3.5 REASONABLE DOUBT—DEFINED
Proof beyond a reasonable doubt is proof that leaves you firmly convinced the defendant is guilty. It is not required that the government prove guilt beyond all possible doubt.
A reasonable doubt is a doubt based upon reason and common sense and is not based purely on speculation. It may arise from a careful and impartial consideration of all the evidence, or from lack of evidence.
If after a careful and impartial consideration of all the evidence, you are not convinced beyond a reasonable doubt that the defendant is guilty, it is your duty to find the defendant not guilty. On the other hand, if after a careful and impartial consideration of all the evidence, you are convinced beyond a reasonable doubt that the defendant is guilty, it is your duty to find the defendant guilty.
The Ninth Circuit has held that giving the language of this model instruction "did not constitute plain error." United States v. Ruiz,462 F.3d 1082, 1087 (9th Cir.2006) (citing United States v. Nelson, 66 F.3d 1036, 1045 (9th Cir.1995)). In United States v. Gomez, 725 F.3d 1121, 1131 (9th Cir.2013), the Ninth Circuit approved the conditional language in this model instruction regarding a jury’s duty in a criminal case. Nonetheless, "[t]he Constitution does not require that any particular form of words be used in advising the jury of the government’s burden of proof." Id. (citing United States v. Artero, 121 F.3d 1256, 1258 (9th Cir.1997)). In addition, the Ninth Circuit has expressly approved a reasonable doubt instruction that informs the jury that the jury must be "firmly convinced" of the defendant’s guilt. United States v. Velasquez, 980 F.2d 1275, 1278 (9th Cir.1992).
In Victor v. Nebraska, 511 U.S. 1, 5 (1994), the Court held that any reasonable doubt instruction must (1) convey to the jury that it must consider only the evidence, and (2) properly state the government’s burden of proof. See also Gibson v. Ortiz, 387 F.3d 812, 820 (9th Cir.2004), overruled on other grounds by Byrd v. Lewis, 566 F.3d 855 (9th Cir.2009), and United States v. Ramirez, 136 F.3d 1209, 1213-14 (9th Cir.1998).
