MIAMI -

Cries of injustice rang loud the day after the not guilty verdict came down in the George Zimmerman trial.

"When do we want it? Now. What do we want? Justice. When do we want it? Now!" the crowd screamed.

Many stood on the steps of the Freedom Tower, remembering Trayvon Martin. The scene, at times, was all too familiar.

The group began their march at the Torch of Friendship in downtown Miami. There, the signs of anger and looks of disappointment were firm.

But the rallying cry was different. Demonstrators used the opportunity to try and move past the verdict.

"I think we have the foundation now to have a real debate in this country with guns and the use of deadly force," said teacher Khris Kirchner. "And I will work to continue that."

"I'm a black youth, and just to see one black youth die, that's crazy. It's like, when is it going to stop? Its been going on for too long," said Keno Walker.

There were renewed calls that the state's "stand your ground law" be changed, and that stricter gun laws be enacted. That is how the group said you keep Martin's memory alive.

"I hope that the case of Trayvon Martin will serve as a story that will show us how scary it is to have weapons available, and have them used and to be comfortable with that idea," said Kayla Malone.

State Senator Dwight Bullard took part in the march. Bullard said despite last year's review of the "stand your ground law," he'd still like it be narrowed or repealed. The senator said the demonstration was more about what happens next.

"This isn't just an Overtown, liberty city or black community," said Bullard. "This is a justice right-wrong issue that has to be embraced."

Another participant said that seeing the diversity in the crowd at the rally says a lot -- it's no longer just about one community or one issue.
