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

As gatekeepers to restorative justice (RJ) programs for domestic and family violence (DFV) and sexual violence, stakeholders in referring agencies perform the critical role of assessing the suitability of cases for entry into these programs. This article draws on interviews with 47 stakeholders in an RJ program for DFV and sexual violence in the Australian Capital Territory to better understand stakeholder decision-making about referrals. Findings show stakeholders’ decisions around which matters to refer to RJ centre on assessments of victim‑survivors’ safety and offender accountability. Many stakeholders are risk averse when deciding whether to make a referral, which may inadvertently reduce opportunities for victim-survivors to benefit and achieve their justice goals.

We live in an age of insecurity. The Global Financial Crisis, the Covid-19 pandemic, the wars in Ukraine and Gaza and the climate crisis are just the most evident examples of shocks that have increased the level of insecurity among elites and citizens in recent years. And yet there is ample evidence that insecurity is not equally distributed across populations. Bringing together disciplines such as political science, criminology, sociology, and anthropology and combining quantitative and qualitative studies from a wide range of rich and middle-income countries, this collection presents a new framework for exploring the two key social challenges of our times – insecurity and inequality – together. The volume analyses the nature, causes and distribution of subjective insecurities and how various actors use or respond to unequal security. The essays cover a host of themes including the unequal spatial distribution of (in)security, unequal access to security provision in relation to crime and welfare, the impact of insecurity on political attitudes as well as policy responses and the political exploitation of insecurity. An important contribution to debates across several social scientific disciplines as well as current public debate on insecurity and politics, the volume will be of great interest to scholars and researchers of criminology, social policy, peace and conflict studies, politics and international relations, sociology, development studies and economics. It will also be of interest to policymakers and government think tanks.

This book presents a synthesis of selected trends in the dynamics and structure of crime in Poland over the past 30 years, in the context of ongoing social transformations in the wider region. The book explores the impact of the deep systemic transformation of the late 1980s and early 1990s on the phenomenon of crime, its structure and dynamics, and the policy of its control in the following decades. It also examines the impact of changes resulting from the dynamic development of Polish society in the 21st century in the context of global changes towards the emergence of a new form of collective life, a mobile information society based on modern technologies. The focus is primarily on those deviant behaviours that can most obviously be linked to social changes, primarily political, economic, legal, and technological. The work examines disclosed crime figures available in official statistics. It also looks to the future considering the global societal changes caused by the outbreak of the COVID-19 pandemic. Based on preliminary observations made in selected countries, the authors describe associated changes in criminal behaviour and identify some pivotal developments that may influence future trends. The book will be of interest to academics and researchers working in the areas of criminal law, criminology, sociology and criminal policy.

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.

