tv The Daily Rundown MSNBC July 1, 2013 6:00am-7:00am PDT
>> and richard thinks that's a big problem in the middle east and a problem for the white house, too. the demonstrations are going to continue. >> i wear a tie, get dressed up, and still get no respect from you. thank you very much. now it's time for the daily rundown with mr. peter alexander. >> peter? gentlemen, thank you. good morning from washington. it is monday, july 1st, 2013. this is the daily rundown. i'm peter alexander in today for chuck todd who is traveling with the president in tanzania. on your screen right now, we're looking live at the courtroom in florida where george zimmerman's second-degree murder trial scheduled to start literally at this moment. we have already heard from more than a dozen witnesses out of a potential 200 potential witnesses. prosecutors have called, i think the exact number is about two dozen so far. today the lead detective who investigated the case will take
the stand. they'll likely ask him about the investigative report that he wanted to charge zimmerman with manslaughter. the defendant sitting down at his seat. i want to bring in nbc's ron mott covering this live in sanford, florida, as well as msnbc legal analyst lisa bloom. ron, very quickly, if detective ser eno is called today, and it could be a couple days worth of testimony, how significant is his testimony? it seems really the first contact, the first police contact with george zimmerman after the shooting took place. >> yeah, good morning, peter. if detective serino gets up here, it will be gripping testimony. almost from the beginning of his interrogation of george zimmerman, he had suspicions. george zimmerman made a statement to please, and then came back with a video a lot of folks have seen where he sort of reenacts what happened. what detective serino was
drilling down into is george zimmerman's story, is why he was following him. of course, you hear it on the non-emergency call george zimmerman made. they asked, are you following him? and george zimmerman said, yeah. and the dispatcher said, we don't need you to do that. and serino asked, why are you following someone you claim to be afraid of? take a look at the statement that he made in his statement. he said this report is inconsistent of a person who stated he was in fear of another subject. he went on to state that george zimmerman dismissed several opportunities to, quote, defuse the circumstances surrounding their encounter. and what they talk about is when he had his encounter with trayvon martin, he asked george zimmerman, did you tell him you were head of the neighborhood watch? and he said no. if you read the transcript, and serino was befuddled by this. peter, back to you.
>> thanks. lisa, as you sort of tee up this week for us, more specifically, this day, how has the state done? how, in your opinion, has the prosecution done so far in this case and what challenges are facing them in the week ahead? >> the prosecution has been building its circumstantial case bit by bit. that's how it works in any murder case when there's no direct witness to the shooting. now they'll get into the neighbors who saw part of the altercation, nobody saw all of it. on cross-examination the defense made a lot of points with the prosecution witnesses last week. many times they seem to be turning people around. i'm very interested to watch this detective chris serino testify, because he'll testify about george zimmerman's inconsistencies. win i think the prosecution is hoping this will turn this thing around for him. >> ron, we spoke just before coming on the air today. one of the conversations we had was about trayvon martin's own mom, sabrina fulton, who could very well testify this week, or in the days ahead.
why would her testimony be significant? what would she help to do for the prosecution? >> well, i think lisa's right, the state is building its case piece by piece. i think if and when sabrina fulton gets on the stand, she'll be a character witness for her son. don't know if she's going to get into who is screaming on that 911 call. six women on the jury are parents. she is probably going to try to make some connection with them, this is a son she lost, a son, a teenager, had some bumps in the road, but was a good kid all in all and simply trying to get back to his dad's place that night. she could be a compelling witness if and when she takes the stand. >> lisa, i want to get a sense from you of john good. he was a state's witness. some say he bolstered the defense more than the state. tell us more about his testimony and what happened there. >> no question he was the best witness for the defense so far.
