In criminology a lot of attention is paid to risk factors in the development of criminal behaviour. It is also not uncommon to speak of criminogenic factors. In the reported research project a monitor of relevant risk factors on an aggregated level (city, city councils and boroughs) was developed. In addition the data were combined into a so-called criminogenity index for the city of Amsterdam. The article discusses the development and results of the monitor and index. It elaborates on an article which was published earlier (TvV, 2007 (6) 2), but can be read as a stand alone article.

This article presents a study on Post-Conviction Polygraphy in the Netherlands. Importantly, it exclusively focuses on cybercrime offenders. The study was designed to systematically address the different child sexual behaviours exhibited by 38 subjects who were in treatment for possessing child abuse images. The results gave indications that post-conviction polygraphy can provide additional data to inform the development of theory in this area and contribute to the treatment, supervision and more effective containment of offending behaviour, and the reduction of future victimization.

Since the mid-90s, people can obtain ‘burglary prevention advice’ in Belgium, which means that a burglary prevention adviser will carry out a free assessment of the dwelling regarding the protection against a burglary and will recommend security measures as needed. In 2008, a large-scale survey by postal mail, commissioned and financed by the Belgian Ministry of Internal Affairs, was conducted to examine three main questions concerning burglary prevention advice in Belgium. Firstly, who receives a burglary prevention visit, or in other words what are the demographic characteristics of the citizens who obtain advice? Secondly, what is the extent to which these persons are satisfied with the visit and which elements, related to the advice, are associated with this (dis)satisfaction? Finally, do these citizens implement the proposed prevention measures and what is the role of the financial incentives (e.g. a tax deduction and an investment subsidy) concerning this implementation? Using a stratified random sample, 2,123 citizens were selected of whom ultimately 1,193 persons answered and returned the questionnaire. This paper presents the main findings of this study. We will also draw attention to the risk of an increased societal dualization and exclusion in the field of community safety when burglary prevention becomes predominantly the responsibility of the individual. The results of our survey for instance suggest that certain groups in society, namely the lower educated, tenants and apartment dwellers, are insufficiently sensitized to call upon these advisers. Furthermore, mainly the higher educated and those with higher incomes plan to make use of the possibility of tax deduction.

The literature on using Social Network Analysis (SNA) in criminological research is expanding. The SNA perspective already changed the way we look at organized crime. More often organized crime is referred to as changeable social networks instead of hierarchical structured organizations like the Italian or American mafia. In this respect, SNA seems to lack behind in empirical research on organized crime. Mainly, this is due to the lack of suitable network data on organized crime. For obvious reasons, commonly used methods of gathering network data – such as questionnaires – are less suitable for research on organized crime. Suspects of organized crime have not much to gain from talking about their ‘comrades in crime’. Alternative data need to be explored. Wiretaps from criminal investigations are one such source. In this contribution the SNA perspective is used to present an overview of the possibilities and limitations of using wiretaps for SNA. It follows that wiretaps from criminal investigations should be regarded as ego-centered network data. Therefore, research questions and objective for both criminal investigations as well as scientific research should be directed to the personal networks of suspects instead of the network as a whole.

The social network approach is gaining influence among criminologists studying organized crime and terrorism. The theoretical concept, however, still needs further elaboration. To this end, concepts developed within the field of economic sociology could provide a substantial contribution. Economic sociologists have, among other things, focused on the role of social networks with regard to the completion of economic transactions. They regard mutual trust built through personal relations as an essential part of economic transactions, particularly if these imply certain risks for the parties involved. In other words, before transactions materialize, the parties must first be able to establish trustworthy personal relations. Based on these ideas, Spapens introduced in 2006 the theoretical concept of the criminal macro network, being a social network consisting of individuals able and willing to engage in illegal activities. The capital of each member of the criminal network consists, on the one hand, of his links, defined as information relations, within the network. On the other hand, a person’s position is determined by personal knowledge and skills. It is assumed that executing an actual illegal activity – e.g. drug production, trafficking human beings, bank robbery – requires cooperation between a subset of members of the criminal network, the criminal group.An extensive study of xtc production in the south of the Netherlands between 1996 and 2004 revealed the existence of a ‘xtc network’ consisting of individuals interconnected by social relations. The macro network proved to be relatively stable over time. The composition of the criminal groups, however, changed regularly. This was not only explained by shifting business opportunities, but also by the efforts of the police and the Public Prosecution Service leading to convictions and the dismantling of criminal groups. Better knowledge of the functioning of the criminal macro network can provide valuable contributions to criminological understanding of organized crime. These insights are of course also of great practical importance for law enforcement agencies.
