( gunfire ) ( sirens ) >> sreenivasan: a barrage of gunfire-- the wail of police sirens; signals that downtown dallas had morphed into a combat zone. the shooting sent hundreds of people running for their lives. they'd been peacefully marching

against fatal police shootings in minnesota and louisiana. >> they just started going off. i mean just, pow, pow, pow, pow, pow. and then everybody started running, everywhere. as we were leaving, we heard the automatic fire. danananana! the back-to-back fire. it just was wild. >> somebody's really armed to the t! >> sreenivasan: the horror, seen on cell-phone video, was quickly up on social media, for the world to see. a gunman was spotted, shooting a rifle at police from behind a pillar. ( gunfire ) later, officers cornered a suspect in a nearby parking garage. after four hours of failed negotiations, police detonated a bomb on a robotic vehicle, killing the man. dallas police chief david brown: >> he said he was upset about the recent police shootings. the suspect said he was upset at white people. the suspect stated he wanted to kill white people, especially white officers. >> sreenivasan: investigators identified him as micah johnson of mesquite, texas.

he had served six years in the army reserve, with one tour in afghanistan. he told police he acted alone, and organizers of the dallas protest said they had never heard of him. the "black lives matter" movement issued a statement on its main twitter page, saying it "advocates dignity, justice and freedom. not murder." authorities initially said three suspects were in custody. they gave no other details as the day went on. meanwhile, much of downtown dallas was cordoned off as a crime scene, although officials did allow a prayer vigil. and, police chief brown appealed for support, and unity. >> all i know is that this must stop. this divisiveness between our police and our citizens. we don't feel much support most days. let's not make today "most days." >> sreenivasan: until last night, the dallas police

department had the fewest number of officer-related shootings of any large city in america this year. but the city that's home to nearly 1.3 million people is now rattled, and many are wondering what comes next. some of those concerned residents were at elaine's kitchen in south dallas. >> you never know what kind of police is going to pull behind you. and the same way, you know, i don't know what's on the mind of anybody that wants to cause harm to a police officer. >> for some people, they see things what's going on in the world and think, i guess, they can take it into their own hands or retaliate, but of course violence isn't the answer. >> sreenivasan: dallas mayor mike rawlings called for calm today, and he vowed greater protection for police in the future. the dallas killings echoed around the world, as well. president obama got the news in poland, at a nato summit: >> there is no possible justification for these kinds of attacks or any violence against law enforcement. the f.b.i. is already in touch with the dallas police, and anyone involved in these

senseless murders will be held fully accountable. >> sreenivasan: in washington, democrat john lewis of georgia, and the congressional black caucus, made an appeal for reconciliation: >> i really believe that we must come to that point in our country where we respect the dignity and worth of every human being. we can do it. the leaders must lead. >> sreenivasan: and, attorney general loretta lynch also sought to reassure the country, after the tumult of recent days. >> do not let this week precipitate a new normal in this country. i ask you to turn to each other, not against each other, as we move forward. >> sreenivasan: elsewhere, protesters did stand united last night, marching peacefully in new york city, chicago, and philadelphia to demand justice for black victims killed by police. there was even one in

washington, d.c. last night before we headed home and streamed on facebook live. >> woodruff: hari, i know you have been learning more this evening about this sniper, this gunman. what have you been able to learn? >> sreenivasan: we knew the 25-year-old had been in the army reserve. we know during the day he had a tour in afghanistan. what worry also learning is, according to police, he had been plotting this for quite some time at his home they found a detailed combat journal, bombmaking material, ammunition, rifles. this is according to the police chief today. again, they don't think there are any known ties to international organizations or even black nationalist organizations, but this is a picture that will unfold more in the next couple of days. i know you've only been there today but how is your sense of how the community is dealing with this and what are you learning about the relations between the people and the police force? >> sreenivasan: you know, i used to live here for a few

years back when i worked for another network, but one of the things that was interesting is this was a police department that's actually made significant strides in trying to enforce community policing, trying to get in touch with their communities. over the last several years, they decreased the number of officer-related incidents of violence, they decreased the number of arrests, they decreased the number of complaints of use of force. this is, by all measures throughout the country, this is a force that's trying to do things right. there is actually a greater deal of trust between the dallas police department and the citizens here than there was ten years ago. >> woodruff: which is what makes it so ironic. hari sreenivasan reporting for us from dallas. we thank you. police also reported attacks in three states after the dallas ambush. they said a suspect in valdosta, georgia ambushed an officer who answered a 911 call. both were wounded. a suburban st. louis man critically wounded a policeman during a traffic stop; and in bristol, tennessee, officers wounded a suspect after he fired at them.

