What about the 911 calls where he is heard screaming for his life? Sounds to me like he was in fear of his life.
Interesting development Cliffey boy:

Two forensic experts told a Florida newspaper the person screaming in the background of a 911 call was not George Zimmerman the night teen Trayvon Martin was shot. According to the Orlando Sentinal , the two leading forensic voice identification experts who listened to a 911 call from a neighbor at the gated community where Martin was shot told the Sentinal that the screams didn't match Zimmerman's voice.

Tom Owen, forensic consultant for Owen Forensic Services LLC and chair emeritus for the American Board of Recorded Evidence, used sophisticated voice match software. Owen said there was only a 48% chance that it was Zimmerman crying for help on the tape and that usually, a positive match rates higher than 90%. "As a result of that, you can say with reasonable scientific certainty that it's not Zimmerman," Owen told the Sentinal.

I even chose the story from a FOX source so you all wouldn't say I was being "partisan".

riiiiight.. you'd say anything to make sure the scary black boy is guilty.
Why? Do you really thing that I would be lining up defending a minority Democrat?

I mean I would, but that totally blows your view of me being racist...

And he isnt guilty, he is dead...

This is the first REAL evidence that contradicts Zimmer's account in any way.

It is pretty weak, though. One of the audio experts enhanced the 911 tape and listened to it and concluded he is listening to the screams from a 17 year old boy and NOT a 28 year old man, i.e. his ears are better than your ears. The other expert "used sophisticated voice match software" and concludes there is a 48% chance that the cries are from Zimmerman. Like I said, pretty weak, but better than inventing conspiracy theories that are idiotic on their face.

It doesn't say it wasn't him.It says its only a 48% of being him.and a usual positive hit is 90%.
I would also bet that the software they used for this is meant for clear speech not yelling from 30 feet away .

They talk about clarity but if Zimmerman's account is true he was lying on his back with the possibility of his breath being knocked out while Travan was sitting on his chest pummeling him in the rain.

I am not sure it is very good evidence.

Could you tell me what the alpha score or n= figure for that 48% please?

Those experts must be retarded, 48% is nearly 50%...which means realistically it could've been either mans voice.

Smoking gun is about as lacking as it was in Iraq.

here we go... somebody misreading statistics...

what the expert is saying is that in order for him to conclusively say that the voice screaming for help was zimmermans, there cannot be more than 10% in error... therefore the match would have to be 90%. the match is only 50%.

he's only saying that he has enough evidence to conclusively RULE OUT zimmerman as the voice heard on the 9-1-1 call.

there is no voice sample from trayvann so it's impossible to run that experiment with his voice.... the 50% doesn't have anything to do with one man or the other....

Yeah, they can half tell us it wasn't Zimmerman...reliable statistics...can you give me the margin of error or alpha score I asked for already tho?

How much do you want to bet that we will soon have other experts claiming the exact opposite?

How much you want to bet the news service contacted 5 or more *experts* and reported on the most sensational one.
If this is the most sensational they have then they don't have much. One expert listens to the screams and says they sound like they are coming from a 17 year old and the other expert says there is a 48% chance that it is Zimmerman screaming for help. I'm pretty sure that is enough to convict Zimmer if the jury is cherry-picked from the RIU politics section, but a jury that is randomly chosen, well, I will say a conviction is not likely based on that when you stack it up against the other facts that we have in hand.

the alpha score, and specifics are trade secrets in the software he used. i tried to find the details and the software costs 4500...

here you can see how it works:
