He's as believable as some of the witnesses. Here's two who claim they saw Zimmerman straddling the dead young man who was lying on his stomach. The only problem is, Trayvon was shot in the chest and not the back.

Zimmerman is as believable as all the other witnesses? When he's an, uhm, interested party? You're making me laugh, so tell us why. Here's and interesting bit from the report you linked:

Lamilla and Cutcher described Zimmerman pacing around the body, following the shooting, and disputed that there was any indication of a fight.

'Here's two who claim they saw Zimmerman straddling the dead young man who was lying on his stomach'

The police report validates that claim. The police report states that Mr. Martin was lying face down, with his hands underneath is body.

There are no witnesses who saw Zimmerman straddling Martin while Martin was alive. The irresponsible Anderson Cooper interview of the two non-witnesses began with this question: “What was the first thing you saw?”

The answer was “I heard a shot and ran to the window...”

I’ve heard enough. By their own words, they saw nothing leading up to the shooting. By their own words, they are not witnesses.

Yet it was billed as “witnesses say it was not self-defense!”

Sickening. And utterly irresponsible of Cooper to even air it.
