TALLAHASSEE, Fla. - Tracy Martin - father of slain teenager Trayvon Martin - was in the capitol to continue his fight against Florida's "stand your ground" law.

Martin, state Rep. Alan Williams, D-Tallahasee, state attorney Willie Meggs, public defender Nancy Daniels and others took part in a Florida A&M panel on Thursday called "Stand Your Ground Law: Where Do We Go From Here?"

Martin called for a repeal, while others suggested changes in the language of "stand your ground." Williams has backed the repeal, but also supports tweaks to the current legislation.

A senate committee recently approved proposed changes that would require the Florida Department of Law Enforcement to develop training guidelines for neighborhood watch groups that, among other things, address unlawful use of force and conduct that could create or escalate a confrontation.

Florida's "Stand Your Ground" law has been in the books since 2005.
