Focusing on the lived experiences of Afro-Colombians processing and resisting violence against their ecological communities, Visions of Global Environmental Justice employs accounts of the supernatural narratively and analytically to frame a contemporary struggle for environmental justice. The book applies Achille Mbembe’s theorization of necropolitics to the environmental racism of the US War on Drugs in Colombia, specifically the aerial eradication of coca in the comunidades negras of the Pacific Coast. Through critical examination and deconstruction of transnational mythmaking and local oral tradition, Visions of Global Environmental Justice illustrates that non/humans rendered expendable by US-driven drug (necro)politics are indispensable to both the conceptualization and the realization of environmental justice globally. Far from being a study singularly focused on the symptoms of environmental issues, this book creatively guides us toward a broader understanding of environmental racism and justice across geographic scales and non/human agencies.

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

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

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

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

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

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

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

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

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

Online disclosure of sexual violence victimisation is a relatively new phenomenon. While prior research has mainly relied on analysis of Twitter data from the #MeToo period, this study compares such disclosures across platforms over two years. Using machine learning, 2927 disclosures were identified for quantitative content analysis and multiple correspondence analysis. Online platforms differed in timing of the posts, information shared, information density, co-occurrence of information and the length of the disclosure message. Most disclosures were found on the platform Twitter, and during the #MeToo movement. These posts differ from disclosures on other platforms and outside the viral movement. Regarding the content, across all platforms and periods, clustering was found around offender-oriented information, making the offender an explicit part of the experience. This study shows that an exclusive focus on online disclosures on Twitter and during viral movements gives a biased and incomplete picture of what online disclosure of sexual victimisation entails. Our cross-platform analysis over time allows for more universal statements about the content and context of online disclosures of sexual victimisation.

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

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

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

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

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.

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.
