Open heimelijke netwerken in de Nederlandstalige georganiseerde synthetische-drugscriminaliteit

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden synthetic drugs, poly-drug trafficking, organized crime, encrypted communication data, social network analysis
Auteurs Irma Vermeulen, Melvin Soudijn en Wouter van der Leest
SamenvattingAuteursinformatie

    In recent years, the authorities have dismantled several encrypted phone providers. These providers stored millions of messages about covert activities that were overtly exchanged between criminals. This type of communication offers a unique insight into serious organized crime and the people involved. Based on one such intercepted encrypted phone network, called PGP-Safe, we carried out a social network analysis on the Dutch-speaking synthetic drug market. Three findings stand out. Firstly, three-quarters of all accounts (N=4,158) are interconnected in a giant component, resulting in a criminal small-world effect. Secondly, the network appears to be robust. As a consequence, the removal of central accounts will hardly have any impact on the network as a whole. Thirdly, the majority of the accounts within the synthetic drug market is involved in poly-drug trafficking. The Dutch synthetic drug market is much more closely intertwined with other drug markets than is commonly known.

De doorvoer van cocaïne via Nederland

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden cocaine trafficking, ping-pong trade, poly-drug trafficking, qualitative social network analysis, transnational networks of networks
Auteurs Vanessa Dirksen, Wouter van der Leest en Irma Vermeulen
SamenvattingAuteursinformatie

    This article describes traits of the hitherto underexposed transit trade of cocaine via the Netherlands, based on a qualitative social network analysis of a diversity of data. Research findings show that the transit trade via the Netherlands is dominated by poly-drug trafficking. It is noteworthy that streams of predominantly mono-drugs are entering the Netherlands, while mainly streams of poly-drugs are leaving the country. Our research furthermore shows that cocaine intended for European markets may be transited via the Netherlands to European countries to which the cocaine was initially imported. This is what we refer to as ping-pong trade. Another characteristic of the transit trade of cocaine via the Netherlands is that the actors involved, mainly coordinate parts of the cocaine supply chain. Although different groups within the cocaine distribution chain collaborate, this does not necessarily mean they actually know each other. Taken together, the organization of the distributive trade of cocaine is in this article positioned as an interdependent transnational network of networks (NoN). We suggest that future research into the transit trade of cocaine should apply such a transnational NoN perspective to fully grasp the interdependence of the micro and meso levels of the trade and, in so doing, ultimately comprehend the effect this may have on the macro level.

Een kijkje achter de schermen: een kwalitatieve studie over het ontstaan van cybercriminele carrières

Tijdschrift Tijdschrift voor Criminologie, Aflevering 1 2021
Trefwoorden cybercrime, cyber offenders, criminal careers, online disinhibition, pathways
Auteurs Sifra Matthijsse, Wytske van der Wagen, Elina van ’t Zand e.a.
SamenvattingAuteursinformatie

    This qualitative study examines how criminal careers in cybercrime start and can be explained. Based on offender and expert interviews, the authors conclude that traditional factors linked with the initiation, such as a maturity gap (for juvenile offenders) and opportunism (for adult offenders), in combination with different types of (online) disinhibition – social, technical, situational and psychological – can explain the start of a criminal career. Features of the digital context appear to play a major role in the development of a criminal career and this requires more online supervision and education about – among other things – legal alternatives and the risks and boundaries of the online environment.

Mensenhandel en mensensmokkel op Curaçao: een crime-scriptanalyse

Tijdschrift Tijdschrift voor Criminologie, Aflevering 1 2021
Trefwoorden exploitation, crime scripting, situational crime prevention, Caribbean, Latin America
Auteurs Zahyanne Luisa
SamenvattingAuteursinformatie

    This article contains the results of a crime script analysis regarding the processes of human trafficking and human smuggling in Curaçao. The crime script analysis was conducted using data from five criminal investigations of human trafficking and seven criminal investigations of human smuggling. The results show that human trafficking in Curaçao consists of labor exploitation and sexual exploitation in bars, cafes and clubs. Young women are recruited from Colombia, Venezuela and the Dominican Republic to work as waitresses, trago girls and/or prostitutes. Once they arrive on the island, the women are dependent on the perpetrators and are subjected to exploitation In this research, two types of human smuggling have been witnessed. The first type consists of Venezuelan smugglers who transport fellow Venezuelan nationals to Curaçao by boat in exchange for payment. The second type of smugglers are Curaçao locals who rent out rooms to Venezuelans that reside on the island illegally.