yes, he was called by the prosecution, because their job is to do justice, not just advocate for a conviction. they have to call everyone who has relevant testimony to give. if they don't, the defense would have called him and said, look out, the defense is hiding the ball ladies and gentlemen of the jury. so they had to frame his testimony. but on cross-examination, he said, really, the core of a defense self-defense case, and that is that george zimmerman was on the bottom, trayvon martin was on the top. that trayvon martin was pounding him, m, ma style, mixed martial arts style. that zimmerman was yelling for help. all this happened just moments before the bullet shot rang out. now, he had inconsistencies with his prior statements as well. he had to limit his testimony to what he could remember. he did not see george zimmerman's head being pounded on the sidewalk as zimmerman claims. had edidn't corroborate other parts of the story. but overall, very strong testimony for the defense. >> just from a layman watching this, lisa, we have heard
throughout this case that george zimmerman said that his head was banged against the concrete, yet the bodies were found on the grass. has anybody tried to explain that sort of inconsistency? >> zimmerman i believe was asked about that by law enforcement. we may hear testimony about that as early as today. he said they moved onto the grass after initially his head was banged on the sidewalk, to support the point that you're making, no blood was found on the sidewalk where he said this incident happened. >> we heard from ron a second ago about trayvon martin's own family members. it seems likely his own mom might be called to the stand to testify in some form about the voice that we heard on that 911 call. would her testimony be critical? is that 911 call going to be very important in this? it seems it's really hard for anyone to identify who's screaming. >> i think her testimony has the potential to be very, very emotionally powerful. who better than a mother to say, that was my son screaming,
begging for help on that call. i know that was my son. she's said that from the beginning. she said that to law enforcement. she has not wavered in that argument. >> we're looking at the screen on the left. there's sabrina fulton, trayvon martin's own mother. tracy martin is the father of trayvon martin, sitting there on the side right now. as we, again, keep you up to date on the live pictures taking place inside the sanford, florida, courtroom as the testimony begins today, we'll take you into the courtroom. we're joined by ron mott on the ground there, and lisa bloom, who has been our analyst throughout this right now. ron, what other voices may we hear from in the days and weeks ahead? it could either be the medical examiner or another individual from the medical examiner's office that could give us a better understanding about ballistics and how the shooting took place. what would we hear from that testimony? >> as the prosecution is building its case, it started
with the witness the around the neighborhood there, and they moved friday to some of the first officers who responded to the scene. if we get to detective -- the two detectives, ser ino and livingston here today, and maybe more into the medical side of this, the injuries that trayvon martin sustained. there are some people out there who believe george zimmerman was on top. on friday, the prosecution got john good and some of the other witnesses to talk about the -- this mma, ground and pound, that george zimmerman's attorney was trying to put out in theory, when someone's crouched over you and banging your head into the pavement, or mat as it is in mma wrestling. the physician's assistant late friday said george zimmerman went into the doctor's office in september of 2011, about six months before this happened complaining that he wasn't sleeping well. it turns out he had been exercising three times a week using mma. i thought that was an interesting twist to this case. but expect more ballistics
testimony this week. >> ron and lisa, we'll ask you both to stay with us right now. we'll take you inside that courtroom as we hear from the fbi senior audio electronics engineer. today's first witness. >> speech analysis, and acoustic analysis of signals we encounter, including gunshots analysis. and lastly, also as a senior scientist, i provide advice, guidance, recommendations for the operational technology divisions, in the fbi field office. >> doctor, how long have you been in your current position? >> since 2009. as a senior scientist, for four years. and prior to that, i was also hired in a similar position since 1996.
>> tell the ladies and gentlemen of the jury essentially what it is that you have done, how long you've been in this field, and what has made you sort of qualified to hold your current position. >> well, initially, when i was doing my ph.d. and thesis at michigan state university, i got into this forensic recognition as part of my thesis. and when i graduated with the ph.d. degree, i taught at michigan state as a professor for 18 months or so. and after that, i moved to los angeles county sheriff department in los angeles, california, to take up a federal research project for the development of computer voice recognition system.
i stayed at los angeles county sheriff's department for seven years, since 1985 to 1992. and my title with the sheriff's department was voice specialist. and then consequently, i joined the fbi in august of 1992 for the same responsibilities that the work i did. and i think i was qualified by the fbi to conduct forensic examinations on the body of evidence in 1994. and ever since i've been doing this kind of work, until today. >> doctor, have you -- you mentioned a ph.d. thesis. have you done research in this field independently of just your work?
