The Badge Between Us is a raw, unfiltered account of policing that tracks the impact of secondary trauma and moral injury, infused by instances of organizational betrayal and police officer corruption. It is a first-person account of author Terrence P. Dwyer’s final year as a New York State Police Investigator, with flashbacks from a 22-year career spent responding to and investigating violent crime and organized criminal gangs, and its impact upon him and his family. Through the lens of a final gang investigation and the subsequent quintuple murder of a young family, Dwyer delves into the workaday world of a homicide investigator.
