Through its own investigations and intelligence analysis, the Wildlife Justice Commission has also collected evidence of criminal networks that are dealing in wildlife alongside other illicit commodities. This report aims to present some of these examples, along with information collected from open sources, to contribute to the knowledge base on this issue. It sets out 12 case studies that illustrate a range of converging crime types and typologies that have transpired in different regions of the world to increase the understanding of how these intersections can occur on the ground. The case studies include six cases involving the trafficking of terrestrial wild animals, three cases involving fisheries crimes, and three cases involving timber crimes (although they are collectively referred to as wildlife crime throughout the report). The cases demonstrate that criminal groups may have a range of motivations to diversify their activities and engage in wildlife or other types of crime Convergence can occur opportunistically on an adhoc basis, as a complete “career shift” in response to changing conditions, or as part of a diversification strategy to increase profits across a range of illicit commodities. It can also occur transactionally when criminal groups in different markets exchange goods or services with each other or could be embedded to such an extent that the crimes are inextricably linked.

With access to and usage of it increasing dramatically over the past 20 years, the Internet has become an emerging realm for human interaction. With children constituting one-third of Internet users worldwide, this realm offers endless opportunities to learn, connect, and interact. At the same time, the Internet facilitates child sexual abuse on a large scale – through the production, dissemination, and accessing of child sexual abuse material.This study aims to critically analyse emerging aspects of the international and national regulation, investigation and prosecution of online child sexual abuse material from a child-rights and rule-of-law-based approach. It investigates emerging aspects of substantive and procedural law which have been little explored in the past, zooming in on complex constitutional aspects by applying a comparative legal analysis approach with a strong focus on the Global South as well as interdisciplinary legal research.In order to solve these complex legal issues, the answer lies in the identification and subsequent navigation of a variety of dichotomies that govern the discourse on online child sexual abuse material. The international and national regulation, investigation and prosecution of emerging aspects of online child sexual abuse material hence require constant identification, reflection and calibration of competing discourses, with a view to developing a cyber-specific yet victim-sensitive response that upholds the rule of law and takes a child-centred approach.

Most psychological studies report a positive relationship between violent video game play and aggression. In line with that researchers and policy makers alike understand playing violent video games as contributing factors to increased aggression in teenagers and young adults including, perhaps, high school shootings. However, laboratory studies are unable to account for either the possible selection of relatively violent people into playing violent video games or foregone aggressive effects of alternative activities video game playing may substitute for. Specifically, psychological laboratory experiments cannot address the time use effects of video games which tend to incapacitate gamers from violent activity, e. g. crimes, by drawing them into extended gameplay. Accordingly, laboratory studies may be poor predictors of the net effects of violent video games on society, thus potentially overstating the importance of video game induced aggression. We argue that as both a behavioral tendency toward aggression and incapacitation from aggression are consequences of playing violent video games, the policy relevance of violent video game regulation depends critically on the degree to which one outweighs the other. We empirically investigate how video games could affect crime using four years of weekly data from the US by matching four different data sources. The number of violent and nonviolent crime incidents each week we obtain from the National Incident Based Reporting System (NIBRS). Our measure for video game play is derived from VGChartz which report the unit sales of the top 50 video games across the US each week. To determine the violent content of each game, we collect information from the Entertainment Software Rating Board (ESRB). This nonprofit body rates the appropriateness of games and provides detailed content descriptions for each game including the degree of violence. To control for unobserved factors that might influence both crime rates and video game play like, e. g., bad weather such as rain or heavy snow, we focus only on changes in game sales associated with differences in game quality as measured by Gamespot, a professional video game rating board (instrumental variable approach). Our results indicate two opposing effects. They suggest the behavioral effects in line with the psychological studies. If not for the incapacitation effect, violent video games would be associated with more violent crimes. However, the results also support a voluntary incapacitation effect in which playing either violent or non-violent games decrease crimes. Sales of either violent or non-violent games are associated with decreased violent and non-violent crime. The incapacitation effect dominates the behavioral effect such that, overall, violent video games lead to decreases in violent crime.

