Cybercrime Perpetration Theories  

Theodore Curry

Theories of cybercrime perpetration seek to identify and explain the causes of individual- and/or group-level variation in the performance of cybercriminal behavior. Fundamental to this effort is a debate pertaining to whether extant theories of crime, previously developed to explain crime in the physical world, are useful for accounting for cybercrime or whether new theories, explicitly aimed at cybercrime, are needed. This debate hinges largely on the question of whether cybercrimes can be considered to be a type of crime in general, or whether there are features of cybercrime, such as the lack of physical contact between victims and offenders or the dissociative anonymity afforded by the collapse of time-space barriers that occurs in cyberspace, that sufficiently differentiate cybercrime from crime in the physical world such that new theories are needed to explain its occurrence. To date, however, scholars have relied almost exclusively on extant theory in cybercrime studies and only one new theory has been developed that focuses exclusively on cybercrime. Moreover, cybercrime theory has focused heavily on individual-level variation in cybercrime and largely ignored group-level variation, which is a shortcoming because understanding differences across, for example, different nations or political or religious groups, is an important part of the study of crime in the physical world. Another important problem is that basic facts about cybercriminals and victims (e.g., the approximate proportion of offenders who are male or female) are largely unknown due to a lack of systematically collected, representative, or longitudinal data on cybercrime—a situation that hinders the development of cybercrime theory. Research testing cybercrime theory shows support for a number of theories from the field of criminology, especially general strain, low self-control, social learning, and techniques of neutralization and drift. A notable development in this literature are findings that social learning and low self-control theories, working in an integrated fashion, are found to provide an especially useful explanation for cybercrime such that, on their own, individuals with low self-control may not engage in a great deal of cybercrime owing to the complexity that such offending often entails. However, if low self-control individuals have friends who engage in cybercrime, they may learn the skills needed to commit certain cybercrimes and, as a result, start offending at higher levels. Psychological studies also provide important results, including that cybercriminals tend to be more introverted than offenders in the physical world, which may tap into the dissociative anonymity afforded by offending in cyberspace. Psychological research also shows that individuals with higher levels of psychopathy are more involved in cybercrimes, particularly those that entail aggression or attempts to cause harm to others, and that more impulsive (a concept that is similar to low self-control in criminology) individuals engage in more cybercrime.


General Strain Theory  

Timothy Brezina

General strain theory (GST) provides a unique explanation of crime and delinquency. In contrast to control and learning theories, GST focuses explicitly on negative treatment by others and is the only major theory of crime and delinquency to highlight the role of negative emotions in the etiology of offending. According to GST, the experience of strain or stress tends to generate negative emotions such as anger, frustration, depression, and despair. These negative emotions, in turn, are said to create pressures for corrective action, with crime or delinquency being one possible response. GST was designed, in part, to address criticisms leveled against previous versions of strain theory. Earlier versions of strain theory have been criticized for focusing on a narrow range of possible strains, for their inability to explain why only some strained individuals resort to crime or delinquency, and for limited empirical support. GST has been partly successful in overcoming these limitations. Since its inception, the theory has received a considerable amount of attention from researchers, has enjoyed a fair amount of empirical support, and has been credited with helping to revitalize the strain theory tradition. The full potential of GST has yet to be realized, however, as the theory continues to evolve and further testing is required.


