Margaret warner gets an update on the surveillance programs from Carol Leonnig of the Washington Post. Brown the kepler space telescope, once used to search for earthlike planets, is crippled, and nasa says it cant be fixed. We explore its legacy and ask if it can still be used for scientific research. Woodruff under a pristine rain forest in ecuador lie more than 800 Million Barrels of oil. The countrys president had asked the world to ante up in exchange for a promise not to drill, but that plan is being scrapped, as Hari Sreenivasan reports. Brown mark shields and david brooks analyze the weeks news. Just wishing i changed my ways. Woodruff and two men from two generations connected by a love of the blues are now collaborators on tour. We profile Charlie Musslewhite and ben harper. This is what the blues are supposed to do. Make you feel good. Its your comforter when youre down and your buddy when youre up. All purpose music. Woodruff thats all ahead on tonights newshour. Major funding for the pbs newshour has been provided by bnsf railway. Support also comes from Carnegie Corporation of new york, a foundation created to do what Andrew Carnegie called real and permanent good. Celebrating 100 years of philanthropy at carnegie. Org. Growing up in arctic norway, and with the ongoing support of these institutions and foundations. And friends of the newshour. This program was made possible by the corporation for public broadcasting. And by contributions to your pbs station from viewers like you. Thank you. Brown they called it a day of rage in egypt, and it lived up to its name. The bloodletting claimed at nearly 100 more lives as thousands of islamist protesters confronted Security Forces. Thats on top of more than 600 killed wednesday. We have two reports, beginning with Jonathan Rugman of independent television news, in cairo. Be advised some of the images may be disturbing. Reporter they chanted for the downfall of military rule, and they marched in their thousands. This was ramses square in cairo this afternoon, in a haze of teargas and the air ringing with a sound of automatic gunfire. Fire shots, gunfire gunfire reporter the downtown area of cairo, the biggest city in the arab world, is now as dangerous as a war zone. And as for the arab spring of 2011, well, that seems like a very long time ago. Some protesters threw petrol bombs towards a police station. gunfire we heard gunfire coming from the police stations direction. The demonstrators wheeled in a street stall as a barricade to keep the Security Forces out. They knew the police had been authorized to use live ammunition; it wasnt enough, though, to keep them away. We have no. No guns. We have no. We have water, only water. We have our bodies, only our bodies. They have stolen our votes, and we want our votes back. And we are not going to leave the streets. Whatever happened before getting the democracy back. Reporter state television showed men with kalashnikovs amid the crowd on a nearby overpass. The deposed president s supporters were accused of doing the firing, but we couldnt tell. What we saw was a stream of motorbikes acting as ambulances for the dead and injured, and angry egyptians accusing their military leader of murder. Sisi, you are a killer you are a killer sisi we will kill you we slaught you reporter a few hundred meters from the square, the crowd was desperate to show us a mosque transformed into a hospital. Everywhere we looked, frantic attempts to keep the injured alive. This is how todays socalled march of anger called by the Muslim Brotherhood has ended. We counted 12 dead during our visit, but that figure has more than doubled since. And while some helpers ferried in tanks of oxygen, others ferried the bodies away. We havent expected the guns again. We are trying to get our inaudible , and they are shooting us again. I dont know why. Reporter parts of cairo are echoing with gunfire tonight, and dozens have been killed. The outside world has again called for restraint, but right now there seems no exit from egypts deadly spiral of violence. Woodruff the violence also spread again to other cities in egypt. Our second report is narrated by Lindsey Hilsum of independent television news, and, again, it contains some graphic images. Reporter Muslim Brotherhood supporters marched down the corniche in alexandria, where the movement is traditionally strong. They carried a banner of general sisi, egypts de facto leader, with an israeli star of david. Traitor, they cried. Leave, leave, they chanted at the government, waving pictures of their ousted president Mohammed Mursi and shouting that they were ready and willing to be martyred for their cause. translated the Security Forces are doing what the mubarak regime did burning churches and blaming it on the brotherhood. Reporter earlier in the day, soldiers in Armored Vehicles patrolled the corniche. Brotherhood supporters had burned down the judges club overnight. They see the judiciary as enemies, too. Some of the worst violence occurred in ismailia, where brotherhood supporters walked straight up to Armored Vehicles. The pictures are upsetting. The soldiers showed no mercy. They shot to kill. The young men braved small arms fire, shouting, were peaceful. Some ran away as bullets pursued them, but others went straight into danger to rescue their comrade. Is this the face of egypt from now on . Youths roaming alexandria, setting tires on fire, turning a ramshackle resort into an urban wasteland. And ismailia, the city of beauty and enchantment where the brotherhood was founded a war zone where citizens fight the army as the nation descends into disaster. Brown the days developments prompted protests elsewhere in the muslim world, as well, against the crackdown