In the boss’s lair we find what the flop housers would call a ‘classic evidence dungeon’, a room of full incrimination, the inverse of the 5 amendment.
This basement contains money stacked as high as drugs, with a fully stocked armoury next door to boot.
Economics suggests that if you have drugs or guns (investments) , your cash supply would be decreased at least until you had sold these drugs. This keeping your inventory in constant flux. The perfect equilibrium of these crated stacks points to a zealous need to show us the baddie’s industry.
