Matthew Horace was an officer at the federal, state, and local level for 28 years working in every state in the country. Yet it was after seven years of service when Horace found himself face-down on the ground with a gun pointed at his head by a white fellow officer, that he fully understood the racism seething within America's police departments. Using gut-wrenching reportage, on-the-ground research, and personal accounts garnered by interviews with police and government officials around the country, Horace presents an insider's examination of police tactics, which he concludes is an "archaic system" built on "toxic brotherhood." Horace dissects some of the nation's most highly publicized police shootings and communities highlighted in the Black Lives Matter movement and beyond to explain how these systems and tactics have had detrimental outcomes to the people they serve. Horace provides fresh analysis on communities experiencing the high killing and imprisonment rates due to racist policing such as Ferguson, New Orleans, Baltimore, and Chicago from a law enforcement point of view and uncovers what has sown the seeds of violence.
