IANAL, however.  But I think when you say

the core question remains unanswered, i.e., whether or not a rational person can reasonably conclude that Zimmerman's life was actually endangered by Martin when he fired the fatal shot that killed him.

...that you are not getting "the whole enchillada."  The core is more complex that that.  

I do agree that GZ seems to have exhibited prejudice against the youth from the start.  Is that the same as profiling?  IANAL.  Is it the same as racism?  I don't think so.  But if he WERE indeed a racist at heart, it might be a contributing factor to his actions later on after he determined the kid was black, would it not?

 but I'm not so sure about this part:

O'Mara would like that -- he wants to be in exclusive control of information released about his client.

Are you suggesting that this release of a quasi-favorable photo was somehow a case of his client acting without his approval or consultation?  Because if so, that's a lot more significant to the upcoming case than the potential contents of the photo itself.   George Zimmerman has shown himself to be a client that is prone to doing things before he consults his lawyer - from the first, speaking to police without the benefit of counsel, to his hijinks with his self-made website and the funds he controlled and spent without telling his lawyer or the court, and his family's actions in speaking to the press and writing letters to the NAACP, if those are indeed genuine.  

It's equally important that Zimmerman's family be coordinating their actions through counsel, too.  These people may feel they are acting in George's best interest, but if they are acting without the benefit of counsel they run the risk of losing another lawyer, i'd say.

Instead I would guess that O'Mara considered the relative benefits of releasing this photo on his defense website vs releasing it through CNN and NeJame and that the action was co-ordinated through the "team" as it were.  

Has the photo since appeared on the defense site?  And if so, does it do so as a scan of the original, or is it an embedded link, video or screen shot of the photo's appearance on CNN, thus giving it legitimacy of a sort?  

As to what led to him getting the photo he says when he first heard about the case he presumed Zimmerman shot Trayvon "in part based on bigotry and racial profiling" because of media reports, , but "as I started getting into a role as an analyst and such, I started asking questions

And, of course, the 7-9 year old wasn't doing something so overtly suspicious like, uh, "looking at houses" while talking on the cell phone to his girlfriend (imagine that: staring at a house while talking on a phone in a dense condo development - such aberrant deviousness!), or acting like he was vaguely "up to no good", whatever that means.

Eg: He didn't say, hey there's this black guy wandering where he shouldn't be. You know. Slam dunk racism.

Zimmerman said that Trayvon Martin was looking AT houses, not IN them.

He was not on his self-appointed "patrols."

I will restrain myself from stating what I think of people who have to take a gun everywhere, even on errands.  But look what happens.

Where I'm from dropping a dime on somebody and surveilling them on such baseless "suspicion" is intending to do them harm...victimizing them.  Not to mention packing heat in the process.  It's no way to treat a fellow human being.  And I say that living in a neighborhood that has break-ins too, including my own crib.

"We are disappointed that the bond was set so low", said Rev. Jackson.  "Tomorrow Mr. Zimmerman's freedom will be restored.  This decision cheapens black life. Justice should serve as a deterrent.  The U.S. Department of Justice and the FBI must play a critical role in this matter because this is a Civil Rights case.  Racial profiling and killings have become a national pattern."

Look, I don't have sympathy, I have to toe the line around here more than anyone.  Its not like I agree with 6.4879% of the "centrist" economic policies around here, but I only really bash you because of your love for A) the Gators, B) the Yankees, C) Real Madrid.

She is interested that they be given the benefit of the doubt.
She is interested that they receive every opportunity to defend themselves.

Jeralyn appears to be refuting the narrative that Zimmerman gunned down a black kid for no reason other than the kid is black.

I did before I commented.