Police Corruption  

Leslie Holmes

Police corruption is ubiquitous and is a serious problem for numerous reasons. One is that police officers are often armed and can therefore pose a physical threat to citizens in a way that most other state officials do not. Another is that citizens typically expect the police to uphold the law and be the “final port of call” in fighting crime, including that of other state officials: if law enforcement officers cannot be trusted, most citizens have nowhere else to turn when seeking justice. Leading on from this, if citizens do not trust the police, they are much less likely to cooperate with them, resulting in higher unsolved crime rates. Yet according to Transparency International’s 2017 Global Corruption Barometer, more people pay bribes to law enforcement officers globally than to any other public officials, rendering the police the most corrupt branch of the state in many countries. Police corruption assumes numerous forms, from relatively benign but irritating demands for bribes from motorists to improper procurement procedures and—most dangerously—collusion with organized crime gangs in the trafficking of drugs, weapons, and humans, and occasionally even in contract killing. One other form of miscreancy was identified in the 1980s as largely peculiar to the police, namely “noble cause corruption.” This term, also known as the “Dirty Harry problem,” is applied when police officers deliberately bend or break the law not for personal benefit but in the belief that this is ultimately for the good of society. Many factors drive police corruption, including inadequate salaries, frustration with the leniency of the courts, opportunity, envy (of wealthy criminals), and simple greed. Combating it is no easy task, but methods that have significantly lowered corruption rates in countries such as Singapore and Georgia include reducing discretionary decision-making, radical restructuring, risk assessments, greater use of psychological testing, improving working conditions, lifestyle monitoring, civilian review, and introducing anti-corruption agencies that are completely independent of the police. But police corruption is ultimately a “wicked” problem, meaning that it is so complex and changeable that it can never be completely solved; the best that can be hoped for is that it will be brought down to manageable proportions.


Enemy Penology  

Susanne Krasmann

When Guenther Jakobs introduced the concept of “enemy criminal law” (Feindstrafrecht), or enemy penology, into the legal debate, this was due to a concern with the increasingly anticipatory nature of criminalization in German legislation in the last decades of the 20th century. Against the backdrop of a series of terror attacks in the West and the ensuing debates on how to deal with the dangers and threats of the new millennium, Jakobs’s theory gained new momentum in Germany’s public discourse and beyond. As it seems, the author himself turned the concept into a device for political intervention, declaring the notion of the enemy as indispensable for dealing with certain extreme crimes and notorious offenders, not only to prevent future crime and avert harm from society but also, and most notably, to preserve the established “citizen criminal law” (Bürgerstrafrecht): the enemy is the one to be isolated and excluded from the system. Enemy criminal law may be a peculiar legal concept. The logic of enemy penology, however, leads us to some more fundamental insights into the conundrums of liberal political thinking and attendant legal conceptions. It requires us to think about the enemy as a liminal figure that points to the preconditions and the paradoxes of our legal system. The history of criminology attests to the discipline’s struggle with penal law’s inherent limitations. And if we live today in times where exception and rule, internal security and external security, and military and police concerns increasingly overlap and intermingle in the face of ever new threats, the notion of enemy penology helps us to critically reflect on the mechanisms that drive these transformations.


Control Balance Theory  

Charles R. Tittle

Control balance theory (CBT) was developed in the mid-1990s, primarily to illustrate a particular method for building integrated theory and to show how general theories are useful in addressing various issues in studies of crime and deviance. A major theme on which the theory has been built is the idea that deficient control, a well-established classic notion, and excessive control all can have deviogenic consequences. In addition, the theory rests on expectations that sufficient explanation will necessarily involve complex arguments. Thus, CBT not only attempts to explain the phenomena within its domain, but it also challenges simplistic theories, contentions that theoretical integration is both impossible and undesirable, and neglect of contingencies in theorizing.


Situational Action Theory: Toward a Dynamic Theory of Crime and Its Causes  

Per-Olof H. Wikström

Situational Action Theory (SAT) is a general, dynamic, and mechanism-based theory of crime and its causes. It is general because it proposes to explain all kinds of crime (and rule-breaking more generally). It is dynamic because it centers on analyzing crime and its changes as the outcome of the interactions between people and their environments. It is mechanism-based because its explanation focuses on identifying key basic processes involved in crime causation. SAT analyzes crime as moral actions and its explanation focuses on three basic and interrelated explanatory mechanisms: the perception–choice process (the situational mechanism) that explains why crime events happen; selection-mechanisms that explain why criminogenic situations occur; and mechanisms of emergence that explain why people develop and change their crime propensities (psychosocial processes), and why places develop and change their criminogeneity (socioecological processes).