in egypt. Thousands of people gathered in istanbul, turkey, condemning the violence in cairo. They waved images of Mohammed Morsi and chanted their backing for the Muslim Brotherhood. In pakistan, crowds in karachi also criticized the egyptian regime, and they attacked what they called u. S. Support for dictators in the muslim world. But in saudi arabia, King Abdullah endorsed the actions of egypts interim leaders. He called it a fight against terrorism. We get more on the situation in egypt now from Nancy Youssef of mcclatchy newspapers. Shes in cairo and spoke with us a short while ago via skype. Well, nancy, welcome. Youre under a curfew now,in, but what can you tell us the latest about whats going on around you there tonight. Well, most of the country is relatively quiet, compared to this morning when there were street fights all over the country. And most what were seeing now is activity in the sinai. There are some buildings on fire here. And theres a lot of anxiousness, if you will, in the country as the Muslim Brotherhood has said theyd like these protests to continue for another week, which portend more violence and more instability. Brown well, thats what i wanted to ask you about. Really no signs whatsoever that theyre backing down at this point that they are calling for continued rallies . Is there any debate within the Muslim Brotherhood that you can discern about what should happen next . No, in fact, we talked to some of the leadership within the brotherhood and they said they cant back down because to back down would be to acquiesce to military rule which, from their perspective, was one of the things that the 2011 uprising was supposed to end. And, also, frankly, they have no incentive at this point to back down in the sentence there are no negotiations going on. Theres nothing for them to gain in the sense of political participation, and so for them its all or nothing. And frankly, they have the advantage of eye lot of people, brotherhood members and sympathizers like whong they have been wronged in the last week and i think theres an interest from their perspective to take advantage of that momentum and really try to get back some of the ground that they lost on july 3 when the military force, mohamed morsi, who is a Muslim Brotherhood member, to step down from the presidency. Brown what about the regime . In addition to what theyre doing in the streets, how are they trying to rally public support . What kind of rhetoric are they using . Its incredible the amount of rhetoric theyre using. There are simple things of having pictures of general cece, his posters hanging all over the country, on state television, every channel has a graphic in the corner that says egypt fighting terrorism referring to those who support mohamed morsi. There areemts coming outom themt from them saying purporting to show the brotherhood attacking them, setting churches ablaze, shooting on to the police. There are funerals that are televised, Police Officers allegedly killed by the brotherhood. And so theres a very active Media Campaign to convince and show the public that they are in fact defending the state from people who threaten it, not the other way around. Brown you know, i noted in the piece you wrote tonight for your paper, you said, for the first time friday, egyptians spoke of potential civil war and asked how their nation compared to algeria. Its really getting to that point from people youre talking to . Yes, because theres no room for negotiation for either side. Nobody is talking about finding a settlement. The negotiation effort that were led by deputy secretary of state bill burns and the european union, and local intlockatures here failed. And in those negotiations they couldnt agree on minimal things, so both sides seem to think they have the moral high ground in this battle. So you are starting to hear people refer to the other side as them, and us versus them. People are asking, are we going to be like algeria, which also erupted in civil war in the 90s when after the first round of elections, in some the islamist ones were canceled, so their islamists didnt even get to office when that war broke out. It was quite ugly and went on for years. Youre starting to hear concern egypt is headed on this path between the rhetoric, the divisive nature, and the number of deaths. These are deaths that havent been seen here ever. The deaths that weve seen in the past 72 hours are more than all those killed during the 18 days of the 2011 uprising that led to the fall o of hosni mubarak. It is spurring worry among everyday egyptians about where the country is headed. Nancy youssef, thank you. Thank you. Woodruff still to come on the newshour overreach at the n. S. A. ; a planethunter goes dark; opening up a pristine rain forest to oil drilling; shields and brooks on the weeks news; plus, harper and musslewhite on playing the blues. But first, the other news of the day. Heres kwame holman. Reporter the number of dead in thursdays car bombing in beirut, leban, went up at least 22 today, with more than 300 wounded. It was the deadliest attack there in nearly three decades, engulfing a busy street in fire and smoke. The site is near a complex where the shiite militant Group Hezbollah holds rallies. Today, the groups leader, Sheikh Hassan nasrallah, blamed sunni radicals. He pledged to double the number of hezbollah forces helping fight sunni rebels in syria. A sudden wave of refugees from syria is pouring into northern iraq. U. N. Refugee officials reported today that many come from aleppo, syrias largest city, and their numbers approach 8,000 a day. Theyve been crossing at a new bridge over the tigris river. There already are more than 150,000 Syrian Refugees registered in iraq. Wall street ended a tough week on a down note. The Dow Jones Industrial average lost more than 30 points to close at 15,081. The nasdaq fell three points to close at 3,602. For the week, the dow lost 2. 