“The physical origin of such abnormalities of the mind as are called ‘criminal’ is a comparatively new idea….It has not been long since insanity was treated as a moral defect….”My main effort is to show that the laws that control human behavior are as fixed and certain as those that control the physical world…”

“Immediately after the awful barbarism which disgraced the State of Georgia in April of last year, during which time more than a dozen colored people were put to death with unspeakable barbarity, I published a full report showing that Sam Hose, who was burned to death during that time, never committed a criminal assault, and that he killed his employer in self- defense.”

This is the classic work of the “father of criminology” Cesare Lombroso translated from the Italian by his daughter Gina Lombroso. Here was the idea of the “born criminal” and a detailed classification system according to body types and other physiological and physical features. The major work was “L’Uomo delinquente” that emphasized the atavistic origins of criminality.

Garofalo, a student of Lombroso, attempted to formulate a sociological definition of crime that would designate those acts which can be repressed by punishment. These constituted "Natural Crime" and were considered offenses violating the two basic altruistic sentiments common to all people, namely, probity and piety.

Giant clams are a traditional source of subsistence protein for coastal communities across Asia and Pacific regions. In recent decades, however, giant clams have been subject to poaching and commercial harvesting. Now viewed as high-value luxury food item, giant clams are also in demand in the international aquarium trade, and their shells are sought after for the ornamental carving industry. The Wildlife Justice Commission is concerned that giant clam shells are being used as a substitute for elephant ivory. Since China’s 2017 ban on the domestic elephant ivory trade, giant clam shells are an increasingly popular ivory alternative. These factors are likely to have contributed to the overexploitation and rapid decline of giant clam populations throughout many of their natural habitats. This not only puts increased pressure on the vulnerable giant clam, but also perpetuates demand for “premium” ivory products, sustaining the threat to elephant populations in the wild. Giant clams may not be as immediately charismatic as, say, elephants or rhinos, but they play a valuable role in maintaining healthy coral and oceans. Preventing biodiversity loss and preserving ocean eco-systems are crucial in the fight against catastrophic climate change.

Wildlife trafficking is a growing global concern. It takes place in all regions of the world with those nations with high biodiversity being the source and the consumers of the wildlife as well as transit areas and hubs for smuggled wildlife. It is a significant contributor to biodiversity loss and species extinction. Many if not most developing nations are rich in biodiversity and therefore must contend with wildlife trafficking. It is a critical concern for these nations’ environment and economies. It has been documented that corruption is an essential component in the facilitation and perpetration of the illegal wildlife trade, but a comprehensive study into the scale, scope and structure has yet to be undertaken. This U4 Issue paper conducts a meta-study regarding corruption’s role in wildlife trafficking from the available literature, interviews with experts and a case study of Vietnam in an attempt to highlight concerns for bilateral donors in regards to conservation, environment and law enforcement programmes.

"Wildlife trafficking threatens the existence of many plant and animal species and accelerates the destruction of wildlife, forests, and other natural resources. It contributes to environmental degradation, destroys unique natural habitats, and deprives many countries and their populations of scarce renewable resources. Nevertheless, preventing and supressing the illegal trade in wildlife, animal parts, and plants is presently not a priority in many countries and it remains overlooked and poorly researched. The chapters included in this volume address causes, characteristics, and actors of wildlife trafficking, analyse detection methods, and explore different international and national legal frameworks."

Chemicals provide important benefits to society and play a vital role in the global economy, but they also carry risks for the environment and human health, with greater risks to vulnerable social groups. Chemicals can contaminate soil, air and water and can damage biodiversity, and human exposure to chemicals is implicated in a range of acute and chronic health effects. As industries have grown in recent decades, so too have environmental and health concerns, and now a range of multilateral environmental agreements together with initiatives, non-binding legal instruments, national legislation and policy frameworks regulate the trade in chemicals

While conservation practitioner anecdotes and existing empirical research all point to corruption as a main facilitator enabling wildlife crime, there is still limited knowledge about what can change this situation and help reverse the pernicious impact of corruption on conservation outcomes in practice. Corruption has a negative impact on conservation by reducing the effectiveness of conservation programmes, reducing law enforcement and political support, as well as establishing incentives for the overexploitation of resources. It undermines the effectiveness and legitimacy of laws and regulations and can be an indicator of the presence of organised crime groups. Corruption needs to be addressed as a central part of the approach to tackling wildlife crime.

The paper revisits the local determinants of crime using a spatial model distinguishing between resident and non-resident offenders. Employing data for German municipalities, the model is estimated by means of a spatial GMM approach. Focusing on resident offenders legal earnings opportunities and the expected gain from offenses are found to be important determinants of crime. Also the socio-economic background in terms of unemployment, poverty, and inequality proves significant for both property and violent crime. Whereas local inequality only shows an effect on crime committed by resident offenders, crime committed by non-resident offenders is shown to be significantly related to the characteristics in adjacent municipalities such as unemployment and income.

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 paper studies the effects of the introduction of a new mass medium on criminal activity in Germany. The paper asks the question of whether highspeed internet leads to higher/lower sex crime offences and murder. I use unique German data on criminal offences and broadband internet measured at the municipality level to shed light on the question. In order to address endogeneity in broadband internet availability, I follow Falck et al. (2014) and exploit technical peculiarities at the regional level that determine the roll-out of high-speed internet. In contrast to findings for Norway (Bhuller et al., 2013), this paper documents a substitution effect of internet and child sex abuse and no effect on rape incidences. The effects on murder increase under the instrumental variable approach however remain insignificant. Overall, the estimated net effects might stem from indirect effects related to differences in reporting crime, a matching effect, and a direct effect of higher and more intensive exposure to extreme and violent media consumption. After investigating the potential channel, I do find some evidence in favor of a reporting effect suggesting that the direct consumption effect is even stronger. Further investigation of the development of illegal pornographic material suggests that the direct consumption channel does play a significant role in explaining the substitution effect.