Crime Control, Community Relations, and Barriers to Community-Based Reforms in Policing  

Kevin Petersen and Danielle S. Rudes

Efforts to prevent crime often involve high concentrations of police presence in disadvantaged minority communities. When combined with aggressive enforcement and proactivity, these efforts may negatively affect police–community relations. There is often a tendency to view community relations and crime reduction as discrete goals; however, citizen cooperation is an important component of efficient crime control. Policing strategies that incorporate problem-solving and community involvement show promise in their ability to simultaneously reduce crime and improve community relations. Despite the growing number of police agencies that report implementing these strategies, however, police–community relations have not shown widespread improvement. Organizational frameworks help to identify factors that might lead police agencies to prioritize enforcement and crime control over community relations, as well as the organizational barriers to effective community-based reform. A reliance on efficiency and centralized authority, resource dependency, and symbolic legitimacy all may help to explain police agencies’ lack of effective community-based reform efforts.


Theory and Green Criminology  

Kimberly L. Barrett and Rachelle F. Marshall

Green criminology refers to a perspective within criminology that, broadly speaking, is devoted to the study of crime against and harms to the natural environment. Initially, green criminology was introduced as the study of environmental harm from a political-economic vantage point and was informed by theories from critical, radical, and political-economic (e.g., “conflict paradigm”) perspectives. Over time, however, new definitions of green criminology have emerged, as have new terms for the criminological study of environmental crimes (e.g., “conservation criminology”). These developments have invited new theoretical interpretations of environmental crime and justice. While conflict theories still maintain a degree of centrality in green criminology, the perspective has expanded to include mainstream theoretical orientations (e.g., “classical paradigm,” “consensus/positivist paradigm”) as well.


Police Officer Suicide  

John M. Violanti

All too often we emphasize the dangers of police work, but seem to neglect the hidden psychological danger of this profession. Suicide is a consequence of that hidden danger. It is a clear indication of the intolerable strain placed on the police officer’s work and life roles. Policing is an occupation replete with stress and traumatic incidents. For example, witnessing death, encountering abused children, and experiencing violent street combat weigh heavily as precipitants to depression, alcohol use, and suicide among police. Ideas as far back as Freud’s aggression theory relate to the police because officers cannot legally express anger and aggression outwardly and turn it within. Following Freud, other studies examined the frustration of police work and how it was turned inward. Other theoretical ideas concerning police suicide that have emerged over the years are included in this article—police cultural socialization, strain theory, and interpersonal suicide theory. Scientific research on police suicide has helped to focus on this topic. Much research is on suicide rates in an effort to determine the scope of this problem. Several recent studies are discussed in this article, including a national study. Such studies, however, are not without controversy and more work is necessary to clarify the validity of findings. There is lack of data available on police suicide, which adds to the problem of research. Many believe that causes of police suicide are really no different than those in other groups in society, such as relationship problems, financial difficulties, or significant loss. While scholars cannot yet be certain that police work is an etiological suicide risk factor, we can with some assurance state that it serves as a fertile arena for suicide precipitants. Culturally approved alcohol use and maladaptive coping, firearms availability, and exposure to psychologically adverse incidents all add to the suicide nexus. Last, and most important, the issue of police suicide prevention is discussed. Likely the biggest challenge in prevention is convincing officers to go for help. The police and societal culture at large attach a stigma to suicide which is difficult to deal with. Additionally, the police culture does not allow for weakness of any kind, either physical or psychological. Several promising prevention approaches are discussed. Given the reluctance to report the deaths of police officers as suicides unfortunately leaves us in a position of “best guess” based on what evidence we can collect. Looking to the future, the development of a national database focused on police suicide would help to establish the actual scope of this tragic loss of life. Interventions need to more efficaciously target at-risk police officers. More research, using longitudinal study designs, is needed to inform interventions and, in particular, to determine how suicide prevention efforts can be modified to meet the unique needs of law enforcement officers.


