Is he telling the truth?

Maybe there's a way to prove that George Zimmerman is a liar. He's the neighborhood watchman who shot and killed a 17-year-old teenager in the city of Sanford. In Florida. Zimmerman claims that the black teenager attacked him and tried to beat him up. And therefore he had to kill the boy in self-defense. On a recording of a 911 call one can hear a skirmish and a cry for help. Sounds a lot like the boy yelling for help. But Zimmerman says he's the guy pleading for help. Now forensic experts have analyzed the recording and they say the voice almost certainly isn't Zimmerman's. Therefore, he may not be telling the truth. It's an interesting case with possible racists overtones. One that a jury may ultimately decide. --Jim Broede