This report summarises the findings from a five year research project, the Sussex Hate Crime Project, funded by the Leverhulme Trust. The aim was to examine the indirect impacts of hate crimes – how hate attacks on members of a community affect the thoughts, emotions and behaviours of other members of that community. The project focused on hate crimes targeted against LGB&T and Muslim communities and used a variety of different research methods, including questionnaire surveys, individual interviews and social psychological experiments.

Research on human trafficking and organised crime is relatively rare in Finland. During the recent years human trafficking, procuring and prostitution have been studied i.a. in a legal perspective (Roth 2007a; 2007b; 2008), in relation to cross-border prostitution (Marttila 2004; 2005a; 2005b; 2006; 2008), and in the context of commercialisation of sex (Jyrkinen 2005). The problems of identifying the victims of human trafficking (Putkonen 2008) and trafficking in women and illegal immigration (Lehti and Aromaa 2003) have also been examined, as well as the effects of globalization on the sex industry in Finland (Penttinen 2004). In addition, Finnish sex-workers (Kontula 2008), prostitution in Northern Finland (Skaffari and Urponen 2004; Korhonen 2003), sex bars (Lähteenmaa and Näre 1994; Näre and Lähteenmaa 1995; Näre 1998), and sex buyers (Keeler & Jyrkinen 1999) have been the focus of recent research. Also organised pandering and prostitution in Finland was studied in the beginning of the 2000s (Leskinen 2003). Organised crime is scrutinised by Junninen (2006) and Bäckman (2006). However, the connection between human trafficking and organised crime has not been a central focus of any specific recent study in Finland. It also seems that prostitution and procuring markets have changed during the recent years and because of this, new studies on the issue are needed. Although human trafficking, prostitution and organised crime have been researched extensively in the global context, in this report we refer mainly to the earlier Finnish studies. The aim is to provide a comprehensive view of the Finnish prostitution-related human trafficking situation in the context of organised crime. We approach the topic from a sociological perspective and with qualitative methods. This study covers the first decade of the 21st century.

The threats arising from different types of cybercrime are real and constantly evolving, as the internet with its anonymity and borderless reach provides new opportunities for physical and virtual criminal activities. We can see complex cybercriminal networks connecting subgroups and also single individuals that are active on, through and against the internet. At the same time there are also ‘offline’ criminal organisations using the internet to facilitate their activities and to increase their profit. Even so-called ‘traditional’ organised crime groups are widening their criminal portfolios by committing cybercrime. By constantly evolving online opportunities, their acts of ‘traditional crimes’ become even more far-reaching and damaging, thus benefiting the criminal organisation. It is not only the involvement of organised crime in cybercrime that is dangerous, but also cybercrime committed in an organised manner. Cyber-OC represents the convergence of these two phenomena. Despite the huge threat arising from its cumulative character, Cyber-OC is frequently underestimated and differently defined even by law enforcement authorities.

Why do offenders often become victims of crime themselves? And are victims of crime also more likely to become criminal offenders? While criminological research often treats victims and offenders as distinct groups, Von Hentig already in 1948 noted that these groups may overlap. In his textbook, The Criminal and His Victim, Von Hentig criticized the traditional offender=oriented nature of criminology and drew attention to the fact that victims and offenders both play important roles in criminal events and people may alternate between the role of victim and offender. Subsequently, numerous studies have examined the relationship between victimization and offending and virtually all documented a strong connection between the two: those who engage in criminal offending are often also the ones who suffer from it (Fagan, Piper, & Cheng, 1987; Jennings, Piquero, & Reingle, 2011; Jensen & Brownfield, 1986; Lauritsen & Laub, 2007; Lauritsen, Sampson, & Laub, 1991; Ousey, Wilcox, & Fisher, 2011; Sampson & Lauritsen, 1990; Singer, 1981; Smith & Ecob, 2007). Despite the strong empirical evidence for the victimization-offending relationship, the etiology of this relationship is still not well understood. The aim of this study is therefore to provide more insight in the underlying processes that explain this victim-offender overlap.

