I think we have a tragedy of errors here. We have all looked at people who appeared to be acting strange, only to find that they were doing something while talking on a cell phone. It appears that Trayvon Martin was on a cell phone with a hands free device while he was walking in the strange neighborhood.
It would explain a bit why Zimmerman thought he was acting peculiarly.
Id love to know where zimmermans truck was parked. That would tell so much.
The body is a long ways from any intersections were a sign would be.
also the 911 tape the long 14 min one with the hysterical lady.
She says they were behind her house talking.
then there was a fight.
Also most people know how a fight can travel.
It can start over here and end way over there.
And the 911 call with the loudest yelling in it.
Like right before the shot there is a really loud banging. You can here the house shake. That seems like a turning point in the fight to me. When zimmerman has had enough and was going for backup.
Go to Wikipedia and find more on this case.
