Amanda Knox: I Didn't Do It

Diane Sawyer wasn't skirting the drama Tuesday night as she conducted the first sit-down interview with Amanda Knox since the young woman was tried in Italy for the murder of her roommate. "Did you kill Meredith Kercher?" Sawyer asked. "No," Knox replied. The interview was emotional at times, with Knox tearing up speaking about parents and reliving her her police interrogations, which she says broke her. "What happened to me, hit me like a train, and there was nothing I could to do stop it," she said. "For all intents and purposes I was a murderer, whether I was or not." Of her acquittal's recent overthrow by the Supreme Court of Italy, Knox says: "I can't be afraid right now I have to be ready to fight and defend myself."