the events in dallas drew quick reactions from the presidential candidates. republican donald trump said, in a statement: "it is a coordinated, premeditated assault on the men and women who keep us safe. we must restore law and order." and democrat hillary clinton said in a tweet: "i mourn for the officers shot while doing their sacred duty to protect peaceful protesters." we'll have an interview with secretary clinton, right after the news summary. a sitting member of the u.s. house has been indicted on fraud charges. florida democrat corrine brown and her chief of staff were charged today. the indictment says they used funds from a fraudulent charity to line their own pockets. the money was supposed to fund scholarships for poor students. economic news, meanwhile, was positive. hiring in the u.s. surged in june, after two months of sub- par results. the labor department reports employers added a net 287,000 jobs, the most since last october.

the unemployment rate rose .2, to 4.9%, as more people started looking for work. the jobs news helped wall street finish recovering from the brexit sell-off. the dow jones industrial average gained 250 points to close at 18,146. the nasdaq rose nearly 80 points, and the s&p 500 added 32. in iraq, prime minister haider al-abadi fired baghdad's security chief and accepted the interior minister's resignation, after a wave of islamic state attacks. at least 186 people died sunday in a baghdad car bombing, and an attack last night in balad killed 37 more at a shi-ite shrine. a suicide bomber blew himself up at the shrine's entrance, allowing other attackers to push inside. iraq's top shi-ite cleric blamed poor security.

>> ( translated ): at the beginning of this week, at the end of the holy month of ramadan, isis targeted innocent people and killed hundreds of them. last night, the terrorists targeted the holy shrine. so, if the authorities won't live up to their responsibilities and put an end to such security violations, the terrorists will continue committing crimes against iraqi people. >> woodruff: the attacks come as isis has been losing territory elsewhere in iraq. the number of asylum-seekers in germany dropped sharply in the first half of the year. berlin says 222,000 people have registered so far. the number for all of last year topped one million. since then, balkan nations have largely shut off overland migration, and turkey has curbed crossing of the aegean, in a deal with the european union. and, back in this country, the house passed last-minute legislation to stem the surge in drug abuse deaths, and sent it to the senate. nearly 50,000 people died of

drug overdoses in the u.s. last year, double the figure from 2000. more than half are caused by heroin and opioids. still to come on the newshour: hillary clinton on the dallas police shooting and race relations in the u.s.; nato's largest military buildup in europe since the end of the cold war, and much more. >> woodruff: we return to the events in dallas and the violence involving police across the country this week. and we get the perspective of the presumptive democratic nominee, hillary clinton. we also invited donald trump. he declined, but we hope to talk with him soon. i spoke with the secretary clinton a short time ago. welcome, secretary clinton.

as i talked to you, we're hearing about still more attacks on the police in this country. why do you think it is more than 50 years after the height of the civil rights movement that we're seeing events in this country like what we've witnessed this week? >> judy, i wish i could answer that question. i have thought so much about it, and i'm not sure of all the reasons why we are witnessing this kind of violence, and we've got to look at it broadly. what happened in dallas, what's happening to other police officers in our country is absolutely outrageous. we've got to do much more to protect and respect the police, and we have to do much more to make sure that citizens in our country, particularly african-americans, feel respected and protected by the police. i think we've got to listen to each other. we need a conversation. white people need to be listening to african-americans about what it feels like to live

