but it can't. So I don't really understand your line of thought.
Maybe you were being more philosophical than I interpreted.
perhaps, but there were many that were, and when you have an avalanche of witnesses I don't think you can deny them having a strong effect on the minds of the jurors.
I was arguing that the proof of who was screaming is of limited value, especially to the defense. Even if it can be established it's value is mainly about the degree of the crime. IF IT COULD be proven that it was Trayvon it would be pretty devastating to the defense and do a lot to establish depraved mind. If it could be proven that it was Zimmerman it might create doubt about the depraved mind but it does nothing to establish that Zimmerman was justified in the use of deadly force.
I don't think the witnesses proved anything. Again, they are at best making an honest guess, could easily be influenced by bias or they are just lying.
