If you think about it you would realize which one was more likely to be screaming.Zimmerman had his nose broken and his head severely lacerated and Martin was shot in the heart.
The prosecution says that since the screaming stopped right after the gun shot, it’s obvious to anyone in their right mind that it was Trayvon screaming. That’s just a dumb enough statement to show the fix is in. I guess that means Trayvon was beating the hell out of Zimmerman while screaming “Help, I’m beatin’ this cracker’s ass! Help!” BAM! “Never mind.”
