Zimmerman has already been proved guilty, now it's just a question of punishment. [View all]

As the title states, Zimmerman has already been proved guilty by his own admission that he pulled the trigger on the gun that shot Trayvon Martin. The only question that remains is whether he will be punished by the state for his action or whether he can prove by the preponderance of the evidence that he did so with an exculpatory excuse.

An exculpatory excuse is an affirmative defense that is used by defendants who admit their guilt but belief their actions are justified by the circumstances. In this case, Zimmerman is claiming self defense. If he can prove that to the jury's satisfaction, he will be acquitted.

So has Zimmerman proved that he killed Martin in self defense or has he merely asserted a theory that is possible but not proved? From what I've heard, the single witness that allegedly saw the event has now changed his testimony to state that he did not actually see who was beating whom.

So has Zimmerman proved he acted in self defense?
