  Background Supervised consumption services (SCS) are effective at preventing overdose mortality. However, their effect on public safety remains contested. We investigated homicide rates in areas near SCS in Toronto. Methods We classified coroner-reported fatal shootings and stabbings (January 1st, 2010 to September 30th 2023) by geographic zone: within 500 m (‘near’), between 500 m and 3 km (‘far’), and beyond 3 km of an SCS (‘out’). We then used Poisson regression to calculate the rate ratio (RR) across zones 18, 36, 48, and 60 months pre vs. post SCS implementation. Finally, we compared spatial homicide incidence prior to and after the date of the implementation of each SCS using interrupted time series (ITS). Findings Overall, 956 homicides occurred, and 590 (62%) were fatal shootings and stabbings. There was no meaningful change in the rate of fatal shootings and stabbings within 3 kms of SCS (near and far zones) after their implementation. However, between 48 and 60 months pos-implementation, we detected an increase in out zones. In an ITS analysis, we observed a reduction in the monthly incidence in near zones and an increase in out zones. Interpretation SCS implementation was not associated with increased homicide rates; instead, we observed a reduction in monthly incidence near SCS. These results may inform drug market activity responses that optimize community health and safety.

Three Key Questions ♦ How are the activities of law enforcement agencies impacted by climate change and what are the implications of this for future practice? ♦ What capacities and organisational attributes are required by law enforcement agencies in responding to the challenges posed by climate change and environmental degradation? ♦ What improvements can be made to law enforcement responses to the challenges posed by climate change and environmental degradation? Legal and Professional Contexts ♦ Crimes that affect the environment are increasingly being prioritised by the United Nations and other international bodies, as well as regional and domestic authorities. ♦ A paradigm shift is occurring due to changing circumstances that is reshaping contemporary responses to the law enforcement mission and mandate. This has ramifications for how law enforcement work is carried out, the resources needed to do so, and the collaborations required across agencies and between community and government. Crimes that Affect the Environment and Climate Change ♦ Crimes that Affect the Environment Contributing to Climate Change Deforestation – diminishment of carbon sinks, adding to carbon emissions; Illegal mining – air pollution; polluting freshwater systems, Wildlife trafficking – loss of certain species and individuals may undermine the functioning of ecosystems exacerbating conditions leading to climate change; Land grabs and changing land uses – lost carbon stock and sequestration, adding to carbon emissions. ♦ Climate Change Affecting Existing Categories of Crime Water crimes – resource scarcity and water theft; Clandestine migration – climate refugees; Illegal mining – rare earth minerals for new renewable energy systems; Social conflict – aggression and violence over scarce resources, social strains arising from biophysical changes, changes in routine activities depending on weather. ♦ Cross-Over Crimes Associated with Crimes that Affect the Environment and Climate Change Homicide – killing of park rangers, environmental activists, local residents; Organised crime groups and networks – fraudulent green investments, low-price food on-sales; Corruption – direct (criminal such as document fraud) and moral (unethical policies and practices that foster carbon emission pollution); Disaster-related fraud – building practices, insurance claims, victim scams and identity theft. Climate Change Risks and Disasters ♦ The planet is heating up at an unprecedented rate and this is accelerating. The effects of this are manifest in high impact and extreme weather events and increases in all manner of risks and harms. This is global in nature. ♦ The notion of harmscape captures the idea of intersecting and interacting harms. Climate change impacts and risks are becoming increasingly complex and more difficult to manage. ♦ The intersectional dimensions of responding to climate disruption include three main features: climate related crimes (e.g., water theft); climate-related events (e.g., wildfires); and climate-related problems (e.g., prolonged homelessness), all of which are interconnected. Capacities and Capabilities of Law Enforcement Agencies ♦ While there may be rising interest and need for greater law enforcement intervention arising from climate-related events and trends, at present there is generally insufficient capacity to meet the challenges of either crime fighting or disaster and emergency management. ♦ A change in and pluralisation of police roles is occurring, in which greater attention is being devoted to matters such as climate change mitigation, reduction of climate-related crime or first responder work on the frontline of environmental disasters. ♦ There are a multitude of stakeholders and agencies with which law enforcement must engage and collaborate with, with numerous tensions and opportunities evident at the grassroots level with regard to state-community relations. A New Paradigm for Global Law Enforcement ♦ A robust response to climate-related crime and disaster events hinges to a large extent on the strength and resilience provided by the community and NGO sectors working in conjunction with state authorities. ♦ A wide range of equipment and technologies are required in the fight against climate-related crimes and in responding to disasters and emergencies. These need to be shared out at the global scale. ♦ Information management systems are crucial to both combating climate-related crimes as well as predicting and responding to climate-related disasters and their short- and long-term social and environmental consequences. ♦ It is vital that multi-agency and multi-disciplinary teams and forums be provided that bring together in a coordinated manner the knowledge, expertise and experience of a wide range of practitioners. ♦ A range of strategic actions are required for effective environment and climate-related global law enforcement. The emphasis must be on preparedness and rapid mobilisation of human and technical resources.

