DeKalb NAACP President John Evans (from left), state NAACP President Edward Dubose and WAOK radio host Derrick Boazman share podium recently at a rally outside the Georgia Capitol for Trayvon Martin. Martin was shot dead by self-appointed neighborhood watch patroller George Zimmerman, who has yet to be arrested. The family, meanwhile, has repeatedly asked for a full investigation of the shooting. As part of an event calling for justice for Martin on the one-month anniversary of his death, Trayvon’s parents, Sybrina Fulton and Tracy Martin, marched in Sanford, Fla., with more than 1 million signatures from their Change.org petition calling for the prosecution of Zimmerman.
