Exactly what the locals and the parents knew for a month after this happened. Then, word of this got passed through channels to political bigwigs and the entire story changed.
...you post any reliable link that proves that your supposition that Martin sucker punched Zimmerman.
It is in Zimmerman's statement to police at the scene. There seems to be no contradictory 'evidence'. Even the 'witness' (Trayvon's girl friend) said the phone was dropped in mid sentence.
Again, what do you think caused Martin to beat on Zimmerman?
I would be careful about using the GF's statements about what she heard -- she has Zimmerman still following Martin which kind of kills the "he was going back to his truck" stuff.
I can think of a number of reasons why Martin might have "beat on" Zimmerman, but the one that springs to mind first is that Zimmerman was a strange adult male who got out of his car to follow him. If Zimmerman showed or reached for the gun then Martin would have been fighting the strange adult man with a gun who was following him.
Maybe that happened and maybe it didn't. The thing is that I'm not swearing that it did, whereas you and a bunch of others are swearing that Martin jumped Zimmerman without provocation. I say prove it.
