The author, Lt. Michael P. Keefe, who was named Investigator of the Year by the Minneapolis Police Department in 2006 when he was a homicide detective, reveals how he and Sgt. Paul Burt blew the whistle on corruption inside the department.

They were joined by a small number of other Minneapolis police officers and an FBI agent who put their careers on the line because they, too, refused to turn a blind eye to misdeeds.

The author highlights two detailed complaints about departmental corruption-one that was filed in 2009 and the second in 2016, which was sent to the FBI via Sen. Charles Grassley's office. If either had been duly acted upon, the officer involved shooting of Justine Damond, and the in-custody death of George Floyd, would have likely never happened.