Bank Robbery in Popular Culture  

Chad Posick

Bank robbery is an uncommon, but highly fascinating, type of crime. The media often focus on bank robberies, especially if an event was violent or involved weapons. However, data show that bank robberies are generally uneventful—rarely involving weapon fights or injured bystanders. Instead, perpetrators tend to use verbal or written commands to obtain their money. Movies and video games depict the unusual bank robberies, which are violent and deadly because they are exciting and action-filled, which appeals to the public. Although generally a misrepresentation of empirical reality, media depictions can highlight criminological theory in action and bring to light issues around impulsivity, thrill-seeking, brain development, group behavior, and the behavioral consequences of social strains.


Biosocial Theories in Criminology  

Jessica Wells and Anthony Walsh

While the roots of criminology largely lie in sociological explanations for crime and delinquency, a resurgence has begun wherein human behavior is explained as a product of both environmental and biological factors: biosocial criminology. Biosocial criminology encompasses many perspectives that seek to explain the relationships between human behavior and genes, evolution, neurobiology, and more. While biosocial criminology does not have a long history in the broader field of criminology, modern advances in technology have made access to data to explore biosocial criminological questions far more readily available. Advanced technology, coupled with studies suggesting that a large proportion of the variance in antisocial behavior is attributable to genetic factors has spurred many criminologists to explore how both nature and nurture influence behavior. A wide variety of perspectives is apparent within biosocial criminology. These perspectives can be seen as tools to uncover different elements of the equation seeking to understand human behavior. Behavior genetic studies seek to explain what proportion of the variation in a trait or behavior is due to genetic factors. Molecular genetic studies seek to uncover which genes are related to that trait or behavior and how strongly they are associated. Evolutionary psychology seeks to explain why a trait or behavior emerged and remained through the process of natural selection. Neurobiological studies explain how the complex structure and function is related to traits and behavior. While these perspectives vary widely in their approach, one fact remains: neither environmental nor biological explanation for human behavior is sufficient on its own; rather, the complex interplay between environments and biology is critical to advance knowledge about the causes and correlates of criminal and delinquent behavior.


Developmental and Life-Course Theories of Crime  

Tara Renae McGee and David P. Farrington

Developmental and life-course theories of crime are collectively characterized by their goal of explaining the onset, persistence, and desistance of offending behavior over the life-course. Researchers working within this framework are interested not just in offending but also in the broader category of antisocial behavior. Their research aims to investigate the development of offending and antisocial behavior throughout life; risk and protective factors that predict this development; the effects of life events; and the intergenerational transmission of offending and antisocial behavior. While there have been a number of developmental and life-course theories of crime, the more influential and empirically tested ones include Sampson and Laub’s age-graded informal social control theory and Moffitt’s typological model of life-course-persistent and adolescence-limited offending. While developmental and life-course criminology has come to be viewed a single type or grouping of criminology, there are distinctions between the more sociological life-course perspectives and the more psychological developmental perspectives. These are a result of the disciplinary training of the individuals working in the field and are reflected in the types of variables examined and the theoretical explanations developed and applied to explain the relationships. The broader life-course perspective focuses on the examination of human lives over time, with an understanding that “changing lives alter developmental trajectories,” according to Glen Elder in his 1998 work. Life-course approaches to studying human development are not unique to criminology and are represented within many disciplines, such as medicine and epidemiology. There are four central themes of the life-course paradigm: the interplay of human lives and historical times; the timing of lives; linked or interdependent lives; and human agency in making choices. Therefore the life-course perspective within criminology focuses on the examination of criminal behavior within these contexts. Given its sociological origins, life-course theoretical explanations tend to focus more on social processes and structures and their impact on crime. Developmental perspectives within criminology tend to be more psychological in nature, and its theoretical explanations tend to focus more on individual characteristics and the impact of familial processes on the individual. Both of these perspectives require longitudinal data, that is, data collected over time for each individual. Collectively, developmental and life-course criminology allow for the examination of: within-individual changes over time; the impact of critical life events; the importance of the social environment; and pathways, transitions and turning points.


