In the present study, the role of genetic and cultural transmission in intergenerational continuity of rule-breaking behavior (RBB) was investigated. Based on the resemblance within 3,982 Dutch twin pairs, aged 13 to 17 years, the relative importance of genetic (G), shared environmental (C), and unique environmental (E) influences on RBB was estimated. Cultural transmission, the process of passing on knowledge, norms and values, can lead to similarities within families, and forms part of the shared environment of children growing up in the same family. The authors found no evidence for shared environmental influences, and consequently no indication of a role for cultural transmission. Genetic influences explained 60 percent of the variance in rule-breaking behavior at age 13 to 17, implying that intergenerational continuity at this age is mainly driven by genetic transmission.

Last year the article ‘Episodic memory and interviewing witnesses. What do police interviewers know about this topic?’ (Odinot, Boon & Wolters, 2015, TvC, 57(3), 279-299) was published in this journal. The article describes a study that explored the knowledge of police interviewers about episodic memory. The researchers concluded that police interviewers had insufficient knowledge of episodic memory and that this was related to the lack of psychological terms in the manual of the curriculum of police training. In this article we describe the lack of scientific consensus about episodic memory and the consequences of this for doing research with lists with theses about this subject. Differences between interviewing witnesses and suspects will be discussed. We also question whether it is necessary that police interviewers have thorough knowledge of episodic memory. More important is what knowledge does police need when doing interviews and how are these conducted? Some factors have a negative impact on the quality of those interviews, so we end up with some recommendations for improving the quality of interviews in police practice.

In this study, we examined what police interviewers know about factors that affect the reliability of eyewitness testimony. We asked 143 specialist investigative interviewers from the Dutch police to complete a questionnaire about eyewitness memory. The results indicate that the police interviewers have limited knowledge of episodic memory and accompanying interviewing issues. In addition, we analyzed the interview manual from the Dutch Police Academy on coverage of the topics in our questionnaire. The poor level of knowledge of the police interviewers was correlated with lack of knowledge in the manual. Results are discussed in relation to education in police interviewing in the Netherlands.

The detention experiences of male criminal foreign national prisoners without legal residence receive little attention in penological literature. A qualitative study amongst 30 prisoners with and 16 prisoners without legal residence in the penitentiary institution Tilburg shows that contacts with the social network and the preparation of the reintegration in society are (more) complicated for foreign national prisoners without legal residence. Besides, communication with the staff is more difficult for this group. These factors have negative impact on their detention experiences. The results show that both deprivation and importation theory apply to foreign national prisoners without legal residence. However, importation aspects – especially the lack of legal residence – may substantially and systematically increase the deprivation and result in additional exclusion and isolation mechanisms for this particular group.

How can police officers make use of citizens’ religious beliefs when dealing with cases of honour-based violence (HBV)? In this article religion is addressed regarding motive and legitimisation of violence and as a social network of people and institutions for communities of believers. We focus on Islamic religion, because most cases of HBV handled by the police take place within Islamic communities and because the Dutch public debate on religion revolves around Islam. We interviewed police officers with expertise on HBV. These officers have an instrumental vision on religion. It helps them to gain insight in motives for violence and it offers opportunities for conflict mediation and coping with the aftermath of HBV.

During the Second World War, a large number of prisoners were put to work in concentration camps in order to contribute to the development of Germany. As this labour became more important in economic terms during the years 1939 to 1945, the death toll in the camps also rose during the same period. This contribution aims at providing insight into the apparent contradiction (paradox) between the practices of extermination on the one hand and the German economic interests on the other hand. Not only has historiography paid relatively little attention to this phenomenon (it is not a main topic), criminology has also remained remarkably silent during this debate. Looking at the ‘plantation’ in Dachau concentration camp (1937-1945) we develop an exploratory analysis of the subject. Using Vaughan’s organizational criminology, we discuss the paradox and address the question of the extent to which criminology can offer explanations for phenomena of this kind.

This article focuses on migration with criminal motives. Two specific groups are discussed, British migrants in the Netherlands and Dutch migrants in Spain. Little is written on criminal migration motives in combination with Western subjects. On the other hand, investigative authorities have first-hand knowledge on this matter. An analysis of 25 closed case files shows that within these two groups of migrants, some people are heavily involved in the international drugs trade. Although their numbers are small, their function is important. Through their actions it becomes possible for certain cities or areas to evolve into international criminal drug marketplaces. There are also some differences between British and Dutch criminals abroad. British criminals are often involved as brokers. They broker drugs for third parties in Great Britain. Their stay in the Netherlands seems temporarily. They do not invest in the economy or buy property. Conversely, Dutch criminals in Spain could be described as leaders of organized crime groups. They invest in Spain by buying companies and property.

Starting a decade ago, police authorities in Western Europe have been dealing with (South)Eastern European gangs coming over to Western Europe. These gangs commit a large number of property crimes and are characterised by their high level of mobility. Yet, this raises questions as to how their mobility has to be interpreted: is it temporary, making them criminal tourists, or are there any migration mechanisms involved? This article is based on interviews with offenders charged with selling criminal goods (i.e. fencing). Fencing activities appear to take place either in Western Europe or in the countries of origin. Alongside these activities, their centre of social activity appears to be located in either one of them as well. This heterogeneity indicates there is little added value in combating the Eastern European crime gangs, because different offender types with a different background are involved.
