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.

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.

Tijdschrift Tijdschrift voor Criminologie, Aflevering 4 2020
Trefwoorden money laundering, financial facilitators, networked criminology, organized crime
Auteurs Jo-Anne Kramer, Arjan Blokland en Melvin Soudijn
SamenvattingAuteursinformatie

    The Financial Action Task Force reported that money launderers may operate in professional money laundering networks. Whether such money laundering networks operate in the Netherlands is unclear. In this article the authors therefore explore whether professional money launderers collaborate in network structures and the business-like manner in which they offer their services. Business-like refers to their involvement in multiple cases, the amount of repeat customers, and excludes family relations. The research is based on Dutch police registrations of 236 professional money launderers. Our results suggest that professional money laundering networks are indeed active in the Netherlands and that money launderers in these networks offer their services in a business-like manner to a varying extent. An important caveat to the current findings is that the criminal cases analyzed predominantly pertain drug-related offenses, leaving the existence and professionalism of money laundering networks in other types of crime, like large-scale fraud, a question open for future research.

Transitcriminaliteit en logistieke knooppunten in Nederland

Tijdschrift Justitiële verkenningen, Aflevering 5 2019
Trefwoorden Drug trafficking, airports, seaports, security checks, corruption
Auteurs Renushka Madarie MSc en Dr. Edwin Kruisbergen
SamenvattingAuteursinformatie

    The Netherlands functions as an important source and transit country for international organized drug trafficking. This is in part due to its large logistical nodes in the world economy, like the airport and the seaport. Based on in-depth analyses of sixteen cases of the Dutch Organized Crime Monitor, this article explores how drug traffickers operate at logistical nodes, in particular airports. The results demonstrate that organized crime groups deploy mainly three types of tactics to traffic drugs, namely defying, avoiding, and neutralizing security checks. Occupational embeddedness is manifested through several job-related factors. Autonomy, mobility, and the similarity between legitimate duties and criminal activities facilitate discrete engagement in organized crime activities during work time. Port employees are also attractive to organized crime groups because of their job-related social capital and knowledge.

Hier zit een luchtje aan. Over het wegwerken van afvalstoffen door co-vergisting

Trefwoorden Environmental crime, Crime script analysis, Green criminology, Waste
Auteurs Shanna Mehlbaum MSc.
SamenvattingAuteursinformatie

    Fermentation production processes for biofuel lead to sustainable energy, but the fermenters can also be used to dispose illegal wastes. Although it’s known that the fermentation business is susceptible for illegal behavior, so far little empirical research is carried out about the modus operandi and criminogenic factors. In this study a crime script analysis (CSA) is conducted to map the criminal process. This analysis shows that the true nature of the illegal waste is concealed by trading without or with falsified (transport) documents and illegal blending. Legal traders operate illegal and form the crucial connection between disposers and end receivers. Criminogenic factors, such as complexity of regulation and inspection, European policy differences and the lack of profitability of the fermenters, make the branch vulnerable for criminal behavior. Intervention options are formulated per phase of the criminal process and aim at prevention or increasing the chance being caught.

Organisatiestructuren van jihadistische netwerken in Nederland

Verschillen en overeenkomsten tussen 2000 en 2013

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2016
Trefwoorden jihadist networks, social network analysis, organizational structures, foreign fighters
Auteurs Dr. Jasper de Bie en Dr. Christianne de Poot
SamenvattingAuteursinformatie

    This paper uses social network analysis to study and compare the organizational structures and division of roles of three jihadist networks in the Netherlands. It uses unique Dutch police data covering the 2000-2013 period. This study demonstrates how the organizational structures differ between different networks. The earliest network has a hierarchical cell structure with a clear division of labour, while the later networks are horizontal and dense networks with less clear orientation on tasks. The core member types in the jihadist networks also differ. The earliest network contains international jihad veterans with clear leadership skills, while the later networks contain home-grown radicals with less status and often a lack of expertise. Furthermore, several jihadists evolve over time, when they used to be supporters, but become core members in posterior networks.

De brug tussen wetenschap en opsporingspraktijk

Onderzoek naar de toepassing van sociale netwerkanalyse in de opsporing

Tijdschrift Tijdschrift voor Criminologie, Aflevering 4 2014
Trefwoorden social network analysis (SNA), big data, criminal investigation, intelligence
Auteurs Drs. Paul Duijn en Dr. Peter Klerks
SamenvattingAuteursinformatie

    Social network analysis (SNA) has taken its place in the field of criminology, although among Dutch criminologists the emphasis remains on conceptual contributions. Meanwhile, the world of criminal investigation and intelligence has witnessed the development of a blossoming SNA-practice. The emergence of big data makes SNA an indispensable tool to exploit the oceans of data in a meaningful way. Unfortunately, when it comes to employing SNA, academia and the investigations and intelligence domains remain separated. While Dutch analysts adopt scientific ideas and concepts, they rarely contribute to the body of literature; confidential SNA reports remain inaccessible. Shedding light on over forty SNA related internal police studies, this article bridges the gap between Dutch academic criminologists and ‘pracademics’ in law enforcement.
