"Stand your ground" doesn't mean 'self-defense' per se, 'stand your ground' refers to whether or not you have a duty to retreat when threatened in an open space, in that jurisdiction. It is separate from self-defense rights 'per se' in that all states recognize a right to self-defense, but states differ on whether you have a duty to retreat. Duty to retreat means, say, if a mugger pulls a knife on you, in a place that you are allowed to be (e.g. city street), if you have a duty to retreat in that jurisdiction, and you were able to run away from the attacker, then you are required to do so and thus not e.g. pull a gun on your attacker to defend yourself. "Stand your ground" laws mean that if you have a right to be in that place, then you don't have a duty to retreat, and thus are allowed to pull a gun on the attacker even if you could have run away.
'Stand your ground' had nothing to do with the George Zimmerman case, and wasn't even brought into the trial. It is inherently irrelevant because you can't voluntarily retreat when someone is on top of you bashing your head into the pavement.

Certainly seems enough for reasonable doubt, especially given that search is the only evidence they have. What a flimsy case. Reminds me of the Shawshank Redemption case.
Nothing to see here. Move along
Your complete lack of empathy suggests to me you might be a sociopath. I don't mean that as an insult, just an honest evaluation.
