Good point! The baggage is never just what’s in the suitcase (or just the cash, as it were), and (to be serious) glad the other person saw that too. The unimaginable degree of shit that they would be accepting if they took it would be mind boggling.
My guess is that because the other party is not the type of person who would have sex for even a suitcase of cash with them, is why the perp wanted them so much they tried a suitcase of cash.