with, you know, fear and anxiety, to be profiled, to worry about what will happen to their children when they go out to play or out on a date or go for a drive. we have to listen to the fears of our police officers who get up every day and do a dangerous job like the police in dallas who ran toward the shooting when it broke out after a peaceful protest. i'm going to do everything i can in this campaign to try to find common ground, bring people together, and i've got specific ideas about what we can do for criminal justice reform. we need national guidelines about the use of force, particularly lethal force. we need to work with the 18,000 police departments in our country, some of whom are real models and others should be learning from about how they deescalate tension rather than turning a routine traffic stop into a killing, and, of course, we need to investigate the implicit bias that unfortunately

too many of us still have. when it's implicit bias in a police officer, it can lead to an escalating situation. so we've got work to do. certainly our elected officials, our leaders in our communities, but really all of us as americans have a stake in trying to listen respectfully to each other and, you know, likely try to find ways we can contribute to ending this violence that is stalking our nation. >> woodruff: so are you saying you think you could make more progress on this than an african-american president who has made improving race lations a priority of his administration? >> well, i think president obama has done an extraordinary job in trying to explain and provide information to anyone who's willing to listen about the inequities and the difficulties

that are being confronted by so many of our fellow americans. his policing commission that he put together after ferguson, missouri, has excellent recommendations, but not enough police departments have followed them, and i want to put money in the budget when i'm president to make it possible for every police department to implement these important reforms. i think, too, there is got to be a national conversation. it can't be just elected officials. we need people in communities talking to each other. you know, during the primary campaign in kentucky, i had a wonderful experience one sunday morning going to an african-american church, and it just so happened the day i was there, they were being visited by a white church. so you had a mixed choir. you had both preachers addressing the congregation. you had people shaking hands and

exchanging views and talking about their lives. you know, that may sound easy, but it's hard in lots of places in our country, and it needs to happen, not just on sunday. it needs to happen every day. as a white person, i want to make clear that whites have to listen. we have to recognize, you know, many of the fears and anxieties that our african-american, our latino and others in our society feel -- we saw the terrible shooting at the pulse nightclub in orlando, our lgbt friends -- i mean, this cuts across so many of the divides in our country, and it should send a clarion call to every single one of us. we do not want to live like this. we don't want any american living in fear. we don't want our police living in fear. if we want to end that, we're

going to have to work together. >> woodruff: madam secretary, we also want to ask you about the f.b.i. report that came out this week. we heard the director james comey say they were not going to recommend criminal charges against you, but he said that you and your colleagues at the state department were, if his -n his words, extremely careless in the handling of very sensitive, highly classified information. do you believe you benefited from a double standard that ordinary government employees experience one sort of treatment and a different one for you? >> no, not at all. in fact, i think director comey made exactly the opposite point in his long testimony yesterday that those who somehow hoped that action would be taken are the ones who were hoping for a double standard. he made very clear there was no basis for going forward. he also clarified what we said

in his -- what he said in his statement. you know, with respect to the handling of classified material, i take it very seriously, and the 300 or so people with whom i e-mailed on the course of my time in the state department do as well. these are experienced diplomats. they have expertise in handling classified material. they were not careless, and the material that they sent to me, they did not believe was classified. the very, very few examples that director comey pointed to have also been clarified, as he accounted yesterday. the state department said two of the three h he had pointed to were human error, they were not to be classified. so i'm very proud of the work we did over four years, and i'm very proud of our diplomats and other professionals who have to act in real time. they are responding to heads of state, to press inquiries and

they are doing the best they can. i do not believe they were careless. i do not believe that they sent material that they thought was classified and certainly no finding of anything intentional was made after this investigation. >> woodruff: last question. do you think director comey erred in says it was extremely careless? i ask that because one of the arguments you make in your comparison with donald trump is that you as a president would be more competent than he would be in the white house. >> well, i think there is a lot of evidence to that based on eight years as a senator handling a lot of classified material, based on four years as a secretary of state, handling classified material which, in my view, did not include what was sent on an unclassified system and certainly was the judgment of the hundreds of people with experience and expertise who dealt with me.

