The case has also brought a focus, and criticism, on Florida's "Stand Your Ground" law, which allows a person to use deadly force when threatened without attempting to retreat.

Asked about the law Friday, former Florida Gov. Jeb Bush said, according to FOX News Channel, "I think it's always good to review laws.

"In this particular case based on my limited knowledge, it appears to me that this law does not apply to this circumstance. Stand your ground means stand your ground, it doesn't mean chase after somebody who has turned their back."

He added, "With the grand jury investigation, the Justice Department investigation taking place, the fact that the police chief has stepped aside, the process is in place now and we will get the facts shortly."
