifact. Survey evidence shows reduced crime reporting, declining trust in institutions, and more negative views of police and prosecutors; effects are strongest in cartel-affected regions.

Discussion

The pattern is consistent with an erosion of effective enforcement capacity at rollout: fewer arrests and lower public cooperation raise expected returns to violent crime. In high-violence settings, reforms that change procedures without parallel boosts to investigative and prosecutorial capacity—and without safeguards for witnesses—can weaken deterrence.

Conclusion

Mexico’s staggered judicial reforms coincided with higher homicides and sharply lower arrests. Successful reform in violent contexts likely requires coordinated institutional strengthening (policing, prosecution, witness protection), phased implementation with measurable benchmarks, and strategies to sustain public trust and reporting.

This qualitative study examines how frontline police officers in British Columbia experienced and adapted to Canada's first formal drug decriminalization policy 1 year after implementation. Drawing on 30 semi-structured interviews and using thematic analysis with a policy alienation and street-level bureaucracy lens, we analyzed how officers felt alienated from the policy process and coped with this experience as frontline implementers. Key themes show that frontline officers experienced processes of policy alienation in various ways: they felt that the policy was misaligned with their frontline perspectives; the Policy undermined their ability to help people in their communities; and legal ambiguity surrounding the Policy was challenging to navigate. Their coping strategies revealed that officers interpreted and executed decriminalization in divergent ways.

Policy Implications

These findings have important implications for policymakers and police leadership considering drug policy reforms. Officers’ feelings of disempowerment and policy meaninglessness, especially in contexts of legal ambiguity, may lead to inconsistent or inequitable enforcement. Strengthening communication across police ranks is critical. Middle managers may help translate reform goals, identify resource gaps, and support effective coping strategies. Legal clarity should extend beyond policy updates to help officers reconcile overlapping laws and reduce liability concerns. While there are limits to policy consultation with frontline officers within the hierarchical structure of police institutions, reform efforts should still engage with frontline officers’ working logics. Training should address harmful attitudes and misunderstandings of drug use, clarify legal boundaries, and mitigate unintended harms of enforcement. Ultimately, effective drug policy reform in a multi-jurisdictional system requires acknowledging how frontline officers interpret and shape

Street crimes are thought to be inBy John M. MacDonald, Aaron Chalfin, Maya Moritz, Brian Wade, Alyssa K. Mendlein, Anthony A. Braga, Eugenia South

Street crimes are thought to be influenced by changes in ambient lighting; yet, most studies have focused on small-scale interventions in limited areas. It remains unclear whether enhanced lighting can improve safety on a larger, jurisdiction-wide scale. This study examined the first 10 months of Philadelphia's citywide rollout of enhanced street lighting. Between August 2023 and May 2024, 34,374 streetlights were upgraded across 13,275 street segments, converting roughly one third of the city's street segments to new LED (light-emitting diode) fixtures that provide clearer and more even lighting. We assessed the impact of these upgrades on total crimes, violent crimes, property crimes, and nuisance crimes. Our findings reveal a 15% decline in outdoor nighttime street crimes and a 21% reduction in outdoor nighttime gun violence following the streetlight upgrades. The streetlight upgrades may have contributed to 5% of the citywide decline in Philadelphia gun violence during the study period. Qualitative data also suggest that resident perceptions of safety and neighborhood vitality improved after new streetlights were installed.

