Marc Lamont Hill, the far-left hip-hop professor and paid Fox News Channel analyst, has a record in support of cop-killers. And now we have learned that he went on "The O'Reilly Factor" to defend black militants who held a March vigil in honor of Lovelle Mixon, a suspected rapist with a lengthy criminal record, who murdered four Oakland police officers. Hill said on Fox News that the activists, many of them from a communist organization, were protesting "police terrorism."
