My understanding is the judge has the final say as to whether Fresco receives 'immunity' from possible prosecution for firearms offences in exchange for truthful testimony. She can't unilaterally determine his innocence or guilt on any such charges without a trial though.
Nel argues, and rightly so, that Fresco should have the opportunity to address the court himself before she makes a determination.
Will the judge be able to ask Fresco more questions?
ie. had OP asked RS to marry him, did OP say that RS had said yes and why didn't anyone else know about it other than OP's neighbour(not her folks, her friends, apparently not even RS if you believe the clerk where she'd gotten the valentine gift wrap from where they'd joked about boyfriends and RS hadn't referred to him as her fiance, something I would guess every single newly engaged woman would be making a point of), did OP have any other "love" interests Nov/12-Feb/13, when did OP buy the McLaren he had been boasting about and where's the paperwork to support it(how about the one he'd been telling everyone he already owned... the loaner), when OP fired the gun out of the sunroof was he scared/nervous or feeling entitled and belligerent at the "nerve" of the cop to have touched his stuff, when OP called RS about the movie/dinner plans on Feb13/12 had OP been drinking "any" alcohol that day, does Fresco know what the "sh***y" news was that OP had received that morning before the late lunch he and OP had had and where and when did that occur, how often did RS sleep over at OP's when OP was also there, ... did i forget any?
