dissenting.
There are of course no “circumstances of this case” that justify the majority’s finding. That is why the government did not support the enhancement. In fact, the circumstances demonstrate that a reasonable person would not have been in fear for his life. As the majority appears to recognize, there is no per se rule mandating an enhancement whenever a note is presented stating that the robber is armed. The district judge appears to believe otherwise, or so the transcript shows. That belief is erroneous. I would vacate the sentence and remand for resentencing without the enhancement.
