CHAPTER ONE Psychopathy and Its Relevance to Crime and Justice I would have liked him at some point in the process to take responsibility, to show remorse. . . . We didn’t get any of that tonight. —Bob Meyers, brother of Dean Meyers, one of 10 victims of the 2002 DC sniper shootings committed by John Allen Muhammad and Lee Boyd Malvo, after witnessing Muhammad’s execution (“D.C. Sniper John Allen Muhammad Executed,” 2009) Psychopathy is one of the best-validated clinical constructs in the realm of psychopathology, and arguably the single most important clinical construct in the criminal justice system. —Robert D. Hare (1998, p. 189) In 1993, Richard Allen Davis kidnapped 12-year-old Polly Klaas from a slum- ber party at her home in California. Polly had been playing a game with friends while her mother and sister were sleeping in a room down the hall when Davis abducted her at knifepoint. Her body was found two months later 25 miles from her home after Davis, arrested for drunk driving, confessed to her murder when his fingerprints were identified as those of the kidnapper. At the time of Polly Klaas’s murder, Davis was on parole after serving 8 years on a 16-year sentence for a prior kidnapping. On August 5, 1996, a jury deci ded that Richard Allen Davis should be executed. Following the guilty verdict, Davis turned to the courtroom audience and TV cameras, and with a glaring smirk, gestured with his middle fingers without a flicker of remorse. Later, Polly’s father, Marc Klaas, said in a television interview that he hoped the verdict would send a message to “all of the other psychopaths out there” (King 5 News, 1996, August 5). Davis now sits on San Quentin’s death row seeking pen pals through his personal website.1 1 Davis’s website is provided through the Canadian Coalition against the Death Penalty and has gener- ated much controversy.
