It's been surprisingly quiet and empty outside the Sanford court house. That is ominous, in a way.
Listening yet again to the 911 call recording with a person screaming for help, then sudden silence. Whether it is Martin or Zimmerman screaming is still not establish-able. Honestly, now I hope it was Zimmerman. When you stalk a person in the rainy dark and act and speak aggressively while doing it, and your gun holster top becomes visible to your stalking victim as you and he get closer in a yelling confrontation? Yeah....what choice would an unarmed person have but to go on defense/attack? If it's Zimmerman screaming, good. At least Martin tried his best to disable the gunman stalking him. That is what Zimmerman was to Martin - a clear, continuing threat to his safety.
The defense says why didn't Martin run away, that he had time to do so. You don't turn your back on an armed and aggressive-acting stranger. Oh, but he could have just continued walking home. It was just Martin and his younger cousin back at the apartment. Dad and his GF were not at home. Would you allow a threatening, armed person to follow you home when you have a young family member there by themselves? Probably not, if you are a young male with some size and strength. You would feel responsible for that relative's safety, too.
