Why would each of a dozen punches leave evidence.? Its a strawman that you built while conveniently overlooking the fact that even the SFD found Georges statements consistent with his injuries.
They said it was marginally consistent, and they eventually charged him so I'd say the SPD's (not SFD?) opinion on the matter is somewhat at odds with yours.
So again - whats your evidence that Zimmerman's testimony is untrue?
Injuries not consistent with the beating GZ says he was subject to. Inconsistencies in what he was doing, how he ended up running into Martin, in how the fight started, what happened during the fight, all which seem aimed at portraying Martin as the sole aggressor and George as completely minding-my-own-business innocent. Only minute specs of blood on Martin (including hands) and on George's clothes. Calls for help that end instantaneously with the gunshot.
Any one of the above would be enough for me to think that George is being less than truthful about the encounter. What possible need would he have to lie about events of the evening unless he was trying to cover something up.
Now - I think it's possible that George introduced the inconsistencies out of concern for 'looking' guilty if, for example, he admitted to following Martin in his car, or if he admitted that he spent a couple of minutes walking around looking to see where Martin went. But if he's going to insist on a story that is bordering on impossible, I'm going to assume the falsehoods are on purpose.
We don't know what the witnesses particularly witness #6 will say under the questions poised by the defense. We just have his unshakable observation the Treyvon was totally in control despite a grueling 45 minute adverserial, grilling by the SPD. We have one witness who once again gave an immediate statement with full confidence that the other witnesses would back him up- George Zimmerman.
'Grueling, grilling, adversial' interview with the SPD? I find it funny that you feel the need to include various exaggerated adjectives to describe a routine witness interview - I guess you need to do so to try and bolster your case or something. Please point out which parts of the interview where the witness was 'grilled' or otherwise faced 'adversial' detectives.
While you're at it, please point out where in his 'grueling, 45-minute interview' the witness claims that Martin was 'totally in control'.
'Cause what I hear him say is that he couldn't tell who was yelling. I hear him say he just initially assumed it was the guy on the bottom, but that he couldn't tell, in part because it was so dark - he actually stresses several times how dark it was. I hear him say all he could see is that they were in an altercation on the ground. I hear him say he couldn't hear any other sounds other than 'help'. I hear him say the guys were 'wrestling'. I hear him say 'they're struggling' and he can't see what's going on.
