Objectives
The current review has two aims: (1) to synthesize the impact of unexpected events on trust in police across different contexts and types of events, and (2) to evaluate the methodological characteristics of each study with attention to the assumptions for causal inference.
Methods
We conducted a pre-registered narrative systematic review on 12 independent studies.
Results
Studies closely adhering to causal inference assumption checks (i.e., excludability and ignorability) find significant changes in trust in police following incidents of police (non) violence and protest. Still, excludability is assessed and addressed less rigorously than ignorability in the included studies.
Conclusion
Regarding the procedural justice framework, this provides some causal evidence that vicarious (positive and negative) experiences can shape short-term assessments of public trust in police. We furthermore highlight issues related to design and power, statistical conclusion validity, and the evaluation of assumptions to detect threats to internal validity.

调查设计过程中的意外事件和对警察的信任：系统回顾
目标
当前的审查有两个目的：（1）综合不同背景和事件类型的突发事件对警察信任的影响；（2）评估每项研究的方法特征，同时注意因果推断的假设。
方法
我们对 12 项独立研究进行了预先注册的叙述性系统评价。
结果
严格遵守因果推理假设检查（即排他性和可忽略性）的研究发现，在警察（非）暴力和抗议事件发生后，人们对警察的信任发生了重大变化。尽管如此，在纳入的研究中，排他性的评估和处理不如可忽略性严格。
结论
关于程序正义框架，这提供了一些因果证据，表明替代（积极和消极）经历可以影响公众对警察信任的短期评估。我们还强调与设计和功效、统计结论有效性以及假设评估以检测内部有效性威胁相关的问题。
