Participants will wear hoodies on the square
A rally will be held at Fountain Square today to commemorate the shooting death of Florida teenager Trayvon Martin and to demand a thorough investigation of the incident.The event begins at 5 p.m. and attendees are asked to bring signs that aren’t posted on sticks, to comply with a local law, and also to wear hooded jackets. Martin, 17, was wearing a “hoodie” when George Zimmerman allegedly killed him Feb. 26 in Sanford, Fla.Rallies have been held across the nation during the past week to protest the handling of Martin’s case. Many of the participants have worn hoodies in a show of solidarity with the slain teenager, often carrying signs that state, “I am Trayvon Martin.”Cincinnati Mayor Mark Mallory posted a similar photograph on his Facebook page over the weekend. It’s unclear if Mallory plans to attend today’s rally.Among the groups organizing the rally are Occupy The Hood and the Intercommunity Justice and Peace Center.Zimmerman, 28, who says he belongs to a neighborhood watch program in his gated community, began following Martin at about 7 p.m. for what he described in a 911 call as “suspicious behavior.” Martin was walking back to his father’s condominium after buying iced tea for himself and Skittles for his soon-to-be stepbrother."This guy looks like he's up to no good, on drugs or something," Zimmerman told a 911 dispatcher.Some sort of encounter occurred that resulted in Martin’s death. Sanford Police didn’t arrest Zimmerman, saying that it appeared he acted in self-defense.Sanford Police accepted Zimmerman’s version of events at face value. “Until we can establish probable cause to dispute that, we don't have the grounds to arrest him,” Sanford Police Chief Billy Lee told ABC News earlier this month.After the incident became publicized through Facebook, Twitter and other social media, public outcry grew. More than 2 million people have signed an online petition demanding justice, and the FBI and the U.S. Justice Department have launched investigations.
