A long-standing critique of place-based crime prevention interventions has been that any reductions in crime are often short-lived. If researchers do not carry out longer-duration follow-ups, we cannot know for sure if the effects of these interventions will persist, decay, or even strengthen. Using a rigorous micro synthetic control design, we evaluated the long-term impacts of a large-scale, public-area closed-circuit television (CCTV) surveillance project in Newark, New Jersey. Results show that the CCTV project was associated with a statistically significant reduction of auto theft in the intermediate term (3–4 years). The reduction of auto theft approached statistical significance (p = 0.08) during the short term (1–2 years). The analysis also observed potential displacement effects, with displacement of robbery (p = 0.09) in the short term (1–2 years) and theft from auto (p = 0.06) in the long term (9–11 years) approaching statistical significance.

Policy implications

The results of this study may suggest the potential for a slightly modified view of deterrence decay. The CCTV project's effect on auto theft grew from approaching significant to statistically significant between the short-term and intermediate-term periods. Such “sleeper effects” suggest that an extended period was necessary for CCTV to generate deterrence. The deterrence decay during the long-term period did not occur until after these sleeper effects emerged, which may be understood as deterrence attenuation. Although only approaching statistical significance—and not as pronounced as the reduction of auto theft—the potential displacement of robbery and theft from auto indicates that static CCTV target areas may facilitate offenders taking advantage of nearby crime opportunities while appearing inconspicuous within CCTV viewsheds. In sum, policymakers should be mindful that research evidence limited to short-term impacts may fail to detect nuanced effects relevant for policy and public guidance.

 This article examines the role of organised crime groups (OCGs) in the organisation and commission of mortgage and property related frauds. Whilst conventionally in criminological and policing studies, serious and organised crime has been associated with the commission of violent, gang and drug-related crimes, there is an increasing focus on the collective and facilitative role that motivated ofenders and ‘professional enablers’ like lawyers and accountants have in the commission of fnancial crimes for gain. This article utilises case studies and social network analysis (SNA) of police-defned OCGs to identify the ties criminal actors have with other ‘members’ and broader connections. It considers causal agency and the social relations that exist within the OCG that support highly organised and sophisticated operational dynamics necessary to the commission and reproduction of organised fraud. In addition to a review of the current literature, empirical data was collected from regulatory enforcement proceedings, criminal prosecution fles, trial transcripts, witness statements and interviews with law enforcement, regulators, victim-lender participants and lead members of mortgage and property fraud OCGs. SNA is used to show how members collectively share motivations to plan and co-ordinate criminal behaviour for fnancial gain, communicate and collaborate on both an ongoing enterprise and individual project basis, and how recruitment strategies, based on kinship, support resilience and the ability to reproduce organised fraud. Examining the social network of mortgage fraud OCGs, including biographies, roles, responsibilities of members, including professional enablers and straw persons and the ties and interactions between them, will assist in understanding mortgage fraud. In particular, they will show how these individual, proximal and causal factors ft within the broader, macro- crime facilitative environment in which mortgage and property related frauds are organised and are capable of being reproduced.

Argentina, Brazil, Costa Rica, Japan, Jordan, Italy, Malaysia, the United States (State of New York), Singapore, Sweden, and the United Kingdom participated. In each country, local researchers conducted the study following a plan developed for the whole project. The multidisciplinary methodology included four phases: a comparative analysis of antidrug legislation, preliminary national reports, eight vignettes administered to different groups to gain information on the perceptions of the justice system, and guided interviews conducted with drug addicts. The data were quantified, and evaluation scales were constructed for purposes of comparison. Binary automatic scoring was applied to data from the vignettes and interviews. The data are shown graphically in 97 tables. Three conclusions are emphasized. First, drug abuse is apparently both quantitatively and qualitatively more serious where the system is perceived as less harsh and more permissive. Second, a significant correlation exists between knowledge of the law and the efficacy of the system. Third, a close association exists between the abuse of drugs and criminal behavior. These points are important for policymakers to consider. The studies in New York, Sweden, and the United Kingdom are outlined. Attachments include a 560-item bibliography and a list of experts and researchers involved in the study. Other publications from the United Nations Social Defense Research Institute are also listed.

“Forty Years of Scotland Yard” by Frederick Porter Wensley is an autobiographical account of Wensley’s extensive career in the Criminal Investigation Department (C.I.D.) of Scotland Yard. The book provides a detailed narrative of his experiences, highlighting significant cases he worked on, including notorious crimes like the Houndsditch murders and the Sidney Street siege. Wensley shares insights into the evolution of detective work, the challenges faced by the police, and the methods used to solve complex cases. His stories reflect the gritty reality of crime in early 20th-century London and the relentless pursuit of justice by the detectives of Scotland Yard. Throughout the book, Wensley emphasizes the importance of thoroughness, patience, and resourcefulness in detective work. He recounts various encounters with criminals, ranging from cunning burglars to violent gangsters, and illustrates how meticulous investigation and collaboration with colleagues led to successful resolutions. Wensley’s memoir also sheds light on the personal qualities required for effective policing, such as courage, integrity, and a keen understanding of human nature. His reflections offer a fascinating glimpse into the life of a detective and the inner workings of one of the world’s most famous police forces.

This open access book explores the use of technologies for urban safety and security. Rather than focusing on the technologies themselves, it provides and in-depth analysis of the complex urban transformations linked to the increasing integration of technical systems in the built environment. Interdisciplinary contributions explain how technologies can improve urban safety, whilst offering a broader discussion relative to urban, socio-economic and political factors. Against simplistic techno-solutionist ideas, the authors illustrate the role of technology as means to an end and show how technologies can widen our understanding of safety and security. Readers are introduced to issues relative to the practical implementation, development, and testing of urban technologies via numerous case studies from cities around the world.

In December 1937, one of the most horrific atrocities in the long annals of wartime barbarity occurred. The Japanese army swept into the ancient city of Nanking (what was then the capital of China), and within weeks, more than 300,000 Chinese civilians and soldiers were systematically raped, tortured, and murdered. In this seminal work, Iris Chang, whose own grandparents barely escaped the massacre, tells this history from three perspectives: that of the Japanese soldiers, that of the Chinese, and that of a group of Westerners who refused to abandon the city and created a safety zone, which saved almost 300,000 Chinese.

Drawing on extensive interviews with survivors and documents brought to light for the first time, Iris Chang's classic book is the definitive history of this horrifying episode.

Trafficking in human beings (THB) is a serious offence against personal and sexual freedom and integrity. It is often associated with legal and illegal migration flows, but this is only partly the case. It is true that irregular migration flows create a market for trafficking and exploitation, often connected to illegal migrant smuggling.1 This is why new migration flows, such as the arrival of many Ukrainian refugees in the EU, create a concern for the living conditions and the potential exploitation of migrants. On the other hand, half of the registered victims and three quarters of child victims of THB in the EU are EU nationals, with one third being registered in their own country.2 These are staggering statistics that indicate that there is a sizeable THB market within the EU that is independent of migration flows from outside the EU. The open internal borders of the Schengen zone have given rise to a specific pattern of regional trafficking that present a unique challenge to Europe.
