Are innocent people being executed? Are death penalty cases being investigated and tried as if someone's life depended on it? Is capital punishment justice or revenge? Retired LAPD detective and bestselling author Mark Fuhrman seeks to answer these questions by investigating the death penalty in Oklahoma -- a place where a "hang 'em high" attitude of cowboy justice resulted in twenty-one executions in 2001, more than in any other state in the nation. The majority of these death penalty cases came from one jurisdiction, Oklahoma County, where legendary district attorney Bob Macy bragged about sending more people to death row than any other prosecutor, and where police chemist Joyce Gilchrist was eventually fired for mismanaging the crime lab. Examining police records, trial transcripts, and appellate decisions, and conducting hundreds of interviews, Fuhrman focuses his considerable investigative skills on more than a dozen of the most controversial Oklahoma death penalty cases, including two in which innocent men nearly lost their lives.
