Leo: You're a courier. You work for him.
Riggs: I'm the drug dealer.
Leo: Right. I deposit the cash into the account of a dummy finance company. Now. Then I issue you a cashier's check in his name... [points to Riggs] minus a small commission for myself.
Murtaugh: How much?
Leo: Two percent standard.
Murtaugh: Not bad, Leo. Pretty prosperous.
Leo: So, you give it back to me as collateral on a loan that I make to you. But you don't pay back the loan. You keep the money.
Murtaugh: How's that work?
Leo: How's what? That's it! Don't you get it? It's your money. You don't pay it back. It's yours, and it's clean. It is now laundered. You cops aren't too bright, are you? Okay, okay-okay-okay. This is the best part. You got it? You take a tax deduction... on interest payments that you don't even make. Am I an innovator? Am I a genius?
Riggs: You're a swindler.
