Adopting school resource officers (SROs) is a popular response to school shootings. Using the advocacy coalition and multiple streams frameworks, we explore how school districts in one county formed a coalition with the Sheriff’s Department, adopting SROs in elementary schools following the Sandy Hook shooting. We describe how this coalition was bound together by shared beliefs on school safety and the goodness of law enforcement. The implementation activities of SROs related to the beliefs of the coalition, focusing on security and relationship building. The beliefs were not uniformly understood by SROs—many interpreted their role to include student discipline and managing behavior of students with disabilities. The findings show the utility of comparing policy adoption processes with implementation activities.

对学校枪击事件的普遍反应是采用学校资源官员（SRO）。使用倡导联盟和多流框架，我们探索了一个县的学区如何与警长部门组成联盟，并在桑迪·胡克枪击事件发生后在小学采用SRO。我们描述了这种联盟是如何通过对学校安全和执法善良的共同信念而捆绑在一起的。SRO的实施活动与联盟的信念有关，着重于安全和关系建立。SRO并未统一理解这些信念，许多人将其角色解释为包括学生纪律和管理残疾学生的行为。调查结果显示了将政策采用过程与实施活动进行比较的实用性。