but, look, i am grateful for the professionalism, the f.b.i. and the department of justice, and i repeat that i made a mistake using personal email, and i regret that very much. but i think if one looks at the totality of my public service and the very difficult decisions that i grappled with from bin laden to the iran sanctions and so much more, people can count on me to do the job that is required. >> woodruff: secretary hillary clinton, we thank you for talking to us on this day. >> thank you very much, judy. >> woodruff: this week's violence, from minnesota to texas, has brought long simmering tensions to the spotlight, sparking a national dialogue on race and policing. jeffrey brown picks up that conversation. >> brown: and for that, i'm joined by three people closely involved with this. malik aziz is the deputy police chief for dallas. edward flynn is the police chief for milwaukee. his force has faced scrutiny and

protests tied to past police shootings there; and michael eric dyson is a writer and professor of sociology at georgetown university. he is the author of "the black presidency," and wrote a piece today for the "new york times" called, "death in black and white." welcome to you all. malik aziz, i would like to start with you. as we start the conversation, can i ask you first, are you able to now to confirm it was one shooter last night in dallas? >> well, all i can really conif i remember right now is we know that it's at least one shooter, and with our investigative unit, who is one of the best in the nation, they're turning over every rock to make sure that the dallas police, as you heard our chief david brown and the mayor said earlier, that they believe it's a lone shooter. we want to make sure. we haven't concluded any investigation. we're just on the surface. right now, we have the one lone shooter and we're going to make sure he is the only one before

we release any definitive totality of statements. >> brown: tell us, commander aziz, your own feelings, the feelings of members of the force about what happened last night. >> well, i can say, extend my heartfelt condolences and heartfelt sympathy to the family, friends, loved ones, my brothers and sisters in blue across the nation and abroad, that our hearts in dallas today are very heavy, a very somber attitude, one of disbelief, and it is one of those days -- i have been in law enforcement 27 years here in the city and county of dallas, and i have never had a day like yesterday. it's a day of days and the worst day of our career and my career and many others and one of the worst in the nation. so our men and women are hurt today, but i must say the outpouring of the residential and business community in dallas, our awesome citizenry,

they have shown why dallas is one of the best cities in the world. they have shown us so much love and support, and so much love and support in the nation and abroad. >> brown: chief flynn in milwaukee, what impact has there been in your force or perhaps other forces from what happened last night? >> well, i think it's a recognition and it's certainly a topic of discussion among our officers of the great conundrum that surrounds american policing, which it is very important for us, more specifically, to protect the rights of the people most displeased with us. we've done that many times here in milwaukee, and that takes place in city after city across the country. dallas is a fine police department, but it's not an anomaly among american big cities, going all the way back to the mid '90s when the clinton administration passed the omnibus crime bill, police reached out to disadvantaged neighborhoods to do our best to create alliances with the

neighborhoods to work with them to create safe environments and that's what we endeavor to do. there is no group of people in america more committed to protecting black lives than america's police officers in our urban centers. we're the one group of people, in fact, that regularly risks our lives to do that. >> brown: michael eric dyson, what impact does what happened last night have on the ongoing discussion of the shooting of many african-americans by the police? >> well, it throws into the bowl that all lives are significant, important and matter. when "black lives matter" says their theme, what they're trying to underscore is there is an historic legacy and pattern that prevailed in this culture that stigmatized and demonized others. when we look at the situation if dallas, the reality is the lives of those police are significant

and matter. they should be taken seriously, we grieve with them in that city and nation for loss of life by a deranged person who sought to execute his vision of justice in the world, and we want the same empathy of the police departments of this nation which do a fine job in many instances to defend the lives of those who have been vulnerable. when police people act with disregard for life and end up targeting one population versus another, when the lethal and ferocious consequences of policing in situations like we've seen this week occur, we want the police, who we defend, who i will defend and say they have a righteous duty and job to do, we also want these police to say this does not represent the best of who we are, this does not represent what our ideals are, so when citizens who are clearly not in the wrong and trying to comply with the wishes of a particular police person who are then killed, we have to

have the police supporting citizens who suggest that that is wrong, even as citizens should stand behind great police people, two of whose representatives we have on the show today, to say this is not the right thing. >> brown: respond to, malik. the dallas police department has been involved in involvement in bringing down the killings. >> community policing and engagement, every police department is built on a strong foundation and endeavored to make it better. there can be no progress unless we make it together. there is no us versus them, it's only us working together. so when we look at things and we must show compassion, any police officer, any police chief who does not show compassion or you don't think he's bothered when

