AFAIK, the remaining problem is that killing is illegal unless an _affirmative_defense_ is presented, which we have not seen. We’ve seen the demolition of any imputation of malice, but the actual defense argument has not yet been presented. At this point, GZ’s only hope is that the over-charging of 2nd Degree Murder has been eviscerated; a charge of Manslaughter may remain.
It’s a nuanced point; correct me where my specifics are objectively wrong. (No, I’m not arguing GZ’s guilt, just thinking thru what the DA could pull.)
It may be that Corey's plan all along was to overcharge so that the jury would compromise with manslaughter. The blond motormouth on Hannity last night also was hoping for manslaughter--so they seem to think that is a real possibility.
