Oscar Pistorius sat through a tough week of emotional testimony in his murder trial. Several witnesses took the stand including the former Olympian's neighbor's who say they heard a woman's screams coming from the house. But Pistorius's lawyers tried to make the case that he mistook his girlfriend Reeva Steenkamp for a burglar, and it was actually Pistorius screaming. Nick Valencia has the latest.

Anderson discussed this with criminal defense attorney Mark Geragos and former federal prosecutor Sunny Hostin who says Pisotrius' defense "is he screams like a girl."
