You don't really know how it would have turned out.
You don't think that Martin had the right to
stand his ground?
"In the United States of America, stand-your-ground law states that a person may justifiably use force in self-defense when there is reasonable belief of an unlawful threat, without an obligation to retreat first. "
If someone is pursuing me in their vehicle and then leaves vehicle to continue that pursuit, I see that as a REAL THREAT. zimmerman didn't have to leave his vehicle at all to continue his pursuit.
I think with the facts that are present you can't say that GZ did anything unlawful to allow for that law to apply to TM. You can debate the morality of him following and profiling (even with a CCW), but neither of those things are illegal for a private citizen. The unlawful threat would have to be proven in this case that GZ threw the first punch, and there just isn't anyway of knowing that.
If Martin felt threatened by someone following him for no reason and following him after he tried to avoid him, and then left his vehicle to follow him on foot, I can see any reasonable and HONEST person agreeing that he most likely felt pretty threatened.
I walk my dogs @ 4:50am, if some asshole started following me while i am walking my dogs, I would feel like there is some trouble about to happen from that person. My awareness and threat level would be pretty elevated. If i tried to avoid him and he kept on pursuing me, that "threat level" would definitely escalate. If the son of a ***** then got out of his vehicle to pursue me and we came into close quarters, I would DEFINITELY feel the need to be pro-active and defend myself.
