Former New York City Mayor Rudy Giuliani on Monday appeared on Fox News to defend his argument that civil rights activists were wasting their time fighting police abuses of power because he said that "black on black" violence was the real problem. During a Sunday discussion about a possible grand jury indictment against the Ferguson police officer who killed unarmed teen Michael Brown, Giuliani had asked Georgetown Professor Michael Eric Dyson why he was not also concerned with "the poor black child that is killed by another black child." “First of all, most black people who commit crimes against other black people go to jail,” Dyson explained.
