I can't believe the screams I heard in that 911 tape were those of an older, heavier man with a gun, as opposed to a 17 yr-old boy armed with Skittles and an iced tea. There may indeed have been a struggle, as Zimmerman seems to have sustained some injuries too. But who wouldn't turn around and fight someone who was pursuing you? I don't blame Trayvon for defending himself against a would be attacker. But unless it can proven beyond measure that it was Zimmerman pleading for help, I will never believe it. Surely, the testimony of Trayvon's girlfriend would prove otherwise.
As the evidence has been presented thus far, I have no sympathy for Zimmerman. To me, he had a pre-conceived idea as to who Trayvon was (as indicated by his comments to the dispatcher heard on the 911 tape) and he acted on those ideas, not on what he actually encountered in the person of Trayvon Martin that night.
I don't trust Fox News. Whoever gave it the name Faux News was a genius.
