Opening statements and testimony began in the trial against Duane Davis, charged with the 1996 murder of rap icon Tupac Shakur. While prosectors acknowledge Davis was not the actual gunman, they claim he was the mastermind behind the murder and supplied the gun used to kill Shakur. The defense showed jurors a large slide with a single word on it: “Bullshit” and said their client was known for embellishing and lying about things. And that’s important, because it’s the only way for the defense to refute the prosecution’s evidence, which is Davis’ own repeated statements, confessions and written words about what happened that night on the Vegas Strip.
