Well you're long on conjecture but it appears you're short on FACTS as well as knowledge of Florida law. But hey that's the trade mark of the lynch mob mentality, please carry on with your persecution.
Information below is from the department of government in Florida responsible for issuing carry permits. I can't seem to find a reference that justifies what Zimmerman did. I can find references that indicate Zimmerman should be considered a criminal and punished for what he did. I'm aware there is a "stand your ground" statute in Florida, however I do not believe Zimmerman can be the aggressor (he initiated the events by his actions) and use that as a defense to shooting someone even if that person is kicking his butt despite being 11 years younger and of significantly lighter body weight.
I can easily find references that state you cannot do what Zimmerman did without being considered a criminal subject to prosecution under Florida law. In addition, I can easily find a reference that states Zimmerman signed an oath swearing he understood and would follow these laws in order to be issued a permit.
Lawful Self-Defense - Weapons - Division of Licensing, FDACS
Q. Are there special laws that apply to the use of
Handguns?
A. Yes, special laws apply anytime anyone uses deadly force,
whether or not the weapon is concealed. Florida law defines deadly force as
force that is likely to cause death or great bodily harm. When you carry a
handgun, you possess a weapon of deadly force. The law considers even an
unloaded gun to be a deadly weapon when it is pointed at someone.
Q. When can I use my handgun to protect myself?
A. Florida law justifies use of deadly force when you are:
- Trying to protect yourself or another person from death or serious bodily
harm;
- Trying to prevent a forcible felony, such as rape, robbery, burglary or
kidnapping.
Using or displaying a handgun in any other circumstances could result in your
conviction for crimes such as improper exhibition of a firearm, manslaughter, or
worse.
Example of the kind of attack that will not justify defending yourself with
deadly force: Two neighbors got into a fight, and one of them tried to hit the
other by swinging a garden hose. The neighbor who was being attacked with the
hose shot the other in the chest. The court upheld his conviction for aggravated
battery with a firearm, because an attack with a garden hose is not the kind of
violent assault that justifies responding with deadly force.
Q. What if someone uses threatening language to me so that I am afraid for
my life or safety?
A. Verbal threats are not enough to justify the use of deadly force.
There must be an overt act by the person which indicates that he immediately
intends to carry out the threat. The person threatened must reasonably believe
that he will be killed or suffer serious bodily harm if he does not immediately
take the life of his adversary.
Q. What if I see a crime being committed?
A. A license to carry a concealed weapon does not make you a
free-lance policeman. But, as stated earlier, deadly force is justified if you
are trying to prevent the imminent commission of a forcible felony. The use of
deadly force must be absolutely necessary to prevent the crime. Also, if the
criminal runs away, you cannot use deadly force to stop him, because you would
no longer be "preventing" a crime. If use of deadly force is not necessary, or
you use deadly force after the crime has stopped, you could be convicted of
manslaughter.
Q. If I get a license to carry a concealed weapon, can I carry it
anywhere?
A. No. To get a license you must sign an oath that you have read and
understand the Jack Hagler Self-defense Act (Section 790.06, Florida Statutes).
That statute lists several places where you may not carry a concealed weapon.
You should read subsection 12 for a complete list, but some examples are
football, baseball, and basketball games (college or professional) and bars.
A cool head and even temper can keep handgun carriers out of trouble. You
should never carry a gun into a situation where you might get angry.
Summary
1. Never display a handgun to gain "leverage" in an argument, even if it
isn't loaded or you never intend to use it.
2. The amount of force that you use to defend yourself must not be excessive
under the circumstances.
- Never use deadly force in self-defense unless you are afraid that if you
don't, you will be killed or seriously injured;
- Verbal threats never justify your use of deadly force;
- If you think someone has a weapon and will use it unless you kill him, be
sure you are right and are not overreacting to the situation.
3. The law permits you to carry a concealed weapon for self-defense. Carrying
a concealed weapon does not make you a free-lance policeman or a "good
samaritan."
