Having read the transcripts from the cell phone, Trayvon, 6'2", 170 lbs notices a short white guy following him. George Zimmerman is 5'7" 160 lbs, sim to Cint Eastwood to Robin Williams. "why are you following me?" is heard. A breathless response,"What are you  doing around here?" Sensible, non hostile answer, "I live here..up at 70.  My dad's girlfriend's place." Oh, Okay, thanks.  Instead, the sound of scuffling, Zim's back wet with grass flecks, smashed nose and bumps on his head.  Not bullying?
