The Supreme Court decision to deny Robert Pickton a new trial means the pig-farmer murderer, at least officially, earns an unremarkable position as just another run-of-the-mill serial killer. Pickton was convicted of six counts of second-degree murder. Other Canadian serial killers have murdered more. Of course, Pickton was originally charged with slaying 27 women, and at least 65 women disappeared from a poor Vancouver neighbourhood where Pickton hunted victims. But history will show, officially, that he killed half a dozen.
