The Dutch Christmas Tradition of Black Pete

What do you do when you’re an African-American filmmaker living in a country full of people who dress up in blackface at Christmastime?  You pick up a camera. Roger Ross Williams  talks about his new documentary,  "Blackface." It's about the traditional Dutch celebration of "Black Pete" -- a Santa's helper who dresses in blackface, an Afro wig, red lipstick and big hoop earrings.
