The jury ruled it by finding him not guilty. Self defense is an affirmative defense, if they had evidence that he started the altercation, they should have convicted him, and would have convicted him.
All the evidence points to Martin starting the physical confrontation. Again, you lose.
Sorry to burst your bubble, but I still don't lose since you're making that up out of whole cloth. The jury would have ruled exactly as they did had it not been proven who started the altercation, which is in fact, is what actually happened.
As you pointed out, the jury needed evidence that Zimmerman initiated the physical confrontation to convict him and that didn't exist. That doesn't mean it didn't happen that way. All that means is that the only living witness to that event was the defendant. So to claim Zimmerman's actions were or were not justifiable is based on your imagination.
