(Almost) everyone has a price. Show a suitcase containing $5 mil to a border agent making $90k a year, and he'll let you pass 10 tons of cocaine...and maybe even ask his wife to sleep with you (if you request it). Humans and all...
That would be a terrible mistake (beyond the current crime). Once you've allowed the one shipment, you'll possibly be forced to allow or commit much more, under threat of exposure.
