i mean, how do they convince australian authorities or anybody else that we are very much convinced that what we sheared a pulse from the black box? sure. one thing they can do, at least i hope, they recorded what they heard previously. start by handing that over, so other people can analyze it and have a look at it. the second part is going to be up to the joint command in australia right now and i m i saming they re playing under those guidelines. there s probably a mechanism set up where if you see something, hear something, how you then pass it up the system. it doesn t seem to be what happened so far. it seemed like it came out of the media first. the chinese media when we first heard about this. so we ll have to sit back and watch how it s handled from here on in. david gallo, thanks so much. much more on these reported sightings and audio hearing
the defense claims that it is not possible to say who was screaming on that call. joining me now is former criminal prosecutor faith jenkins, and nbc news legal analyst lisa bloom. thank you both for being here tonight. thank you. thank you. faith, the 911 tape is a critical piece of evidence in the trial. the audio hearing resumes tomorrow, and it s all about the analysis of whose voice is screaming. what do you expect the judge to rule? i still think the judge is going to rule to allow this expert testimony in and let the jury decide how much weight they re going to give to the experts testimony. let me be clear about something. i think if the fbi had been able to analyze this tape and come to a clear conclusion about who was screaming, i think this case would be over. that s how clear and important it is. because the person who is screaming, the inference is that person is the one who was being attacked. now lisa, how important to the defense using self-defense
