Some teenagers were playing American football on the street when one of them noticed a body stabbed to death beneath a cab. The victim was a supporter of KKK movement and the cab belongs to an Asian guy who used to borrow his vehicle to the victim to help him make ends meet (they forged a close bond in A.A. meetings, much to Briscoe understanding). Fingerprints inside the cab lead detectives to two well-known writers of crime novels, both addicted to alcohol. They spent together the night drinking booze at a local pub; totally drunk, one of them killed a cabbie after a petty argument and stole some bucks from his wallet. The perp had priors, having spent many years behind bars for selling drugs in his freshman year, and inside the prison he committed a murder in the laundry room in the same way (by stabbing in the chest). McCoy was stunned when the defendant tells him he deserves the death penalty: then it's up to the psychiatric and the judge to determine if he's mentally insane or not.
An original episode: no defendant is willing to go to the death row, but the writer explained he'd rather end up his life than living his life in prison the same way day by day.
