I doubt there will ever be an answer to the question of "who was screaming" that satisfies the "Zimmerman must burn camp", but it stands to reason that the screamer was the guy getting beaten. After all, why would the guy not getting beaten scream for help? The next question to be answered, from the circumstantial evidence, is "who was getting beaten?". From the physical evidence the only rational answer is, Zimmerman, because he is the only one with any injuries. Add to that very reasonable analysis the testimony of the only eye witness (so far) to the actual fight, John Goode, who said, "Zimmerman was on the bottom and Martin was on top, and Martin was punching Zimmerman, and Zimmerman was screaming for help". There really is only one reasonable conclusion: Zimmerman was being beaten and was screaming for help.
The only real question before the jury is this: Did Zimmerman reasonably fear great bodily harm, or death in this scenario? If the answer to that question is yes, then this is a plain vanilla exercise of lawful self defense. The question of murder 2 is preposterous based on the evidence so far.
Having said all of that, I still think it will be a hung jury. This jury is under too much pressure to convict Zimmerman despite the evidence. Those six ladies on the jury still have to live in Seminole county. With Sharpton threatening the sort of civil unrest that he stirred up in Brighton Beach and his Tawana Brawley lies, and with all the other race hustlers getting a piece of the action, I think it is inconceivable that at least one of the jurors won't be intimidated.
Adding to this analysis, look at the commenters here at RIU who refuse to be swayed by the evidence and insist that Zimmerman must be punished. If they are representative of the average jury pool then it wouldn't matter if the jury had a front row seat to the whole incident with instant playback, their answer is going to be "Zimmerman scraped his head on a tree, and he had no right to ask Martin what he was doing in the neighborhood, and he should have taken his beating like a man, and his head was barely scratched, so lock him up!!!"
Of course, the trial is not over yet and the prosecution might have evidence that we have not yet seen that would convince a reasonable person that Zimmerman is a murderer. If that happens, I am willing to change my mind.
