Record contained sufficient evidence to support jury’s guilty verdict on brandishing firearm in furtherance of crime of violence (i.e., Hobbs Act robbery), even though victim of robbery could only testify that she believed defendant had used gun during robbery, because it felt “really hard” and like “metal” when pressed against her back. Record showed that defendant had used gun in another Hobbs Act robbery that took place day after instant charged offense, and jury could reasonably infer that victim’s testimony in instant case pertained to gun used by defendant. Also, Ct. rejected defendant’s claim that offense of attempted Hobbs Act cannot serve as predicate offense for his conviction for brandishing of firearm in furtherance of crime of violence under 18 USC section 924(c), where Ct. found that Hobbs Act robbery is crime of violence, and where jury found that defendant had requisite intent to commit Hobbs Act robbery.
