The Court reviews a district court's ruling on whether to exclude evidence due to a danger of unfair prejudice for an abuse of discretion. State v. Belanus, 2010 MT 204, ¶ 15, 357 Mont. 463, 240 P.3d 1021. A district court abuses its discretion if it acts arbitrarily or exceeds the bounds of reason resulting in substantial injustice. State v. Doyle, 2007 MT 125, ¶ 43, 337 Mont. 308, 160 P.3d 515.
