Let’s see what we have so far
*eye witness testimony supporting Zimmerman’s version
*911 call made by the eyewitness with Zimmerman heard yelling for help in the back ground
*physical evidence noted by police in their report about Zimmerman’s condition
*subsequent medical check of Zimmerman reported as saying he sustained a broken nose and other head injuries
Those FACTS are strong. Moreover Martin was not shot at a distance but at close range. You have watched too much TV. Those facts alone are enough to no charge.
Did Zimmerman reach for his cell or his gun??? Zimmerman says a phone, so it must be true, right... he wouldn't make up a story to protect himself, would he???? It's his word against a dead man's.
By distance, I mean how close... point blank gun against his chest (as would be the case in a close fight) or maybe a few feet (perhaps Martin got up after the initial beating when he heard someone yelling for 911, in which case perhaps he was getting ready to flee).
Wait for things to be investigated by experts.
