On the afternoon of Sept. 26, 2008, Charles Daum made his final pitch to the jury, spinning a narrative that blamed his client’s brother for a cache of drugs.

Daum, a fixture in Washington’s criminal defense bar for three decades, trumpeted several images to the jurors, including one picture where Jerome White, the brother of defendant Delante White, appeared to be bagging up rock cocaine. “Ladies and gentlemen, what you see in the picture is the drug dealer,” Daum declared in U.S. District Court for the District of Columbia. “It’s a candid shot that was never intended to find its way into a federal courthouse.”
