Considering the defendant in the case had a gun pulled on him, was facing four-to-one odds, and a direct threat was made against him, I would say retreat wasn't an option and Florida's stand-your-ground law was definitely applicable. Good call by the judge. Too bad charges couldn't have been dismissed by the DA prior to going to trial.
Mr. Gallo's attorney, Anthony G. Ryan, stated "I am just glad justice was done in this case and my client was able to return home and be with his family." It sounds like Gallo was in jail the entire time of the trial. I would think that with the circumstances as they were, he would have been given bail.