Gangsters and Genre  

Anita Lam

While there are multiple possible definitions of what makes a gangster film, ranging from the simple inclusion of a villainous gangster in a film to those that follow outlaws on the run, the classic definition of a gangster film has revolved around the rise and inevitable fall of an immigrant gangster protagonist, a career criminal with whom audiences are expected to identify. Yet this classic definition has been expanded by evolving theoretical and methodological considerations of film genre. From the outset, gangster films were one of the first film genres to be considered by early genre criticism. Based on structural and formal analyses of the so-called Big Three Hollywood gangster films from the 1930s—namely, Little Caesar, The Public Enemy, and Scarface—early scholars argued that the gangster genre reflected the ideological tensions that underlay the American Dream of material success. Interpreted as modern tragic figures, gun-toting gangsters in these films were trapped in dangerous cities characterized by anonymity, violence, and death. More recently, genre criticism of gangster films has not only shifted emphasis away from the classic gangster narrative, but also paid far greater attention to institutional intertexts that have highly influenced the production and historical reception of these films. By highlighting variability, contingency, mutability, and flexibility, scholars now speak of genre in terms of specific cycles of production, where each cycle produces different gangster figures to mediate changing societal concerns and public discourses around issues of criminality, class, gender, and race. More contemporary and culturally-specific extensions, adaptations, or articulations of the gangster genre can also be read as thematic explorations of blackness in the following two ways. First, the cycle of ghetto-centric American “hood” films in the 1990s, a cycle that helped to launch hip-hop cinema, points to a continuity between the mythic figure of the gangster and African-American self-representations as “gangsta.” Secondly, while the gangster genre has been defined as a distinctly and explicitly American genre, owing much to critics’ primary emphasis on examining Hollywood films, the genre has also played a significant role in revitalizing and popularizing Hong Kong cinema in the late 1980s and 1990s. Referred to as hak bong dianying (“black gang films”), Cantonese-language Hong Kong gangster films are part of the fabric of local Hong Kong culture, revealing the moral implications of joining “black society” (the Cantonese-language concept for triad) and the “black paths” that members take.


Developmental and Life-Course Perspectives on Gangs  

Molly Buchanan, Elise T. Simonsen, and Marvin D. Krohn

With distinct advances since the 1980s, developmental, life-course criminology has expanded to become one of the most prominent subdivisions in the field of criminology, as the knowledge gained from this perspective has propelled the field forward. Although studies of gangs and gang membership predate the emergence of developmental, life-course criminology, the proliferation of research in both of these areas shares many parallels. Furthermore, increased applications of developmental, life-course perspectives to gang-related research, as well as scholars’ continued efforts to generate life-course-rooted theories specific to gang delinquency, can and have benefited the study of gangs. Some of the life-course models and theories commonly applied in studies of gangs include Sampson and Laub’s age-graded theory of informal social control, Hawkins and colleagues’ social developmental model, Thornberry and Krohn’s interactional theory, and Howell and Egley’s developmental model of gang membership. The foundation of each of these theories is the life-course perspective, the thrust of which demonstrates the utility of following individuals, or gang members, throughout their lives. Viewing gang-related issues through a developmental, life-course lens further permits studying gang membership from multiple time points and angles and has allowed for theoretically rooted analyses of the precursors to gang joining, experiences while being gang involved, and factors related to gang exiting. For example, studies have found that, in general, the “timing” of most gang joining aligns well with the average onset of criminal careers, both typically occurring during early to mid-adolescence. Studies informed by the developmental, life-course perspective have also explored the periods during which individuals are actively engaged in their gang activities and identities, along with members’ abrupt or gradual gang-exiting processes (i.e., desistence). Overall, research guided by these models and theories has established myriad consequences of gang membership in the short-term and over the life course. The findings have been integral in informing new and continuing gang-related prevention and intervention efforts, as well as in highlighting relevant topical arenas in need of continued scholarly attention.


