Other than the beating on Zimmerman part that was witnessed by others.
Are you really that behind the curve on this story?
My statement was with regard to his possibly being a trespasser. He was not and had every legal right to be where he was.
His “beating on Zimmerman” may or may not have been a crime. This is yet to be determined. It is possible, though not particularly likely IMO, that Zimmerman attacked Martin, who was merely defending himself.
The problem here is that the witnesses, for obvious reasons, looked out their windows only when the hollering started. The question of which party was the aggressor is determined by what happened in the seconds between when they confronted each other verbally and when the screaming started. And we have no evidence on that, and are unlikely to have any, except Z’s testimony, since Martin, the other witness, isn’t around anymore.
Did Trayvon commit a crime that night? Quite possibly he committed an assault, or aggravated assault, on George. It is also possible he was defending himself against attack. There is no law that the person defending himself is required to be on the bottom.
