Ifill the worldwide toll in the Ebola Outbreak has risen again. The World Health Organization put the casualty count today at nearly 3,900. Thats out of 8,000 confirmed cases. And in spain, there was new unrest linked to the infection of a nurse. Neil connery of independent Television News is there, and filed this report. Reporter anger on madrid streets. The authorities handling of this ebola crisis under attack. These protesters dragged by police from the block where the infected nurse and her husband lived. They were trying to stop the couples dog from being put down by officials, but as the world beyond looks on, its the Bigger Picture here thats getting serious concern. The nurse, theresa ramero ramos, seen here with the dog, says she may have been infected by touching her face with a glove as she changed her protective clothing. Anna gomerth, a friend of the nurse, told me shes no faith in the governments response. The people are afraid and angry because they dont know anything about this illness or whats happening here. According to her union, the nurse start help three times over a week before she was tested for ebola. Last tuesday, she reported a fever, but was told to take paracetemol. She rang the hospital again on thursday, but no action was taken. When she rang again on monday, she was told to go to a local hospital, where she was kept on a public ward behind only a fabric screen and some tape. Only when her ebola test came back positive was she finally transported to the carlos the third. Theres a deep sense of mistrust here at how the authorities are handling this crisis. Aside from the medical efforts to contain this outbreak, regaining the publics faith in the coming hours and days is going to prove crucial. Today, the spanish Prime Minister boasted the countrys Health System is one of the best in the world. Back in the suburban block, where the infected nurse and her husband lived, the residents may beg to differ. Ifill well get a closer look at what the u. S.

Woodruff Islamic State forces made a new push on the syrian town of kobani this evening despite Coalition Air strikes.

Led Campaign Needs to be even stronger. Meanwhile, president obama met with u. S. Commanders at the pentagon to discuss overall strategy in syria and iraq. Our struggles continues alongside our partners. It remains a difficult mission. As i indicated from the start, this is not something going to be solved woodruff the battle for kobani also triggered more violence in turkey, where kurds are demanding action to help their brethren in syria. Police used water cannon and fired tear gas at demonstrators in the latest clashes. Officials said at least 19 people have died in two days of rioting. Woodruff lawyers for kenyas president have asked the International Criminal court to toss out charges of crimes against humanity against him.

Reporter the Emergency Operations center at c. D. C. Headquarters in atlanta never sleeps. A quiet home belies the friendly activity here. Its under 2014 ebola international.

We are the watch team here at the c. D. C. We are basically like the c. D. C. s nin 911. Reporter gordon may oversees the watch station which gets calls from the public, media and health officials. Theyre seeking information on what to do with their patients, theyre seeking information on waste disposal.

D. C. And others face add flurry of criticism including the hospitals response when duncan arrived. This is the way i look at it is that preparedness is really a process, its not a stage or an activity. Its a process, a state of mind. So what we need to do in this situation is to learn everything we can to try to make it go better. Hopefully there wont be, but if there is another case. Reporter the c. D. C. s attention goes well beyond the u. S. Border. The Global Migration Group focuses on air and sea travel, including outreach to passengers. The groups leader is dr. Marty se etron. The most important thing were trying to do is help fill in a gap between the Public Health sector and transportation sector in terms of readiness, our job is to train people to ask questions about symptoms, how to ask questions about exposure, risk, whether they had contact with an ebola case and how to measure objectively in a safe way temperatures of people who are intending to leave, identify those people and move them out and prevent sick people from getting on airplanes that could potentially spread. Are you focusing mostly on liberia . No, all of the reporter epidemiologist amy summers is a disease detective just back from liberia. More people have died there than any other country. Summers had to find those that may have been exposed, a process called contact tracing. There are a lot of challenges in liberia and i think probably the host challenging part of it is that theres a lot of stigma attached to people there, so people are basically running away because nobody want to be associated with it, so there is one case that we went out with and, by the time we got there, all of the contacts of that case had fled the area. Those in west africa process specimens to determine if patients had ebola. In atlanta scientists are working on genetic sequencing to see if the virus changes. I worry when people have irrational fears of ebola but there are racial fears as well. If you are a Healthcare Worker taking care of a patient with ebola you better be scared and use that fear to make sure that you do absolutely everything right when youre caring for that patient. Well, you can go over to the reporter the c. D. C. Has sent scores of its own staff to africa, but many more are needed. Thats why theyre offering handson exercises like this