>> yes. my first independent scientific work would be my thesis. this was titled as recognition by using spectrum. when i moved to los angeles, the research grant was provided to continue my work as i enrolled in the thesis, under the project name title computer voice recognition system. then when i joined the bureau, i started specific modernization effort of the fbi identification. since the early part of the 1960s, the fbi was using so-called spectrum voice comparison, commonly known as
voice prints. and it was getting to be very ineffective to establish scientific validity, because of the subjectivity and the examination involved. so in 1997 -- >> the fbi senior audio electronics engineer. we're going to take a quick break. when we come back, we'll take you back into the courtroom for more of the george zimmerman trial. and we'll take you live to this as well. president obama in his final full day in africa today. specifically tanzania, the last leg of his week-long trip to that continent. we do expect to hear from him later this hour. when it happens, we'll bring that to you live. but first, a look ahead at politics planner. you're watching the daily rundown right here on msnbc. we'll be right back. vietnam in 1972.

once again you're watching t"the daily rundown." we're hearing from the fbi engineer taking the stand. lisa, give us a sense as we dip back into today's trial. i want to ups better about what this witness does for the prosecution. >> dr. nakasoni testified at a pretrial hearing for the defense. we remember the 911 call where screaming is heard on the call, and the question is that george zimmerman's voice or trayvon martin's voice. this expert witness testified for the defense that nobody could make out who that was. nobody could testify to a degree of scientific certainty whose voice it was.
now, curiously, he's been called as a witness by the prosecution. i'm interested in what he has to say. >> let's take a listen to what he has to say. again, more coverage of the george zimmerman trial. >> this technology still must be supervised by properly trained examiners. >> let me start with the idea of what kind of sample you need, or a position in your position needs in your lab to sort of be able to even conduct an analysis. what is it you're looking for? >> as part of the standard operating procedures, what we do at the laboratory, first, before we do any analysis, would be to evaluate the suitability of the data. and we check and listen very carefully, and then want to make
sure the speech sample we have at hand is naturally spoken. it would be devoid of disguised attempt. any evidence of intoxication. they must be removed for analysis. and also we pay attention to the emotional state of this speech. if the person is uttering voice samples, with extreme happiness, the voice would be joyous, including lots of giggling and laughter. those must be removed from the analysis. sometimes we run into the voice being uttered when the person is going through stress, or undue depression. this must also be removed. and any other unnatural voicing, like yelling, screaming, this type of voices must be removed
for the analysis. and that is the standard operating procedures. and when the speech is determined to natural, then we check the other aspects of the conditions. for example, the duration must be at least 30 seconds. after, you know, blank or silence removed. usually we can do meaningful analysis if the voice is down to one minute, up to three minutes or so. after three minutes, the performance sort of hits a ceiling. but when the sample drops down to only 10 seconds, 14 seconds or so, the examiner has to conclude that the voice -- the duration is not really good enough for us to do an analysis. and then we will also check the amount of the reverberation, including the speech.
