One fish, two fish, red fish, short fish?
John L. Yates is a commercial fisherman. In 2007, he was hauling in some red grouper when a fisheries officer boarded his ship to inspect his haul. After measuring the fish and finding that some of them were less than the minimum size of 20 inches, he issued Yates a citation and set aside the short fish for inspection at the docks.
Yates had his crew toss the short fish overboard and replace them with other fish. He was later convicted for violating an evidence destruction provision of the the Sarbanes-Oxley Act banking reform statute, passed in the wake of the Enron scandal. He's appealing that conviction to the U.S. Supreme Court, arguing that the vague statute has no place in the Gulf of Mexico.