one in alabama earlier this week. 36 Health Care Workers came to this rural spot to learn how to put on personal protective equipment, suits, masks, boots and gloves. Dr. Michael young, an influenza expert who turned his focus to ebola put the curriculum together. What we try to do is create a facility here that mimics an ebola treatment unit in west africa. Were not trying to recreate a u. S. Hospital where theres much higher levels of technology lable, and were not trying to recreate a General Hospital in west africa. Its a specific facility for caring for ebola patients. What we ask our students to do is do a practical, handon exercise every day of the threeday course. Today they did a simulated blood draw. For the nurse, drawing blood is easy but wearing heavy gear may be tougher when she leaves for liberia this weekend. Its warm here. Its hot in west africa. Its a challenge being able to see when it fogs. Its a challenge, the dexterity of your hands when you handle any fluids that could possibly infect you is most important and making sure that you do that safely. Reporter captain paul reed will be in charge of Clinical Operations at the new hospital the u. S. Is building in liberia. The public healt Public Health r has been deployed to hot spots many times but, for the father of four this, assignment feels different. My family is used to me traveling and being deployed over a long period of time, a 20year career. This one has a little bit different flavor, obviously, and theres some anxiety on the part of my family as you can imagine, but they know i will be smart about what needs to be done and im safe as well as the folks im taking care of are safe. Reporter but training doesnt happen overnight. The challenge is keeping pace with the fastmoving epidemic. We can run 35 to 40 students per course. We can run one course per week. We intend to run a course every week until the demand goes away and that takes a year or two, well run it for a year or two. A single laps can result in an infection of a Healthcare Worker so we want to make sure its done well and thats why were doing this detailed, indepth training for anyone who wants to assist with the response as an initial training. But also the stakes are so high in africa, if we dont stop it in west africa, the risk of it spreading to other parts of africa is very great. And if that happens, it could be around for years and a global threat for years, and that would have impact on how we do medical care in this country, that would have impact on travel and trade and economies and political stability. So the stakes are very high. Reporter those high stakes drive the c. D. C. Effort, but the question remains, can the agency move fast enough to combat the worst Ebola Outbreak the world has ever seen . Woodruff online, you can hear more from the Healthcare Workers and whats going through their minds as they prepare to go to west africa at pbs. Org newshour. Woodruff president obamas meeting at the pentagon today comes as there are considerable doubts over whether the u. S. Led coalition can stop and roll back the Islamic State groups advances. To help assess the campaign against the militant group, im joined by michele flournoy, former undersecretary of defense for policy during the first term of the obama administration. Shes now chief executive officer at the center for a new american security. And derek harvey he was an Intelligence Officer and special adviser to the commander of u. S. Forces in iraq. Hes now director for the Global Initiative on Civil Society and conflict at the university of south florida. We well come both of you we welcome both of you back to the program. Derek harvey, first the reports we had earlier in the program are it looks as if the town of kobani on syrias border with turkey may be about to fall to the Islamic State. Is that what youre hearing and, if so, how big a loss is this . Well, i think thats what is happening in kobani and its unfortunate for that population there. There is significant offensive activity by the Islamic State. Theyre using combined arms tanks, mortars, artillery and infantry dnr and theyre coming in on a city from at least three directions. It is expected to fall some time in the next three to five days according to the source im talking to. Woodruff and how big a loss, michele flournoy, if this happens . I think its worsened because it is right up against th the Turkish Border and that will cause cross border incursions in some areas. So its of concern but i think we have to be realistic in our expectations. This campaign wont be able to stop every i. S. I. S. Movement or to roll them back in every place. Where we need to focus is really on the most strategic areas and building up the Ground Forces that can retake and hold territory. Air power alone cannot do that. Woodruff secretary of state kerry was quoted as saying it wouldnt be a strategic defeat if kobani goes down. Colonel harvey, do you agree . I think its significant if kobani goes down just like its signature when we lost mosul and you have the humanitarian crisis and the massacres that ensues from that, and we have the capability to intercede to have an impact like we did not take in the case of the yidsies. If i was to give this campaign a grade to date. Its a d, maybe d plus. It lacks intensity. It isnt driving the enemy in a way that we need it to. Its taking some initiative away. Its degraded them some, but, overall, i. S. I. S. Continues to act like a pacman in the video game, impossibling up territory in syria and in iraq, and thats something that is going to continue to happen, unless we change the air campaigns posture, increase