This case stems from a shooting incident in November 2023 at the Tulsa Trip gas station. Marco Atkins, after arriving in a vehicle with his mother and others, encountered Terry Brown, a former rival gang member. Security footage captured the events, showing Brown exiting a store, walking past Atkins' vehicle, and then being shot in the torso by Atkins. Atkins was indicted on multiple counts, including assault with a dangerous weapon, carrying a firearm during a crime of violence, and witness tampering. During the trial, Atkins asserted a self-defense theory, claiming Brown had pulled a gun first. However, the evidence was conflicting: Brown denied pulling a gun, and two other witnesses testified that Brown was not acting threateningly, while Atkins' sister corroborated his account. The central issue on appeal concerned the testimony of a government agent, Ben Nechiporenko, who was questioned about his review of the security camera footage and whether it changed his opinion on whether Brown was armed.
The Tenth Circuit addressed Atkins' claim that the district court erred by failing to sua sponte exclude the government agent's testimony regarding the security footage. Atkins argued this testimony violated Federal Rule of Evidence 701(b) because it was lay opinion testimony that was unhelpful and effectively told the jury he was guilty. The court applied the plain error standard because Atkins did not object to the testimony at trial. Under this standard, reversal requires a showing of error, plainness, and that the error affected the defendant's substantial rights. The court assumed without deciding that the testimony might have violated Rule 701(b), but focused on the third prong: whether the error affected Atkins' substantial rights. The court explained that substantial rights are affected only if there is a reasonable probability that, but for the error, the result of the proceeding would have been different. The court found no such probability here. The evidence of guilt was substantial, including Atkins' admission to shooting Brown, the conflicting testimony regarding whether Brown pulled a gun, and evidence that Atkins discussed self-defense with his mother and admitted it would not work. Furthermore, the agent never explicitly testified that Atkins was guilty or that charges should be pursued despite evidence of self-defense; he merely answered questions about his observations. The court noted the jury deliberated for less than four hours, suggesting the evidence was clear. Consequently, the court held that the agent's testimony did not tip the scales in the government's favor.
The decision affirms Atkins' 180-month prison sentence and five years of supervised release. It reinforces the principle that even if a district court admits evidence in violation of the Federal Rules of Evidence, an appellate court will not reverse if the error is harmless due to overwhelming evidence of guilt. The ruling clarifies that for lay opinion testimony to be reversible error under Rule 701(b), the defendant must demonstrate a reasonable probability that the outcome would have differed without the testimony. No remand instructions were issued as the conviction stands.
