Homicide data show that urban killings are rising in clusters, while other areas of the same city grow safer, AP's Sara Burnett and Larry Fenn report: "Slayings in Chicago, St. Louis and Indianapolis are becoming concentrated into small areas where people are dying at a pace not seen in years, if ever. Around them, much of the rest of the city is growing more peaceful."
Why it matters: "The inequality between the two realities deepened in recent years, allowing people in the same metropolis to live in one realm with little sense of the other and creating districts of despair where everyone has seen or had someone close to them shot or killed."
