随着射击运动枪支的更新换代,利用淘汰小口径运动枪支进行违法犯罪活动的案件也越来越多。为了更好地对老式运动枪支射击弹壳上所留痕迹进行技术鉴定,我们选用了常见的庆华标准5.6mm手枪、西湖Ⅰ型慢射手枪、健卫一九5.6mm步枪、峨嵋-752型5.6mm标准步枪和三角牌5.6mm长弹进行了射击实验,对上述四种枪支的射击弹壳的留痕部位、痕迹形态、形成机理、鉴定价值等问题逐发进行观察、测量、统计、分析、研究,得出一些结论。 相似文献

丢失枪支不报罪的危害行为是过失导致枪支丢失,而不是丢失枪支后不及时报告;不及时报告与严重后果之间并不具有刑法上的因果关系,它既不是危害行为也不是危害结果,而只是一种限制处罚范围之要素;判断是否“及时报告”应着眼于客观上是否在危害后果发生之前的合理时间内报告,而与行为人何时明知或应知枪支丢失没有关系。 相似文献

Can empirical data generate consensus about how to regulate firearms? If so, under what conditions? Previously, we presented evidence that individuals' cultural worldviews explain their positions on gun control more powerfully than any other fact about them, including their race or gender, the type of community or region of the country they live in, and even their political ideology or party affiliation. On this basis, we inferred that culture is prior to facts in the gun debate: empirical data can be expected to persaude individuals to change their view on gun policies only after those individuals come to see those policies as compatible with their core cultural commitments. We now respond to critics. Canvassing the psychological literature, we identify the mechanisms that systematically induce individuals to conform their factual beliefs about guns to their culturally grounded moral evaluations of them. To illustrate the strength and practical implications of these dynamics, we develop a series of computer simulations, which show why public beliefs about the efficacy of gun control can be expected to remain highly polarized even in the face of compelling empirical evidence. Finally, we show that the contribution culture makes to cognition could potentially be harnessed to generate broad, cross-cultural consensus: if gun policies can be framed in terms that are expressively compatible with diverse cultural worldviews, the motivation to resist compelling empirical evidence will dissipate, and individuals of diverse cultural persuasions can be expected rapidly to converge in their beliefs about what policies are best. Constructing a new, expressively pluralistic idiom of gun control should therefore be the first priority of policy-makers and -analysts interested in promoting the adoption of sound gun policies. 相似文献

Conceptual inconsistencies in routine activities theory are illustrated by demonstrating how gang membership, gun carrying, and employment can be categorized as both risk and protective factors in a high‐poverty context. Two waves of longitudinal data from a high‐poverty sample of African American youth were used to examine the determinants of victimization risk. Bivariate analyses indicated that gang membership, gun carrying, and employment status are significant risk factors for violent victimization, but these effects were mediated by measures of lifestyles (e.g., demographic and family factors, deviant lifestyles) included as controls in the full multivariate model. In other words, the strong positive relationship between gang membership and gun carrying found in previous studies may be due to model misspecification and/or the lack of research on high‐poverty samples of inner city youth from the Deep South. Additional logistic regression analyses also indicate that the number of hours employed per week (but not employment status) is a risk factor for violent victimization. Finally, the theoretical implications of these findings for routine activities theory are discussed. 相似文献

ABSTRACT Recently, states have enacted teacher-carry laws. While controversial, little scholarship has tapped public attitudes toward such reforms. Because public opinion shapes policy, the public is an important stakeholder in this debate. Thus, we investigated three questions. First, how supportive is the public of arming teachers? Second, what demographic and social divides exist, if any, for reform approval? Finally, do crime-related perceptions, concerning views about public safety, and criminogenic influences shape policy preferences? We test these questions using a 2018 poll of Virginia residents (N = 521). Overall, approval for teacher-carry is split. Crime-related perceptions mediate some of the initial social and demographic divides in opinion but other correlates, such as parental status, remain salient predictors of views. Implications are discussed. 相似文献

Public mass shooters are often assumed to be an exceptionally American problem, but little is known about what proportion of global offenders attack in the United States, or how America’s offenders compare to those in other countries. The present study offers the first quantitative analysis of all known offenders from 1966 to 2012 who attacked anywhere on the globe and killed a minimum of four victims. The results suggest that public mass shooters in the United States are significantly more likely to arm themselves with multiple weapons and attack at school and workplace settings, while offenders from other countries are more likely to strike at military sites. These differences may be partially attributable to America’s national gun culture and its particular set of social strains. 相似文献

The "humane killer" or captive-bolt gun, is the tool/weapon widely used in meat industry and private farmer households for slaughtering animal stock. Out of 17,250 autopsies performed at the Institute of Forensic Medicine in Novi Sad during the 15-year period (1991-2005), 29 cases of suicides and two homicides were committed by captive-bolt pistols. Wounds inflicted by captive-bolt guns have specific morphological features, distinctive from wounds made by other kinds of hand firearms. Selected features of the captive-bolt wounds (punched round entrance and a double pattern of smoke soiling) depend on distance and angle of instrument at the time of firing. Autopsy findings were compared with an experimental model consisting of 20 domestic pigs. Obtained results confirmed that the appearance of the entrance hole and soot deposits, along with differences in shape, location, extent, and density of soot blackening, could be useful in identification of weapon, direction of discharge, shooting distance, and angle of the muzzle to the frontal and sagittal planes of the head at the moment of fire. 相似文献