Policy Implications

Although prior research has mostly focused on small-scale implementations, our study demonstrates that improvements in street lighting can significantly reduce crime rates across large urban areas. These results support the adoption of energy-efficient LED street lighting as a crime reduction strategy for cities. Further research is needed to explore the impact of enhanced streetlight interventions on other types of crime and to determine whether the crime reduction benefits are sustained when these upgrades are implemented across the entire City of Philadelphia for an extended period

Italy’s illegal commercialised sex industry is estimated to be worth 90 million Euro and involves up to 9 million clients annually. The industry depends on migrants from Nigeria, Romania and Albania, many of whom are victims of human trafficking, abuse, exploitation, oppression, extreme educational and economic poverty, and non-integration in Italy. But despite legal and policy interventions, sexual exploitation of migrants is highly tolerated, goes largely unpunished and is increasingly threatening to migrant women's wellbeing throughout the peninsula, as in the case of migrant women from Nigeria. This brief focuses on the NigerianItalian HTSE for two main reasons: (a) Italy’s proximity to the central Mediterranean route serving as key irregular route for migrant smugglers and human traffickers; (b) Italy’s dysfunctional and emergencial asylum systems coupled with its insufficient, untimely and inefficient policy intervention on migrants' sexual exploitation, and; (c) perceptions and misinformation about Europe as source of economic and social opportunities and prestige, which all provide a fertile ground for mafia activities and organised crime to flourish. Therefore, coupled with PERCEPTIONS findings, this brief draws political attention to the intersections between irregular migration and asylum, mafia activities and organised crime, targeted deception and misinformation, abject poverty and traditional practices within the discourse of NigerianItalian HTSE.

This report, Climate Chains: Mapping the Relationship between Climate, Trafficking in Persons and Building Resilience in the Philippines, explores the complex links between climate change, livelihood, vulnerability, migration and human trafficking in the Philippines. Commissioned by IOM under the Climate Resilience Against Trafficking and Exploitation (CREATE) project, this study forms part of a broader research focusing on Ethiopia and the Philippines – two countries facing distinct climate challenges: slow-onset droughts and sudden-onset typhoons, respectively.  

The research used a mixed-methods approach including household surveys, interviews and focus group discussions. The report puts forward a conceptual model that links climate events and trafficking through a series of intertwined steps. It identifies a causal chain where climate events disrupt livelihood, increase vulnerability and heighten migration intentions, which can lead to exploitation and trafficking. The research explores how factors linking climate and trafficking operate in the Philippines. 

This study provides critical insights and recommendations for policymakers, donors and organizations in the Philippines and internationally that are working to combat human trafficking and exploitation, while strengthening resilience to climate change

Chad’s role as a departure and transit country for northbound migration to North Africa and Europe is often overlooked, particularly in comparison to neighbouring Niger and Sudan. However, the country’s position at the crossroads of routes connecting central and eastern Africa to Libya and Niger makes it a significant transit corridor for regional migration, and its role as a bastion of relative stability in an increasingly volatile region has further increased its importance in recent years. Since 2023, the conflict in Sudan and a major influx of refugees into Chad have further shaped these mobility dynamics, making the country a major destination and transit point for Sudanese refugee displacement in the region. At the same time, Chad is navigating a fractious and contested political transition. Political violence escalated in 2024 and remains an important source of tension and political instability. The combination of these complex internal and regional dynamics, and their impact on human smuggling dynamics, make Chad a key country to monitor. A major component of human smuggling dynamics in Chad is internal movements to the country’s northern goldfields. These mobility patterns have typically been shaped by internal factors, including political instability, rebel activity and gold mining.1 This changed in 2023 with the outbreak of the conflict in Sudan and the massive influx of refugees and returnees into eastern Chad. Though northbound movements were temporarily hindered by this shift, which resulted iI emerged as the dominant model of migration in Libya in 2021 and remained so in 2024. Hybrid smuggling refers to the system whereby migrants initially travel to Libya through regular or semi-regular routes, such as flights into airports, and then are moved overland to coastal departure points for the sea crossing to Europe. This system is adaptable to local changes and delivers a consistently high level of attempted departures, despite some localized improvements in security. Critically, the Government of National Unity (GNU), which rules western Libya, continued to struggle with internal division and weak control over crucial areas, especially on the west coast, a key region for human smuggling stretching from the Tunisian border to the city of Zawiya.

