To answer some questions people are carrying about the anticipated “next steps” one must understand the “immunity defense” as it pertains to the scheduled “arraignment hearing”.

In Florida a person claiming “self-defense” is provided an immunity hearing.  Generally the immunity hearing is just prior to the arraignment hearing, usually on the same date, just a little earlier in the day.  In essence it is connected to the arraignment and presented as a defense motion to the judge just prior to the prosecution arraignment.   Not generally a different day or separate hearing as some are led to believe; Although it could be in this case, but highly doubtful.
The immunity segment is a specific defense motion to dismiss the claims of the prosecution.  Mark O’Mara will argue before Judge Lester that George Zimmerman shot Trayvon Martin while in fear for his life,  operating under self-defense, and thereby immune from criminal prosecution.
It is valuable to understand the immunity statute itself;  For within the construct of the statute is the potential defeat of the entire position put forth by Trayvon Family Attorney Benjamin Crump, and being carried out by Special Prosecutor Angela Corey.
Statutes of Florida law surrounding Justifiable Use Of Force (Statute 776) which outlines in Statute 776.032
Immunity from criminal prosecution and civil action for justifiable use of force:

(1) A person who uses force as permitted in s. 776.012, s. 776.013, or s. 776.031 is justified in using such force and is immune from criminal prosecution and civil action for the use of such force, unless the person against whom force was used is a law enforcement officer, as defined in s. 943.10(14), who was acting in the performance of his or her official duties and the officer identified himself or herself in accordance with any applicable law or the person using force knew or reasonably should have known that the person was a law enforcement officer. As used in this subsection, the term “criminal prosecution” includes arresting, detaining in custody, and charging or prosecuting the defendant.

(2) A law enforcement agency may use standard procedures for investigating the use of force as described in subsection (1), but the agency may not arrest the person for using force unless it determines that there is probable cause that the force that was used was unlawful.

(3) The court shall award reasonable attorney’s fees, court costs, compensation for loss of income, and all expenses incurred by the defendant in defense of any civil action brought by a plaintiff if the court finds that the defendant is immune from prosecution as provided in subsection (1).

Note that in section 2 of the immunity statute 776.032 a person is “immune” from criminal or CIVIL action if they are not arrested.  Hence you understand why it was so important for Team Trayvon to get Zimmerman arrested if they are going to win their money.  The arrest itself is step one, or as Ben Crump would say, “first base“, in the determination of “Probable Cause” the force, or action taken, was unlawful.
In order for the prosecution to advance their 2nd degree murder case they must prove the first aspect of their charge.  “The unlawful killing of a human being“.

776.012 Use of force in defense of person.—A person is justified in using force, except deadly force, against another when and to the extent that the person reasonably believes that such conduct is necessary to defend himself or herself or another against the other’s imminent use of unlawful force. However, a person is justified in the use of deadly force and does not have a duty to retreat if:

(1) He or she reasonably believes that such force is necessary to prevent imminent death or great bodily harm to himself or herself or another or to prevent the imminent commission of a forcible felony; or

(2) Under those circumstances permitted pursuant to s. 776.013

Remember the key distinction between guilt or innocence in Criminal vs. Civil trials. In criminal trials the burden of proof is “beyond a reasonable doubt”. In civil trials the burden of proof is “with a preponderance of the existing evidence”; this is where probable cause comes into play. For the purpose of “monetary justice” it only takes an arrest that proceeds to trial; a subsequent conviction is not necessary.

Nor is the conviction requested by Team Trayvon.  That part is irrelevant to them and their goals.  They have specifically outlined as such.
Without an arrest, that leads to a trial, there is no standing for a civil case awarding monetary damages to Tracy Martin and Sybrina Fuller against George Zimmerman, the HOA for The Retreat At Twin Lakes, the City of Sanford and all of their respective insurance companies.
In addition, if Angela Corey’s prosecution team can successfully take the case to trial then the ground work is solidly in place for Benjamin Crump and Daryl Parks to sue the state of Florida.   Yes, their intention is to hold the State Of Florida culpable in the death of Trayvon.

Specifically, their civil claim will be the “Stand Your Ground” law that provides the immunity outlined specifically contributed to the actions taken by George Zimmerman in the shooting death of the poor, innocent and angelic child, Trayvon “Skittles” Martin.
They will argue the law itself was a significant contributory factor for the mindset of Mr. Zimmerman who was able to reconcile his action and shoot an unarmed teenager merely because he perceived he was in danger.  Yet Zimmerman was never in a position where his retreat from the initial encounter was impeded. The law fueled Zimmerman’s psyche.
Therefore Crump will argue the shooter did not retreat even though there was nothing specifically threatening him, and his mindset was empowered by his capacity to engage in armed confrontation knowing that he could at any time construct “a perception of instantaneous fear” and shoot, thereby immunizing himself from legal, civil or moral liability.
Crump will argue this statutory shooting carte blanche makes the State of Florida complicit in the killing of Trayvon Martin and thereby the family should be awarded compensatory damages for the loss of their child.   That is the big payday.   The deep pockets of the entire State of Florida.
Such was his previous $7,200,000.00 victory with the Martin Lee Anderson case.   Crump  knows exactly how to pull this one-off.   The State will settle to avoid long drawn out litigation amid a climate of political fear for any elected official who would spit in the face of Sybrina Fulton’s claim for justice and deny them.
Are you with us?  (see the child), or, are you with them? (see the hooded official)
On which side do you think the self-preservation, self-serving and feeble politicians will stand?  Nuf said…..
So, the hurdle of this immunity hearing carries all of that importance with it.   Expect to see a massive full court press from every interested party leading up to this hearing.  Everything for them is dependent on it.  EVERYTHING.
Who are these “interested parties”?   Civil rights groups, leftists who wish to see SYD eliminated from the 23 states currently in place, the Federal Dept. of Justice, gun control advocates, and the general sheeple public who believe Turtle Tunnels are more important than interstate highways, Smelts more important than farm land, and Lizards more important than energy independence, etc.   You know the crew.
