Ta-Nehisi Coates explores America's racial divide in new book
The author says he is terrified by the number of unarmed black men who have died at the hands of police. His new book, "Between the World and Me," is written as a letter to his 14-year-old son on what it means to be black in America. Coates joins "CBS This Morning" to discuss the tough advice he gives to his son and the country.