  Background - The domestic abuse core outcome set (DVA-COS) is an agreed set of five outcomes intended for use in evaluations of interventions or services for children and families with experience of domestic violence and abuse (DVA, hereafter referred to as domestic abuse). A COS is a minimum standard for measurement in intervention studies, the purpose of which is to overcome heterogeneity in outcome selection and measurement. The aim of a COS is to maximise the value of a body of evidence by facilitating comparison between and synthesis across studies, thus reducing research wastage. Since the development of the DVA-COS, work has been undertaken to identify, select, and validate outcome measurement instruments (OMIs) to measure the core outcomes. The Warwick– Edinburgh Mental Wellbeing Scale (WEMWBS) was previously identified as acceptable by stakeholders to capture two outcomes: child and caregiver emotional health and wellbeing. This work seeks to extend those findings by validating the measure for use with domestic abuse experienced populations. Aims Foundations, the national What Works Centre for Children & Families, commissioned two work packages to develop and integrate previous work to outline and validate OMIs for use to assess outcomes comprising the DVA-COS. Work package 1 seeks to identify three OMIs, and this report focuses on work package 2, which aimed to validate the Short WEMWBS (SWEMWBS) for use with children and young people (aged 11 to 18) who have experienced domestic abuse. The studies that make up this work package used mixed methods to examine the acceptability, content validity, structural validity, internal consistency, and measurement invariance for the scale in children and young people experiencing domestic abuse. We also report a validation study of the WEMWBS for adults with experience of domestic abuse. Methods The above aims were addressed across four individual studies: two planned and two supplementary. First, a qualitative ‘think aloud’ study assessed the acceptability of the SWEMWBS with children and young people who had experienced domestic abuse. The remaining three studies were quantitative analyses of secondary data on using the SWEMWBS and WEMWBS with children and young people and adult samples. • Study A: a qualitative think aloud study that involved interviews and a focus group to gather feedback from children and young people with domestic abuse experience on use of the SWEMWBS. • Study B: examined cross-sectional data collected by the OxWell Student Survey to validate the SWEMWBS with children and young people affected by domestic abuse. • Study C: examined anonymised longitudinal service data to validate the SWEMWBS with children and young people affected by domestic abuse. • Study D: validated the WEMWBS with adults who have experienced domestic abuse using cross-sectional data from the Adult Psychiatric Morbidity Survey (APMS). Key findings Our findings demonstrate the validity and acceptability of the SWEMWBS and WEMWBS in domestic abuse-experienced child and adult populations respectively. Study A indicated that the SWEMWBS is broadly acceptable for use with children and young people, while raising important considerations regarding respondents’ interpretation of the measure’s items as well as the emotional impact of the measure on this population. Studies B and C demonstrated robust psychometric validity2 of the SWEMWBS with children and young people affected by domestic abuse, and Study D showed robust psychometric validity of the WEMWBS with adult victims of domestic abuse. These are significant findings given the limited number of measures that have been evaluated for use with this population across practice and research contexts. Moreover, this represents an important step forward in the implementation of the DVA-COS, which we hope will help to unify outcome measurement in domestic abuse research and evaluation, as well as service monitoring. Recommendations We recommend that the SWEMWBS and WEMWBS be used to measure wellbeing in the context of evaluation studies (of any quantitative design) seeking to assess the impact of child-focused domestic abuse interventions. To enhance the acceptability of the measure to children and adults we suggest minor adaptations for use in the domestic abuse context. Finally, we recommend the development of guidelines for practitioners and researchers about how to use the tools in a ‘carefirst’ way and how to guard against the tools being used for screening or triaging, or rationing care, as well as guidance for commissioners on how to interpret and use evidence, generated by the completion of the SWEMWBS and WEMWBS, for the basis of decision making. This guidance needs to reflect the balance between the benefits of data-driven decision making and the risk of unduly narrowing the breadth of services or thwarting innovation in the sector. The OMI’s implementation (including the use of guidance) should be closely monitored and evaluated, to inform any associated refinements and to develop an in-depth understanding of the process and outcomes associated with embedding routine measurement in practice. Further work is also required to identify an alternative OMI or adapt the SWEMWBS for appropriate use with children under the age of.   11.

