Forensic Experts Say Screams Were Not Zimmerman's

Hugh Pickens writes "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? Now the Orlando Sentinel reports that Tom Owen, a leading expert in the field of forensic voice identification sought to answer that question by analyzing the recordings. His result: It was not George Zimmerman who called for help. 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. Owen 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,' says Owen. The software compared that audio to Zimmerman's voice and returned a 48 percent match. Owen says to reach a positive match with audio of this quality, he'd expect higher than 90 percent. Owen cannot confirm the voice as Trayvon's, because he didn't have a sample of the teen's voice to compare however 'you can say with reasonable scientific certainty that it's not Zimmerman.'"

    Zimmerman's claim of being badly beaten up before he shot the kid doesn't hold up either: there's some footage taken at the police station the night of his arrest, and he looks totally unharmed. No cuts to the back of the head, no broken nose, nothing. Guy's story has more holes than... eh, I'm on my eighteenth hour without sleep due to a project and can't come up with an apt metaphor, but something with a lot of holes.

      Hmm... "my fox tampa bay" and "bob owens"... two totally trustworthy news sites there. good job.

      When NBC News played the audio of the 911 call George Zimmerman made prior to the confrontation that resulted in the death Travyon Martin, this is what they played:

              Zimmerman: This guy looks like he's up to no good. He looks black.

      That audio helped fan the nation-wide flames of hysteria over the supposed fact that the police had released an obvious racist who had tracked and killed Martin out of racist motives. Many Republicans, such as Jeb Bush, the highly regarded former governor of Florida, and many "conservatives," such as Rich Lowry, the editor of America's flagship "conservative" magazine, believed it.

      But the audio played by NBC, though it seemed like "fact" (because it was an audio, and isn't audio true?) was false.

      Here is the transcript of the actual audio of the 911 call:

              Zimmerman: This guy looks like he's up to no good. Or he's on drugs or something. It's raining and he's just walking around, looking about.

              Dispatcher: OK, and this guy--is he black, white or Hispanic?

              Zimmerman: He looks black.

      That is the slipshod hoodwinking professional reporting we need then?

      Well, Fox did go to court to defend the right to lie in "news" stories. Take anything you read or hear from Fox with a *massive* grain of salt.

    I agree, he shouldn't be facing the court of public opinion. He should be facing the court of law. It certainly doesn't look like that is happening.

    It looks increasingly likely that he will face a jury. And when he does, the jury will likely be informed of Fla. Stats. 776.041, which states:

    776.041âfUse of force by aggressor.â"The justification [of self defense] described in the preceding sections of this chapter is not available to a person who:
    (1)âfIs attempting to commit, committing, or escaping after the commission of, a forcible felony; or
    (2)âfInitially provokes the use of force against himself or herself, unless:
    (a)âfSuch force is so great that the person reasonably believes that he or she is in imminent danger of death or great bodily harm and that he or she has exhausted every reasonable means to escape such danger other than the use of force which is likely to cause death or great bodily harm to the assailant; or
    (b)âfIn good faith, the person withdraws from physical contact with the assailant and indicates clearly to the assailant that he or she desires to withdraw and terminate the use of force, but the assailant continues or resumes the use of force.

    To be brutally honest, I think both his attackers and his defenders sound very silly to me in making bold statements before the facts are in. The prudent thing to do is to simply say that we are not going to condemn him or exonerate him until the process plays out and renders a verdict.

    [ Note, I'm not saying that everyone must accept the results of the process -- just because it's the legal result doesn't mean we have to personally believe it. But there is a difference between disagreeing with the result after it happens and jumping to your own conclusion before it has been conducted. The former seems to me reasonable, the latter not so much. ]

    You do know that there was at least one eyewitness that corroborated that Zimmerman was on the ground being attacked and calling for help?

    You do know there are other eyewitnesses who claimed that was not the case? That's your probable cause right there.

    Fabulous! New information! I'm for new information. Here is a link showing the eye witness I'm referring to:

    In addition, an eyewitness, 13-year-old Austin Brown, told police he saw a man fitting Zimmerman's description lying on the grass moaning and crying for help just seconds before he heard the gunshot that killed Martin.

    And here is another report, which seems consistent with the above, and seems to be someone different:

    After hearing raised voice, the witness said he peered out of the window and saw two men grappling with each other on the ground, one on top of the other. He said there were two struggles, both of which were on the grass next to a sidewalk. “I heard the yell for help then I heard another as I would describe as an excruciating type of yell. It didn’t even sound like a help it just sounded so painful,” he said. Following the cry, he described hearing “popping” sounds, believed to be multiple gunshots. One of the men then cried out for help.

    And of course Zimmerman was treated on the scene for head injuries, which is again consistent with the other reports.

    As it was, the police took Zimmerman in for questioning in handcuffs, and released him. They know where he lives.

    Do you have a link for me?

    Have you read anything about the case?

    Being on the phone does not magically make one safe.

    No, but being on the phone in a vehicle, someone who neither knows nor cares that you exist is not a threat.

    Did Zimmernan at the time?

    Yes, he was carrying a gun; what do you think he shot Trayvon with? He chose to leave the safety of his vehicle to pursue an unarmed teenager while carrying. He then provoked a confrontation by, you know, chasing down an unarmed kid. None of these facts are challenged by Zimmerman or the police. At this point, whether Trayvon threw the first punch isn't terribly important. He had every right to feel threatened if Zimmerman was pursuing him, especially if he noticed the gun, and to defend himself from that threat. You can't just provoke a fight and then invoke self-defense when the person defending themselves from you gets the upper hand.

    Except he wouldn't have broken the law if he believed he was protecting himself. The beauty of the Florida stand your ground law is that it's so broad that had Martin killed Zimmerman he could have plead self defense. Except for the fact that he was black and not the son of a judge. Florida's stand your ground law protects the instigator. That's the point of stand your ground laws. Prior to SYG the standard was that you had to try and avoid or escape situations that require deadly force. Florida's statue is so broad that believing you are preventing a felony is a good enough reason to shoot to kill.