Most major crime in this country emanates from two major data sources. The FBI’s Uniform Crime Reports has collected information on crimes known to the police and arrests from local and state jurisdictions throughout the country. The National Crime Victimization Survey, a general population survey designed to cover the extent, nature, and consequences of criminal victimization, has been conducted annually since the early1970s. This workshop was designed to consider similarities and differences in the methodological problems encountered by the survey and criminal justice research communities and what might be the best focus for the research community. In addition to comparing and contrasting the methodological issues associated with self-report surveys and official records, the workshop explored methods for obtaining accurate self-reports on sensitive questions about crime events, estimating crime and victimization in rural counties and townships and developing unbiased prevalence and incidence rates for rate events among population subgroups.

The Bureau of Justice Statistics' (BJS) National Crime Victimization Survey (NCVS) measures the rates at which Americans are victims of crimes, including rape and sexual assault, but there is concern that rape and sexual assault are undercounted on this survey. BJS asked the National Research Council to investigate this issue and recommend best practices for measuring rape and sexual assault on their household surveys. Estimating the Incidence of Rape and Sexual Assault concludes that it is likely that the NCVS is undercounting rape and sexual assault. The most accurate counts of rape and sexual assault cannot be achieved without measuring them separately from other victimizations, the report says. It recommends that BJS develop a separate survey for measuring rape and sexual assault. The new survey should more precisely define ambiguous words such as "rape," give more privacy to respondents, and take other steps that would improve the accuracy of responses. Estimating the Incidence of Rape and Sexual Assault takes a fresh look at the problem of measuring incidents of rape and sexual assault from the criminal justice perspective. This report examines issues such as the legal definitions in use by the states for these crimes, best methods for representing the definitions in survey instruments so that their meaning is clear to respondents, and best methods for obtaining as complete reporting as possible of these crimes in surveys, including methods whereby respondents may report anonymously.

Rape and sexual assault are among the most injurious crimes a person can inflict on another. The effects are devastating, extending beyond the initial victimization to consequences such as unwanted pregnancy, sexually transmitted infections, sleep and eating disorders, and other emotional and physical problems. Understanding the frequency and context under which rape and sexual assault are committed is vital in directing resources for law enforcement and support for victims. These data can influence public health and mental health policies and help identify interventions that will reduce the risk of future attacks. Sadly, accurate information about the extent of sexual assault and rape is difficult to obtain because most of these crimes go unreported to police. Estimating the Incidence of Rape and Sexual Assault focuses on methodology and vehicles used to measure rape and sexual assaults, reviews potential sources of error within the NCVS survey, and assesses the training and monitoring of interviewers in an effort to improve reporting of these crimes.

Crime is a major problem in society as, for instance, indicated by the most recent report of the Security Monitor.1 According to this monitor, almost 2.5 million citizens in the Netherlands were victimized in 2016 by either a property crime (11.5%) or a violent crime (2.3%). Yet, the Security Monitor does not register how many of these victims were first-time victims or repeat victims. Dutch studies into the prevalence of repeat victimizations, although rather out-dated, suggest that repeat burglary victimization is a serious issue to tackle in the Netherlands (e.g. Arends, 1997; Eijken & Van Overbeeke, 1998; Hakkert & Oppenhuis, 1996; Kleemans, 2001; López, 2001; Tseloni, Wittebrood, Farrell & Pease, 2004; Wittebrood, 2006). For example, Hakkert and Oppenhuis (1996) reported that 21% of the burglary victims have to deal with another burglary within a year and that these repeat burglary crime victims account for 44% of all (attempted) burglaries (see also Kleemans, 2001; Tseloni et al., 2004). In addition, repeat violent crime victimization may also be an important issue. Hakkert and Oppenhuis (1996), for example, reported that about 43% of victims of violent crime face another violent crime victimization within a year – accounting for 77% of all violent crimes (see also Police Monitor Population, 1999). These figures should be seen as a low estimate, because many victims do not report their victimization.