we have to take a life, it is not easy, and we are often in those things because by the very nature of the job, it calls on us to engage, and we want to engage the right way, we want to be accountable. that's why we have police chief and police leaders to make sure that we are responsible and accountable, but we also must endeavor to actually have a coalescing of community and police and realize we're not on an island when it comes to policing. if we don't actually -- if a community doesn't actually demand for a right way to be policed, then you will leave it up to the police to give you our version of policing. that may not be what community actually needs. >> brown: this is also a day in which we've had some talk in social media and elsewhere that the rhetoric against police is inciting violence like we saw last night in dallas. do you see a growing anti-police

atmosphere in the country? >> i think what we're finding on the streets of our cities is a level of license being taken by the offending community to challenge officers on the streets of our most disadvantaged neighborhoods where our efforts are the most important around most requested. i think what we need to do is step back from this binary discussion we're having right now that, on the right hand, we talk about police use of force when it's right or apparently wrong and, on the left hand, we talk about the fact that the greatest disparity of race in america right now is as a crime victim. all right? our central cities, our communities of disadvantage characterized by intergenerational poverty have the highest rates of violence by what we like to call the industrialized society. we're the most heavily-armed, most violent society in the industrialized west. it is our african-american communities of disadvantage that suffer the most from it.

their partners in dealing with it are the police, often placed in difficult or ambiguous circumstances and sometimes do the wrong thing, but overwhelmingly are the community partners. if we're going to have that community discussion, we have to talk about it all at the same time, because the same neighborhoods with the highest rates of violence, havest rates of poverty unemployment, substandard housing and education. we haven't had that conversation in 40 years. we're delegating america's social problems to the police. >> brown: how do we get there? it's extremely important to integrate all those facets together. when we talk about the economic inequality that prevails in the cities, when police are thrown into the caldron, seething as it is, when black or brown people are subjected to force used against them, wean they are policed by people who come from outside their communities, community policing is a grand and great deal, i think the issues of inequality should be

put forth on the table, and the respect for human life, why is it that there is a vicious repetition of pattern in certain communities and not others? we must see each other as human beings. we must acknowledge the difficulty of the job the meese have to do and respect the humanity of those people. when we see this week the tragic loss of life of those police but before that two black victims who did not deserve to die and we would expect the meese to say this is wrong, this is is a scurilous and insensitive thing to police, then they see us sympathize with the police and we can bridge the gulf and address the problems. >> brown: thank you three very much. >> thank you. >> woodruff: next, leaders from

nato countries met in poland to finalize plans to beef up the military alliance. for the first time since the cold war, multinational troops will continuously rotate through four countries in eastern europe. special correspondent nick schifrin, with the help of the pulitzer center on crisis reporting, concludes our series with a look at america's largest military buildup there in a quarter century, and why russia sees it as a threat. >> reporter: here's the scenario: an unnamed enemy has invaded a nato ally. the u.s. response is heavy and swift. for u.s. troops who have been fighting in iraq and afghanistan, this is more firepower than they've ever had. >> oh man-- that ( bleep ) was ( bleep ) wild! >> we've been fighting an insurgency for the last 14 years. now we're prepared to fight someone who is closely matched

to our combat power. >> reporter: captain joel marbut deployed twice to afghanistan. this exercise, held last month, was the largest in eastern europe since the cold war. >> they're prepared for any enemy counterattack to come across the international border. >> reporter: marbut isn't allowed to name that enemy. but in the command tent, lieutenant colonel johnny evans pulls fewer punches when discussing his polish hosts. >> they see examples of russian aggression. us being here, assuring them that the u.s. has not abandoned them, that the u.s. is still a strong supporter of nato, can do nothing but provide additional assurance. >> reporter: on the training ground, there was even a burned- out soviet style tank for target practice. this is not only assurance to allies-- it's also deterrence, and a warning, to russia. ( explosion ) >> reporter: after the cold war, the u.s. military dramatically downsized in europe, from 200,000 to 30,000 troops. now the u.s. is planning to quadruple spending. and it will rotate 4,200-soldier heavily armored brigades back to

