Trayvon Brutally Beat and Broke the Nose of the Neighborhood

[Ry]

i think she assumes it because she saw him right afterwards and asked him what was going on and he ignored her then she asked him again and he said matter of factly to call the police. He didn't have a broken nose or blood etc so she is ASSUMING there wasn't a fight.

Trayvon Martin shooting: It's not George Zimmerman crying for help on 911 recording, 2 experts say:

As the Trayvon Martin controversy splinters into a debate about self-defense, a central question remains: Who was heard crying for help on a 911 call in the moments before the teen was shot?

A leading expert in the field of forensic voice identification sought to answer that question by analyzing the recordings for the Orlando Sentinel.

His result: It was not George Zimmerman who called for help.

Tom Owen, forensic consultant for Owen Forensic Services LLC and chair emeritus for the American Board of Recorded Evidence, used voice identification software to rule out Zimmerman. Another expert contacted by the Sentinel, utilizing different techniques, came to the same conclusion.

Zimmerman claims self-defense in the shooting and told police he was the one screaming for help. But these experts say the evidence tells a different story.

'Scientific certainty'

On a rainy night in late February, a woman called 911 to report someone crying out for help in her gated Sanford community, Retreat at Twin Lakes.

Though several of her neighbors eventually called authorities, she phoned early enough for dispatchers to hear the panicked cries and the gunshot that took Trayvon Martin's life.

George Zimmerman, a Neighborhood Watch volunteer, shot Trayvon, an unarmed 17-year-old, during a one-on-one confrontation Feb. 26.

Before the shot, one of them can be heard screaming for help.

Owen, a court-qualified expert witness and former chief engineer for the New York Public Library's Rodgers and Hammerstein Archives of Recorded Sound, is an authority on biometric voice analysis — a computerized process comparing attributes of voices to determine whether they match.

After the Sentinel contacted Owen, he used software called Easy Voice Biometrics to compare Zimmerman's voice to the 911 call screams.

"I took all of the screams and put those together, and cut out everything else," Owen says.

The software compared that audio to Zimmerman's voice. It returned a 48 percent match. Owen said to reach a positive match with audio of this quality, he'd expect higher than 90 percent.

"As a result of that, you can say with reasonable scientific certainty that it's not Zimmerman," Owen says, stressing that he cannot confirm the voice as Trayvon's, because he didn't have a sample of the teen's voice to compare.

Forensic voice identification is not a new or novel concept; in fact, a recent U.S. Department of Justice committee report notes that federal interest in the technology "has a history of nearly 70 years."

In the post 9-11 world, Owen says, voice identification is "the main biometric tool" used to track international criminals, as well as terrorists.

"These people don't leave fingerprints, but they do still need to talk to one another," he says.

'The home run'

Though the term "biometric analysis" may sound futuristic, it basically just means using personal characteristics for identification. A fingerprint scanner is an example of a biometric device.

Much as the ridges of a human hand produce a fingerprint, each human voice has unique, distinguishable traits, Owen says. "They're all particular to the individual."

Another benefit of modern biometric analysis, Owen said, is it doesn't require an "in context" comparison. In other words, Owen didn't need a sample of Zimmerman screaming in order to compare his voice to the call.

The technology Owen used to analyze the Zimmerman tape has a wide range of applications, including national security and international policing, he said. A recently as January, Owen used the same technology to identify accused murderer Sheila Davalloo in a 911 call made almost a decade ago.

Owen testified that it was Davalloo, accused of stabbing another woman nine times in a condo in Shippan, Conn., who reported the killing to police from a pay phone in November 2002.

Davalloo was convicted, according to news reports.

Owen says the audio from Zimmerman's call is much better quality than the 911 call in the Davalloo case. Voice identification experts judge the quality based on a signal-to-noise ratio; in other words, comparing the usable audio in a clip to the environmental noises that make a match difficult.

And the call on which the screams are heard is better quality than is necessary, Owen says.

"In our world, that's the home run," he says.

Not all experts rely on biometrics. Ed Primeau, a Michigan-based audio engineer and forensics expert, is not a believer in the technology's use in courtroom settings.

He relies instead on audio enhancement and human analysis based on forensic experience. After listening closely to the 911 tape on which the screams are heard, Primeau also has a strong opinion.

"I believe that's Trayvon Martin in the background, without a doubt," Primeau says, stressing that the tone of the voice is a giveaway. "That's a young man screaming."