Self-Control Theory and Crime  

Michael Gottfredson

Gottfredson and Hirschi advanced self-control theory in 1990 as part of their general theory of crime. Self-control is defined as the ability to forego acts that provide immediate or near-term pleasures, but that also have negative consequences for the actor, and as the ability to act in favor of longer-term interests. An individual’s level of self-control is influenced by family or other caregiver behavior early in life. Once established, differences in self-control affect the likelihood of delinquency in childhood and adolescence and crime in later life. Persons with relatively high levels of self-control do better in school, have stronger job prospects, establish more stable interpersonal relationships, and attain higher income and better health outcomes. Self-control theory was initially constructed to reconcile the age, generality, and stability findings of criminological research with the standard assumptions of control theory. As such, it acknowledges the general decline in crime with age, versatility in types of problem behaviors engaged in by delinquents and offenders, and the generally stable individual differences in the tendency to engage in delinquency and crime over one’s life-course. Self-control theory applies to a wide variety of illegal behaviors (most crimes) and to many noncrime problem behaviors, including school problems, accidents, and substance abuse. A considerable amount of research has been undertaken on self-control theory and on Gottfredson and Hirschi’s general theory of crime. As a result, self-control theory is likely the most heavily researched perspective in criminology during the past 30 years. Most reviews find substantial empirical support for the principal positions of the theory, including the relationship between levels of self-control and delinquency, crime, and other problem behaviors. These relationships appear to be strong throughout life, among most groups of people, types of crime, in the United States and other countries, and over time. The posited important role of the family in the genesis of self-control is consistent with substantial bodies of research, although some researchers argue in favor of important genetic components for self-control. The theory’s expectations about the age distribution of crime, versatility of offending, and stability of individual differences over long periods of time also receive substantial support. Researchers have long studied variations in age effects, particularly seeking continuously high levels of offending for the most serious offenders, but reviewers have found that the evidence for meaningful variability is not convincing. For public policy, self-control theory argues that the most promising approach for crime reduction focuses primarily on prevention, especially in early childhood, and secondarily on situational prevention for specific types of crimes. Gottfredson and Hirschi argue that self-control theory is inconsistent with reliance on the criminal justice system to affect crime levels. On the one hand, general reviews of the empirical literature on deterrence and incapacitation support the expectations of self-control theory by finding little support for severity of sanctions, sanctions long removed from the act, and selective incapacitation for “serious offenders.” On the other hand, experimental studies from education, psychology, and criminology generally support the idea that early-childhood family and educational environments can be altered to enhance self-control and lower expected delinquency, crime, and other problem behaviors later in life.


Deviant Subcultures in European Context  

Alexandra Stupperich, Helga Ihm, and Shannon B. Harper

Since the late 1950s, criminological research has focused on the question of why particular groups are more likely to become involved in criminal and/or deviant behavior. Theories about subcultures start from the premise that smaller sub- or countercultural groupings exist within a larger society and differentiate themselves by developing their own moral precepts, values, and norms. Subcultural theories were originally developed in the United States and have a long theoretical tradition dating back to the 1930s. Structural-functionalist sociologist Albert Cohen in 1955 first used the term, “delinquent subculture.” In his book Criminal Youth, Cohen defined subculture as the sum of dominant knowledge, convictions and beliefs, conventions, preferences, and prejudices within and acquired by participation in the particular group. Deviant behavior arises when these values and norms run counter to those of the dominant culture. Cohen interpreted delinquency as a collective, practical, and quick solution to problems caused by unequal opportunities in the class system. The basic assumption of early subcultural theories was that members of the lower socioeconomic classes established their own value system and norms due to their inability to conform to middle-class values and norms and achieve middle-class goals. Later in the 1970s, subcultural theory was altered and further expanded by the Centre for Contemporary Cultural Studies (CCCS) at Birmingham University. The CCCS posits that criminal subcultures favor delinquency due to intersecting attitudes such as the rejection of authority, hedonism, or sensation-seeking. Moreover, the relationships between members within a subculture are important due to the shared nature of values, norms, and identities. Regionality is no longer a criterion for a delinquent/criminal subculture due to modern Europe’s high level of mobility and digital networks. Instead, modern delinquent/criminal subcultures utilize social media outlets not limited to region to disseminate their values and norms and establish identity. Islamic fundamentalism and the Reich Citizens and Sovereign Citizens movements are examples of subcultures that utilize the Internet to rapidly spread programs and ideologies in a targeted and simple manner. While earlier subcultural studies tended to explain the relationship between subculture and criminality as due to frustration over social and economic inequality, more recent research argues that subcultural theories need to be macro-level focused. Consequently, recent scholarship frames subcultural criminality as an expression of groups’ social and material life, which are defined by stylistic factors such as intentional communication, homology, and specific (piecemeal) solutions to problems.