The National Strategy to Combat Human Trafficking (National Strategy) is a five-year (2019-2024) strategy aiming to strengthen Canada’s response to human trafficking. It follows from the National Action Plan to Combat Human Trafficking which expired in 2016. The National Strategy is a whole of government endeavour that aligns efforts with the internationally recognized pillars of prevention, protection, prosecution and partnership. Canada has added a fifth pillar, empowerment, to enhance support and services to victims and survivors of human trafficking. The activities under the pillars are the responsibility of many partner departments and agencies. Several partner departments and agencies received funding for activities specific to the National Strategy. These include, Public Safety Canada (PS), the Canada Border Services Agency (CBSA), the Financial Transactions and Reports Analysis Centre (FINTRAC), Women and Gender Equality (WAGE) Canada, Immigration, Refugees and Citizenship Canada (IRCC), and Public Services and Procurement Canada (PSPC). Other departments and agencies supported efforts under the National Strategy with pre-established funding. These partners are the Royal Canadian Mounted Police (RCMP), Global Affairs Canada (GAC), Justice Canada (JUS), and Employment and Social Development Canada (ESDC). Additionally, Statistics Canada (StatsCan) receives funding from PS for activities that support the National Strategy, including data collection and research projects.

The purpose of the evaluation was to assess the relevance, effectiveness and efficiency of the National Strategy. The evaluation covered the period from fiscal year 2019-2020 to 2022-2023 and was conducted in accordance with the Treasury Board Policy on Results and the Directive on Results.

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.

The public has grown increasingly concerned about environmental issues. However, few studies examine the perceived seriousness of environmental crimes. Those that do tend to focus on US citizens and compare crime seriousness ratings among different types of crimes, rather than examining the factors that shape perceptions of environmental crime seriousness. By employing a vignette survey among Dutch citizens (N=261), the current paper seeks to address this knowledge gap. It focuses on two such factors: (1) whether or not the environmental crime is committed intentionally, and (2) whether or not the environmental crime causes considerable harm. The results show that environmental crimes were perceived as more serious when committed intentionally and when they caused considerable harm. Furthermore, intentions affected perceived seriousness less in case of harm and harm affected perceived seriousness less in case the crime was committed intentionally. Together, these findings enhance our understanding of the factors that shape the perceived seriousness of environmental crimes.

Weather variables, like temperature and precipitation, have long been established as predictors of criminal behavior. So too have researchers established the importance of controlling for potentially criminogenic places when predicting when and where crimes will occur at micro-level units of analysis. The current study examines the role that temperature and precipitation play, along with places, in the odds of street robbery occurrence on street blocks in Cincinnati, Ohio. Using multilevel modeling, with days clustered within street blocks, our results showed that temperature, but not precipitation, predicted increased odds of street robbery occurrence, even after controlling for the presence of potentially criminogenic places. We conclude that research should continue to examine these important relationships, specifcally how weather impacts the role of places in the formation of criminal opportunities
