Shootings are no longer fueled by large-scale territory disputes authorized by gang leaders. Instead, the violence is concentrated in areas where young men — confronted by a chronic lack of jobs and opportunity — align in block-to-block cliques. While drug disputes still drive some conflict on the West Side where open-air markets thrive off easy access to the Eisenhower Expressway, much of the violence today is driven by interpersonal conflict and retaliatory shootings, according to the report.