According to the European Parliament, unemployment, social disintegration, the lack of an integrative policy, and the worsening of urban services and living conditions cause frustration and despair, especially among economically and socially disadvantaged groups, and constitute unfavourable conditions that might lead to delinquent behaviour. Furthermore increasing poverty and inequality are supposed to be crime-enhancing factors. Based on this view, the European Commission has put out to tender a research project titled "Development and validation of scientific indicators of the relationship between criminality, social cohesion and economic performance" which has been executed by ZEW during the period 1/12/1998 - 29/2/2000. The present publication provides the results obtained from this project. The study intends to contribute to a better understanding of the interactions between criminality, economic performance and social cohesion. We try to achieve this aim by evaluating the existing economic and criminological research (with a special focus on quantitative research) and by carrying out own empirical investigations on the basis of a panel consisting of national time series from the 15 EU member states, an international cross-section of nations and an unique set of regional panel data originating from eight EU member states. Our empirical results about causes of crime reveal the crime reducing potential of intact family values. A smaller number of divorces and earlier marriage significantly reduce delinquency. By the same token, less efficient child care as a consequence of lacking family cohesion might explain the crime enhancing effects found for increasing female labour force participation rates. Further evidence supporting the interdependence of crime and the labour market show up in significant parameter estimates for indicators of unemployment, fixed-term contracts and part-time working. Furthermore, we find that higher wealth is associated with higher property crime rates and more drug-related offences, and that in turn drug offences foster the incidence of property crime.

“The perpetrator isn’t from here!” This claim is an understandable defensive response exhibited by local people following a sexual homicide,1 particularly in cases involving a child victim. The contention is grounded more in belief than in knowledge, however, as very few of the perpetrators who are later identified travelled a great distance to the crime scene. One occasionally encounters this notion in police circles as well, and it often makes the process of identifying the perpetrator even more difficult. When cases of this kind remain unsolved, the investigating unit in charge frequently requests the appropriate operational case analysis unit to perform a case analysis.2 As a rule, such cases analyses include the development of an offender profile containing, to the extent possible, statements about the unidentified perpetrator’s probable age, prior criminal record and place or region of residence. These criteria within the offender profile are of utmost importance to local investigative authorities. On the basis of a combination of these criteria, which can be researched in databases, analysts can, for example, identify a group of potential suspects and/or establish a scale of priorities within a known group of suspects (keyword “profiling”).

Uganda occupies a critical position as a logistics hub for transnational flows of illegally sourced wildlife. As a source, consolidation and transit country, it acts as a nexus state – a ‘one-stop shop’ for criminals looking to illegally buy and sell wildlife, launder the proceeds, and tie this in with other illicit activity, from trafficking in timber to drugs. In this context, illegal wildlife trade (IWT) in Uganda is highly lucrative for criminals. Yet, little is known about the associated money flows, despite strong momentum to address the finances of IWT at a global level. In parallel, little research has assessed Uganda’s record in disrupting these flows. While the country has taken tangible steps to target the finances of IWT, the effectiveness of its actions has not yet been analysed. Based on 35 semi-structured interviews with key stakeholders, a rigorous review of open-source literature and analysis of confidential information, this paper assesses the relationship between IWT and illicit finance in Uganda and considers how effectively the country is responding to these threats. In doing so, the paper represents the most in-depth independent study of a single jurisdiction’s experience of and response to the finances of IWT to date.

Dominant scholarly approaches to drug trafficking violence (DTV) in Mexico generally explain its onset and escalation by focusing on one of four issues: a) the democratisation process in the 1990s and 2000s; b) the systemic corruption of the judicial and legislative institutions; c) a weak rule of law across the country; and d) the ‘war on drugs’ launched by former president Felipe Calderón (2006-2012). These approaches, however, fail to account for the discursive conditions that enable the perpetrators to engage in DTV. This thesis, therefore, proposes a new critical approach to our understanding of DTV by examining the life stories of thirty-three former narcos collected in Mexico between October 2014 and January 2015. Using a discourse analytical approach, I identify a set of meaning production regularities, uncovered through detailed interviews, which I conceptualise as narco discourse. In this discourse, informed by a neoliberal ethos, poverty is understood as a fixed condition, ‘poor people have no future’ and have ‘nothing to lose’. Under this logic, the ‘only’ way for them to enjoy life is to engage in illegal activities conceived as ‘la vida fácil’ [the easy life] which guarantee them ‘dinero fácil’ [easy money]. The narco discourse also produces the idea that ‘un hombre de verdad’ [a true man] embodies the normative characteristics of machismo. This masculinity, in turn, justifies male violence as ‘necessary’ in order to ‘survive’ in contexts of poverty. These three intertwined discourses of poverty, masculinity and violence enable the construction of DTV in instrumental terms, e.g. as ‘un negocio’ [a business’], as something ‘exciting’ and even as a source of empowerment. In this way, I demonstrate how DTV is discursively made possible by and for former narcos. This is a starting point for rethinking DTV not only as the result of corruption, or failed policies, but also as the product of the interplay between pre-existing social conditions and discourses produced and reproduced by perpetrators of DTV.

By focusing attention on individuals rather than on aggregates, this book takes a novel approach to studying criminal behavior. It develops a framework for collecting information about individual criminal careers and their parameters, reviews existing knowledge about criminal career dimensions, presents models of offending patterns, and describes how criminal career information can be used to develop and refine criminal justice policies. In addition, an agenda for future research on criminal careers is presented.

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.
