Callan: 'Good Samaritan' defense could be key in Conrad Murray trial

The trial against Dr. Conrad Murray began yesterday and the defense wasted no time, laying out a theory that singer Michael Jackson – in a desperate attempt to sleep – downed a lethal dose of Propofol. 

The prosecution on the other hand, played a disturbing audio tape for the jury of Michael slurring his words and almsot inaudible. The chilling tape, which is said to be recorded by Conrad Murray, had to be played twice in the courtroom so the jury could try and understand what was being said.

Paul Callan discusses the first day of the trial with American Morning, and how he believes a 'Good Samaritan' argument could be the key to Murray's defense.