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

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

What are controlled drugs? Controlled drugs are substances that are considered harmful to human health and subject to legal controls. In the UK, these drugs are categorised as Class A, Class B or Class C according to their potential harm. Class A drugs like heroin and cocaine are considered the most harmful. They are subject to the strictest legal controls and penalties for misuse. Controlled drugs legislation The Misuse of Drugs Act 1971 regulates the production, supply and possession of controlled drugs in the UK. The act is complemented by the Misuse of Drugs Regulations 2001, which set out exceptions that allow the lawful possession and use of certain controlled drugs for medical, dental and veterinary use. The regulations categorise drugs into five schedules, according to their medical usefulness and the potential harms of misuse. Schedule 1 drugs are considered to have no legitimate current medical use and are the most tightly controlled. Classification and scheduling decisions The Advisory Council on the Misuse of Drugs (ACMD) is an independent expert advisory body that advises the government on the classification and scheduling of drugs. The Home Secretary can make changes to the classification of a drug after consultation with the ACMD. However, the government is not required to take their advice. The Library Insight Nitrous Oxide becomes a Class C drug describes how nitrous oxide was classified as a Class C substance, despite ACMD advice that it should become a controlled drug. Drug offences and enforcement It is an offence to import, produce, supply or possess a controlled drug, except in circumstances specified in law. The maximum sentences available are specified in schedule 4 of the Misuse of Drugs Act 1971. In England and Wales, sentencing guidelines set out the appropriate sentence for convicted offenders. The drugs market is dominated by serious and organised crime groups, with several UK enforcement agencies involved in seeking to tackle the production, supply and importation of drugs. The National Crime Agency and Regional Organised Crime Units work with regional police forces and the British Transport Police, to tackle drug supply operating across police force boundaries, including county lines. The National Crime Agency also leads on cooperation with international agencies oversees to tackle international supply lines. Border Force is the lead agency for seeking to intercept drug shipments from crossing UK borders. Responding to drug possession The possession of any controlled drug is an offence under section 5 of the Misuse of Drugs Act 1971, carrying a penalty of up to 7 years’ imprisonment. However, in many cases people found in possession of small quantities of drugs for personal use will not be prosecuted. The police have a large degree of discretion when deciding to arrest and prosecute an individual for drug possession or whether instead to issue an out of court resolution. In some areas of England and Wales, drug diversion programmes are being trialled to refer people into drug treatment services as an alternative to criminal justice sanctions entirely. There has also been debate about whether the government should go further in embracing a health-led approach to people who use drugs. For example, the Home Affairs Committee in 2023 called for responsibility for misuse of drugs to be jointly owned by the Home Office and Department of Health and Social Care, and for a wider use of drug diversion schemes and harm reduction measures. Changes to controlled drugs legislation There have been multiple calls for reform of controlled drugs legislation in the UK, including calls to change how drugs are classified and scheduled under the legislation. In December 2024, the Controlled Drugs (Procedure for Specification) Bill, a Private Member’s Bill sponsored by Alex McIntyre MP, is due to have its second reading in the House of Commons. This bill proposes changes to the processes used to change drug classifications. It aims to allow the government to make changes more quickly and allow corresponding changes to the classification of drugs (under the Misuse of Drugs Act) and scheduling of drugs (under the Misuse of Drugs Regulations) to be made at the same time.

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.

Observational evidence suggests that better ambient lighting leads people to feel safer when spending time outdoors in their community. We subject this finding to greater scrutiny and elaborate on the extent to which improvements in street lighting affect routine activities during nighttime hours. We report evidence from a survey experiment that examines individual's' perceptions of safety under two different intensities of nighttime ambient lighting. Brighter street lighting leads individuals to feel safer and over half of survey respondents are willing to pay an additional $400 per year in taxes in order to finance a hypothetical program which would replace dim yellow street lights with brighter LED lights. However, poor lighting does not change people’s willingness to spend time outdoors or to engage in behaviors which mitigate risk. Results suggest that street lighting is a means through which policymakers can both control crime and improve community well-being.

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.

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

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

While Black males are disproportionately impacted by gun homicide, they are also grossly impacted by non -fatal shootings. The impact of gun violence extends far beyond the immediate physical harm inflicted by bullets; this harm can permeate and disrupt personal relationships, create lasting psychological distress, and undermine a sense of safety within communities. However, the needs of injured Black men are often overlooked in public discourse. Despitethe prevalenceofthesetraumaticexperiencesinthe livesoflow-incomeBlackmen,theirresponseto trauma is often treated as pathology, with fewer resources devoted to addressing the adverse consequences associated with these experiences. This policy brief summarizes key findings from a study involving 18 in-person semi-structured interviews with Black men across the United States who have sustained a gunshot injury. The findings highlight the individual and institutional harm Black men with gunshot wounds (GSWs) experience at the hands of both police officers and health care providers. Consequently, this brief proposes changes designed to positively impact the lives of Black men affected by gun violence throughout the continuum of care.

Shocking videos surfaced in late August of gun-wielding Venezuelan migrants storming an apartment building in the suburban city of Aurora, Colorado. One of the migrants, a 20-year-old, confessed that he is part of a Venezuelan gang called Tren de Aragua (TdA, or “Train from Aragua”). The Aurora police department is now beefing up its budget to confront the increased crime spilling over from the sanctuary city next door in Denver.Aurora was just the beginning. In the past 11 months, there have been increasing reports of TdA activity in no fewer than 30 major cities across America. At least 100 federal investigations involving the TdA are underway, catching most of the U.S. law enforcement community by surprise. Shooting two New York City