the intensity, resourcing and improve intelligence. Woodruff michele flournoy, what does it say that this town and other parts of syria and iraq are going down despite this air campaign on the part of the u. S. And its allies . I agree we should ramp up the intensity of the air campaign and try to be more pro active and get out ahead of some of i. S. I. S. s mostly and so forth, but whats really going to make a difference on the ground is when the iraqis are able, with our help and our support, to really start engaging on the ground when the kurds and the Syrian Opposition forces are able to engage on the ground. The problem is that is going to take time, reconstituting the forces, enabling them to be fully effective will take time and thats the frustrating part now. Woodruff what does that waiting time mean, colonel harvey . I think were looking at a year or more, and thats going to be unfortunate for the people of iraq and syria, but its also going to give the Islamic State a great deal of opportunity to entrench themselves, to improve their capabilities and make it that much harder for us to dig them out in these communities that theyre becoming well entrenched in, in iraq and syria. A year or more is too long, and we just have not put the resources in place to support building Iraqi Security forces or partnering with sunniarab tribes in both iraq and syria in order to build the capability for a force on the ground that we can work with. Its a missing component and theres not enough energy and effort into this at this point. Woodruff michele flournoy, does this put pressure on the administration to either find a way to get boots on the ground by the u. S. Or get boots on the ground faster by countries in the region . I think the pressure is to actually move the advise and assist and training with the iraqis faster and as colonel harvey said to more fully engage the sunni tribes to try to get them to start taking on i. S. I. L. I dont think the answer is large conventional u. S. Ground bonds because ultimately you have to have the indigenous folks on the ground owning this to be a sustainable outcome. Woodruff harvey, you talk to people in the military, what are they saying about how they view the success of this air campaign and, from another perspective, were hearing, now, complaints of a different sort in iraq, the u. S. Employing apache helicopters, something that wasnt expected. What are the perspectives youre hearing from folks youre talking to . Theres frustration about the inability to bring resources to bear to a fight that we have that we can engage with. The intensity as michele has talked about is not there. We dont even have ac130 gunships deployed which are ideal for this type of combat in this type of theater. So theres a lot left on the table that commanders would like to be able to engage in order to improve the air campaign. Secondly, the attack aviation that came out of Baghdad International airport, entering a nation in an attack manner is incredibly important in this environment and a capability they would like to have but it brings risk. The risk is helicopters are more vulnerable to ground fire. If you lose a helicopter in this environment, you will have to have a Quick Reaction force to get in there and extract the people. You will have to have medivac. That puts the other elements at risk. You need the capabilities in place. Im afraid of a mo mogadishu incident that does not play well internationally and at home. Its a significant problem if we do this. Woodruff i want to come back to his comment that folks in the military are telling him there is capacity left on the table by the u. S. I think thats often true in operations. The question is, you know, aligning that with a strategy, and i think here there has to be a discussion about whether theres more we should be doing, whether the risk of doing more is acceptable, and whether it really fundamentally changes the timeline. Can we get to Real Progress against i. S. I. S. On the ground inside of a year . Not a full year, but bringing the time line forward, thats the real question. Tough questions. Michele flournoy, colonel derek harvey, we thank you. Thank you. Ifill now, to gay marriage, an issue thats once again roiling republican politics for the Midterm Elections and beyond. Federal courts have been striking down gay marriage bans right and left, and then on monday, the Supreme Court stepped in, again. The justices refused to hear appeals from five states that wanted to keep banning samsex marriage. Six other states are also affected by the courts refusal. Competitive senate races are underway in at least five states where gay marriages are or could soon now be legal, virginia, colorado, kansas, North Carolina and in West Virginia, where republican Shelley Moore capito is running against democrat Natalie Tennant for the seat being vacated by jay rockefeller. She addressed the issue in a debate last night. My voting record and my personal belief is that marriage is between a man and woman and i have a long history on that dating back to when i was in the West Virginia legislature. But i believe the decision thats been made is basically saying that the states will make their own decisions, and i will abide by what the state of West Virginia decides in this matter. Ifill but a fault line has already developed among republicans. Texas senator ted cruz, who may run for president in 2016, is criticizing the court itself. We shouldnt have unelected judges striking down our marriage laws trying to impose their Public Policy notion, on the state of texas and on states where the elected legislature where states have made the decision