a forensics lab could easily answer all these questions. hopefully fitzgerald is doing this now and if it shows (or if he has already done the analysis and knows that it shows) that judy is LYING, perhaps he is holding back this information to rebutt her with it on the stand during the actual trial or holding it back so that he can threaten her with perjury and obstruction again at the last minute (on the eve of her trial testimony) in order to surprise libby's defense.
i am unsure of the legal rules here -- does fitz have to turn over such info to the defense? or can he hold it back if he only intends to use it to rebutt?
are there any lawyers out there who can answer?
