What is the jury's duty to be impartial?

Further, the jury was instructed not to "let bias, sympathy, prejudice or public opinion influence [its] decision," and to "follow the law as [the court] explain[s] it to you, even if you disagree with it." The jury was instructed on the presumption of innocence, the prosecution's burden of proof, and again on its duty to impartially weigh the evidence. When instructing on witness credibility, the jury was told "[y]ou must judge the testimony of each witness by the same standards, setting aside any bias or prejudice you may have." In short, the court repeatedly impressed upon the jury its duty to be impartial and it is not reasonable to assume the jury allowed the prosecutor's appeals to override that duty. "We presume that jurors treat the court's instructions as a statement of the law by a judge, and the prosecutor's comments as words spoken by an advocate in an attempt to persuade." (People v. Dalton (2019) 7 Cal.5th 166, 260.)