to preserve and protect traditional marriage. Ifill far from ending the Political Part of the gay marriage debate, mondays action seems to have reignited it. Another federal Appeals Court struck down bans on gay marriage in idaho and nevada yesterday. But at the court today, Justice Anthony kennedy immediately granted idahos emergency petition to delay action. We take a closer look at the political and legal landscape surrounding samesex marriage with jonathan allen, Washington Bureau chief for bloomberg news. Jonathan, did the Supreme Courts action force this on to the Midterm Election agenda . Absolutely, as you showed just a moment ago, its already something thats being discussed in senate debates. Within 24 hours of the decision, you had political candidates talking about it, feeling they had to. I think the parties, particularly the Republican Party committees dont want to talk about it but the candidates will have to. Its moved out of the court system and back into the political arena. Ifill what are the reason for the republicans and democrats not want to talk about it . The big reason for republicans to not want to talk about it is the American Public has shifted on this issue. If you look at gallup polling in 2006, 42 of americans approved of samesex marriage. Now youre talking about 56 . Theres been a change over the last few years, you can see it in the Democratic Party primary in 2008. The major candidates said they were for civil unions or domestic partner benefits but wouldnt embrace samesex marriage. Now in 2014, looking at 2016, all of the major Democratic Candidates are going to be in favor of samesex marriage. So youve seen that happen that way, a big shift in public opinion. As far as republicans go, theres a division in their party between those who want to promote traditional marriage and those who think that this is an issue that has already passed them by. We saw Mike Huckabee the former governor of arkansas and former president ial candidate stand with ted cruz and say, look, i want to stand with a party that has guts to fight on this issue. Its not over, and if the Republican Party wont fight on it, he said hes going to become an independent. Ifill lets talk about another wellknown conservative also keeping his eye on 2016, the governor of louisiana, bobby jindal. Hes not saying what ted cruz is saying. Yeah, i mean, there are positions all over the place right now. I think this is a problem for the Republican Party. Its very divided and i think youre going to see some longtime conservatives take a different position on samesex marriage if theyre running for president in 2016 than has traditionally been the partys message. Rob portman, ohio conservative in the senate, somebody liking at 2016, he was the first republican in the senate to support samesex marriage after his son revealed he was guy then he came out and supported it. So theres a Republican Party struggling with the issue. I think the democrats dont want the talk about it at the moment because you have a lot of tough races in swing states where gay marriage is not as approved as mention ace on the National Level and i think the democratic Party Committees dont want to hurt candidates in those places by trumpeting those issues. Ifill is there a comparison to be drawn . Reminds me of what the parties are drawing on immigration where they disagree and want to move to something else. Thats something youre seeing. Youre seeing in the Republican Party theres division on immigration and a portion of the party that thinks it really has to get into the sort of situation where you are legalizing folks who have been here and then another portion of the party. The democrats, Overwhelming Senate vote for comprehensive Immigration Reform that does Border Security and temporary workers and the legalization process. So i think thats an issue democrats are comfortable with and republicans are having a hard time with, except for d. P. S. In certain swing states where that issue isnt helpful to them. Ifill the Supreme Court ruled on the hobby lobby case, a free speech and religious case, and people said the culture wars are back. Now they are not to rule on gay marriage, at least for now. Seems like the culture wars are over or are we going too fast . I think the culture wars are back. Used to be the republicans were effectively using social issues against democrats as a wedge, they split the Democratic Party. What youve seen more recently is a pendulum shift where democrats figured out how todom unified on major social issues, whether abortion or samesex marriage, and use them against a more divided Republican Party. Each party is trying to calibrate, trying to reset, reframe and to find consensus and union. Right now republicans dont have it on the major social issues and you will continue to hear democrats talk about those issues. I think they really invite and embrace the culture wars now in a way that they didnt just eight or ten years ago. Ifill a lot of calibration between now and november. Jonathan allen of bloomberg news. Thank you. Ifill my pleasure. Woodruff next, do americans expect too much from their president s . And, what makes a great commander in chief . Margaret warner explores those questions with the author of a new book. Warner Aaron David Miller is known for his decades of work on u. S. Diplomacy in the middle east in four administrations. But now hes returned to his training in American History with a new book the end of greatness why america cant have and doesnt want another great president. He argues there have only been three truly great president s, George Washington, abraham lincoln, and franklin