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.     

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.     

Challenge of Firearms Control in a Free Society

Chapter 10 of The Challenge of Crime in a Free Society, titled “Control of Firearms,” is a brief but strong statement in support of regulating gun transactions, possession, and carrying, with several specific recommendations, including the adoption of universal gun registration and permit‐to‐purchase requirements. The U.S. President's Commission on Law Enforcement and Administration of Justice, when writing the chapter, had no systematic research to draw on. Since its publication in 1967, the field of gun violence has become an active area of research, and much has been learned. But the nation has become far more polarized politically during the last 50 years, and gun policy has become a rigidly partisan issue. A new commission would have great difficulty reaching consensus, although there may be common ground on regulating guns vis‐à‐vis mental illness and domestic violence.     

The National Context of Wicked Problems: Comparing Policies on Gun Violence in the US,Canada, and Australia

Scholars and practitioners have always been dogged by problems that are so complex that no practical solution appears to be possible. These have been referred to in the academic literature as “wicked” problems. However, it is possible that a problem’s “wickedness” depends in part on its context and on the vantage point of the observer, meaning that at least some aspects of wickedness can be thought of as being relative rather than absolute. In this article, the complex policy problem of gun control is examined across multiple national contexts to show how a problem that is perceived as being wicked in one jurisdiction can be seen as manageable in another.

DOES GUN PREVALENCE AFFECT TEEN GUN CARRYING AFTER ALL?*

Previous research suggests that American adolescents usually have ready access to guns, and that the extent of misuse of guns by adolescents is not much affected by local gun prevalence or regulation. This “futility” claim is based on one interpretation of survey data from several cities, but has not been tested directly. Here we do so using microdata from a nationally representative survey, the 1995 National Survey of Adolescent Males. Using the restricted geo‐coded version of these data, and conditioning on an extensive set of covariates, we find (among other results) that the likelihood of gun carrying increases markedly with the prevalence of gun ownership in the given community. We also analyze the propensity to carry other types of weapons, finding that it is unrelated to the local prevalence of gun ownership. The prevalence of youths carrying both guns and other weapons is positively related to the local rate of youth violence (as measured by the robbery rate), confirmatory evidence that weapons carrying by youths is motivated in part by self‐protection.
