Why is it so hard for Chicago police to stem gang-related violence? A lack of leadership … in the gangs. From the Chicago Tribune: “Street gangs, once compared with Fortune 500 companies for their organizational skills and ruthless pursuit of profits, are now mostly made up of small, leaderless sets of members bound together by personal relationships rather than geographic or narcotics-trade ties. Personal insults and petty conflicts, often inflamed by social media posts, are just as likely to lead to a shooting as is competition for drug turf. Taken together, these changes have created an anything-goes atmosphere on the streets.”
