Convicted sex assaulter Bill Cosby wants a judge to toss a defamation lawsuit against him because his accuser is a public figure and not a private person. The statute of limitations prevents criminal charges against Cosby for an alleged sex attack on actress Kathrine McKee in 1974, so Mckee filed the civil suit after Cosby called her a liar when he denied the accusation. Nancy Grace talks about the Cosby case with lawyer Anne Bremner, Cold Case Research Institute director Sheryl McCollum, lawyer Ashley Willcott, psychologist Caryn Stark, and RadarOnline reporter Alexis Tereszcuk.
