from him it's so interesting because anytime a jury gets to hear the defendant's voice when he or she doesn't testify, it's very powerful. usually it would be in the form of a wiretap evidence or other recorded evidence. so usually it's the defendant saying things that they wouldn't want anyone else to hear that directly. locates them in the criminal behavior. here. this also implicates him in the criminal behavior, but not in the same way. this is a book of course, that he voluntarily wrote and that he decided to narrate himself as an audio book. >> so i agree with pollock could cut both ways. >> of course it has evidenced in its the prosecutors want to get in around the timing of drug use, but there isn't his own words talking about his struggle and i think that for the sake of completeness, if the defense wants to put other portions in, if they're relevant at all, the judge will probably let them do so. so they may get a lot of information from hunter biden in his own words, so that he doesn't have to testify in a way he may get out this notion