Online jeugdcriminaliteit en ‘verkeerde vrienden’: wanneer is de samenhang het sterkst?

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2-3 2020
Trefwoorden cyber delinquency, cyber offenders, peer deviance, social network
Auteurs Yaloe van der Toolen MSc, Dr. Marleen Weulen Kranenbarg en Prof. dr. Frank Weerman
SamenvattingAuteursinformatie

    This article investigates whether cyber delinquent behaviour of school friends, other offline friends and online contacts is related to cyber delinquent behaviour of individuals, and whether this relation differs for cyber dependent, cyber enabled and traditional crime. We used both direct and indirect measures of cyber delinquency of friends. We employed data from the first wave of a large-scale study on the causes of online delinquency among Dutch juveniles (n=889; mean age=16.8 years). The results suggest that both direct and indirect measures of levels of friend delinquency were related to levels of individual cyber offending. However, indirect measures had a stronger association with individual online delinquency than direct measures. This suggests that respondents make incorrect estimates of their friends’ levels of online delinquency. Moreover, no differences were found in the strength of the relation between individual online offending and indirect measures of online offending of school friends, offline friends and online friends. This suggests that friends of different types all play an important role in individual online offending.

Access_open Een eerste blik op online delinquentie

Verkennend onderzoek bij Vlaamse jongeren en vergelijking met offline delinquentie

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2-3 2020
Trefwoorden online crime, juveniles, self-reported delinquency, risk profiles, prevalence
Auteurs Ena Coenen
SamenvattingAuteursinformatie

    Given that the social life of youngsters develops more and more online, attention for cybercrime has grown as well. However, no Flemish data is available yet. This study uses data from two representative samples of the Flemish youth to research the prevalence and risk profiles of on- and offline crime. Compared to offline crime, online crime is relatively limited. In addition, results showed that online offenders had the least severe risk profile, while offenders of both on- and offline delinquency had the most severe profile. For victimization, it appeared that it is important to consider individual types of offences, since complex differences were found between various crime types. These results indicate a limited, but not ignorable, occurrence of online crime, and a difference in risk profiles for offline and online crime.

‘Partners in crime’? De rol van de antropologie in de criminologie

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2-3 2020
Trefwoorden criminal anthropology, Criminology, anthropology
Auteurs Dr. Brenda Oude Breuil
SamenvattingAuteursinformatie

    Criminology, as an inherently interdisciplinary field, has built on anthropology (and other social sciences) in its development. This contribution addresses the question which insights in criminology have most been inspired by anthropology. First, it looks into the ‘criminal anthropology’ of Lombroso; then it embarks on an appreciation of the ethnographic research design within criminology (as first adopted by the Chicago School); and, finally, it assesses the link between anthropology, and cultural and global criminology. I conclude that anthropology has been valuable to our discipline on four levels: methodologically (in the importance of the ethnographic research design), theoretically (in its role in the development of symbolic interactionism and structuralism, for example), geographically (in the global scope of anthropological research), and analytically, in its experience with ‘doing ethnography’ in economically, politically and culturally embedded ways.

Criminaliteit, digitalisering en de online sociale wereld: dezelfde processen in een nieuwe sociale context?