This report aims to increase our insight into the explanation of cyber-delinquency among juveniles. We examined which individual characteristics and environmental factors are related to different types of cybercrime, with a specific focus on the importance of peer relationships. We used a longitudinal research design (three waves of data collection) among a substantial sample of Dutch youths in secondary or tertiary education (with ages between 12 and 25), who were following ICT programmes, tracks, or courses. These students were chosen because they are considered to be at an elevated risk of committing cybercrime. We used questionnaires to collect self-report data on a large variety of cyber-offences, and on characteristics of both offline and online peers. We distinguished between cyber-dependent offending (i.e. offences requiring the use of online means) and cyber-enabled offending (i.e. offences existing in the offline world, but that can also be conducted online). We also included questions about common traditional types of offending. In addition, we asked the respondents about various individual characteristics and environmental factors and we collected detailed social network data on the respondents’ school friends. Our methods (for details, see Chapter 3) addressed various important limitations in previous research on cyberdelinquency (see Chapter 2).

Child sex tourism is a growing problem and a relatively new challenge for the Dutch national police, which is faced with the task of combatting child sexual abuse by Dutch citizens abroad. Little is known about travelling child sex offenders. In this literature review, information from (international) scientific research, Dutch policy reports, and other documents is analyzed to investigate the characteristics, motives and techniques (modus operandi) of (Dutch) child sex tourists. We conclude that this offender group is not homogeneous, and that different motivations (preferential/situational) and modus operandi (short stay/long stay/online) apply. The diversity of the offender group requires a variety of initiatives which are well-adjusted to the different offender types. The scarcity of research on this topic furthermore illustrates the necessity to gather more intelligence and conduct follow-up research.

Victim reports are the main source of information for the police regarding where crimes are committed, and also the basis for most subsequent actions of the criminal justice system. Therefore, the victims' decision to report to the police is crucial. However, much criminal victimization is not reported and, consequently, many offenders are never prosecuted. Why are some crimes reported and others not? Substantial differences in reporting are found across crime locations, neighborhoods and countries. In this book, a socio-ecological model of victims' decision-making is introduced which endeavors to explain these contextual differences in reporting. To empirically test the main hypotheses derived from this model, several data sources are used and different research strategies are employed, with which the effects of crime, victim and contextual factors on victims' reporting behavior are simultaneously analyzed. Factors constituting the context in which crime incidents take place (e.g. whether the location is in the private or public domain), as well as factors composing the neighborhood context (e.g. the neighborhood social cohesion) and – to a lesser extent – the country context in which victims reside, were found to play a role in victims's decision (not) to report.

How does crime develop over the life course? And how do age, life circumstances, and prior offending affect this development? This thesis seeks to answer these two questions that are central to present day developmental and life course criminology. The research presented is based on the Criminal Career and Life course Study (CCLS), a longitudinal study covering the criminal careers of over 5,000 offenders from early adolescence to late adulthood. Employing a range of statistical techniques especially designed for analyzing longitudinal data, this research gives insight in issues such as the reality of life course persistent offenders, the influence of marriage and parenthood on offending, and the role of prior offending in generating stability and change in offending over time.

This study explores contexts of disorder and crisis, in which criminal actors gain legitimacy. By affirming that criminal groups are already social agents, this research argues that they gain political legitimacy to the extent that criminal groups engage in an authority-building process. Thus, it focuses on two instances in which criminal groups launched campaigns— or at least engaged in planned activities— in order to gain political and social legitimacy. La Familia Michoacana (LFM) and Los Caballeros Templarios (LCT) de Michoacán in Mexico, on the one hand, and Cosa Nostra (CN) in Italy, on the other, offer rich and instructive cases to examine. Precisely, the research asks for how these groups seek to forge legitimacy, as well as for what are their strategies for that purpose. The research opens two avenues of conceptual discussion.

In Ports, Piracy, and Maritime War Thomas K. Heebøll-Holm presents a study of maritime predation in English and French waters around the year 1300. Following Cicero, pirates have traditionally been cast as especially depraved robbers and the enemy of all, but Heebøll-Holm shows that piracy was often part of private wars between English, French, and Gascon ports and mariners, occupying a liminal space between crime and warfare. Furthermore he shows how piracy was an integral part of maritime commerce and how the adjudication of piracy followed the legal procedure of the march. Heebøll-Holm convincingly demonstrates how piracy influenced the policies of the English and the French kings and he contributes to our understanding of Anglo-French relations on the eve of the Hundred Years’ War.

