[ZEROSPHERES]

Homicide is excusable when committed by accident and misfortune in doing any lawful act by lawful means with usual ordinary caution, and without any unlawful intent, or by accident and misfortune in the heat of passion, upon any sudden and sufficient provocation, or upon a sudden combat, without any dangerous weapon being used and not done in a cruel or unusual manner.

Florida Statutes 782.03 - Excusable homicide

The use of deadly force is justifiable when a person is resisting any attempt to murder such person or to commit any felony upon him or her or upon or in any dwelling house in which such person shall be.

Florida Statutes 782.02 - Justifiable use of deadly force

I don't see where the first one applies in that zimmerman did have a dangerous weapon and the second one is a stretch because it may have been Trayvon who felt the need to protect himself from zimmerman taking his life. Zimmerman had the gun and I think he intended to use it if necessary, otherwise he would not be carrying it on his person, and most probably if he didn't have the gun he would never have had the gumption to to what he did. He would have stayed in his house where he could cower in safety or in his truck where he could have the protection of 250 horses to flee back home.
