I am not sure what your post even means. Editing seems to be a lost art.
Anyway, what ELSE we "know" is largely found in the realm of the physical.
For example, I have seen the evidence of the injuries to Zimmerman's nose. Haven't you? I have seen evidence of the injuries to the back of Zimmerman's noggin. Haven't you? I have yet to see any evidence of injuries to Trayvon OTHER THAN, of course, the tragic bullet wound. Have you?

You are a funny guy.
Not at all. Well, at least not in this regard.
If there was a fight that caused Zimmerman to feel (reasonably feel) in fear for his life, that fight must have left some evidence behind. And lo and behold, we see Zimmerman's face, he has a broken nose, the back of his head (consistent with his account) has injuries to it. But there are no injuries to the guy Zimmerman said was beating him up (except maybe some knuckle scrapes which actually kind of support Zimmerman's account a bit further).
I cannot say that Trayvon got "no injury" since he died by bullet wound. But that is the thing that ENDED the fight.
The physical evidence supports Zimmerman's account and is consistent with that account.
Such matters as that have actual weight in the minds of jurors who DO try to be fair and reasonable.
