For the past several months...I've interviewed top law enforcement officials and crime researchers: Anthony Braga, a professor of criminology at Rutgers University who has just begun a study in Boston to try to find out where illegal guns are coming from and how they are being acquired; David Hemenway, a professor at the Harvard School of Public Health and renowned firearms expert, to learn what a so-called "public health approach" to addressing urban street shootings would look like.

William Julius Wilson, a Harvard professor of social policy whose landmark book, "When Work Disappears: The World of the New Urban Poor," blames the lack of work for much of the dysfunction in inner city neighborhoods.

...With Jack Shonkoff, a pediatrician who directs the Center on the Developing Child, I studied research about how toxic stress interferes with normal brain development in young children, increasing the risk of anti-social behavior later.
