I suspect that Florida's self-proclaimed illegal parking monitor would have gotten off too if there hadn't been a store video which revealed this nutjob shot his victim after he'd turned away once he'd been shoved to the ground for harassing the man's wife. The story would have been that his big, strong Black man violently pushed this smaller man to the ground and was going to punch his lights out if he hadn't have taken action the way he did.5'6"- 6'6", it doesn't matter, only that a person reasonably believes that using force is necessary to prevent imminent death. To do that you have to get inside someone's head or believe their story.
We all know about the injuries Zimmerman sustained but we really have no clue what actually transpired that night.
