In less than a year, Big Law has seen at least three lateral hires go seriously—even criminally—awry.

There was the case of former Arent Fox partner Robert Schulman, who was indicted last August and convicted in March on charges that he passed on an insider trading tip to an investment adviser. Schulman had moved to Arent Fox in 2015 from Hunton & Williams, about two years after his name came up in a U.S. Securities and Exchange Commission case related to the insider trading allegations.