roosevelt. And that americans should stop searching for another one. We spoke at mount vernon, home of George Washington. Aaron miller thank you for joining us. Pleasure margaret. Warner now you write here that americans need to get over their obsession or you call it an addiction in the search for great president. Why . What if you search for something you cant have . Thats the predicament were in. Weve created a sense of expectation in a job thats already somewhat already impossible. Lets say its implausible, given the nature and the complexity of the presidency, the terrifying con i thin contit politics, so many factors out of our control and we want to turn the president into a combination of Harrison Ford in air force one and superman. And the reality is we cant have president s like that anymore. Thats the real issue. We have to stop pining for the president s, the great trance transformative ones because those wont come back, seems to me, and let the president s be good and stop expecting them to be great. Warner what are the three greats washington, lincoln, and f. D. R. Have the others didnt or achieve that the others didnt . Transforming a nation country crisis. That defines greatness. Without crisis and im not talking about marginal crisis or a serious crisis im talking about a crisis that encumbers the nation for a sustained period of time. That is what separates the capacity of the greats. The undeniable greats i call them the indispensables washington, lincoln and f. D. R. The three greatest challenges the nation faced produced fortunately for us our three greatest president s. Warner but you also say they all have things in common you call them the three cs. I do. The three cs of president ial greatness, the cocktail if you will. You mix them all together you get a great president. First of all, the crisis which opens the door, the founders basically set it up this way. They wanted an energetic executive but they didnt want power to be irresponsibly collected. So crisis is what opens the door. Then if you have character and capacity you can figure out what to do with the crisis and that in essence is my definition of a greatness. Nation in crisis out of which the undeniables extract transformative change which fundamentally alters the nation for the better. And what is the essential character thats needed . The internal definition of character, the world drive the ambition, to harnest futures to a brighter enterprise, you put that together and get my definition of character which is a p you put that together and you get my definition of character which produces a pretty compelling personality even though we couldnt in the case of washington and lincoln see them or hear them. Warner go back to your point about the fact that our search for greatness in a president that keeps them from being good what do you mean by that . We have a cardboard, cartoonish view of leadership, great man, and some big woman is elected. High principal, lofty vision, great repetition and somehow by force of personality where real change happens thats not the way that change happens in america. Warner does it affect the way they approach things . Yeah, you have to read the real estate correctly alright. Lincoln inherited the most profound crisis of any president , he also midway during his tenure believed he could extract a transformative change out of it. It was emancipation. He waited for the exact moment and he dressed it up not has some transformative declaration principle but as a war measure. The emancipation proclamation. Barack obama inherits two crisis, the greatest economic recession since the great depression, and the two longest wars in American History, and believes somehow the stage is set for his capacity to transform the nation at home and abroad. He misread the real estate. Im not blaming him. Every president aspires but you need to understand the real estate and figure out what you can do and what you cant. Warner now, are you really prepared to say we will never have another great president . It would be terrific if we could have washington, lincoln and fdr in a modern guise but the realities im pretty confident we cant what we need are good president s and not good in the sense good in the sense that they are competent and effective. Good in the sense that they are morally resident and they understand the law. Harry truman once said that nixon read the constitution but he really didnt understand it. Good in the sense that they are emotionally intelligent. They are not haunted by and aspirations to greatness that go beyond the capacity to achieve. You give me president s like that and we will be on the way to getting to address some of the crisis that warner you are a middle east expert you spent your entire career in that did you have any hesitation about wading into this ground where so many president ial historians have tread i mean some people might say frankly whats aaron millers standing to offer a thesis . It is a national conversation, a conversation every american has the right to participate in because the presidency is ours, and i have a right, an incentive as all of my fellow americans do to participate in this debate and to judge and evaluate our president s, not unrealistically, or aaspirationly. I wrote the book to begin a conversation. Thank you. Warner aaron miller, thank you. Thanks so much, margaret. Woodruff we have more from margarets conversation with Aaron David Miller, on why, of the three great president s, he thinks George Washington actually had the hardest job of all, thats at pbs. Newshour. Org. Ifill now, the continuing search for a missing jetliner that captured the attention