The Strategic Prevention of Gun Violence Among Gang‐Involved Offenders

Problem‐oriented policing has been suggested as a promising way to understand and prevent complex gang violence problems. A number of jurisdictions have been experimenting with new problem‐oriented frameworks to understand and respond to gun violence among gang‐involved offenders. These interventions are based on the “pulling levers” deterrence strategy that focuses criminal justice and social service attention on a small number of chronically offending gang members responsible for the bulk of urban gun violence problems. As part of the US Department of Justice‐sponsored Project Safe Neighborhoods initiative, an interagency task force implemented a pulling levers strategy to prevent gang‐related gun violence in Lowell, Massachusetts. Our impact evaluation suggests that the pulling levers strategy was associated with a statistically significant decrease in the monthly number of gun homicide and gun‐aggravated assault incidents. A comparative analysis of gun homicide and gun‐aggravated assault trends in Lowell relative to other major Massachusetts cities also supports a unique program effect associated with the pulling levers intervention.     

The impact of gun control and gun ownership levels on violence rates

What effects do gun control restrictions and gun prevalence have on rates of violence and crime? Data were gathered for all 170 U.S. cities with a 1980 population of at least 100,000. The cities were coded for the presence of 19 major categories of firearms restriction, including both state- and city-level restrictions. Multiple indirect indicators of gun prevalence levels were measured and models of city violence rates were estimated using two-stage least-squares methods. The models covered all major categories of intentional violence and crime which frequently involve guns: homicide, suicide, fatal gun accidents, robbery, and aggravated assaults, as well as rape. Findings indicate that (1) gun prevalence levels generally have no net positive effect on total violence rates, (2) homicide, gun assault, and rape rates increase gun prevalence, (3) gun control restrictions have no net effect on gun prevalence levels, and (4) most gun control restrictions generally have no net effect on violence rates. There were, however, some possible exceptions to this last conclusion—of 108 assessments of effects of different gun laws on different types of violence, 7 indicated good support, and another 11 partial support, for the hypothesis of gun control efficacy.     

Is the Nexus of Gang Membership,Exposure to Violence,and Violent Behavior a Key Determinant of First Time Gun Carrying for Urban Minority Youth?

Two waves of longitudinal data from a high-poverty sample of minority youth living in extreme poverty was used to determine if the nexus (or intersection) of gang membership T1, exposure to violence T1, and violent behavior T1 is a precursor of first time gun carrying T2. The findings indicated a significant amount of overlap between gang membership, exposure to violence, and violent behavior. The multivariate findings also revealed that: (1) the effect of exposure to violence T1 on initiation of gun carrying T2 became non-significant after controlling for gang membership T1 and violent behavior T1; and (2) only 1.8% of youth were part of the nexus of gang membership T1, exposure to violence T1, and violent behavior T1, but they were 665% more likely to initiate gun carrying T2. The theoretical and policy implications of the findings for the prevention of youth gun violence as well as areas for future research are also discussed.     

Sociological measurement confusion,paradigmatic imperfection,and etiological nirvana: Striking a pragmatic balance in pursuing science

Extant gang research supports an enhancement effect of membership on delinquency; that is, while delinquent youths may be attracted to gangs, it is also true that gang membership increases delinquency among youths and that while delinquency levels decrease after gang membership, they do not decrease to nongang levels. In this paper, we build on this research, examining the relationship between youth gang membership and violent victimization in a general sample of adolescents. We find that gang member victimization rates are higher than nongang member rates, not only during membership, but before and after as well. Thus an enhancement model of gang membership appears to best fit both offending and victimization rates. This effect of gang affiliation on victimization goes beyond gang members' involvement in violent offending; violence and gang status equate with cumulative disadvantage in terms of violent victimization. Additionally, contrary to gang youths' perceptions, gangs appear to offer no protective value to gang members; we find no differences in violent victimization between youths who joined gangs for protection and those who joined for other reasons, either before or after joining.     

Risky Firearms Behavior in Low-Income Families of Elementary School Children: The Impact of Poverty, Fear of Crime, and Crime Victimization on Keeping and Storing Firearms

This report examines possession and storage of firearms in low-income urban families with at least one child between 8 and 12 years of age. The data primarily consisted of responses to a survey administered to parents, but these data were supplemented by records obtained from discussion groups composed of children between 8 and 12 years of age. The data were collected from five low-income neighborhoods in a medium sized city in the Pacific Northwest as part of a larger study focusing on the presence of risk factors for substance abuse, violence, and gang activity. All five neighborhoods are known to be plagued by poverty, violence, substance abuse, and gang activity. To make our findings more understandable, we compared our findings from these neighborhoods to similar data from a middle-class neighborhood. Middle-class parents were twice as likely to have firearms in their homes, but were much less likely to keep them loaded and/or unlocked. High rates of victimization, fear of crime, self-protective behavior, and exposure to threats or attacks were associated with keeping firearms for protection and engaging in risky gun behavior in the home.     

