Like, they offered you $1MM (clean) to put $100MM cash in a suitcase and smuggle it through customs? Or to babysit it on a chartered flight and claim it was yours at customs? Because those feel pretty different.
I assumed they were offering him clean cash. Maybe it was a "just help yourself to 1% of the bag". At any rate, the perk of working for money launderers and literally depositing the dirty money is you should be able to do the exact same strategy with your million.