Immigrants held in United States detention centers experience a de facto denial of their right to access to counsel. The 38,000 immigrants detained each day are largely held in remote facilities, where they experience extremely poor—often abusive—conditions; the inability to contact counsel or prepare their cases; and a legal framework that is stacked against them. Many scholars have studied the overlapping challenges detained immigrants face in a hostile regime and have proposed solutions ranging from ending immigration prison to providing universal representation for all those detained to revising legal rationales for detention. These ideas are good ones. However, as we work towards such goals, tens of thousands remain detained with little recourse. As a partial way to bridge that gap, we argue for a transformative, collaborative model of access to justice that focuses on community empowerment and combines the work of organizers, attorneys, and law students in clinics.

 This article uniquely blends both theory and practical perspectives to advance a theory of abolition-minded provision of legal services in detention. First, we explore the legal right of access to counsel for detained immigrants, with an overview of Constitutional and international human rights models. We then examine the severe barriers to this counsel that immigration detention creates. We then use theories of abolition and legal pedagogy to explore an innovative and critical model for expanding justice in immigration detention. We propose primary goals of increasing access to counsel, empowering communities, and supporting organizing to work towards the end of immigration detention.

 This article was inspired by our experiences representing detained immigrants in a clinical setting, with law students, and in coalition with agencies and organizers working on the ground. Through examples, stories, and even photographs, we weave in insights from this ongoing collaborative project to advance a framework for bridging the immigration detention justice gap.

The United States once authorized only border-based mandatory detention. However, immigration detention is now like an enormous fortress that has grown two mandatory detention turrets: status-based mandatory detention and crime-based mandatory detention. Status-based mandatory detention sees its only doctrinal foundations in the detention of those physically standing at the border. Yet, it has grown to reach both physically and temporally beyond those stopped at the border. Status-based mandatory detention first grew to include those stopped within 100 miles of a land border and under fourteen days in the U.S., whom immigration enforcement agents placed in expedited removal. Then, status-based mandatory detention grew further to include those stopped anywhere in the U.S. and under two years in the U.S., whom immigration enforcement agents placed in expedited removal. Most recently, status-based mandatory detention has grown to include persons who entered the U.S. at any time and whom immigration enforcement agents never placed in expedited removal. 
This article documents each of the blocks that have been placed in the massively-growing turret of status-based mandatory detention, and analyzes the strength of each block to hold up the turret. The article argues that broad status-based detention is inconsistent with the intent of Congress in passing what traditionally has been border-based mandatory detention. Under principles of statutory interpretation, this excessively large status-based mandatory detention turret cannot hold up.

Criminal networks such as human trafficking rings are threats to the rule of law, democracy and public safety in our global society. Network science provides invaluable tools to identify key players and design interventions for Law Enforcement Agencies (LEAs), e.g., to dismantle their organisation. However, poor data quality and the robustness of criminal networks make effective intervention extremely challenging. Although there exists a large body of work building and applying network scientific tools to green intervene criminal networks, these work often neglect the problems of data incompleteness and inaccuracy. Moreover, there is thus far no comprehensive understanding of the impacts of data quality on the downstream effectiveness of interventions. This work investigates the relationship between data quality and intervention effectiveness based on classical graph theoretic and machine learning-based targeting approaches. Decentralization emerges as a major factor in network robustness, particularly under conditions of incomplete data, which renders intervention strategies largely ineffective. Moreover, the robustness of centralized networks can be boosted using simple heuristics, making targeted intervention more infeasible. Consequently, we advocate for a more cautious application of network science in disrupting criminal networks, the continuous development of an interoperable intelligence ecosystem, and the creation of novel network inference techniques to address data quality challenges.
