Angela Corey is the lead prosecutor in the Trayvon Martin case. She, and she alone, will determine whether there is probable cause to arrest and charge George Zimmerman in the shooting of Trayvon Martin.

For Tracy Martin and Sybrina Fulton its the difference between getting advanced notice of the lotto numbers under the auspices of justice, or looking like they were willingly surrounded by race-baiting self-promoting opportunists.
For George Zimmerman its the difference between another step forward in the judicial process of defending himself, or the first step in putting a shattered life back together, if that is even possible  at this point.
For the media the contrast is between a story based around delayed justice, or based around a rush to judgement.   For the people of Sanford Florida it could be just the beginning of another painful step in the building of a racial powder keg, or perhaps, the beginning of the end.

Either way, according to States Attorney Angela Corey, she will present ‘new information’ in a press conference planned sometime over the next three days:

The special prosecutor, Florida State Attorney Angela Corey, has alerted the media that she “is preparing to release new information” about her investigation within the next 72 hours. Reporters will be alerted three hours before the news conference, which is to be held in either Sanford or Jacksonville.
Corey’s office says in its news release that media access will be limited “because of safety concerns.”

One thing appears consistent in all of the reports, releases, and known evidence.  George Zimmerman believes himself to be innocent of any charges or wrongdoing.
If you think about George Zimmerman’s actions from a legal aspect, he has done everything wrong.  Within 37 minutes of he shooting he waved his right to legal representation and willingly talked to police for over 5 hours.
The following day, still without any representation or legal advice, he willingly took the police back to the scene of the shooting and re-enacted the details of the event step by step on video.
You can well imagine that any misstep in any of these prolonged conversations if there had been a snippet of inconsistency the police would have latched on to him and never let go.  But instead of finding anything they could dig further in to what did the investigators do?    Law enforcement was unable to find, discover, or obtain any evidence that would allow them to press even involuntary manslaughter charges against Zimmerman.
It would appear that at the very least George Zimmerman was entirely consistent with every statement to police and investigators.
A story initially driven by unfounded media accusations directed at the Sanford Police department doing a poor job appear to have been totally false.   Quite the contrary, it appears from all current reports  and analysis the police investigation was actually quite by the book.   So the narrative within the legal parameters has instead evolved into a discussion of the laws within Florida themselves.   Quite a substantive turn around.
Meanwhile there is still a bounty on George Zimmerman’s head.
The police spent weeks gathering even more evidence, crossing their I’s and dotting their T’s and yet the material evidence still did not support arresting Zimmerman.  Enter the Department of Justice and the FBI, but still the same status of Zimmerman exists, no arrest.  If there is any evidence against him, it has not been divulged in any manner.

Despite the opinions of whether or not Zimmerman should have followed Trayvon, left his truck, or tried to ascertain the whereabouts of the suspicious person who turned out to be Trayvon Martin, still nothing points to any illegality or “reckless” conduct.  It is not “reckless” to identify a suspicious person in your own neighborhood and seek to keep them in sight while you call police.
And for others the opinion that Zimmerman was armed appears to be a point of contention.  But Zimmerman had every legal right to possess a firearm.  It was registered appropriately and voluntarily, he held the necessary licensing allowing concealed carry, and he was well within his legal rights to have a gun on his person.   This point is substantively moot, and highly unlikely to matter at all.
The essential point is that George Zimmerman has been completely transparent with law enforcement, and apparently consistent.   Should there have been any discrepancy within any of the statements, written, recorded or verbal, the police would have ample reason to detain or arrest him.   The absence of an arrest speaks entirely to his statements being credibly considered by police and supported with the physical and witness evidence.
While there will be banter in either direction until Angela Corey finally makes a decision, one must intellectually admit that at least up to this point nothing has been found to contradict anything previously stated by Zimmerman.   This very independent trait allowing transparency, which Zimmerman feels confident with, is coincidently the very trait that would drive a defense lawyer to frustration.
But perhaps George Zimmerman actually believes what he posts on his website:

“The only thing necessary for the triumph of evil is for good men to do nothing.” – Edmund Burke

And perhaps he believes it enough to feel that honesty, transparency, truthfulness and principle will construct the shield that defends his righteousness.
