Peace Officer is a documentary about the increasingly militarized state of American police as told through the story of 'Dub' Lawrence, a former sheriff who established and trained his rural state's first SWAT team only to see that same unit kill his son-in-law in a controversial standoff 30 years later. Driven by an obsessed sense of mission, Dub uses his own investigation skills to uncover the truth in this and other recent officer-involved shootings in his community, while tackling larger questions about the changing face of peace officers nationwide. 　　译文(2): 和平官员是一部关于美国警察日益军事化状态的纪录片，这部纪录片通过“ Dub”Lawrence 的故事讲述了这个故事。这位前警长建立并训练了他所在的乡村州的第一支特警队，却在30年后的一场有争议的对峙中看到同一支队伍杀死了他的女婿。在执迷不悟的使命感的驱使下，杜布利用自己的调查技巧，揭开了这起以及最近其他与警察有关的社区枪击案的真相，同时解决了有关全国维和警察面貌变化的更大问题。
