Why, yes, Trayvon would have beaten the author to death. After all, the author would have DESERVED it, for dissing young Trayvon in the first place.
This was not “stand your ground”. The fact is, Zimmerman had nowhere to retreat TO, so retreat was absolutely not an option.
Resist an unrelenting attack, or die. Now Trayvon, he had several perfectly good opportunities to retreat himself, but did he take advantage of even one?
Zimmerman only fired his gun because Trayvon saw it and was trying to grab it to kill him with it. He had to choose between killing and being killed.