2 . The nasdaq fell 1. 6 . Bert lance, who served as budget director for president jimmy carter, has died. He passed away last night at his home in georgia. Lance was a carter friend and political ally who headed the National Bank of georgia. He went to washington in 1977 to take the budget post in the new carter administration. Within a few months, he was forced to resign his position amid a banking scandal, but he ultimately was cleared of wrongdoing. Bert lance was 82 years old. Those are some of the days major stories. Now, back to jeff. Brown the National Security agencys eavesdropping programs were back in the news today. Margaret warner has the story. Warner for weeks, president obama has said the n. S. A. s informationgathering on americans was strictly limited and tightly overseen by the foreign Intelligence Surveillance or fisa court. But today, the Washington Post reported the spy agency has overstepped its Legal Authority thousands of times each year since Congress Expanded the agencys powers in 2008, and the fisa courts chief judge told the post his court doesnt have the ability to independently verify if the spy agency is complying fully with privacyprotection rules. The report was based on documents leaked by former n. S. A. Contractor edward snowden. Washington post correspondent Carol Leonnig worked on both stories and joins me now. Carol, welcome. Thank you, margaret. Warner first of all, what, sort of information has the n. S. A. Been collecting and storing on americans that is beyond the scope of the law or the court rules . The courts rules are very strict on several things, but the most important is not intruding on americans privacy when there is no reason to suspect that they have some link to terrorist organizations or are in communication with foreign powers. And the violations that are documented in this memorandum from the n. S. A. Remember, were only seeing a partial window were seeing what the n. S. A. Headquarters reported in a years time, not what all the other n. S. A. Satellite offices offered, but in those instances they broke some of the privacy rules, and they broke some other rules that have to do with foreign intelligence gathering. The most striking probably r example that people are taken by is that there were a series of phone call records stored from the washington, d. C. Area code zip code, forgive me, and this was a glitch, essentially, because a switch missed read 202 for 20, which is the country code for egypt. We are allowed to collect a lot of records about foarp communications, but when you start collecting a lot of washington, d. C. Phone records, its another story. Warner now, had these violations been reported to the court,aise gather they are required to . Its incliewr from the document because its really an n. S. A. Internal audit is how many of these were reported to the court. A portion them should have been that have to do with fisa authorities, when youre looking into americans records and we honestly dont have the rest of the chain ton what was reported. What we coknow is there are thousands of them and the Obama Administration has assured us and the public before this came out that it happens infrequently, once in a while. Warner now, equally startling was your companion poos, what the District Court judge, Reggie Walton, said to you about the fisa Courts Authority when you asked him about this. Explain that a little more. So hes the chief judge of the secret spy court, the foreign Intelligence Surveillance court, that is supposed to be the lynchpin for the checks and balances on our government spying programs. It takes it really seriously. It does everything in a classified, secret skiff, but its a diligent careful court. What he essentially said was there are practical limitations on what we can do and we must trust the government to report to us these violation because we cant independently, with our resources, ferret that out. Warner and why cant the court fer theatout, verifying the information independently . Well, there are the obvious issues of resources. I mean, this is a court with a number of judges who all have plenty of busy dunkin donutses themselveses Reggie Walton has a very busy docket himself and they have a very busy staff. Soso those lawyers receive the information from the compliance allegations, and they elevate to the judge if it warrant it it and thats a very practical reason why it would be impossible to be policing and looking behind the government when they report thousands of violations. Warner now, doesnt this compliance or violations of compliance information also have to be reported to congress, and what the department of justice . It does. Warner do they verify it . Congress has a lot more in the way of staff for reviewing. Do we know to the agree which they look over it . We dont. I did find it interesting last night when we asked senator feinstein for her comment, ands you know, senator feinstein has been a pretty arch reporter warner a member of the intelligence committee. Exactly, and a very strong ally for the government and n. S. A. In supporting these efforts. She said that she feels the subsector, subsection of violation thereas she doesnt have authority over, she should now perhaps Gain Authority to review some of those that have to do with foreign communications. Warner now, what was the reaction, both from the administration and also on capitol hill . Theres been a lot of reaction. Initially, the white house was not commenting for our story. The n. S. A. I noticed this morning
