Record contained sufficient evidence to support defendant's conviction on charge of felon in possession of firearm, where arresting officer testified that he saw defendant point silver handgun at him, and where silver gun was eventually found in roof of gutter in nearby house. While defendant denied possessing handgun and video of encounter did not clearly indicate that defendant possessed handgun, jury was entitled to accept officer's testimony that human eyes can see more details in person than what appeared in video. Moreover, jury was allowed to believe officer's testimony over defendant's denials. Also, Dist. Ct. did not err in adding eight levels to defendant's offense level based on his 2004 Illinois drug conviction, where said offense qualified as "controlled substance" under section 2K2.1(a)(4)(A) of USSG. Ct. rejected defendant's claim that definition of controlled substances offense in section 4B1.2(b) of USSG is coterminous with substances mentioned in Controlled Substances Act.