police officers, building sex trafficking rings in Louisiana, and murdering the Georgia nursing student Laken Riley and 12-year-old Jocelyn Nungaray in Houston are just some of the high- profile violent crimes carried out by the TdA. Moreover, given that the Venezuelan government does not cooperate or provide any data on suspected criminals coming from their country into the United States, some law enforcement officers have dubbed the TdA as “ghost criminals” with little to identify them other than confessions and/ or tattoos. The Tren de Aragua has been around for more than a decade, first as a Venezuelan prison gang, then as a transnational criminal organization (TCO) spreading throughout Latin America, and now as a major street gang terrorizing cities in at least 20 states throughout America—and growing. Many comparisons have been drawn between the TdA and the transnational Salvadoran gang, La Mara Salvatrucha 13 (MS-13). The TdA, however, is expanding much more quickly, likely due to its unique origin and state sponsorship in Venezuela. Unlike MS-13, which was born in Los Angeles in the 1980s, the TdA is foreign-born and was virtually nonexistent in America until 2021, distinct from other major TCOs such as MS-13 or the Mexican cartels. The TdA’s rapid expansion in the United States is a direct consequence of the Biden–Harris Administration’s failed immigration policies and lack of border enforcement.

KEY TAKEAWAYS The TdA’s goal is to establish territorial control and impose a criminal economy that connects illicit networks to penitentiaries in or near those neighborhoods. The new Trump Administration should work with Latin American partners to dismantle the TdA throughout the Western Hemisphere.

ntroduction

Substance use is a growing public health concern in West Africa, contributing to significant morbidity, mortality, and socioeconomic challenges. Despite the increasing prevalence, comprehensive data on the patterns and factors influencing substance use in the region remain limited. This systematic review and meta-analysis aim to synthesize existing research on the prevalence and patterns of substance use in West Africa, providing critical insights for developing targeted interventions and policies.

Methodology

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses [PRISMA] guidelines. A systematic search was performed across four major databases [PubMed, Web of Science, CINAHL, and Scopus] from January 2000 to June 2024. A total of 22 studies involving 43,145 participants met the inclusion criteria. Multiple reviewers performed data extraction and quality assessment independently, and a random-effects meta-analysis was used to estimate the pooled prevalence of various substances. Sensitivity analysis was conducted using a leave-one-out approach to evaluate the influence of individual studies on the overall prevalence.

Results

The meta-analysis revealed the pooled prevalence rates of alcohol [44%], cannabis [6%], tramadol [30%], codeine [11%], and kolanut [39%]. The analysis identified high heterogeneity across studies [I2 = 98– 99%], reflecting diverse substance use patterns and influencing factors, including peer influence, availability of substances, socioeconomic conditions, and demographic characteristics. Sensitivity analysis indicated that no single study significantly impacted the overall prevalence estimates, confirming the robustness of the findings.

Conclusion

Substance use in West Africa is widespread and influenced by complex factors. The high prevalence of alcohol and tramadol use highlights the urgent need for targeted public health interventions, including stricter regulatory frameworks, community-based prevention programs, and comprehensive public education campaigns. This study provides a critical foundation for developing effective strategies to mitigate the escalating substance use crisis in the region.

Summary Due to their difficult political paths – Ethiopia’s stalled transition and Tunisia’s reversal – these two nations demonstrate the effects of failing transitions and democratic backsliding on rising transnational organised crime. Reversing the current trend of organised crime depends heavily on restoring stability and rule-of-law-based democracies, which could be achieved through a revived political process that embraces dialogue and transitional justice to mitigate the challenges and enable governance structures to tackle the complexities of organised crime. Key points The surge in transnational organised crime in Ethiopia and Tunisia can be seen as a consequence of their unrealised political transitions due to: • ensuing economic upheaval that has been the major driver of transnational organised crimes in both countries • porous borders and ungoverned spaces that allow criminal networks to grow • attention to pressing security challenges, such as conflicts and terrorism, that create space for criminal networks to strengthen and operate with impunity

