UJI 14-5020. Credibility of witnesses.

You alone are the judges of the credibility of the witnesses and the weight to be given to the testimony of each of them. In determining the credit to be given any witness, you should take into account the witness’s truthfulness or untruthfulness, ability and opportunity to observe, memory, manner while testifying, any interest, bias or prejudice the witness may have and the reasonableness of the witness’s testimony, considered in the light of all the evidence in the case.
