What is the probative value of evidence in a sexual assault case where the victim was threatened by a friend of the accused?

As to the probative value of the evidence, "[a] witness who testifies despite fear of recrimination of any kind by anyone is more credible because of his or her personal stake in the testimony. Just as the fact a witness expects to receive something in exchange for testimony may be considered in evaluating his or her credibility [citation], the fact a witness is testifying despite fear of recrimination is important to fully evaluating his or her credibility. For this purpose, it matters not the source of the threat. It could come from a friend of the defendant, or it could come from a stranger who merely approves of the defendant's conduct or disapproves of the victim. It could come from a person who perceives a social or political agenda to have been advanced by the defendant's actions. It could come from a member of the witness's profession, religion, or subculture, who disapproves of the witness's involvement for some reason. It could come from a zealot of any stripe, large groups of whom seem ready to rally to virtually any cause these days. [] Regardless of its source, the jury would be entitled to evaluate the witness's testimony knowing it was given under such circumstances. And they would be entitled to know not just that the witness was afraid, but also, within the limits of Evidence Code section 352, those facts which would enable them to evaluate the witness's fear."
