He imported them.
OK if you say so. But being the Customs Office would not allow such a transaction as the copyright clearly states it can't sell as first sale in the USA (Wholesale Imports must pass customs) then please explain how he was able to sell enough of them to make over 1 million dollars.
See the problem here is you don't understand the difference between wholesale and retail and what the right of first sale entails.
I've been selling merchandise all over the globe for over 15 years and purchased goods from overseas sources both retail and wholesale. There is a difference and what this kid did was legal. But the copyright holders want their cake and eat it to. If we still had a legal system they would lose BUT its been bought and paid for so we will see.
