Federal Reports on Police Killings is a collection of the complete reports from the Department of Justice's landmark investigations of police violence in three major American cities. Rather than frame the collection with an introduction, the book will open with the brief DOJ statement about the decision to close the investigation into the death of Trayvon Martin in 2012 - an event that animated the Black Lives Matter movement and can be interpreted as a catalyst for the DOJ's inquiries into law enforcement. The reports that follow speak for themselves.
