Trujillo v. State (2002)
In Trujillo v. State, 44 P.3d 22, P5 (Wyo. 2002), the Court set forth the following broad guidelines found in the Standards for Criminal Justice which are applicable to a prosecutor's arguments to a jury:
(a) The prosecutor may argue all reasonable inferences from evidence in the record. It is unprofessional conduct for the prosecutor intentionally to misstate the evidence or mislead the jury as to the inferences it may draw.
(b) It is unprofessional conduct for the prosecutor to express his or her personal belief or opinion as to the truth or falsity of any testimony or evidence or the guilt of the defendant.
(c) The prosecutor should not use arguments calculated to inflame the passions or prejudices of the jury.
(d) The prosecutor should refrain from argument which would divert the jury from its duty to decide the case on the evidence, by injecting issues broader than the guilt or innocence of the accused under the controlling law, or by making predictions of the consequences of the jury's verdict.
(e) It is the responsibility of the court to ensure that final argument to the jury is kept within proper, accepted bounds.