Prison gang integration and inmate violence

Purpose

Gang membership has been linked in a number of prior studies with inmate misconduct; known gang members are more prone than non-gang members to act violently behind bars. Theories of intergroup conflict suggest, however, there is reason to expect that broader within-prison gang dynamics, not just gang membership alone, are associated with the incidence of violence.

Methods

We collected data on inmates from a large southern state and estimated multilevel models of inmate-on-inmate violence. Included in our models were a variety of common individual-level correlates of violent misconduct, among them gang membership. Substantive prison-level correlates included the percentage of gang members and “gang integration,” the latter being a measure of gang heterogeneity.

Results

We found a modest association between both gang variables and inmate-on-inmate violence, with gang integration being the most significant of the two.

Conclusions

Gang membership is an important correlate of inmate violence, but attention to broader prison gang dynamics is clearly necessary. We discuss the implications of this finding for theories of inmate violence.     

THE TRADE IN TOOLS: THE MARKET FOR ILLICIT GUNS IN HIGH‐RISK NETWORKS

Illegal guns circulating among high‐risk networks represent a threat to the security and well‐being of urban neighborhoods. Research findings reveal that illegal firearms are usually acquired through a variety of means, including theft and diversions from legitimate firearms commerce. Little is known, however, about the underground gun markets supplying the gang and drug networks responsible for a large share of gun violence in U.S. cities. In this article, we take a mixed‐methods approach, combining trace analyses of recovered handguns with ethnographic interviews of high‐risk gun users to develop new insights on the entry of guns into three criminal networks in Boston. We find that guns possessed by Boston gang members are of a different character compared with other crime guns; these guns are more likely to be older firearms originating from New Hampshire, Maine, and I‐95 southern states. The results of our qualitative research reveal that gang members and drug dealers pay inflated prices for handguns diverted by traffickers exploiting unregulated secondary market transactions, with significant premiums paid for high‐caliber semiautomatic pistols. Taken together, these findings provide an analytic portrait of the market for illicit guns among those most proximate to violence, yielding novel empirical, theoretical, and practical insights into the problem of criminal gun access.     

Interpersonal violent crime in Ghana: The case of assault in Accra

This study examined the trends, patterns, and socio-spatial conditions and factors that foster assaultive incidents and behaviors in Accra, Ghana. Specifically, the study examined how much assaults occurred over time, background characteristics of the victims and offenders, victim-offender relationships, and the housing units that recorded the most assaults. Among the triggers of assaults were females in familial settings and neighborhood propinquity, that is, disputants related through kinship, residential proximity, and contractual obligations. Arguments, drunkenness name-calling, jokes, funerals, inheritance, property, festivals, chieftaincy, communal living and sharing, such spatial factors as transient populations and routine activities were among the remote and immediate causes of the assaultive incidents. Among the housing units, the compound houses recorded the highest assaults. The majority of the victims and suspects were young males, between eighteen and thirty-four years, unemployed or in low paying blue-collar jobs. The majority of the assaults occurred in Accra Central, the precinct with the most compound homes and lower-class neighborhoods, followed by Nima, Kaneshie, and Kpeshie. Most assault incidents occurred in the morning, between 6:00 a.m. to 9:00 a.m. and in the afternoon, between 5:00 p.m. to 7:00 p.m.     

The Concentration and Stability of Gun Violence at Micro Places in Boston, 1980–2008

Boston, like many other major U.S. cities, experienced an epidemic of gun violence during the late 1980s and early 1990s that was followed by a sudden large downturn in gun violence in the mid 1990s. The gun violence drop continued until the early part of the new millennium. Recent advances in criminological research suggest that there is significant clustering of crime in micro places, or “hot spots,” that generate a disproportionate amount of criminal events in a city. In this paper, we use growth curve regression models to uncover distinctive developmental trends in gun assault incidents at street segments and intersections in Boston over a 29-year period. We find that Boston gun violence is intensely concentrated at a small number of street segments and intersections rather than spread evenly across the urban landscape between 1980 and 2008. Gun violence trends at these high-activity micro places follow two general trajectories: stable concentrations of gun assaults incidents over time and volatile concentrations of gun assault incidents over time. Micro places with volatile trajectories represent less than 3% of street segments and intersections, generate more than half of all gun violence incidents, and seem to be the primary drivers of overall gun violence trends in Boston. Our findings suggest that the urban gun violence epidemic, and sudden downturn in urban gun violence in the late 1990s, may be best understood by examining highly volatile micro-level trends at a relatively small number of places in urban environments.     

