During George Zimmerman's trial for the alleged murder of Trayvon Martin, the media relied mostly on one man for pro-Zimmerman commentary: his friend and fellow neighborhood watch volunteer, Frank Taaffe. It has since come to light that Taaffe is an ex-con and fervent white supremacist who believes that whites and blacks have no business mingling and claims that "the only time a black life is validated is when a white person kills them." He also hosts a white-power podcast. On one episode last fall he argued that all women who married black men would probably meet the same fate as Nicole Brown Simpson. ("I always say, you lie down with dogs you're going to get fleas—especially if they're black dogs.&quot

Nevertheless, the cable news networks have continued to give Taaffe airtime. Most recently, CNN's sister network, HLN, has been tapping him for commentary on the case of Michael Dunn, who, like Zimmerman, stands accused of murdering a black teenager in Florida. In the last few days, Taaffe has appeared on HLN at least six times, and he says on his Facebook page that he's slated to make nightly appearances on two HLN shows, Nancy Grace and Dr. Crew on Call, for the remainder of the week.

Taaffe's task is defending Dunn, who shot 17-year-old Jordan Davis outside of a Jacksonville gas station after arguing with the teen and his friends over loud music. Dunn claims he saw Davis holding what looked like a shotgun and that he fired at the boys in self-defense, but witnesses maintain that Davis was unarmed. On air, Taaffe has argued that the killing was justified, even if Davis wasn't pointing a firearm, because young black men are prone to violence. Here's a snippet from his exchange with an African American guest on Dr. Drew on Call last week:
