Does all the evidence bolster Zimmerman's claim of self defense?

A great deal of evidence has been released in the Trayvon Martin case.  Several weeks ago the case seemed very different, before the stories, the pictures of the injuries, the witnesses accounts, all of which seems to bolster Zimmerman’s claims of self defense.  But does it?

 

Kendall Coffey was asked that very question on MSNBC.  Author of Spinning the Law, he’s an expert at trying cases in the court of public opinion.  But Coffey doesn’t think that the public reaction will change much, although it could affect the case all the same.

 

“This does more good for Zimmerman than it does for the prosecution because it tells us there are very important unanswered questions,” he explains.  “Enough unanswered questions mean unproven facts and... those are the tools of a defense lawyer trying to establish a reasonable doubt.”
