"As a matter of principle and matter of law, by law you can't have unarmed person killed, and the law says, well we just couldn't come to terms with it," Sharpton said of the split jury verdict. "This is a national concern. Florida is a big problem -- ground zero for fighting issue of this year the stand your ground law."

McBath and Davis said Wednesday they have drawn support from Trayvon Martin's parents, who went through a similar ordeal after George Zimmerman was found not guilty last year in the shooting death of their 17-year-old son.

"I'm in constant contact with Tracy Martin, Trayvon's father, and I text Sabrina [Trayvon's mother] all the time and I just want to let them know, every time I get justice for Jordan, it's going to be justice for Trayvon, for us," Davis said.

Corey, whose office also came under fire for failing to get a murder conviction against George Zimmerman in Martin's killing, said the race of the victim and the race of the perpetrator doesn't make any difference in prosecution.

"Trayvon, Jordan -- all tragedies -- we need to put focus on all of them, not just certain cases," Corey said. "The focus needs to be on all violence against all races, all ages. It doesn't matter what race is on either side of that gun -- it's all a violation of the law if it's supported by the facts."
