As the death toll rises, residents and police seek solutions to end the proliferation of gangs, drugs and guns.

Jack Levin, a sociology and criminology professor at Boston’s Northeastern University, says it’s troubling that Chicago’s murder count is rising while it falls in other major cities. In 2010, Los Angeles had 297 murders, the lowest since 1967. New York homicides have been declining since 1990, when a record 2,245 fell in the nation’s largest city.

Everyone agrees it must be stopped. But how?