Group-Based Trajectory Modeling  

Thomas W. Wojciechowski

Group-based trajectory modeling (GBTM) is a variant of growth mixture modeling that has risen to prominence in the field of criminology as a useful method for understanding heterogeneity in developmental patterns of outcomes of interest. The method entails identification of a trajectory model that best fits a set of longitudinal data and is comprised of a set number of trajectory groups of varying complexity that participants are assigned membership to. Following identification of a best fitting model, extensions of the method can then be used to better understand nuances of the developmental outcome of interest. The use of particular extensions of the method then relies on the research question. These extensions may be used to identify predictors of differential development, understand how differential development predicts a later outcome, or understand how development of another outcome predicts concurrent development of the outcome of interest. While the GBTM method has been demonstrated to have a high degree of utility for modeling criminological outcomes of interest, there remain a number of notable gaps in the manner in which it has been applied in the field. Given the general shift toward a life-course understanding of criminology, there remain numerous areas where GBTM may be useful for advancing existing criminological theories within this paradigm. While not an exhaustive list, social control theory, social learning theory, general strain theory, and the dual systems model are all examples of criminological theories which may be particularly amenable to the use of GBTM to better understand nuances of development of constructs of interest and advance the perspectives on criminogenic processes that these theories currently offer. These issues indicate the continued need for examination of relationships of interest using GBTM and related extensions of the method within the field of criminology.


Wildlife Crime  

Rachel Boratto and Carole Gibbs

Wildlife crime is an area of study typically defined from a legalistic perspective as an act in contravention of laws protecting wildlife. These crimes occur both within and across national borders and may include trafficking in wildlife or wildlife products. Internationally, wildlife crime is regulated by a series of conventions, with CITES being the most important for the regulation of trade. While these conventions are international in scope, they must be administered by signatory nations through domestic laws. Domestic laws are enacted within local contexts and are as varied as the crimes themselves, regulating hunting, transportation, use, and sale of wildlife. Several international organizations (e.g., INTERPOL) facilitate collaboration between countries, but these organizations do not have law enforcement authority, so enforcement occurs primarily at the domestic, state, and regional level, following the domestically enacted law. Scholars have taken a variety of approaches to define and understand various types of wildlife crime and criminals. Some have used a stage-based approach to develop typologies of wildlife crime based on the location of the crime or the criminal within the supply chain, while other criminal typologies are based on underlying motivations. In addition to typological approaches, more general theoretical frameworks (e.g., opportunity theory) have been used to explain these motivations and drivers of crime. More broadly, wildlife crime can be situated and understood within overarching theoretical perspectives, including Green Criminology and Conservation Criminology. Green criminologists define wildlife crime in terms of harm to animals, regardless of whether the act was against the law, and examine how power and inequality produce these harms. Conservation Criminologists, on the other hand, advocate taking an interdisciplinary approach to systematically define and understand environmental risks, including those related to wildlife. The diversity of perspectives and approaches has produced a wildlife crime literature that is extremely varied, ranging from research on hunting and poaching to trafficking and enforcement. The continued pursuit of novel theoretical perspectives and methodological practices is necessitated by persistent criminal threats to wildlife, particularly to endangered species. Scholar must therefore continue to develop, test, and refine theory and methodological approaches in order to empirically guide wildlife conservation strategy.