if there, say, a long time in reverberation in the recording, we remove. we do not proceed with the examination. another thing is that, suppose we have two voices to compare. one coming from recorded, incriminating recording, and the other voice is coming from a suspect's voice recorded in the, you know, quiet room, where the other voice is through a telephone line. and if that telephone line has a bad quality, you know, these days most of the telephones, carries decent quality. it can be usable. but depending upon the, you know, the cell phone type, poor type of cell phone, that distorts a human voice. and when we have to confront this kind of disparity between the two voices, we are comparing, the examiner is mandated to stay away from
further analysis. >> so you've talked about sort of the -- some of the factors that affect your ability to conduct an analysis. you mentioned that there are variations in what is going on with the speaker, in terms of their mental state or emotional state, the way the speech is expressed. and you were just talking about sort of variables that could go on with the mechanism of the recording, the cell phone distortion and that sort of thing. are there other environmental factors, you know, the distance between the recording and the microphone, for example? are there other factors over and above those with the speaker and the microphone that could have an effect? >> yes. thank you for bringing that up. the effects of the distance to the voice is also regarded as,
something that we have to be careful. there are two terms that describe those. the first one is the far field recording versus near field recording. when we hear people talk on the phone, our lips are very close to the microphone, maybe an inch away. that's a typical near field recording. it captures our voice very clearly. on the other hand, when the person is, say, at the far end of the room, and there are, you know, say 10 feet, 15 feet away, we call this voice, when captured by recording system, we call it far field recording, or far field voice. and far field voice has problems, because not only does it weaken the signal, it has a noise with it.
mixed with the noise created by the room and also reverberations and echoes created by multiple bouncing walls. that sort of smears -- >> we've been listening to dr. nakasoni right now. we'll be right back for more from the zimmerman trial, live from sanford, florida. we also expect as early as today to hear from the lead investigator coming up. that could happen at the end of this witness. the state's 23rd witness. and the president is expected to be speaking from tanzania shortly. we will bring you there live as well. we'll be right back on "the daily rundown."ey don't now it y. they will. it's a steak-over. steak was excellent. very tender. melts in your mouth. it was delicious. tonight you are eating walmart steak. what???!! good steak. two thumbs up? look, i ate all of mine. it matches any good steakhouse if not better. walmart choice premium steak in the black package. it's 100% money back guaranteed.
bounce is great because the freshness lasts for weeks in the drawer. why can't everything stay fresh that long? [ male announcer ] how do you get your bounce? [ man ] lasting freshness. . we're back now live with more live pictures here of the george zimmerman trial, where an fbi expert identifying voice data is testifying for the state. we want to go to lisa bloom. lisa, help us, if you can, break this down. has there been anything you've
heard so far that is significant? >> dr. nakasone is an electronics engineer and is now just giving his background and qualifications, which both sides agree is an expert in the area. now we're getting to the 911 call where someone is heard screaming in the background. >> let's listen to the testimony. thank you. >> the portion was around 45 seconds. that's from the beginning of the recording, until there was a loud noise, almost like a gunshot-like audio event. and that duration was about 45 seconds. we listened to the entire conversation exchanged between the female caller and the female 911 operator. and when i was listening to those conversations, of course,
i xo hecould hear the voices gon the background. an altercation. somebody asking for help. and that yelling, or screaming, we can call it screaming, the screaming goes in and out. when the dispatcher and the female caller were talking. and sometimes the screaming comes up isolated from those. but since we cannot really analyze any voice which is stepped over by something else, or superimposed with other people's voice, i discounted those. and came up with less than three seconds, 2.53 seconds of screaming was sort of standing by itself. >> let me make sure i've got this clear, doctor. there were as you referenced in the 45-second portion, there was a series of that, what you described as a screaming noise,
how long total, both what you called stepped on and unstepped on? >> total, if i combine all of those segments, it reached a little less than 19 seconds. 18.80 seconds or so. and of those, 16-some seconds were completely overlapped by other voices. and less than three seconds, 2.53 seconds was the area where nothing else but the screaming was coming through. >> and what were you able to do with that amount of sample, and that type of sample? >> we checked, and i have to render my final conclusion. that type of, you know, voice sample utterance is not fit for
the purpose of voice comparisoc. and this is a mandate. and this kind of, you know, judgment is based upon the research, and also common-sense type of understanding among the scientific communities. >> so you concluded, based upon finding out what you've told us about 18 and 16 and about 3 seconds, and the type of recording, that you coauldn't make a comparison, is that right? >> that is correct. >> is there something about the nature of the sounds itself, independent of shortness of the sample or the other complications that you've already discussed, that also made it harder for you to even conduct a comparison in this case? >> in this case, signal-to-noise ratio of significant screaming
was very poor, and that was due to the distance between the telephone set, in the premise that the female caller was using. and presumed location where the altercation was taking place. but of course, we didn't have any visual information of those geometric information. but by listening, we could tell it was a far field recording. and there was another slight reverberation that was also contained in that screaming. >> doctor, independent of whether you can compare a sample like this to a known sample of someone's voice, which you said you could not in this case, are you able to -- what sorts of things are you able to tell about determining the age of a person who's giving a sample?