Intimidation and Street Gangs: Understanding the Response of Victims and Bystanders to Perceived Gang Violence

While research routinely examines the influence of gang membership on the quantity of violent crime involvement, less is known about the influence of gang violence on the situational characteristics of violent victimization. Felson’s discussion of street gangs highlights the possible functional role gang membership plays in the commission of violent crime; what he terms “the street gang strategy.” This study examines the functionality of gang membership during violent crimes by investigating the influence of perceived gang membership on the likelihood of victim resistance, bystander intervention, and police reporting using data from the National Crime Victimization Survey. Findings offer little support for the idea that gang members intimidate victims and bystanders to the extent that their behavior during and after violence differs systematically from responses resulting from non‐gang violence. Results are discussed in terms of their policy relevance and implications for future research.     

Facilitating Violence: A Comparison of Gang-Motivated, Gang-Affiliated, and Nongang Youth Homicides

It is well established that gangs facilitate violent offending by members,but the mechanisms by which that facilitation occurs remain unclear. Gangsmay promote violence indirectly by facilitating members' access to riskysituations such as drug markets or directly through gang functions such asturf defense. We explore alternative modes of facilitation in a comparisonof gang-affiliated homicides (which involve gang members but do not resultfrom gang activity), gang-motivated homicides (which result from gangactivity), and nongang youth homicides in St. Louis. We find importantdifferences as well as similarities in the time trends and eventcharacteristic of the two types of gang homicide; in key respects thegang-affiliated homicides more closely resemble the nongang events. Thegang-motivated events exhibit a somewhat distinctive spatial patterning,as might be expected from their connection to turf conflicts. However, allthree homicide types are highly concentrated in racially isolated,disadvantaged neighborhoods, which remain the fundamental socialfacilitators of both gang and nongang violence.     

Pulling levers focused deterrence strategies and the prevention of gun homicide

A number of jurisdictions have been experimenting with new problem-oriented policing frameworks to understand and respond to gun violence among gang-involved offenders. These interventions are based on the “pulling levers” deterrence strategy that focuses criminal justice and social service attention on a small number of chronically offending gang members responsible for the bulk of urban gun violence problems. Unfortunately, there is relatively little rigorous evaluation evidence on the effectiveness of these approaches to violence prevention. In Stockton, California, an interagency task force implemented a pulling levers strategy to prevent gun homicide among gang-involved offenders. A U.S. Department of Justice-sponsored impact evaluation suggests that the pulling levers strategy was associated with a statistically significant decrease in the monthly number of gun homicide incidents in Stockton. A comparative analysis of gun homicide trends in Stockton relative to other midsize California cities also supports a unique program effect associated with the pulling levers intervention.     

Gang Membership,Drug Selling,and Violence in Neighborhood Context

A prominent perspective in the gang literature suggests that gang member involvement in drug selling does not necessarily increase violent behavior. In addition it is unclear from previous research whether neighborhood disadvantage strengthens that relationship. We address these issues by testing hypotheses regarding the confluence of neighborhood disadvantage, gang membership, drug selling, and violent behavior. A three‐level hierarchical model is estimated from the first five waves of the 1997 National Longitudinal Survey of Youth, matched with block‐group characteristics from the 2000 U.S. Census. Results indicate that (1) gang members who sell drugs are significantly more violent than gang members that don’t sell drugs and drug sellers that don’t belong to gangs; (2) drug sellers that don’t belong to gangs and gang members who don’t sell drugs engage in comparable levels of violence; and (3) an increase in neighborhood disadvantaged intensifies the effect of gang membership on violence, especially among gang members that sell drugs.     

COMMUNITIES,STREET GUNS AND HOMICIDE TRAJECTORIES IN CHICAGO, 1980–1995: MERGING METHODS FOR EXAMINING HOMICIDE TRENDS ACROSS SPACE AND TIME*

We merge Exploratory Spatial Data Analysis (ESDA) and a semi‐parametric, group‐based trajectory procedure (TRAJ) to classify communities in Chicago by violence trajectories across space. Total, street gun and other weapon homicide trajectories are identified across 831 census tracts between 1980 and 1995. We find evidence consistent with a weapon substitution effect in violent neighborhoods that are proximate to one another, a defensive diffusion effect of exclusively street gun‐specific homicide increases in neighborhoods bordering the most violent areas, and a spatial decay effect of temporal homicide trends in which the most violent areas are buffered from the least violent by places experiencing mid‐range levels of lethal violence over time. In merging these two methods of data analysis, we provide a more efficient way to describe both spatial and temporal trends and make significant advances in furthering applications of space‐time methodologies.     

