So, he doesn’t fit any one of those....
I don’t think there is a chance the prosecution will be able to prove beyond a reasonable doubt that GZ had NO reason to be in fear for his life. Just the injuries he sustained should be sufficient. The only other way to defeat the self-defense claim would be to show that he attacked TM first. There is absolutely no physical evidence to suggest that, and no eyewitnesses saw the beginning of the struggle. GZ doesn’t have to prove he didn’t start the fight - the state would have to prove he did. With no wounds on TM other than the gunshot wound and the banged-up knuckles, I don’t see how they prove that.