>> it is common belief in the scientific communities, attempt to guess at age of a person from a recorded voice is rather complicated. and often we can tell, we can approximate, but very often we know people make mistakes. when we hear on the phone someone's voice, say a young man's voice coming through, i may think, oh, this guy is very young, 20 years old probably. but it can turn out to be 55-year-old talking. or sometimes, i think maybe everybody's gone through this before, too, in your life, you may think that, oh okay, this man is very old, 30, 35, but he turns out to be only 18 or 19.
and this also depends upon the individual, too. so guessing age is a little complicated. >> tell me what you know about, for example, just the generalized parameters of the pitch of a voice, and what that means as it relates to ages, genders and stages of development. >> the pitch is -- let me just define quickly, pitch is the psychological perception of actual vibrations of the vocal cord. say like when i'm talking in this courtroom right now, probably my vocal cord is opening and close iing 100 time per second. so 100 reputations per second is called 100 hertz. and maybe 120.
the average pitch of the grown male is around 120 hertz. on the other hand, the average adult female voice has about 220 hertz per second. it's twice as high as men. now, on the other hand, a smaller child produces somewhere around 400 hertz on the average. small children have the highest pitch. now, this is based upon the speech samples while everybody's talking in a normal speech, carrying out a conversation. this pitch goes all over the place when someone, you know, in
extreme conditions. say like roller coaster ride, or a voice right before a crash to the ground, or somebody who goes through extreme emotional status. the pitch is known to raise way higher into 500, 600, 700 hertz, regardless of the age. and normally, we are accustomed to hear a person's pitch, but another phenomena along with it, when we speak, pitch is the baseline. pitch is sort of a source of energy. but the reason what we hear distinct sounds is not because of the pitch. it's created by resonance created by the tube formed inside the home vocal tract. the tube starts from the lips all the way down to the top of
the vocal cord. it's somewhere around 15 to 17 centimeters or so. this tube is constantly changing, and it creates a resonance. and that resonance can be also change the when the person uttering something under extreme -- >> you've been listening to live testimony from sanford, florida. this is the george zimmerman trial, taking place right now. we've been hearing from an fbi audio engineer, detailing the specifics of the 911 call that was made by a neighbor the night that trayvon martin was killed. he said there's about 19 seconds of screaming that he could hear, 18.82 to be exact. no one will ever accuse him of lack of specificity. we'll take you back to the trial in a moment. but there's another live event we're following right now. the president expected to speak any minute now. this is the state house in tanzania. a tropical day there. temperature in the 80s. the president's expected to walk out before the cameras a short time from now for a joint news
conference with that country's president as well. we'll bring you that live when it happens. you're watching "the daily rundown" right here on msnbc. well now i'm her dietitian... ...and last year, she wasn't eating so well. so i recommended boost complete nutritional drink to help her get the nutrition she was missing. and now she drinks it every day. well, it tastes great! [ male announcer ] boost drink has 26 essential vitamins and minerals, including calcium and vitamin d to support strong bones, and 10 grams of protein to help maintain muscle. and now boost comes in two delicious, new bars. look for them next to boost drinks. [ dietitian ] now, nothing keeps mom from doing what she loves... ...being my mom. a regular guy with an irregular heartbeat. the usual, bob? not today. [ male announcer ] bob has afib: atrial fibrillation not caused by a heart valve problem, a condition that puts him at greater risk for a stroke. [ gps ] turn left. i don't think so. [ male announcer ] for years, bob took warfarin, and made a monthly trip to the clinic to get his blood tested. but not anymore. bob's doctor recommended a different option:
once-a-day xarelto®. xarelto® is the first and only once-a-day prescription blood thinner for patients with afib not caused by a heart valve problem, that doesn't require routine blood monitoring. like warfarin, xarelto® is proven effective to reduce the risk of an afib-related stroke. there is limited data on how these drugs compare when warfarin is well managed. no routine blood monitoring means bob can spend his extra time however he likes. new zealand! xarelto® is just one pill a day, taken with the evening meal. and with no dietary restrictions, bob can eat the healthy foods he likes. do not stop taking xarelto® rivaroxaban without talking to the doctor who prescribes it for you. stopping may increase your risk of having a stroke. get medical help right away if you develop any signs or symptoms of bleeding, like unusual bruising or tingling. you may have a higher risk of bleeding if you take xarelto® with aspirin products, nsaids or blood thinners. talk to your doctor before taking xarelto® if you currently have abnormal bleeding.