Tijdschrift Tijdschrift voor Criminologie, Aflevering 4 2019
Trefwoorden digitalisation, crime, cybercrime, social media, online
Auteurs Prof. dr. Frank Weerman
SamenvattingAuteursinformatie

    This contribution reflects on the criminological meaning of the still ongoing trend of digitalisation. What does this mean for crime as a phenomenon and for the explanation of criminal behaviour? Not only did we see the emergence of new types of offending, also the context of crime has changed. In principle, the underlying explanatory processes can remain the same, but their application in the online world is complex and deserves further attention. Online social interactions are not only important for online crime, but also for traditional offenses. However, systematic research on how this actually takes place is scarce.

Georganiseerde misdaad in de 21ste eeuw

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2016
Trefwoorden organized crime
Auteurs Prof. dr. Toine Spapens, Prof. dr. Emile Kolthoff en Prof. dr. Wouter Stol
SamenvattingAuteursinformatie

    In the past decades, organised crime internationalised rapidly as a result of increasing mobility and ‘open’ borders. At the same time developments in information and communication technology have led to modernisation of existing types of crime and the introduction of novel ones. Finally, criminals have benefited from increasingly diversified migration streams. In the Netherlands and Belgium, organised crime appeared on the agenda in the 1990s. For a long time emphasis was on ‘trade crimes’ i.e. trafficking in drugs and humans, as well as human smuggling, followed by the production of synthetic drugs and cannabis. More recently the Low Countries are confronted by more visible manifestations of organised crime, for example rapid growth of outlaw motorcycle gangs. Criminals also try to utilise their capital to invest in businesses and real estate and to influence local politics.

Ondermijnende aspecten van georganiseerde criminaliteit en de rol van de bovenwereld

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2016
Trefwoorden undermining, organized crime, corruption, white-collar crime, integrity
Auteurs Prof. dr. Emile Kolthoff en Dr. Sjaak Khonraad
SamenvattingAuteursinformatie

    The concept of undermining or subversive crime seems to be linked undistinguishably to organized crime and both terms are sometimes used synonymously. Definitions of the phenomenon are sometimes based on its effects, while others have their focus on its manifestations. Discussion on the underlying causes is lacking. Regularly, activities that actually do not relate to undermining are labeled as such.
    This reflection critically examines and evaluates the concept of undermining. The central question is what has to be understood under the concept of undermining and, above all: what not? The phenomenon is further explored, with the aim of stimulating scientific debate and empirical research. The role of the government and other institutions in facilitating undermining is explicitly discussed as well as the possibilities to strengthen their resilience.

Daling in geregistreerde jeugdcriminaliteit

Enkele mogelijke verklaringen

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2015
Trefwoorden crime drop, juvenile suspects, trends, macro explanations, time series analysis
Auteurs Dr. André van der Laan en Dr. Gijs Weijters
SamenvattingAuteursinformatie

    In the Netherlands, from 2007 police census data show a sharp decrease in the number of suspects of crime among juveniles aged 12 to 25 years old. How to explain this decrease remains unclear. Constructionist theories suggest that changes in police census data are fully explained by changes in the law enforcement system. Normative theories argue that changes in police data can be explained by demographic, social or economic trends. In this paper, we systematically explored the (inter)national literature for macro factors that could explain changes in juvenile crime. Next, in an empirical case study of the city of Amsterdam, we explored which of these macro factors relate to changes over time in the number of juvenile suspects of crime and the types of crime they were suspected of. Due to multicollinearity of the macro factors multivariate analyses were not possible. Our results indicate that the decrease in police registered juvenile crime in Amsterdam should be explained by multiple factors. Some of these factors concern policy investments (such as focus on school drop-out and targeted law enforcement), other factors relate to socialdemographic developments which appeared coincidentally.

    The explosive growth of the Internet has led to countless new possibilities, and it opened the way for societal progress and an extensive globalization and digitization. However, the original ambition of the Internet as a free, open and neutral medium has also led to new possibilities in the field of crime. The current paper illustrates how governments dealt with the development of the Internet and it gives an explanation for why and how unintended side effects have manifested in society. Using the phenomenon of digital child abuse, this paper offers recommendations for an effective government response and for an effective detection of and fight against cybercrime.
