Peace Officer explores both the militarisation and increasingly violent culture of police forces, as told through the career of William Lawrence, a former sheriff of Davis County in Utah United States, who established and trained the state’s first SWAT team. As a gifted investigator, Lawrence’s savvy skills help break the Ted Bundy case. He also sees SWAT enter the public consciousness and transform the culture of policing throughout the 1970s, along with the convergence of the War on Drugs on policing attitudes and police violence. He eventually leaves public office, concerned, when soon after, his son-in-law is killed in an emergency call gone awry by the very same SWAT unit he created 30 years ago. An internal investigation of course finds no police wrongdoing, so Lawrence turns to his own renowned investigative skills. He sets out to not only uncover the truth of his son-in-law’s homicide, but to tackle the culture and attitudes of modern-day policing on a national level.
