i have no proof, but it sounds to me like Zimmerman might have grabbed the kid, the kid fought back and so Z shot him. That’s not self defense. He had a bloody nose, the kid didn’t beat him to a bloody pulp. I could be wrong, but I still think Z ought to be arrested,
Like you said, you have no evidence regarding who attacked who first.
As for the bloody nose, one blow can cause a person to lose consciousness and then be completely defenseless against further mayhem. It happens all of the time. Ghetto thugs knock someone out and then proceed to maim or kill them. There is no reason for Zimmerman to risk this. This whole "it was just a fistfight" line is garbage. If you attack an innocent person then you deserve what you get. I do not know whether Zimmerman was completely innocent, but I have seen no evidence indicating otherwise.
I agree with your analysis.
The teen was unarmed. He was in his father’s community and returning to his home after a trip to buy candy. He could be my son or my grandson.
There is far too much blaming the victim on this thread and excusing the killer.
