Professor Jens Ludwig of the University of Chicago has been studying gun violence for much of his adult life.  He offers fresh insights into the subject in his new book, Unforgiving Places (University of Chicago Press, 2025). In a wide-ranging conversation, Ludwig argues that we need neighborhoods with “more eyes on the street” to prevent verbal altercationsfrom escalating and multiple programs that teach young people to be less impulsive and more deliberate in situations where pride and anger can easily explode.
