"Stand Your Ground" Protesters March on State Capitol
Martin's family was joined by family members of Marissa Alexander, who is facing 20 years in prison for firing a warning shot at her husband who had previously beaten her.
Also in attendance was the Rev. Al Sharpton.
Before the march began, Sharpton called Florida "ground zero" for the fight against the stand your ground law.
Protesters marched as they carried signs that read "Standing Our Ground." Others wore shirts that read, "We are not a threat," while still others carried signs with pictures of Martin on them.
Also in attendance was the mother 17-year-old Jordan Davis, who was shot and killed by Michael Dunn. Dunn claimed he had gotten into an argument with teens in a car who had been playing their music too loud. Dunn -- who is white -- opened fire into the car, killing Davis, who was black.
Last week, a jury in Jacksonville convicted Dunn of attempted murder but not murder.
Before the march, Davis' mother, Lucia McBath, addressed the crowd, saying, "I'm here to accuse the state of Florida and 25 other states of creating legislation that is nothing more than permission to kill."
Trayvon's mother, Sybrina Fulton, also addressed the crowd.
"Florida is failing our young men and women," she said. "Florida has to change this law now!"