xarelto® can cause bleeding, which can be serious, and rarely may lead to death. you are likely to bruise more easily on xarelto®, and it may take longer for bleeding to stop. tell your doctors you are taking xarelto® before any planned medical or dental procedures. before starting xarelto®, tell your doctor about any conditions, such as kidney, liver or bleeding problems. ready to change your routine? ask your doctor about once-a-day xarelto®. for more information including cost support options, call 1-888-xarelto or visit goxarelto.com. for more information including cost support options, (announcer) at scottrade, our cexactly how they want.t with scottrade's online banking, i get one view of my bank and brokerage accounts with one login... to easily move my money when i need to. plus, when i call my local scottrade office, i can talk to someone who knows how i trade. because i don't trade like everybody. i trade like me. i'm with scottrade.
(announcer) scottrade. awarded five-stars from smartmoney magazine. back here live on the daily lundown. the george zimmerman trial, an expert on voice recognition right now. the president is expected to hold a press conference with the tanzanian president. we'll take you to that live as well. president obama arrived in tanzania this morning after spending the weekend in south africa, where he announced a 7 billion effort to help bring electrical power to africa's poorest region, he called it power africa. and he visited the prison cell where nelson mandela spent years behind bar. >> malia is 15, sasha is 12. and seeing them stand within the
walls that once surrounded nelson mandela, i knew this was an experience that they would never forget. i knew that they now appreciated a little bit more the sacrifices that mabiba and others had made for freedom. >> we want to get to our gaggle, manny from the financial "times," and "washington post" chief correspondent, author of "the take." thanks for joining us right now. appreciate you talking some politics with us. dan, we'll start with you, if we can. this has been a trip long sort of anticipated but really took a while to take place. as we wrap up the end of this africa trip, what was the president trying to accomplish and did he do it? >> one is obviously to bring more attention to the business between the united states and africa. we talked as he's been over there of the competition between
the u.s. and china. that's one element. another element obviously as we saw in the clip is to pay homage to nelson mandela. mandela has been a shadow over this entire trip. the president hoped to meet with nelson mandela. he's not been able to do that because of the grave condition. >> i want to listen to gale smith of the national security council speaking to chuck todd over the course of this trip. chuck, of course, traveling with the president. take a listen. >> we get two returns. we get american companies that are investing. but again, we get countries that once they are producing that electricity, that allows them to attract more investment, but also allows them to educate more kids, extend health services, have healthier, more productive populations, it's a win. >> and i want to talk to you -- we were talking a little while ago about the unique challenges that exists for this president. where the expectations were set
so high, particularly in the african continent. as we learn he's going to be visiting tomorrow with president 43, president bush, w. bush, all of a sudden w. bush is celebrating africa for having done so much and this president has not having done enough. >> obviously president obama has strong links to africa. 80-plus approval ratings there. but he's been compared to george bush, because he did had a lasting impact on the content there for hiv and aids. >> talk about the challenges that exist on any foreign trip like this. certainly this one taking place with so many things happening at home. immigration. and even overseas a lot of challenging headlines right now, from new revelations, from edward snowden, as well as the illness of nelson mandela.
