The director behind "Fruitvale Station"

Just as the story of Trayvon Martin is resonating with so many people across the county, the 2009 killing of Oscar Grant deeply moved a young film student named Ryan Coogler.  Grant was shot by a transit officer at a train station in Oakland, California. Coogler said it could have been him on that platform, since he was the same age as Grant, and says he wore similar clothes.  Now "Fruitvale Station" Coogler's highly anticipated film, is hitting theaters.  Wolf talked with Coogler.
