Three days after a Florida jury found George Zimmerman not guilty in the shooting death of 17-year-old Trayvon Martin, Chattanooga's NAACP is calling for action.

The call for action, comes at the request of the national organization  who is urging local chapters to sign a petition pushing for a federal investigation.

The local chapter says it's not all about this one case, but flaws in the entire justice system.

"It's pretty obvious that he was racially profiled," said Rev. William Terry Ladd III, NAACP.

Chattanooga's NAACP is joining chapters across the country denouncing the verdict in the George Zimmerman murder trial, and demanding a federal investigation.

"We're past the verdict. Now we have to deal with the next step in the process," said Ladd.

The group wants a federal investigation to determine if Trayvon Martin's civil rights were violated.

Tuesday, US Attorney General Eric Holder promised that investigation is coming to a crowd in Orlando.

"We must stand our ground to ensure that our laws reduce violence and take a hard look at laws that contribute to more violence than they prevent," said Eric Holder, US Attorney General.

NAACP members say it's not just a problem in Florida.

They want state law makers to take a hard look at Tennessee's Stand Your Ground Law, which allows a person to use deadly force if they feel they are in danger.

"Most of us in this movement, and most of us who are black living in these communities recognize this isn't just one isolated event. I think it frustrates us because Trayvon was a 17-year-old kid that looks like a lot of our relatives," said Ash-lee Henderson, Concerned Citizens for Justice.

"People are caught up in whiteness and blackness and brownness and forgetting that they are all united in humanity," said Quinston Coleman, NAACP.

Members are hoping the Zimmerman verdict will be the launching pad into an in depth conversation about racial profiling and violence.

"I don't think the issues are dealing with individuals. I think it's more systemic problems and I think that's what we're trying to do as the NAACP is fight those systemic problems," said Ladd.

Concerned Citizens for Justice rallied outside the federal courthouse in Chattanooga Sunday.

They plan to return this weekend with a peaceful protest to demand the justice department see the investigation through.