The Long Arm of Poverty: Extended and Relational Geographies of Child Victimization and Neighborhood Violence Exposures

Current models of neighborhood effects on victimization predominantly assume that residential neighborhoods function independent of their surroundings. Yet, a surprising proportion of violence occurs outside of victims’ residential neighborhoods. The current study extends on recent advances in spatial dynamics and neighborhood effects to explore the importance of different geographic scales and relational exposures to poverty for child violent victimization. We examine longitudinal data on over 4400 low-income children from high poverty neighborhoods in five cities, who participated in the Moving to Opportunity randomized intervention. The results suggest that surrounding poverty matters for child victimization beyond the effect of residential poverty. Moreover, moving farther from extreme poverty also seems to buffer against victimization and to amplify the benefits of moving to improved extended (residential and surrounding) neighborhoods. All the children in the study, but especially boys older than 10 years of age, seemed to be affected by the long arm of poverty.     

Serious Youth Gun Offenders and the Epidemic of Youth Violence in Boston

Boston, like many other major cities, experienced a sudden increase in youth homicides during the late 1980s and early 1990s. Research evidence suggests that the recent epidemic of urban youth violence was intensely concentrated among criminally active young black males residing in disadvantaged urban neighborhoods rather than all young black males residing in disadvantaged black neighborhoods. Other researchers, however, suggest that there was a diffusion of guns and gun violence from youth involved in street crack markets to youth outside the drug trade who armed themselves primarily for self-protection against the armed criminally active youth. In this paper, criminal history data are analyzed to determine whether the criminal profile of Boston arrested youth gun offenders changed over time and micro-level data on youth gun assault incidents in Boston are examined to unravel whether there were noteworthy changes in the nature of these violent events over time. The results of these analyses suggest that the youth violence epidemic in Boston was highly concentrated among serious youth gun offenders rather than a diffusion of guns away from the street drug trade, gangs, and criminally active youth.     

FACTORS INFLUENCING GUN CARRYING AMONG YOUNG URBAN MALES OVER THE ADOLESCENT‐YOUNG ADULT LIFE COURSE*

This paper uses data from an ongoing panel study of urban youth to examine the causes and correlates of hidden gun carrying among young urban males. The analysis assesses the changing impact of gang membership, drug sales, and peer gun ownership for protection on gun carrying at nine separate points over the early adolescent to young adult life course. In early adolescence, gang membership is a strong motivation for gun carrying. At somewhat older ages, drug dealing, particularly high drug sales, and illegal peer gun ownership replace gang membership as the primary determinants of illegal gun carrying.     

Stranger and acquaintance sexual assault of adult males

This study examined victim and assault characteristics and the nature and extent of coercion, violence, and physical injuries among adult male victims of sexual assaults. Client records of three groups presenting to a sexual assault care center were included: males assaulted by a stranger (n = 64), males assaulted by an acquaintance (n = 81), and females assaulted by an acquaintance (n = 106). Study results revealed that male victims of sexual assault tended to be young, single men who reported high rates of vulnerabilities such as homelessness and physical, psychiatric, and cognitive disabilities. Male stranger assailant victims were more likely to experience assaults involving weapons and physical violence. Injuries sustained by victims and services delivered at the sexual assault care center were similar for both male and female clients. The results of this study reveal new information about violence in male sexual assaults and the vulnerability of the male victims.     

Reducing Homicide through a “Lever‐Pulling” Strategy

The decade of the 1990s witnessed unexpected but welcome large declines in homicide and serious firearms violence. Yet, despite these declines, rates of firearms crime in the United States remain high compared to other western democracies and impose significant costs to society generally and to specific communities particularly. One promising approach to gun crime emerged in Boston during the mid‐1990s. This approach combined face‐to‐face communication of a deterrence message to youth gang members with social service outreach and crackdowns on several gangs. Boston then experienced very significant declines in youth gun crime. This approach was later repeated in Minneapolis with similar promising results. This paper presents the results of a study of a similar gun‐crime‐reduction effort in Indianapolis. Time‐series analyses suggest a significant decline in homicide similar to those observed in Boston and Minneapolis. Comparisons to six similar Midwestern cities revealed that Indianapolis was the only city to experience a significant decline in homicide. The results are discussed in the context of deterrence research and suggest the need to move beyond single‐city evaluations of promising interventions.
