Police officer John Edwards was patrolling a quiet neighborhood in Bellaire, Texas when he saw an SUV driven by two young African-American men. It was just before 2am on December 31, 2008. Edwards followed the SUV and ran the license plate number. When his computer indicated that the SUV was stolen, Edwards drew his gun and told the two men to get down on the ground. It wasn't until later that he realized he'd typed the wrong license plate number into his computer. He was off by one digit. By the time he realized his mistake, one of the men had already been shot in the chest at close range. But there's a major difference between this shooting case and so many others that we've heard about recently. This is the story of Robbie Tolan.