of the world. More than six months ago, Malaysian Airlines flight 370 mysteriously disappeared en route from kuala lumpur to beijing, triggering a massive search the plane was thought to have crashed somewhere in or near the southern indian ocean, with 239 people on board. A nearly twomonthlong search for wreckage and clues proved futile yielding no definitive answers about just what happened to the plane. Its been months. But now the search is back on. Jeffrey brown has more. Brown the break gave investigators to create a map of the understood water seabed and the search was resumed monday. Three ships will be involved in the next phase which could last as long as a year. Ships and planes from 14 countries served vast areas from the South China Sea to other regions. Tonight, focusing on the continuing investigation and many questions that remain and the technology of tracking planes. Our science correspondent miles obrien is the producer and reporter for the report titled why planes vanish and joins me from boston. So, miles, as the search starts, where do things stand . A what are they focused on now . Reporter . Theyre focus openeg area. Its hard to say were not still at square one on this one. Thats an amazing thing to say so many months after the loss of flight 370. Engineers in this company which operates Communications Satellites which was part of what was equipped on mh370, were able to turn capability into a positioning tool and define the location in the southern indian ocean as a search zone for the flight which went down seven hours after it disappeared from radar screens. We know its in the hemisphere by virtue of the mathematics but its in a big swath, they cant define a bullseye. So weve got to be ready for a long search here. Brown so the mystery of where it is and what happened. I know your documentary is looking at various possibilities of what might have happened from accident to human intervention. How much is the evidence pointing in any particular way . I wouldnt take anything off the table yet. All the scenarios youve heard and discussed are still in play, as far as im concerned. Its very difficult, however, to walk away from a scenario that doesnt involve some sort of deliberate action, a human handbag involved in some way. After it fell off the radar screens, it made a 180degree turn back toward the malaysian peninsula. The plane took a right turn, threaded the needle between airspace between indonesia and malaysia and flew off primary radar screens at the northern tip of indonesia. That route does not bespeak a plane that is crippled and the crew is unable to communicate or a ghost plane, if you will. That tells me somebody was manipulating controls. What was happening beyond that is difficult to say. Brown bringing the story forward, youre looking at what can be done to better track planes now and in the future. We have a clip from the film, its on the technology. Lets look at that. Here theyre using automatic dependence surveillance broadcast. It is the keystone component of next gen, an aircraft outfitted with this system determines location using g. P. S. And transmits that data back to controllers via radio which has a greater range than radar. But still, when an aircraft flies over the ocean, it will be out of range. So the industry is testing a spacebased system where planes will report to locations via satellite, wherever they are in the world. There are numerous Technical Details that need to be worked out, but adsb could eventually make blind spots a thing of the past. We have currently one aircraft under adsb coverage this moment, a united flight from chicago going to beijing. The aircraft depicted in white is using adsb to broadcast its exact g. P. S. Location automatically once a second. We see the aircraft, we know its there. We know exactly where the aircraft is at all times. Brown you refer there to Technical Details to be worked out. I know another barrier to Something Like that has been cost. Ow near or far are we from a Technology Like that to track planes in the future . Well with, its a well, its a problem. Its taken a long time. The next Generation Technology has been slow and criticized for being poorly funded and not implemented well. It needs to happen. I mean, jeff, its the 21s 21st century where were relying on 1940s technology to track an airplanes radar which has a range of 200 miles and thats it. Only 2 of the surface of the earth is covered by radar. So we have satellites that can do this, the technology is off the shelf, its just a matter of forcing the regulators to move quickly, funding it properly and insisting that the airlines equip their airplanes with this. And its difficult. The airline, this is a tough business and the airlines dont want the put this investment into this sort of technology unless they have to, frankly. So there are so many pieces to this story. I wonder as you went back to look at it all, what jumped out at you as most interesting or surprising or as still sticking with you . Well, its astonishing to me, number one, that an airliner could vanish in this day and age. Its astonishing. Brown everybody for so long, thats never gone away, right . I cant get out of my head that after all these seven months, we havent seen a seat cushion, a flight magazine or a shoe that has been floating in the ocean as some evidence there is, in fact, wreckage out there. You know, when air france 447 crashed into the Atlantic Ocean in 2009, they ultimately picked up 3,000 pieces of floating debris in the ocean. So when planes go into the ocean, its not like they just go in cleanly and disappear that way. There will be something floating. So