A new report from Policy Exchange demonstrates how London is in the grip of a street crime epidemic and makes seventeen recommendations to show how the Metropolitan Police, City Hall and the Government can turn the tide.  

The report shows that:

• Knife crime in London increased by 58.5% in only three years between 2021 and 2024;

• Only 1 in 20 robberies and 1 in 170 “theft person” crimes in the capital were solved last year.

• 60% of the knife crimes committed in the capital were robberies – with over 81,000 mobile phones stolen in robberies and thefts last year.

• In 2024 one small geographic area of around 20 streets in London’s West End near Oxford Circus and Regent Street had more knife crime than nearly 15% of the rest capital combined; in 2023 these streets had more knife crime than 23% of the capital combined.

 The report identifies the top 20 neighbourhoods (technically known as Lower Layer Super Output Areas or LSOAs of about 15-20 streets each) in London which had the highest levels of knife crime in 2024. One in 15 of every knife crime offence in the capital in 2024 occurred in one of these 20 neighbourhoods (908 knife crimes). In 2024 only 4% of neighbourhoods accounted for nearly a quarter of all knife crime offences in the capital (3,615 knife crimes) and 15% of neighbourhoods accounted for half of all knife crime offences (7055 knife crimes).

The report identifies that within the Metropolitan Police there are least 850 police officers currently in non-frontline posts which could be redeployed to the policing frontline to tackle knife crime, robbery and theft in the areas where criminals are most prolific. This includes police officers currently posted to the following departments: Transformation (142 officers), Human Resources (24 officers), Culture, Diversity and Inclusion (20 officers) and Digital, Data & Technology (34 officers).  

Policy Exchange rejects the suggestion that stop and search is being deployed in a “racist” way. While only 39.5% of those stopped and searched by the police are black, 43.6% of those charged with murder are black, 45.6% of non-domestic knife-crime murder victims are black and 48.6% of robbery suspects are black. 13.5% of London’s population are black. Policy Exchange asserts that it is not “racist” when the police are merely responding to the demographic breakdown of serious and violent offending in the capital.  

Policy Exchange analysis shows that the courts are taking a dangerously lax approach to the most prolific criminals. Despite already having 46 or more previous convictions, “Hyper-Prolific Offenders” are sent to prison on less than half of all occasions (44.5%) on conviction for a further indictable or either-way offence – 4,555 such criminals walked free from court in 2024. For “Super-Prolific Offenders” (those with 26 to 45 previous offences) this falls to 42.1% with 9,483 such criminals walking free from court in 2024. Despite there being mandatory sentencing provisions for repeat knife-carriers to be sent to prison over a third are not sentenced to a term of immediate custody

Crest Advisory was commissioned by the Accelerated Capability Environment (ACE) on behalf of the Office of the Police Chief Scientific Adviser (OPCSA) to conduct research examining the social and psychological impacts of deepfakes on victims, with a focus on violence against women and girls (VAWG). This rapid evidence review compiles relevant literature which informed our lines of enquiry and refined the scope of our primary research and engagement, including a public attitudes survey. This document has been iterated throughout the commission to ensure it is up to date at the time of writing (July 2025) and captures relevant emerging literature. Deepfakes refer to any audio, image or video which has been digitally altered using machine learning methods. This includes fraudulent, political, or humorous content, as well as intimate images and pornography. However, in line with the focus of this commission, our evidence review focuses on deepfake violence against women and girls (VAWG). This focus reflects evidence that the vast majority of deepfake videos are sexualised in nature, with women being the disproportionate target of this abuse.

Zambia is a significant source of critical minerals including copper, cobalt, lithium, nickel and graphite. Interest in Zambia’s minerals is growing, particularly from Western countries and China. Unfortunately, due to governance weaknesses, there is ample corruption and illicit financial flows at several transaction levels in the value chain. This U4 Issue therefore identifies government interventions Zambia can use to curtail corruption considering existing political pressures.

Main points

• Intense competition for critical mineral value chains results in an increased risk of revenue leakage due to corruption and tax evasion. Illicit financial flows (IFF) threaten Zambia’s economic development and undermine its fiscal systems.

