From Theranos to Enron, we can't get enough of corporate scandals. We also can't get enough of the intriguing people who perpetrate them. But instigators of fraud are not all Disneyesque villains chasing money and power at any cost, says DePaul University accounting professor Kelly Richmond Pope. She studies white-collar crime and finds that besides intentional perpetrators, there are also accidental and righteous ones. And she shares real stories of these long-overlooked employees and explains exactly which behaviors and incentives should raise red flags for managers and leaders. Pope is the author of the new book Fool Me Once: Scams, Stories, and Secrets from the Trillion-Dollar Fraud Industry.
