This study explores the potential that current efforts to limit access to firearms for individuals with serious mental illness (SMI) have for reducing overall rates of murder by firearm in the United States. Official arrest, court and health records provided data on personal and offense characteristics of 95 individuals with SMI and 423 without, all of whom had been convicted of murder in the State of Indiana between 1990 and 2002. Bivariate analyses examined differences between the two groups and logistic regression models examined the relationship between SMI and offense characteristics. Compared to those without, a relatively small proportion of convicted murderers had a diagnosis indicating SMI. The presence of SMI was associated with reduced likelihood of targeting a stranger and was not associated with having multiple-victims or firearm use. Focusing on access to firearms exclusively by individuals with SMI will have little impact on multiple-victim or firearm-related homicides. 相似文献

We develop three points in this commentary on Rosenfeld and Fornango’s empirical assessment of the NYPD policy of stop, question, and frisk (SQF). First, we draw attention to some of the key patterns uncovered in the analysis, posing questions that we think warrant additional thought. Second, we highlight some potential ambiguities between the underlying logic model of SQF and the empirical models assumed in existing research evaluations that have important implications for the conclusions that one might draw from the available evidence. Finally, we suggest some ways in which the empirical basis for evaluating the efficacy of SQF might be strengthened. 相似文献

Tightening budgets and increased demand for public accountability has placed additional stress on already limited police department resources. Web-based crime mapping provides significant improvement over previous methods of information dissemination, allowing police departments to continue to work quickly and efficiently within these limitations. This modern technology has enabled a more proactive approach to policing, including intelligence led-policing and public facing crime maps. As such, officers are now able to better consider spatial patterns related to historic crime, and determine more informedly where crimes may occur in the future, and allocate their limited resources accordingly. 相似文献

The process of swallowing or inserting illegal packets of drugs for the purpose of evading law enforcement officers carries risks other than criminal charges. It can be fatal. Individuals engaged in such activities are called \"Body Packers\" or \"Mules\". The most frequent cause of the death among body packers is acute drug intoxication due to rupture of the package(s) within the gastrointestinal tract. We present the first documented case of a body packer that died from cocaine intoxication following the rupture of packets of cocaine in Western Pennsylvania. 相似文献

An estimated 500,000-plus people are on parole each year, many with serious co-occurring psychiatric and substance use disorders. Using cross sectional, self-report data this study examined the relationships between parolee time to rearrest, serious mental illnesses, and substance dependency (n = 1,121). Regression analyses indicated that after controlling for demographic and criminal justice variables, parolees with serious psychiatric and substance dependence disorders were rearrested faster than non-dually diagnosed parolees (p < .05). An explanation is that compared with parolees without dual diagnoses, parole violations by dually diagnosed parolees are detected and punished more quickly because of closer parole supervision. 相似文献
