Laws have been enacted to keep firearms out of the hands of abusers. In this study, we examined one such effort-removal of a firearm at the scene of intimate partner violence (IPV)-to assess the subsequent occurrence and number of IPV incidents responded to by police and subsequent risk of injury to the victim. Using the 28,977 IPV calls in one large U.S. city to which officers responded during the 2013 calendar year, we identified 220 first-time incidents in which offenders used (i.e., brandished, pistol whipped, shot) a pistol, revolver, rifle, or shotgun. Officers reported removing a firearm from 52 (24%) of the offenders. After using full propensity score matching to control for potential confounders, logistic and Poisson regressions were used to assess differences between those from whom a firearm was removed and those whose firearm was not removed. Firearm removal at the scene of an IPV incident appears to increase the likelihood of subsequent IPV reports to police and suggestive evidence that subsequent injury to the victim might increase as well. The offender shifting from threats with a firearm to physical violence and a change (an increase as well as a decrease) in victim willingness to summon police may account for the findings.
法律已经颁布，以防止滥用枪支。在这项研究中，我们研究了这样一种努力——在亲密伴侣暴力（IPV）现场收缴枪支——以评估随后警察对 IPV 事件的反应次数和数量，以及受害者受伤的风险。使用美国一个大城市在 2013 年全年对警察做出响应的 28977 次 IPV 电话呼叫，我们确定了 220 起首次犯罪事件，其中罪犯使用（即挥舞、用手枪抽打、开枪）手枪、左轮手枪、步枪或猎枪。警察报告从 52 名（24%）罪犯手中收缴了枪支。在使用完全倾向评分匹配来控制潜在混杂因素后，使用逻辑回归和泊松回归来评估从收缴枪支的罪犯和未收缴枪支的罪犯之间的差异。在 IPV 事件现场收缴枪支似乎增加了随后向警察报告 IPV 的可能性，并提供了一些证据表明，受害者随后受伤的可能性也会增加。罪犯从用枪威胁转向身体暴力，以及受害者愿意报警的意愿发生变化（增加和减少），可能是造成这一结果的原因。