Drug overdoses are one of the leading causes of injury death in adults and have risen over the past several decades in the United States (1–3). Overdoses involving synthetic opioids (fentanyl, for example) and stimulants (cocaine and methamphetamine, for example) have also risen in the past few years (1). This report presents rates of drug overdose deaths from the National Vital Statistics System over a 20-year period by demographic group and by the type of drugs involved, specifically, opioids and stimulants, with a focus on changes from 2022 to 2023. Key findings Data from the National Vital Statistics System ● The age-adjusted rate of drug overdose deaths increased from 8.9deaths per 100,000 standard population in 2003 to 32.6 in 2022; however, the rate decreased to 31.3 in 2023. ● Rates decreased between 2022 and 2023 for people ages 15–54 and increased for adults age 55 and older. ● From 2022 to 2023, rates decreased for White non-Hispanic people, while rates for other race and Hispanic-origin groups generally stayed the same or increased. ● Between 2022 and 2023, rates declined for deaths involving synthetic opioids other than methadone, heroin, and natural and semisynthetic opioids, while the rate for methadone remained the same. ● From 2022 to 2023, rates increased for deaths involving cocaine by 4.9% (from 8.2 to 8.6) and psychostimulants with abuse potential by 1.9% (10.4 to 10.6)

Synthetic illicit drugs, such as nitazenes and fentanyls, are becoming commonplace in countries around the world, including in Europe, Australia, and Latin America, which raises concern for overdose crises like those seen in North America. An important dimension of the risk represented by synthetic drugs is the fact that they are increasingly packaged in counterfeit pill form. These pills—often indistinguishable from authentic pharmaceuticals—have substantially widened the scope of populations susceptible to synthetic drug overdose in North America (eg, among adolescents experimenting with pills or tourists from the USA seeking psychoactive medications from pharmacies in Mexico). The non-medical use of diverted prescription medications is relatively more common, and less stigmatised, than the use of powder drugs. Many consumers of counterfeit pills are unaware that they contain synthetic illicit drugs, believe them to be authentic pharmaceuticals, and would be unlikely to consume those drugs knowingly or if in powder form. Given these issues, we recommend the expansion of educational and awareness campaigns, pill testing programmes to help consumers shift demand to safer products, increased monitoring in routine clinical scenarios and overdose death toxicology, and expanding medically managed safer alternatives to counterfeit pill use.\

A mob destroyed 35-square-blocks of the African Amer i can Community during the eve - ning of May 31, through the afternoon of June 1, 1921. It was a tragic, infamous moment in Oklahoma and the nation’s history. The worst civil disturbance since the Civil War. In the aftermath of the death and destruction the people of our state suffered from a fatigue of faith — some still search for a statute of limitation on morality, attempting to forget the longevity of the residue of injustice that at best can leave little room for the healing of the heart. Perhaps this report, and subsequent humanitarian recovery events by the governments and the good people of the state will extract us from the guilt and confirm the commandment of a good and just God — leaving the deadly deeds of 1921 buried in the call for redemption, historical correctness, and re pair. Then we can proudly sing together: “We know we belong to this land. “And the land we belong to is grand, and when we say, ay yippy yi ki yea, “We’re only saying, you’re doing fine Oklahoma.” “Oklahoma, you’re O-K-L-A-H-O-M-A, Oklahoma OK.”

To be successful, cybercriminals must figure out how to scale their scams. They duplicate content on new websites, often staying one step ahead of defenders that shut down past schemes. For some scams, such as phishing and counterfeit goods shops, the duplicated content remains nearly identical. In others, such as advanced-fee fraud and online Ponzi schemes, the criminal must alter content so that it appears different in order to evade detection by victims and law enforcement. Nevertheless, similarities often remain, in terms of the website structure or content, since making truly unique copies does not scale well. In this paper, we present a novel optimized combined clustering method that links together replicated scam websites, even when the criminal has taken steps to hide connections. We present automated methods to extract key website features, including rendered text, HTML structure, file structure, and screenshots. We describe a process to automatically identify the best combination of such attributes to most accurately cluster similar websites together. To demonstrate the method’s applicability to cybercrime, we evaluate its performance against two collected datasets of scam websites: fake escrow services and high-yield investment programs (HYIPs). We show that our method more accurately groups similar websites together than those existing general-purpose consensus clustering methods.

• Smugglers were the top source of information for those who obtained information prior to starting their journey (50%), even more so for women (60%).This high percentage likely stems from the unique sampling criteria, in which all respondents used a smuggler. • However, 28% of migrants overall considered smugglers to be the most reliable source of information, and less so among women (21%).
