Residents sit on their front porch in the neighbourhood of Goldsboro, once an incorporated all-black city during the segregation era, that has been absorbed by the town of Sanford, Florida April 3, 2012. Sanford is the Florida town where George Zimmerman, 28, a neighbourhood watch volunteer, fatally shot Trayvon Martin, 17, on the night of February 26, saying he had acted in self defence.