Even though England, Ireland, Scotland, and Wales were under a common Parliament in the nineteenth century, cultural, economic, and historical differences led to very different values and assumptions about crime and punishment. For example, though the Scots were the most likely to convict accused killers, English, Welsh and Irish killers were two and a half times more likely to be executed for their crimes. In Certain Other Countries, Carolyn Conley explores how the concepts of national identity and criminal violence influenced each other in the Victorian-era United Kingdom. It also addresses the differences among the nations as well as the ways that homicide trials illuminate the issues of gender, ethnicity, family, privacy, property, and class. Homicides reflect assumptions about the proper balance of power in various relationships. For example, Englishmen were ten times more likely to kill women they were courting than were men in the Celtic nations.

By combining quantitative techniques in the analysis of over seven thousand cases as well as careful and detailed readings of individual cases, the book exposes trends and patterns that might not have been evident in works using only one method. For instance, by examining all homicide trials rather than concentrating exclusively on a few highly celebrated ones, it becomes clear that most female killers were not viewed with particular horror, but were treated much like their male counterparts.

The conclusions offer challenges and correctives to existing scholarship on gender, ethnicity, class, and violence. The book also demonstrates that the Welsh, Scots, and English remained quite distinct long after their melding as Britons was announced and celebrated. By blending a study of trends in violent behavior with ideas about national identity, Conley brings together rich and hotly debated fields of modern history. This book will be valuable both for scholars of crime and violence as well those studying British history.

Over the past two decades considerable interest has developed in the subject of the victims of crime. This interest reached a peak in 1982 with the establishment and report of the President's Task Force on Victims of Crime (1982), which made numerous recommendations for legislative, executive, and other institutional action on both the federal and state levels, including an amendment to the United States Constitution. However, the momentum continued. Subsequent developments have included the establishment of an Office for Victims of Crime in the Office of Justice Programs, a flurry of legislative activity across the nation, and the declaration of National Crime Victims' Rights weeks with the participation of the U.S. president. The interests of victims have been taken up not only by special organizations established for the purpose, such as the National Organization of Victims' Assistance (NOVA), the Victims' Assistance Legal Organization in Virginia, and the National Victim Center (founded in honor of Sunny von Bulow), as well as more narrowly focused groups such as MADD (Mothers against Drunk Driving), but also by such mainstream professional bodies as the American Bar Association (ABA), the National Association of Attorneys General, the National Conference of the Judiciary, the American Psychological Association, and the National Institute for Mental Health. Landmark legislation at the federal level includes the Victim and Witness Protection Act of 1982, the Victims of Crime Act of 1984, and the Victims' Rights and Restitution Act and other related provisions of the Crime Control Act of 1990. (See also the Attorney-General's Guidelines for Victim and Witness Assistance, issued in pursuance of the 1982 and the 1990 acts.)

Illicit drugs continue to be a profitable area for criminal organizations operating within the EU. Drug use and drug markets can act as facilitators for all types of violence, which could ultimately lead to homicide. Yet, drug-related homicide (DRH) has not been monitored. The development of a drug-related homicide data collection is necessary to study this phenomenon. This report provides a first step towards a European-level DRH monitor.

Most of the academic literature on violence in Nigeria is qualitative. It rarely relies on quantitative data because police crime statistics are not reliable, or not available, or not even published. Moreover, the training of Nigerian social scientists often focuses on qualitative, cultural, and political issues. There is thus a need to bridge the qualitative and quantitative approaches of conflict studies.This book represents an innovation and fills a gap in this regard. It is the first to introduce a discussion on such issues in a coherent manner, relying on a database that fills the lacunae in data from the security forces. The authors underline the necessity of a trend analysis to decipher the patterns and the complexity of violence in very different fields: from oil production to cattle breeding, radical Islam to motor accidents, land conflicts to witchcraft, and so on. In addition, they argue for empirical investigation and a complementary approach using both qualitative and quantitative data. The book is therefore organized into two parts, with a focus first on statistical studies, then on fieldwork.