>> certainly when you're abroad, you get criticized for losing your attention to what's happening at home. i mean, the student loan rates set to double because of the inability of congress and the white house to cut a deal on that issue. and now the president's overseas. that's certainly an area that he has to balance very gingerly. of course, africa is one area that the president has been criticized for not spending enough time and attention to in his first term, making only one trip there in 2009, to ghana. this is an area he believes needs to be part of his legacy. >> and as we anticipate from the president right now, with the tanzanian president, a short time ago, we noticed he arrived at the state house, he drove what is now the newly named barack obama drive, formerly ocean drive. make sure that's in your gps. what headlines does he leave as he returns home? what are the headlines will follow the president back to the
united states? >> i think to some extent, punctuated by the meeting with former president bush, will be this comparison of bush versus obama in africa. i think it's a fascinating end to a trip that i suspect they did not anticipate would be part of the conversation. so i think that's one element. and as i say, i think that nelson mandela looms so large over this entire trip. and obviously the relationship between the first african-american president of south africa and the first african-american president of the united states is a powerful symbol of where we are. >> talk to us a little bit about that. obviously the president and his family were hoping to have the opportunity to visit with nelson mandela. it didn't take place obviously because of the deterioration of his health. they had a conversation with his wife by phone. they were able to visit with some of his relatives. how important has that relationship been to this president? >> i think it's been very president. no doubt mandela has been a huge influence on obama. it was very moving watching him and his family traveling around
these very historic sites. picking up on what dan said, the big question is after the headlines, after all these beautiful photo shots in africa, what happens next? is this going to be another place where obama goes to deliver great speeches, moves the country and then there's no follow-up. we've seen this in cairo and other places. what happens next? >> the president spoke at the university of cape town, where bobby kennedy gave what was viewed by many people to have been the best speech of his life. that took place in 1966. let's take a listen to some of the president as he sort of looked back at that ripple of hope speech from '66. >> on the very day that kennedy spoke here, the american civil rights leader james meredith was shot in mississippi where he was marching to inspire blacks to register to vote. it would have seemed inconceivable to people at that time that less than 50 years later, an african-american
president might address an integrated audience, at south africa's oldest university, and that this same university would have conferred an honorary degree to a president nelson mandela. >> this weekend before the president spoke at the advice of many people i read through the rfk speech, he said among other things, each time a man stands up for an ideal or strikes out against injustice, he sends forth a tiny ripple of hope. i think that hope and change is very reminiscent of what we heard from the very hope and change this president referred to not so long ago. when he comes back, there are some significant changes on the horizon, like immigration. so what is on his plate the moment he returns home to the states? >> it will be just that. i think as soon as he gets back to the country, the african trip will be in the background. the people in africa, of course, will have been delighted to see him. but in the united states we'll be right back to dealing with immigration, the fight coming in
july, in the house right now. there's no clear sense how they'll deal with it in the house. come august and september, we'll start negotiating how to deal with funding the government and raising the national debt ceiling. his problems are only expanding back home. and there are no clear resolutions in sight. >> as we look at live pictures from tanzania, we are hoping to hear from the president anytime now. certainly when you're on another foreign nation's timeline as well, he is in tanzania, where among other things, he's expected to announce an executive order. he'll be announcing about $10 million in a program to help african countries fight, among other things, they'll be fighting the poaching of rhinoceroses and elephants. this was striking to me, the horns of some of these animals, including elephants, sell for $30,000. i think that's per pound. that's more than gold, more than cocaine. real significant issues that that continent is still
