This has an interesting parallel in the tradfi world in the City bonds robbery in 1990, where back when bearer bonds were still used a messenger on the street in London was mugged for £290 million worth. Several people wound up dead with more imprisoned and 99% of the bonds were recovered... I'm curious to see the outcome in this case.
It used to be messenger boys would literally carry piles of stock certificates between offices to settle trades. Fairly sure large boxes of cash in the other direction as well.
