I learned a very simple rule long ago, if you are going to carry a weapon as a civilian/citizen, "It is a life insurance policy" nothing more nothing less, you only pull the weapon to protect your life or that of another... If you pull the weapon, then intend to kill, and know that you will have to deal with the fallout...

You will probably get charged, and even if found innocent, you will probably lose in civil court, very very few shooters "get away with it" so to speak, especially if you are not inside your own home...

The right or wrong of the shooting has very little to do with the outcome, this case is a prime example Zimmerman cannot win, he will have his entire life destroyed regardless of if he was justified with the shooting...
When he put on a gun he made a choice, as do I, and every other person that carries, and only he knows if the was justified in using his weapon, no Judge or Jury will ever know the truth... Nor will we

That stupid old saying "I would rather be judged by 12 then carried by 6" well George made his choice...
