DVC your credibility as an attorney gets lower and lower with each post where you try to inject your seemingly biased opinions.
As an attorney who has supposedly dealt defending something similar to this, you should know that this case has an overwhelming amount of evidence compared to most cases.
We have the shooter, the weapon, (edit: 4) credible witnesses who saw the same thing, numerous 911 calls with recordings that back eyewitness accounts, fresh wounds on zimmerman that match all accounts, the body of the supposed attacker, lie detector tests, numerous recorded testimony the night of the attack..
I mean seriously... The only thing you could ask for is an HD 3d movie of the attack itself.
Now, there might not be evidence that supports your predetermined conclusion, but that wouldn't be a very ethical thing to present to all of us, would it?
Calling the evidence in this case "overwhelming" reflects a fairly remarkable suspension of disbelief on your part. You have knitted together scraps of hearsay, seemingly murky and/or inconsistent eye/earwitness statements, and your own supposition into a unified front of exculpatory evidence, when in reality it is totally unclear to the public (including both of us) whether the totality of the evidence supports such a conclusion.
I did not say I believed Mr. Zimmerman is guilty of murder - I said I thought a hypothetical person could reasonably conclude that he should be held responsible for Mr. Martin's death based on his actions the night of the shooting, because he had ample opportunity to simply stay in his car and mind his own business, and instead he got into a physical altercation that led to the death of an unarmed young man.
I think your comments about what is "ethical" are silly and self-serving. It is true the law has to presume people are innocent until proven guilty, but that does not prevent individual citizens from "ethically" concluding otherwise based on their own interpretation of the evidence - I imagine, for example, you yourself believe OJ Simpson is guilty of double murder, despite the court's conclusion to the contrary.
There appears to be meaningful inculpatory evidence here which you have chosen to ignore as "unethical," but that just demonstrates your own bias. Certainly if one can "ethically" consider a "voice test"/lie detector which would be inadmissible in any court in the United States, it's not unethical to consider the voice analysis experts (who have been permitted to testify on many occasions in courts across the country) who have staked their reputation on the conclusion that the screaming voice is not Mr. Zimmerman's, for example.
Ultimately, it seems to me that in order to decide whether this was reasonable self-defense, a neutral fact finder would have to make his judgment based on whether he believes Mr. Zimmerman's account. The rest of the evidence is equivocal regarding who instigated the fight between Mr. Martin and Mr. Zimmerman. The prosecutors and court may well decide that the evidence is simply insufficient to prove that he was not acting in self-defense, and thus refrain from taking him to trial, but again, that doesn't mean it would be per se unreasonable for someone else to conclude otherwise.
