Well its not guaranteed yet but it seems likely, which sucks because the armorer is definitely guilty. The incompetent prosecutor (seemingly) wanting to "stick it" to a celebrity means that the woman who deserves to serve time for the death of a woman might get off with barely any punishment.
I really hope this at least means the end of the armorers career, I can't imagine even the smaller/shadier film productions are going to want to hire her, even if she gets let off on basically a technicality.
