The Walmart bribery scandal is one of the most closely-watched cases of alleged malfeasance by  a global company. It broke into the open  in April, 2012, when  the New York Times published a lengthy investigative piece alleging Walmart bribery in a Mexican subsidiary and a cover-up in its Bentonville, Arkansas, global headquarters. The piece, which won a Pulitzer Prize for reporter David Barstow, raised a host of  personal accountability and corporate governance issues for the company.
