Investigator Dale Gilbreath testified that he does not know whether Martin or Zimmerman threw the first punch and that there is no evidence to disprove Zimmerman’s contention he was walking back to his vehicle when confronted by Martin. The affidavit says “Zimmerman confronted Martin and a struggle ensued.”
But Gilbreath also said Zimmerman’s claim that Martin was slamming his head against the sidewalk just before he shot the teenager was “not consistent with the evidence we found.” He gave no details.
Look for the Obama/Sharpton Presidential race riots of 2012 this summer.

sure seems there was whole lot of evidence the media chose NOT to produce before..
why?
