You think GZ stopped screaming for help because the gun was so loud?
It was TM screaming for help because a man was pointing a gun at him.
A bullet to the heart stopped that screaming for help.
He was screaming for help while on top of Zimmerman? How exactly did Zimmerman point the gun at Martin while Martin was on top of him beating his face? I don't know who was screaming for help and I don't think it matters. Physical and eyewitness evidence puts Martin on top of Zimmerman going mma style on Zimmerman's face when the shooting took place. Who is screaming is a distraction that was only brought up so much because it was the only thing the prosecution had to try and get a conviction based on sympathy.
