We've got zero idea what they said to each other right before that fight started or if they said anything at all but I just have this mental image of Zimmmmmerman trying to grab Trayvon's arm and a fight starting. I also don't really buy that Trayvon made a grab for his gun. It's very possible that Trayvon was in the process of skittling back after Zimmmmmmerman got it out and Zimmmmmmmerman still pulled the trigger. I don't think for a moment that the burden of beyond a reasonable doubt has been met in this case for either murder or manslaughter nor am I so convinced in my impression of the people and the situation to believe I'm spot on with my guess. But I just can't shake this image of Zimerman reaching to grab Trayvon.
The jury doesn't even know that manslaughter in which a firearm was used carries a maximum sentence of 30 years. I could never, ever find him guilty of that if I knew.