• Zambia has formal commitments in place, such as laws, regulatory institutions and international commitments, to battle corruption and IFFs, but the institutional architecture is fragmented and inadequately enforced. Inter-agency collaboration is required to address these challenges.

• Through a literature review, including a law and policy review, and a stakeholder mapping exercise with 21 key informant interviews with government, civil society, academic and industry representatives, we constructed a qualitative understanding of the key risk factors for corruption and IFFs.

• Significant factors are the lack of a transparent, coherent and disciplined mining licensing system; a non-transparent bidding process; public-private collusion across value chains; abuse of intermediaries and agents; and weak regulation in the sector.

• Opportunities for interventions are enhanced systems for disclosure and due diligence, reform of the Mining Cadastre, support for evidence-based policymaking, support for the organisation of the artisanal mining sector, enhanced quality of civil society organisation public discourse, and enhanced collaboration in anti-corruption agencies, while keeping political pressures in mind.

Courts in several jurisdictions have recognised corruption as a direct human rights violation, enabling broader legal standing, integrating international law and focusing on victims. Case studies, predominantly from Latin America, illustrate different legal theories used to hold officials accountable and expand access to justice in anti-corruption proceedings. Consequently, the formulation of a stand-alone right has merit despite limitations.

Tobacco smuggling remains a widespread illegal activity in Canada, associated with important social and economic impacts, and often linked to organized crime. This study explores the application of forensic profiling as an intelligence tool to support the analysis of contraband cigarette production and distribution. Physical and chemical manufacturing characteristics of seized contraband cigarette packs, provided by the Canada Border Services Agency (CBSA), were observed and coded using macroscopic, microscopic, and spectroscopic techniques. Multivariate statistical analyses were then conducted to compare manufacturing characteristics between packs and identify potential links. The analyses highlighted links between cigarette packs and seizures based on shared manufacturing characteristics. The results and the identified groups were also compared with seizure data provided by the CBSA. The results demonstrate the relevance of forensic profiling to formulate hypotheses regarding shared production processes or supply networks. These hypotheses provide information that contributes to understanding tobacco smuggling and aim to examine how forensic intelligence can support law enforcement and measures to prevent and disrupt this criminal activity. A preliminary optimal procedure for applying forensic profiling in operational contexts targeting contraband tobacco was finally proposed. Despite limitations in the dataset creation that were beyond our control, this study represents a starting point for applying this scientific approach to tobacco smuggling

The chapter reviews the economic literature on intimate partner violence (IPV), a widespread human rights violation affecting nearly one in three women globally and generating significant societal costs. It focuses on the relationship between various dimensions of female empowerment and IPV. The chapter begins by outlining key theoretical frameworks—including household bargaining, instrumental violence, male backlash, and exposure theories—as well as the main data sources used to study IPV. It then reviews empirical evidence on how factors shaping female empowerment at the individual, relationship, community, and societal levels influence IPV outcomes. Central themes include labor market dynamics, education, income shocks, family formation, legal frameworks, institutional access, and gender norms. The chapter also considers how these factors interact across levels and discusses additional drivers of IPV not directly linked to female empowerment. The goal is to provide an overview of causal evidence from the economic literature on IPV while emphasizing its complexity and the importance of a context-specific, intersectional approach to both its analysis and prevention.

We examine the impact of a 2002 Danish parental leave reform on intimate partner violence (IPV) using administrative data on assault-related hospital contacts. Using a regression discontinuity design, we show that extending fully paid leave increased mothers’ leave-taking and substantially reduced IPV, with effects concentrated among less-educated women. The reform also lengthened birth spacing, while separations remained unchanged and earnings effects were modest. The timing and heterogeneity of impacts point to fertility adjustments—rather than exit options or financial relief—as the key mechanism. Parental leave policy thus emerges as an underexplored lever for reducing IPV.

