Yeah. Sure. That's nice. That means a lot. Except the testimony that is NOT presented by the defendent is NEVER heard by the jury. The judge tells the jury not to act on things they did not hear. Since the jury did not hear the defendent nullify the prosecution's evidence, they had to accept the prosecution's evidence without rebuttal. I've served on a 1st degree murder trial. All we had was the prosecution's evidence. The defense never said a word.
If Westerfield testifies that he went on a trip and never saw the girl, the jury will have to act on that. Combine that with the flimsy prosecution evidence and he walks.
