In 2010, 66 children died of gunfire in Chicago, and hundreds more were injured. Staggering statistics like this show that gang violence in the Windy City has grown out of control. CeaseFire, a community organization with a public-health approach, tries to lead Chicago's youth away from a life of crime. To do that, the group employs "interrupters," former gang members who actually go to the scene of a conflict and try to resolve it in a non-violent way. And it's all chronicled in a recent documentary film called "The Interrupters."
