Currently 25 states have "Stand Your Ground Laws" in effect similar to the one in Florida which is drawing close scrutiny.
It is the shooting death of 17-year-old Trayvon Martin allegedly at the hands of George Zimmerman which has spawned this highly charged debate over "Stand Your Ground" in Florida.

"I have been up and down as if I have been on a roller coaster, but I know, beyond a shadow of a doubt that justice will be served," Fulton said.
