Author Douglas Blackmon: 'Slavery didn't end 150 years ago'

Author Douglas Blackmon, who wrote “Slavery by Another Name: The Re-Enslavement of Black Americans from the Civil War to World War II,” tells CNN's Don Lemon that black men were enslaved in the U.S. into the 20th century.

The book was awarded a Pulitzer Prize and is the basis of a documentary film that recently aired on PBS.
