Identifying the voice is crucial. Trayvon’s mother has good reason to identify the voice crying for help as her son’s. It makes him him the victim rather than the perpetrator.
It sure is. GZ told the police that he called out for help and at least one witness said that it was him. Under the scrutiny in a court room it is bound to become very clear what the truth is. If Zimmerman was the one crying out for help this whole case will fall apart.
