Gun Enforcement and Gun Violence Prevention Practices among Local Law Enforcement Agencies: A Research and Policy Brief

Controlling gun crime continues to be a difficult challenge for policymakers and practitioners in the United States. In 2009, there were roughly 11,000 murders with firearms in the United State and another 326,000 non-fatal violent crimes with guns . The prevalence of guns is thought to contribute to particularly high levels of homicide in the United States, where some estimates imply that the total costs of gun violence -- including medical, criminal justice, and other costs -- could be well over $100 billion per year.Yet finding common ground for legislative solutions to this problem is quite difficult, making it especially critical to effectively enforce existing laws and utilize other prevention approaches. Indeed, debates on controlling firearms violence often revolve around whether the nation needs tougher gun laws or better enforcement of laws that already exist. However, these debates are not well informed by systematic information on what law enforcement agencies are doing to reduce gun violence, the success of those efforts, and the factors that facilitate or hinder those efforts. In order to inform debate on these issues and to highlight successful enforcement and prevention strategies to reduce gun violence, the Police Executive Research Forum (PERF) undertook a national study of gun violence prevention efforts by local police in urban jurisdictions. The study's objectives were to: 1) to describe the range, scope, and prevalence of police efforts to reduce gun violence; 2) to assess which practices are most effective, both generally and in combination with different gun laws; and 3) to determine how these efforts can be improved

Police strategies to reduce illegal possession and carrying of firearms: effects on gun crime

Criminal misuse of firearms is among the world’s most serious crime problems. Strategies to reduce gun violence include efforts to restrict the manufacture and sale of firearms, interrupt the illegal supply of guns, deter gun possession, reduce gun carrying in public places, toughen responses to illegal gun use, reduce demand for firearms, promote responsible ownership of guns, and address community conditions that foster gun crime. In this review, we examine research on the effectiveness of selected law enforcement strategies for reducing gun crime and gun violence. This review examines the impacts of police strategies to reduce illegal possession and carrying of firearms on gun crime. Examples include gun detection patrols in high-crime areas, enhanced surveillance of probationers and parolees, weapon reporting hotlines, consent searches, and other similar tactics

Homicide and geographic access to gun dealers in the United States

<p>Abstract</p> <p>Background</p> <p>Firearms are the most commonly used weapon to commit homicide in the U.S. Virtually all firearms enter the public marketplace through a federal firearms licensee (FFL): a store or individual licensed by the federal government to sell firearms. Whether FFLs contribute to gun-related homicide in areas where they are located, in which case FFLs may be a homicide risk factor that can be modified, is not known.</p> <p>Methods</p> <p>Annual county-level data (1993–1999) on gun homicide rates and rates of FFLs per capita were analyzed using negative binomial regression controlling for socio-demographic characteristics. Models were run to evaluate whether the relation between rates of FFLs and rates of gun homicide varied over the study period and across counties according to their level of urbanism (defined by four groupings, as below). Also, rates of FFLs were compared against FS/S – which is the proportion of suicides committed by firearm and is thought to be a good proxy for firearm availability in a region – to help evaluate how well the FFL variable is serving as a way to proxy firearm availability in each of the county types of interest.</p> <p>Results</p> <p>In major cities, gun homicide rates were higher where FFLs were more prevalent (rate ratio [RR] = 1.70, 95% CI 1.03–2.81). This association increased (p < 0.01) from 1993 (RR = 1.69) to 1999 (RR = 12.72), due likely to federal reforms that eliminated low-volume dealers, making FFL prevalence a more accurate exposure measure over time. No association was found in small towns. In other cities and in suburbs, gun homicide rates were significantly lower where FFLs were more prevalent, with associations that did not change over the years of the study period. FFL prevalence was correlated strongly (positively) with FS/S in major cities only, suggesting that the findings for how FFL prevalence relates to gun homicide may be valid for the findings pertaining to major cities but not to counties of other types.</p> <p>Conclusion</p> <p>Modification of FFLs through federal, state, and local regulation may be a feasible intervention to reduce gun homicide in major cities.</p

Police Crackdowns on Illegal Gun Carrying: A Systematic Review of their Impact on Gun Crime

Abstract. This paper presents a systematic review of the impact of police strategies to reduce illegal possession and carrying of firearms on gun crime, including directed patrols, monitoring of probationers and parolees, weapon reporting hotlines, and others. Four studies met the inclusion criteria, reporting a total of seven nonrandomized tests of directed patrols focused on gun carrying in three American cities (five tests) and two Colombian cities (two tests). Six of the seven tests (not all of which were independent) suggest that directed patrols reduced gun crime in high-crime places at high-risk times. However, conclusions and generalizations must be qualified based on the small number of studies, variability in study design and analytic strategy across the studies, preintervention differences between intervention and comparison areas, and limited data regarding factors such as implementation, crime displacement, and long-term impact