addressing, even as he tries to improve its standing in the world by powering up the grid, as he sort of indicated yesterday. dan, one of the thing striking in the president's comments is the fact that so much of the african continent is continent s below the age of 35. this is sort of a real rise in power. talk about the challenges that exist between the u.s. and other sort of geopolitical rivals like china trying to get into that new market place, in a sense. >> the chinese leader was there in march as i recall. now the president is there. that highlights the competition that's underway. one of the things about africa despite the deep poverty is there has been growth in a number of these countries. that the president wants to highlight that by be there this week. we want to go to our colleague lisa bloom as we fry to juggle
two different things. we're hearing more testimony in the george zimmerman trial in florida. lisa you were paying attention while we were having this conversation. what have we heard from the fbi voice data analyst. what has he said that gives us a better case? >> most of his testimony was from a scientific point of view, he could not identify who was screaming on that 911 call. the sample was too small. now at the end we see why the prosecution called him. because he said we need a person who heard the speaker in a variety of settings. the best approach you could take would be somebody who heard the speaker not just the way they speak in a courtroom, but how they speak in a variety of settings. i think this is setting up the testimony of trayvon martin's mother who i expect will come in and testify that was my son screaming on that 911 call. >> lisa, give us a better understanding as we talked about this we heard him say the sample was only like 19 seconds -- less
than 19 seconds with talk over that. if you're analyzing jury right now, is sound that short a period of time no matter how dramatic the testimony is from trayvon martin's mom, could that turn the case? it may be the best evidence they have. >> from the jury's point of view i absolutely think it's significant. you hear someone screaming for his life. if, indeed, the jury believes that is trayvon martin screaming for his life and the gun shot then goes off, that is completely inconsistent with george zimmerman's story that he was begging for his life and trayvon martin was attacking him. so it's very important analyzing that particular piece of tape. if the jury believes it's trayvon martin, that's significant for them. >> thanks so much. you keep watching that. we're going to wait to hear from the president right now. when the president does speak in tanzania right now, we'll take
you to that. i want to talk to you about e the unique moment we'll see storm with george bush 43 at the first ladies summit taking place for a wreath laying at the embassy where there was an attack in 1998. i think is dozen were killed not far away in kenya. what does this moment represent. when you see these two presidents side by side? >> it's significant. also duck tails nicely with the africa trip given we were just talking about it. the aids initiative, very popular -- president bush's aids initiative popular in africa. president obama right now trying to establish his own legacy in africa. and also works well with his trip coming off africa. >> and it does indicate
president bush as he looms large, his shadow has been a positive for many years. it's been a challenging situation in africa for the president. zblit has. the signs greeting president bush in africa have been jarring. as somebody who's used to looking at the dysfunction in washington, it's disheartening to see two presidents working together. to think they could do something constructive together. >> dan, i want to get your thought on that. this is being hosted by the bush foundation. george w. bush will be coming and saying remarks as well. what do you anticipate as you see the men side by side? >> they were side by side at the opening of the bush library, and every former president who spoke made a reference to what george w. bush did in africa. these are ceremonies in which
people are a little delicate especially because of t43's legacy. i think this will bring more attention to that. they will be cordial. they will be as friendly as they can possibly be. it is the president's club after all. but the other is president bush 43 has been incredible on the domestic scene here. he has spent a fair amount of time as has laura bush, in africa in the ex-presidency. they have followed up on work they've done through their foundation. this is still a priority for president bush. >> which has earned the credit of this president, president obama as well. we appreciate you joining us. that's it for this edition of "daily rundown." coming up next on msnbc is

talk about the witness up there nakasone. >> i think i'm confused and lisa may be as well about what dr. nakasone has said. he's been in the fry hearing. the state was trying to bring tw evidence on what may used and what may not. once you separate the caller's voice from the dispatcher, you remove them from the audio call. there's not enough material left. and no one could say who is screaming on the tape. and maybe just maybe this is the state's way of saying we don't want anyone talking about who's screaming on the tape because no one really knows. >> thank you so much. over to lisa bloom. fill in the blanks here. why is a prosecution bringing up a es