The text discusses, in an exploratory way, how the environmental issue related to the Brazilian Amazon attracts international attention and potentially serves as a mechanism of external constraint in Brazil’s internal affairs. Complaints of environmental crimes and crimes against indigenous peoples are debated in the international political environment, without considering Brazilian sovereignty on these and other topics. In some cases, such debates are used, as pretexts, to halt negotiations of trade agreements beneficial to the country. In summary, the text explores the concept of national sovereignty in the face of global pressures and the impacts of international agendas on Brazilian government action, pointing out that there are complexities and nuances of this geopolitical interaction, in addition to the common good of environmental preservation or the protection of indigenous peoples.

School exclusion—commonly referred to as suspension—is a disciplinary response employed by school authorities to address student misbehaviour. Typically, it involves temporary removal from regular teaching or, in more serious cases, complete removal from the school premises. A substantial body of research has associated exclusion with adverse developmental outcomes. In response, various school-based interventions have been developed to reduce exclusion rates. While some programmes have shown promising effects, the evidence on their effectiveness remains inconclusive. This mixed-methods systematic review and multi-level meta-analysis updates the previous review by Valdebenito et al. (2018), which included literature published between 1980 and 2015. The present update extends the evidence base by including studies until 2022. The primary aim of this review was to assess the effectiveness of school-based interventions in reducing disciplinary exclusions, with secondary aims focused on related behavioural outcomes including conduct problems, delinquency, and substance use. Systematic searches conducted between November and December 2022 yielded over 11,000 references for quantitative studies. Following title and abstract screening, 777 records were reviewed at full text by two independent coders. Thirty-two studies met the inclusion criteria for meta-analysis, comprising 2765 effect sizes from 67 primary evaluations (1980–2022) and representing approximately 394,242 students. Meta-analysis was conducted using a multilevel random-effects model with robust variance estimation to account for the nested structure of the data. Quantitative impact evaluations were eligible if they used a randomised controlled or quasi-experimental design, included both a control group and pre/post-test data, and used statistical methods to minimise selection bias (e.g., propensity score matching or matched cohort design). Studies were excluded if they exhibited substantial baseline differences between treatment and control groups. The qualitative synthesis explored implementation barriers and facilitators based on nine UK-based process evaluations, identified through searches completed in September 2023. Process evaluations were included if they focused on the perceptions of stakeholders—teachers, students, or school leadership—within UK schools. Data collection followed two stages: initial selection based on titles, abstracts, and keywords, followed by full-text review. Two independent coders applied inclusion criteria, extracted data, and resolved discrepancies with the principal investigators. All steps were documented to inform the PRISMA flow chart. To evaluate interventions reducing school exclusions, we conducted a multilevel meta-analysis using robust variance estimation. We explored heterogeneity via meta-regression (e.g., gender, intervention type), conducted sensitivity analyses for outliers and correlation structures, and assessed quality data using the EPOC, ROBIN-I and CASP checklist for methodological quality. Findings indicated that school-based interventions were associated with a small but statistically significant reduction in school exclusion (standardised mean difference [SMD] = 0.104; 95% CI: 0.04 to 0.17; p < 0.001). Compared with the original 2018 review, which reported a slightly larger effect size, this update benefits from a broader evidence base and more advanced statistical modelling. However, the results for secondary behavioural outcomes were more limited: effects on conduct problems and delinquency were negligible or non-significant, and the impact on substance use was small and not statistically significant. Risk of bias was assessed using the Cochrane EPOC 2 tool (Higgins and Green 2011) for randomised controlled trials and ROBINS-I (Sterne et al. 2016) for quasi-experimental designs. Randomised studies generally exhibited lower risk of bias, while quasi-experimental studies showed greater variability in quality. Four major themes emerged from the analysis. First, intervention format mattered: flexible, collaborative, and well-structured interventions facilitated implementation, while outdated materials or content misaligned with local context impeded delivery. Second, consistency in school policies and practice enabled smoother implementation, whereas inconsistency acted as a barrier. Third, staff buy-in—particularly among senior leaders—was essential for successful implementation, although resistance from more experienced staff was noted. Finally, perceived effectiveness played a motivational role: visible improvements in pupil behaviour supported continued engagement with the intervention. In summary, the updated review finds that school-based interventions can modestly but significantly reduce school exclusions. While more serious disciplinary sanctions such as permanent exclusions and out-of-school suspensions appear less responsive, in-school exclusion shows greater potential for reduction. Impacts on other behavioural outcomes remain limited. These findings suggest that targeted, context-sensitive interventions supported by strong implementation strategies and whole-school engagement are most likely to achieve sustained reductions in school exclusion.

