Does the trial judge have any authority to exclude guns and ammunition from the jury?

"Notwithstanding the relevance of the guns and the ammunition, the trial judge would have been justified in excluding them if he decided that their probative value was outweighed by their tendency to confuse the issues or inflame the jury. He might well have done so in this case, in view of the overwhelming evidence that the defendants were the robbers, the rather small addition which the guns provided, and the undoubted effect on the jury of seeing all this hardware on the table. However, the trial judge has wide discretion in this area, see United States v. Montalvo, supra, 2 Cir., 271 F.2d 922, at 927, and we do not find that it was abused here." 421 F.2d at 1204-05.
