Journalist and author Ta-Nehisi Coates grew up in West Baltimore during the crack epidemic of the 1980s. As a young man, Coates faced the constant risk of violence on a daily basis. He later enrolled at Howard University, where he began to pursue a passion for history and writing. Coates, now a national correspondent for The Atlantic magazine, argues in his latest piece that mass incarceration of African-Americans exacts a devastating financial and psychological cost on black families. Diane talks with recent MacArthur fellow Ta-Nehisi Coates on mass incarceration, his memoir and America’s long struggle with issues of race.