Although much is known about recidivism risk, less is known about factors predicting early release. The current study analyses a sample of 2,070 adult felony probation clients to see if offense characteristics, domains from the Texas Risk Assessment System (TRAS), and demographic variables impact both revocation and successful early release. Results revealed that predictors of early release mirrored those of revocation with one exception—race. Specifically, Black clients were 27% less likely to be granted early release. The findings highlight the TRAS is an effective tool to help mitigate bias for revocation of probation but not for granting early release.

This CEIAS paper aims to shed light on cooperation between Chinese businesses and Mexican criminal groups. It specifically analyzes cases related to drug trafficking and the exploitation of natural resources in three states in Mexico. The topic is particularly relevant for countries in Latin America that have been expanding their commercial ties with China. This research suggests that the lack of state supervision in some of these countries could allow alternative structures—such as criminal groups and Chinese organized networks—to thrive and fill the security and economic void if not regulated properly.

Summary

Mexico’s macroeconomic stability and abundant natural resources have made the country into an attractive destination for Chinese businesses.

The country still suffers from a lack of internal security, most of it stemming from the Mexican Drug War, an ongoing multilateral low-intensity conflict between the Mexican government and a large number of criminal organizations.

In some of Mexico’s states, pervasive violence and instability have resulted in a power vacuum. With the government being unable to guarantee security, non-state actors such as criminal organizations and/or civilian militias seize the opportunity to establish their own rule.

When foreign companies operate in such troubled areas, they inevitably run into problems caused by Mexico’s security issues.

Within this trend of foreign companies operating in Mexico, some level of tacit cooperation has been observed between Chinese businesses and non-state actors. This cooperation is often an outcome of localized security vacuums that are exploited by alternative security providers, such as criminal organizations, that can fill them and provide operational safety for local businesses.

A growing body of research has identified the existence of Chinese illicit networks and their involvement in the trafficking of people, narcotics, and contraband goods, as well as money laundering and illegal arms trade in Mexico.

Concealed under the guise of legal commercial activity, networks of Mexican criminal organizations and their Chinese business partners exploit the dire security situation in some areas of Mexico.

Despite attempts by the Chinese and the Mexican governments to regulate certain sectors that contribute to the existence of the illicit networks in Mexico, there are still substantial opportunities that are ripe for exploitation by the criminal group-legitimate business partnerships

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.

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.

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.

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 

 policy within institutional constraints.

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.

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.

This study examines the relationship between the incidence of willful homicides committed with firearms and economic factors in the subprefectures of São Paulo (Brazil) in the year 2023. The analysis involved comparing records of willful homicides with the average family income in the locations where the crimes occurred. The results indicate a lack of significant statistical correlation between the incidence of such crimes and the economic conditions of the analyzed regions. Therefore, one possible conclusion is that family income alone is not a determinant factor in the observed crime patterns. In summary, although the average family income provides valuable insights into the socioeconomic scenario of the subprefectures, it is insufficient to elucidate the complexity of urban crime in São Paulo. So, this study suggests that other factors, possibly related to social, cultural, or public policy dynamics, should be considered for a more comprehensive understanding of the homicide patterns in the city.

Police disciplinary proceedings are brought in cases where it is agreed, following an investigation, that a police officer has a case to answer for: • misconduct (meaning a breach of the standards of professional behaviour that justifies disciplinary action of at least written), or • gross misconduct (meaning a breach of the standards of professional behaviour that is so serious to justify dismissal) A decision on whether there is a case to answer is based on whether there is sufficient evidence upon which a misconduct panel “could make a finding on the balance of probabilities” that an officer’s behaviour amounted to misconduct or gross misconduct. The Commons Library briefings Police standards: Complaints and Police Standards: Conduct explain in more detail how allegations of police wrongdoing are investigated.
