<p>The San Francisco Chronicle's recent series on domestic violence movingly portrays the tragic murder of Nadine Nunes at the hands of her ex-husband Todd Vernon, who also killed his three children. However, there is no credible evidence to support the series’ principal contention that “men are murdering their partners in increasing numbers.” The only evidence offered is the vague assertion of a local domestic violence advocate. In place of facts and research the series substitutes emotion, ominous references to firearms, and the implication that any normal guy becomes a homicidal maniac the moment he can’t find a job.</p>
