A co-worker who witnessed the shooting said Rainey had knocked on RoopÂ’s door, but received no answer. While Rainey was walking down the drive-way, Roop pulled up in his pickup truck and asked why Rainey was at his house. Rainey explained that he was selling steak and seafood. The witness said Roop then pulled out a black handgun and shot Rainey. As Rainey lay on the ground, Roop fired another bullet into the back of his head.
Roop later told police that he shot Rainey in the head “for effect” and that he had three no trespassing signs on his property. Roop said he feared for his life.
Again, this was not the original intent of Florida lawmakers when they enacted SYG.
One can not engage in ‘pre-emptive’ self-defense.
In Florida SYG was conceived in the context of home invasion, epidemic in the State at the time. To ensure a comprehensive application of the law, ‘castle doctrine’/SYG was expanded to include one’s car (car jacking was also epidemic), at a friend’s, neighbor’s, or family member’s home, at work, or ‘anywhere one has a right or is expected to be.’
However, homeowners and property owners are still expected to exercise common sense and good faith with regard to using deadly force, one is not required to retreat but that does not mean he may go on the offensive or otherwise place himself in danger only to justify a SYG defense.
In the case of the OP incident the proper course of action for the homeowner if he felt threatened would be to remain in his vehicle and drive to a safe location to contact authorities. A charge of second-degree murder is indeed justified.
