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.
In March 1964, a 35-year-old African American woman named Johnnie Mae Chappell was walking along the side of the road in Jacksonville, Florida. At the same time, four white men were driving around listening to the race riots on the radio. They had a gun on the dashboard. As they passed Chappell, one of the men leaned out the car window and shot her. As the police investigated her death, evidence began to mysteriously disappear, making it impossible to punish the men who admitted to committing the crime.
In June 2014, authorities released information about a massive child pornography ring being conducted in North Carolina. Four suspects had already been arrested, and the police were asking the public for help finding a fifth suspect. But they didn't need to look very hard - the suspect was about to turn himself in, almost by accident.