Zimmerman's call to authorities minutes before the shooting provides a good standard for comparison, Primeau says, because it captures his voice both at rest and in an agitated state.

'CSI' effect

Only one person alive knows exactly what transpired in the moments immediately before Trayvon was fatally shot: Zimmerman, who has claimed he fired in self-defense.

Zimmerman told police he was walking back to his SUV after a brief foot pursuit of Martin, and the teen confronted and attacked him, punching him and slamming his head into the pavement.

Arriving police said Zimmerman was bloodied. One officer wrote in a police report that he overheard Zimmerman telling a paramedic, "I was yelling for someone to help me, but no one would help me."

Angela Corey, the special prosecutor assigned to the case, has yet to decide whether to charge Zimmerman, send the case to a grand jury or decide against charging.

If Zimmerman's self-defense claim is tested at trial, legal experts say a forensic identification of the voice in the 911 audio could be key evidence, either in Zimmerman's favor or to his detriment.

Still, Maine-based audio enhancement expert Arlo West says that today's juries sometimes seem reluctant to accept evidence that's any less conclusive than what they're used to seeing on television.

"I call it the 'CSI' effect," he says, referring to "CSI: Crime Scene Investigation," the popular — if not always realistic — forensics-based TV drama. "You get in front of a jury, and they expect a miracle."

Here is the audio:



It seems that Zimmerman's account is starting to unravel.

An excellent rebuttal as to why this "48%" match may not be all that meaningful.

It isn't really much of a rebuttal as it is only an attempt to cast doubt on the conclusions. However, it seems to focus more on the "ruling in" aspect of the whole science, whereas the claims of the voice experts was only about ruling out Zimmerman.

Injuries or no injuries, when you get into a fight with someone, there is a high possibility that you are going to sustain injuries. If those injuries aren't that serious, then the beating that caused them really wasn't a "life threatening" situation.

Also, if Martin had him totally pinned to the ground while pummeling him and was going for his gun, then how was Zimmerman able to get to his gun first and shoot him? If his hand or hands were free, then why wasn't he fighting back to get Martin off of him? And if Zimmerman's face was being hammered by Martin's fists, how was Zimmerman able to yell for help multiple times so clearly?

Zimmerman's account may be accurate in a lot of the main details, but it seems he isn't telling everything and is lying about a few things.

kid was a piece of shit just like zimmerman. why do they only shows pics of when he was younger. Where are his thugged out pics?

Just because you dress thugged out and post silly pictures on yourself flipping off the camera doesn't mean that you deserve to be shot down in the street like a dog. I'm pretty sure that you have a few pictures that you wouldn't be too proud of as well. Hell we all do.

why do they only shows pics of when he was younger.

Because those were the pictures that the family originally released to the media.

When my father died, our family did not release photos of when he was young and into thug culture, we released pictures of him being a family man, working, and enjoying his different hobbies.

That was how the family chose to portray him and how they wanted him to be remembered. Can you blame them for that? Did you think that his parents had access to his "thugged out" pictures on Twitter or something and that they would want these pictures to be released? Sure the media is biased, but those thugged out pictures are being pushed along by idiots who want to defend Zimmerman for murdering Martin.

Getting your head slammed into the ground isn't a serious situation? Zimmerman (through his brother) says he managed to move his head off the concrete to the grass because he didn't think he could take any more blows to the concrete. I'm sorry, if someone takes multipe blows from the back of the head to concrete, they are liable to have some serious brain damage.

How many times was his face hit by Martin? At least once or twice, we simply don't know the extent to Zimmerman's facial injuries. I don't think it is unreasonable he could have been screaming for help. If he sustained more blows to the back of the head he might not have been able to.

If Martin has Zimmerman pinned to the ground, and he goes from pummeling Zimmerman to go for his gun, that would give Zimmerman an opening to also go for the gun. If Martin kept pummeling Zimmerman he very well might not have had a chance to actually get to his gun and get a shot off and Martin may not have stopped beating him until the cops came.

They interviewed Zimmerman for about 5 hours. There are a lot of things we just don't know.

Well maybe the media should do a little research. The pics of Martin as an older kid have been available for awhile now. There is no need to keep showing this photo of him at 12 year's old. It's intentionally deceptive to rile people up that some 250 pound dude (even though he isn't nearly that big anymore) got in a fight with some 12 year old looking 120 pount weakling. It's a deception, plain and simple.

I don't blame the Martin family for releasing that photo, but I certainly blame the media for going along with it without any research on their part.
