This is a long (45 minute), but good, interview from Democracy Now with Pulitzer Prize-winning author, poet and activist Alice Walker about the root causes of the Trayvon Martin killing. Worth a listen:

Walker observes that “We are a very sick country. And our racism is a manifestation of our illness and the ways that we don’t delve into our own wrecks. … As a country, we are a wreck.” Powerful words.