where is it . Im mystified at that, and i remain i want them thinking i was going to have an answer to where this plane is and i walked away still wondering. Brown do you think it will be solved eventually . I dont think theyll stop looking. They cant. Its a huge, huge region. Were going to have to be very patient. Heres my worry, though when they find the black boxes, and they will one day, when they find those black boxes, it may not answer the mystery. If it shows it was a perfectly good operating aircraft that ran out of fuel and you have a cockpit voice recorder that is silent, what has that told you . You dont know who did it or why. Brown why planes vanished on no va, miles obrien, thank you very much. Youre well come, jeff. Woodruff finally tonight, a world renowned artist, barred from leaving his home country of china explores the idea of freedom in a new exhibit in americas most notorious prison. San francisco public media kqeds mina kim takes us behind the scenes. Reporter so much about this exhibit is different beginning with how you get there, by ferry to an island in the middle of San Francisco bay. Most of these passengers are going to tour the legendary former prison, alcatraz. Within its crumbling walls, seven new works were stumbled upon by artist and chinese dissident aei weiwei. We came to see the process of installing an exhibit. This will take up an entire space . Entire space. There are more than 100 kites that comprise the body of the dragon. Reporter exhibit curator. The artist had been released from detention by china for alleged tax evasion. Authorities say it was more about his suppressing criticism of the chinese government. The exhibition is what is freedom. As you walk through the works, you get a sense that this is a very central theme, a very important idea he is addressing. Reporter he has been unable to leave china since 2011 after authorities confiscated his passport. Finding freedom within constraints is a worthy challenge judging by his age studio. His inability to leave the country is hard. For an artist to be unable to see the venue and unable to interact with the audience, if i had to imagine the toughest restriction of an exhibition, that would be it. Reporter he conveys the situation in a giant dragon kite installed in a prison where prisoners once made uniforms for the army. It will be suspended, flying, free, but also restricted within the building, so this is a really interesting conversation between control and freedom. But what does it mean to be in prison . What is a prison . Reporter so much about this exhibit is different, beginning with how you get there. For most visitors to alcatraz, this is probably the only prison they ever will be close to. So what thoughts are evoked when they come to a prison . We felt that the aei weiwei exhibition would be an opportunity for visitor to explore the thoughts. Reporter the park service had to seek clearing from the u. S. State department to host one of the most vocal itics of chinas government on federal land. The challenges of bringing the work to alcatraz only added to the injury. The entire island is an historical site without a power grid or freshwater source. We basically cannot touch the walls. We cannot touch anything. We cannot add anything. Its a hanging installation, like the prisoners themselves, it is only there for a period of time. Reporter this piece was shipped by barge and pushed up a 13story hill, transformed solar collectors fromty bet. Some of alcatrazs bestknown prisoners include al capone or the anline brothers who plotted a daring escape. Last known are the Political Prisoners held on the island during the time alcatraz was a military prison. Phelps oversees visitor programs at alcatraz in. The military prison era, around 1985, there was a group of indian elders that were brought to alcatraz because they refused to send their children to school under the armys direction. They wanted to raise their children in the hopi tradition. Reporter a hopi chant echoes against the walls of a former psychiatric observation cell. Here are the poetry and music of people in prison around the world for expressing beliefs. And prison riots who criticized vladimir putin. In a piece titled trace the faces of more than 175 dissidents are fashioned in leggos. Largely unknown. Aei weiwei wants to make them familiar. And to have the opportunity to find out more about their lives and stories has been enriching. Reporter the exhibit includes position phis for the men and women held in the middle east, africa, asia, and theres edward showe snowden wanted fork u. S. Classified documents. Some consider him a patriot, others a traitor. Here, visitors are asked to write preaddressed postcards who people who are exiled and who are deemed prisoners of conscience. Chad says i walk the fine line. Theres a huge debate about who aei weiwei is in the sense the folks in the art world are concerned hes too much activist and not enough artist. The vehicles in the activist world think the opposite. Reporter his activism gives him a stardom few others enjoy. His artwork is in high demand. Will his work change . Art done well has the ability to communicate viscerally issues that or to snake its way into us through beauty or through the way we view it that a stray demonstration or poster would never achieve. Reporter the show runs until the 26th. Woodruff again, the major developments of the day. The first patient diagnosed with ebola inside the u. S. , Thomas Duncan of liberia, died at a dallas hospital. And, federal officials announced new ebola screening at major International Airports for travelers arriving from west africa.