Gang Joining  

James A. Densley

This article examines the who, what, where, when, why, and how of gang joining. The question of what youth join when they join gangs speaks to the contested nature of gang definitions and types and the consequences of gang membership, specifically heightened levels of offending and victimization. The type of gang and the obligations of membership influence the joining process. Where youth join gangs, namely, the neighborhood and social context, also impacts individual opportunities and preferences for joining. When youth join gangs is considered in a developmental sense, to include both adolescent and adult onset, in order to account for continuity and change in individual levels of immersion or “embeddedness” in gangs across the life course. Who joins gangs provides a profile of gang membership grounded in the well-documented risk factors for gang membership, but limited by problems of prediction. Why youth join gangs speaks to the push and pull factors for membership, the appeal of gangs, and the selective incentives they offer. Still, motivations for gang membership cannot fully explain selection into gangs, nor can general theories of crime that do not necessarily fit with general knowledge of gangs. How youth join gangs, for example, is more complicated than initiation rites. The mechanisms underlying the selection process can be understood through the lens of signaling theory, with implications for practice.


White-Collar Delinquency  

Andrea Schoepfer

Studies of white-collar crime have largely focused on the crimes and immoral and unethical actions of adults during the course of their legitimate occupations, yet adults are not the only offenders, and white-collar crimes don’t always require employment. By narrowing the focus to who can offend, we may miss out on a fuller understanding of the phenomenon. The specific category of “white-collar delinquency” has been proposed to address this gap in the research. The original conceptualization of white-collar delinquency focused on crimes of juveniles that are of major financial and social consequence. The concept largely focuses on computer crimes, fraud, and crimes of skill, including piracy, securities fraud, espionage, denial of service attacks, hacking, identity fraud, dissemination of worms and viruses, and other crimes that can result in serious economic harm. Just as juveniles engage in conventional street crime offenses as do adult offenders, they also possess the ability to engage in white-collar offenses as do adult offenders, and there is a need to study the two age groups separately, as motivations, influences, and opportunities may differ. The literature thus far has largely ignored juvenile involvement in white-collar crimes due to the nature of the phenomenon, the reliance on offender-based definitions, and the presumption of opportunities to engage in the actions. Some white-collar offenses that were historically committed exclusively by adults have a place in the juvenile community as well. This “migration” has taken place for a number of reasons, with the majority of them closely tied to the nearly limitless access juveniles currently have to technology. Due to the overwhelming popularity of personal computers in homes and marked advancements in technology, opportunities for hybrid white-collar crimes (e.g., credit card fraud, identity theft, hacking, phishing, general fraud, intellectual property theft, financial/bank fraud) have dramatically increased, yet criminological studies focusing on technology related crimes have, until recently, been relatively sparse, and studies of fraud have predominately focused on characteristics of the victims as opposed to the offenders. As access to computers and the internet grow, so too do opportunities to engage in these types of crimes. Juveniles are able to interact with others from the privacy of their own homes with the benefit of complete anonymity. This anonymity may contribute to the appeal of computer-related delinquency, as such acts involve almost no confrontation and no violence, and are individualistic in nature. These individualistic crimes may attract those who would normally avoid more conventional crimes that involve confrontation. Technology has opened the door for a new type of offender and new types of offending. Although it is difficult to identify an exact dollar amount, financial losses from serious computer crimes such as audio, video, and software piracy; security breaches; and intellectual property theft are likely to exceed the financial losses from conventional crimes, and it is therefore imperative that more attention be given to these types of crimes and perpetrators. Theoretical explanations for this new category of crime have not yet been fully explored for many reasons. First, technology advances much faster than the laws regulating behavior. Second, apprehension and prosecution for crimes of technology are relatively low, and thus little data exists for theory testing with these crimes and offenders. Finally, computer and technology crimes fall into a gray area; they are not necessarily either property crimes or traditional white-collar crimes. In criminology, computer crimes tend to fall into a “hybrid” or “other” category of white-collar crime and as such are often ignored in studies on white-collar crime. Furthermore, juveniles are often overlooked in white-collar crime research due to their status and limited access to opportunity. By proposing the term “white-collar delinquency,” researchers hope to bring more focus to the understudied topic of juveniles engaging in crimes of serious economic consequence.
