At age 16, Robert J. Durán joined a street gang in Ogden.
For many, such a choice means eventually going to prison or dying an early death. But Durán stopped participating in gangs and began studying them and the police and societal response to gangs.
Durán, now an associate professor of criminal justice at New Mexico State University, has written a book that is part memoir and part academic journal. The book from Columbia University Press is called "Gang Life in Two Cities: An Insider's Journey."
