I don't believe the State has presented any such evidence have they?
Without them trying to present that claim, why would you even mention it as a possibility here?
My post was intended to point out that there are scenarios where losing a fight does not authorize you to use lethal force.
I specifically stated that this does not appear to have applied to Zimmerman, since apparently even the state hasn't claimed it, as you say.
However, I'm not following the trial evidence very closely. Too busy.
