Now additional information (witness testimony) trickles out, raising more questions. Just more reason why everyone needs to step back and let the PD and DA do their job. The PC crowd and racists have already concluded who is guilty of what crime, without knowing much of anything, and are seeking mob justice. The PD has investigated, we'll see if charges are filed.
One thing that isn't clear to me is, under FL law in a criminal case, is the burden on the prosecution to prove beyond a reasonable doubt that the action was not self defense? Or, is the burden on the defendant to convince a judge/jury that the action was self defense? If it's the former, I don't see any way they could prove beyond a doubt that it wasn't self defense (at least from the evidence I've seen).
To use the analogy of an NFL replay challenge. Lets say on a play a guy comes close to scoring and there's no replay angle that shows conclusively that he did or didn't. Whatever call the ref makes on the field (TD or not) will stand because there's no evidence to overturn it. I see this case as similar. It doesn't appear there's evidence beyond a reasonable doubt to 'overturn' the self defense assertion, though Zimmerman may in fact be guilty.
