Kansas City leaders are promising the city's most violent criminals a long hot summer. And it has nothing to do with the weather. A new initiative announced Tuesday afternoon will target those thought to be disproportionally responsible for the majority of violent crime on Kansas City streets. "Kind of like cutting out a tumor," said Kansas City Mayor Sly James. James announced the plan, called the KC No Violence Alliance, or KC NoVA, along with Jackson County Prosecutor Jean Peters Baker and Kansas City Police Chief Darryl Forté at an afternoon press conference. It will become a long-term collaborative effort aimed at the city's urban core, which bears the brunt of violent crime, they said. And beyond the focus on taking the worst criminals off the streets, it also will contain a social service component that will help with things like job training, education and health care for those seeking a way out of the criminal lifestyle. The Kansas City plan is the result of several months of planning and studying similar "focused deterrence" programs in cities like Boston, Indianapolis and Cincinnati that have seen significant decreases in homicides and gun-related crimes.
