Florida lawmakers will hold hearings this fall on the state's "Stand Your Ground" self-defense law, which has become a lightning rod for criticism following the acquittal of George Zimmerman in the shooting death of unarmed Black teenager Trayvon Martin.

The announcement on Friday by Will Weatherford, the speaker of Florida's House of Representatives, marked the biggest concession yet by the state's Republican leaders to protesters' demands for a top-to-bottom review of the law, which allows people in fear of serious injury to use deadly force to defend themselves rather than retreat.

Since Zimmerman's acquittal on July 13, Martin's grieving parents, backed by African-American civic leaders, celebrities, students and political figures, including President Barack Obama and Attorney General Eric Holder, have all said the Stand Your Ground law needs to be re-examined
