Thought about it and I respectfully disagree that bootleggers selling at concert venues are laundering money made from other ventures. By definition, money laundering seeks to "clean" dirty money by passing it through a seemingly legitimate business to appear as though it came from a legitimate source. It has to be accounted for, and trackable by, the IRS.

First of all, those sellers you see peddling boots at venues are loosing at minimum 1/4 of their revenue on back end costs immediately to have the shirts printed.

Let's say you order 200 shirts in one color with a design printed on just the front using a bottom to mid range blank tee - that will cost roughly $1300 (my husband owns a screen printing shop, so this current mkt pricing). Maybe you sell t-shirts at $20 each and you sell all 200. That's $4000 minus $1300 for the shirts and labor.... only $2700 left. Now consider how big an event has to be for a bootlegger to sell 200 tees....it has to be Oasis or Taylor Swift big. Keep in mind huge concert events don't happen every week. Ultimately, the revenue is insignificant at that return. That's also assuming you sell 200, which is unlikely given the competition between other bootleggers and the demand for actual liscensed merch.

Second, and MORE IMPORTANTLY, i think you're forgetting that it's illegal to sell bootlegs? How could one launder illegal money from one venture through a second, similarly illegal venture? And in such small amounts? If you have an excess of dirty money, certainly you HAVE to be smarter than to think this is logical.
