Amid increasing hardship and limited employment options, poor urban youth are developing creative online strategies to make ends meet. Using such social media platforms as YouTube, Twitter, and Instagram, they're capitalizing on the public's fascination with the ghetto and gang violence. But with what consequences? Ballad of the Bullet follows the Corner Boys, a group of 30 or so young men on Chicago's South Side who have hitched their dreams of success to the creation of "drill music" (slang for "shooting music").

Gang- and drug-related inner-city violence, with its attendant epidemic of incarceration, is the defining crime problem in our country. In some neighborhoods in America, one out of every 200 young black men is shot to death every year, and few initiatives of government and law enforcement have made much difference. But when David Kennedy, a self-taught and then-unknown criminologist, engineered the "Boston Miracle" in the mid-1990s, he pointed the way toward what few had imagined: a solution.

The story of the young sociologist who studied a Chicago crack-dealing gang from the inside captured the world's attention when it was first described in Freakonomics. Gang Leader for a Day is the fascinating full story of how Sudhir Venkatest managed to gain entree into the gang, what he learned, and how his method revolutionized the academic establishment.
