The politics of hoodie wearing

A bit quiet here about witness accounts
that state Martin was sitting on Zimmerman's chest beating him;
the screaming for help was Zimmerman. Anybody?

I agree re "voice experts." I don't think you can tell definitively whose voice it was via recordings.
Especially since the stress of the situation could've made either man's voice quite different.
I'll bring back articles.

especially considering he picked the fight.

then he compounded it by murdering the kid...

I can show exactly what you can, dave.

squat...

A closer look at the witness statements and audio testimony taken in the immediate aftermath Trayvon Martin's death provides the first insight into George Zimmerman's behavior after he shot the unarmed teen.
A man listed as witness 13 was one of the first people to approach Zimmerman minutes after the shooting. He saw him bleeding from the back of the head and nose. Zimmerman asked the unidentified man to call his wife for him.
"Let her know what's happening, been involved in a shooting and will be held for questioning," the witness told the Florida Department of Law Enforcement. "He was more like, talking like he was having a hard time, looked like he just got his butt whipped ... not like he was in shock, not like, 'I can't believe I just shot someone,' but like, 'Just tell my wife I just shot someone,' like it was nothing."
A woman identified as witness 5 walked out of her home after hearing the altercation to find Zimmerman standing over Martin's body. She said she asked him what was going on and he curtly said just, "Call the police."
The woman told police that Zimmerman, 28, examined Martin's body as he slowly paced back and forth when the police arrived. She watched as they checked the teen's body and turned him over, eventually starting CPR. But he was already dead for five or 10 minutes, she said.
"I do honestly feel that he intended for this kid to die," witness 5 told investigators. "If you're in self defense, shoot him in the leg. He's a 17-year-old, scrawny little kid. You get into a physical fight with him. ... I think the kid was running for help."

Zimmerman would not need to demonstrate that his life was in danger in order to gain protection under Florida law. According to the state's “stand your ground” statute, a defendant doesn't need to be at risk of death, but rather at risk of “death or great bodily harm.” The legislature has not defined "great bodily harm," and Florida courts have said only that it “does not include mere bruises as are likely to be inflicted in a simple assault and battery.”

Me thinks that the state is going to end up laughed out of court if Zimmerman is stout enough to resist their efforts to get him to plead out.....

"If you're in self defense, shoot him in the leg. He's a 17-year-old, scrawny little kid. You get into a physical fight with him. ... I think the kid was running for help."

For a thoughtful, even-handed person, I think you've made several unsupportable leaps without evidence concerning this case, primarily that he was "simply losing a fist fight." We can't know that.

Can you link to those witness accounts?

I've seen articles about "voice experts" who have testified that it was not Zimmerman calling for help, but I have not seen anything about a witness who can report who was calling for help.

(I have my doubts that they can actually determine anything from a recording of a cell phone, but I'm not a "voice expert.")

Zimmerman claims Trayvon went for his gun. I'm still one who believes the whole thing could've been avoided if Zim had listened to dispatch; however, the news, if it bears out, should temper hot opinions.
