TALLAHASSEE (CBSMiami/AP) – The parents of Trayvon Martin and Jordan Davis are scheduled to testify Monday before a legislative committee considering changes to the state’s so-called “stand your ground” law.

In the morning, the families of Martin and Jordan Davis joined a group of several hundred demonstrators, headed by civil rights activist Al Sharpton, in a protest rally on the streets of Tallahassee against the “stand your ground” law which they said gives someone a license to get away with murder.

George Zimmerman was acquitted in the death of 17-year-old Martin.

Michael Dunn was found guilty of second-degree attempted murder after shooting into a car full of teenagers, killing 17-year old Jordan Davis, in Jacksonville.  There was no verdict on the first-degree murder charge.

Those who attended the rally said both Zimmerman and Dunn got away with murder in large part because of Florida’s stand your ground law.  They want to make sure it doesn’t happen to another family.

In 2005, Florida was the first of 26 states to pass a “stand your ground” law.

Republican Senator David Simmons is still backing the law, but is proposing some changes.  One tweak to the law would be that if you are the person that provoked the force, you are not entitled to stand your ground.
