Heading: cumulative trial errors

Text: 15 Karterman argues that even if none of the alleged trial errors, standing alone, requires reversal of his conviction, the cumulative effect of the alleged errors does. We disagree. If the district court erred by admitting the drug-related evidence, that error was harmless, and the court did not commit plain error by refusing to give Karterman's requested credibility instruction. Because each error is, at best, marginal, we cannot conclude that their cumulative effect was so prejudicial to Karterman that reversal is warranted. See United States v. Necoechea, 986 F.2d 1273, 1282-83 (9th Cir.1993); United States v. Payne, 944 F.2d 1458, 1477 (9th Cir.1991), cert. denied, 503 U.S. 975, 112 S.Ct. 1598, 118 L.Ed.2d 313 (1992). 16
