Moones Mellouli made a lot of mistakes. On April 4, 2010, Mellouli—a native of Tunisia and a lawful permanent resident living in Kansas—got into his car drunk and with a suspended license, and he hit the road. Then he got caught by a cop and hauled into jail. While locking up Mellouli, the police found four orange tablets in his sock. Mellouli quickly admitted the pills were Adderall, a controlled substance for which he had no prescription. Ultimately, Mellouli pleaded guilty to a very minor charge: possessing drug paraphernalia in violation of Kansas law.
