When Jodi Arias takes the stand again on Tuesday, she may finally tell the courtroom and the world how she killed her ex-boyfriend Travis Alexander. The prosecution says she drove to Travis' home on a mission to murder him, while the defense claims she killed him in self-defense after the last of many vicious attacks.

Are the explicit, often demeaning, text messages Travis sent to Jodi proof that he was abusive? Or are those text messages relatively tame in our modern pornography-filled society? Jane and a panel of experts discuss and predict what will happen next in the Arias trial.
