Abstract Domestic violence remains a serious public problem, especially in Hispanic communities, where one in three women are victims of domestic violence in their lifetimes. Yet $<$50$\%$ of victims report the incidents, often because of concerns over police officers asking about their immigration status of the status of their family members. We assess the extent to which the implementation of sanctuary policies, which limit the cooperation of local law enforcement with federal immigration authorities, affect domestic homicide rates—a crime rarely unreported. We find that sanctuary policies reduce domestic homicides with a Hispanic female victim, especially in counties with more female officers. In contrast, the effect is smaller in magnitude in counties with mandatory arrest laws for domestic violence already in place. Overall, the results are suggestive of the protective role of sanctuary policies in Hispanic communities.

庇护政策可以减少家庭暴力吗？

摘要 家庭暴力仍然是一个严重的公共问题，特别是在西班牙裔社区，三分之一的女性在其一生中成为家庭暴力的受害者。然而，$<$50$\%$ 的受害者报告了这些事件，通常是因为担心警察会询问他们的移民身份和家人的身份。我们评估了限制地方执法部门与联邦移民当局合作的庇护政策的实施对国内凶杀率的影响程度——这种犯罪很少未被报道。我们发现庇护政策减少了西班牙裔女性受害者的家庭凶杀案，尤其是在女性官员较多的县。相比之下，在已经制定了针对家庭暴力的强制逮捕法的县，这种影响的幅度较小。
