I don't think MOM wants the SA to question GZ on the stand and in a SYG hearing the SA can do that. jmo
I bet you're right about that. And I think I remember one of the lawyers here posting that even if GZ had lost his SYG hearing he could still present that defense to a jury, so I would imagine even if he didn't ask for the SYG hearing he still has the option of mounting an SYG defense in a trial.
