“It’s persuasive but would have been more so if he’d have shown ONE mule traveling to multiple drop boxes.”
I haven’t seen it yet, but heard a couple interviews that stated that at least one mule traveled among several counties, to multiple boxes, in one night. Maybe it wasn’t mentioned verbatim in the film. I don’t know.
It was mentioned, but the footage/evidence of that wasn’t actually shown. And that would have been more persuasive if it had been.
