The Us & Them team has tracked the case of James Means - a 15-year-old boy who William Pulliam shot and killed in Charleston, W.Va., in November 2016. The case got national attention partly because Pulliam is white and Means was black. It was one of a number of shootings that focused on questions about racial injustice in our legal system. Last month, Pulliam agreed to plead guilty to second-degree murder. A week later, he wrote to the judge and asked to revoke his plea. Last week the judge called Pulliam into court to get a clarification.