back, with their own equipment, at the highest level of readiness. >> that is a powerful capability that will be very effective at changing the calculus for russia or any potential adversary in europe. >> reporter: general ben hodges commands all u.s. army forces in europe. those new american troops are in addition to 700-person nato battalions deploying to the baltic states and poland. we spoke to him during the poland exercise. >> i think a combination of a nato battalion plus a u.s. armored brigade combat team, that's a powerful deterrent. if deterrence fails, now you're talking about a liberation campaign. >> reporter: for the poles, that word liberation doesn't feel farfetched. >> the poles are very nervous, obviously because of world war ii. >> reporter: few polish politicians have more world war ii credentials than minister and senator anna maria anders.

her father was wladyslaw anders, who fought the soviets as poland's army commander. today, this community remembers how during the war, the soviets deported local residents to siberia. >> these people are worried that it will happen again. >> reporter: what convinced them it could happen again? >> crimea. crimea, you know. >> reporter: in 2014, russian soldiers in crimea sparked an annexation from ukraine. it took less than a month. >> it happened so quickly. i think we all have become a little complacent. we haven't had a war in so long in this area. >> reporter: u.s. soldiers are teaching poles military hardware, starting in childhood. >> that's where the trust starts, from that youngest generation building trust. they understand that america is aligned with poland. >> reporter: lieutenant colonel deric holbrook leads the 2nd cavalry's field artillery squadron. part of the polish exercise is visiting small towns like suwalki. soldiers and fathers encouraged kids to become comfortable with guns.

nearby, young baton twirlers entertained the crowd. it seemed like this entire town of 60,000 showed up in support. the next morning, holbrook's men hit the road. they were on a 500-mile drive-- the longest military movement in eastern europe since world war ii. they drove through this 60-mile- wide gap between nato members poland and lithuania. this is the suwalki gap, where nato's notion for collective self defense is perhaps most vulnerable. 30 miles to my west is kaliningrad, a russian enclave. 30 miles to my east-- belarus, a russian ally. if russia wanted to move into this gap, it could most likely cut off the baltic states from the rest of europe, and the rest of nato. that geography is a product of nato's expansion east. in 1949, nato's eastern border was italy. by 1999, it had added seven more countries; by 2009, nine more countries, including the

baltics. suddenly, nato had beachheads on russia's borders. >> i think that if we would discover that there would be russian troops in mexico-- i wonder how many american politicians and american people would think this is an acceptable situation. >> reporter: dimitri simes leads the washington think tank, "the center for the national interest." for russia, nato isn't defensive. since 1999, nato has launched wars in kosovo, afghanistan and libya. each ended in regime change. >> that certainly made an impression in moscow that nato expansion was a direct threat not just to their security, but also to their domestic stability. >> reporter: russia again felt threatened when the u.s. either encouraged, or supported, revolutions in previously pro- russian countries. the final straw was ukraine. >> if ukraine is hostile and joins nato, that would be viewed

by russia as an existential threat. >> reporter: this isn't only the thinking of intellectuals, or moscow elite. >> ( translated ): we are not going to mexico. imagine if russia moved its troops there. >> reporter: vitaliy anatolievich is a cossack commander in the breakaway ukrainian region of donetsk. his forefathers, known as free cossacks, were notorious and feared 19th century horsemen. they fought and died for this land they referred to as greater russia. today, they're training their children what cossacks have stood for, for generations: love of land and church. it's a nostalgia for the days before the soviet union collapsed. do you feel like what you're doing now is trying to restore the power and pride that was lost in 1991? >> ( translated ): of course i feel that. it's a renaissance here. this is pure patriotism.

>> reporter: that patriotism is a pledge to be an irregular force for russia in ukraine, and beyond. they cheer disunity in the european union, because they oppose what they perceive as western culture. >> ( translated ): we don't educate them as they do in europe about gay pride and all that. is that normal? it's not normal. >> reporter: the cultural and military divides within europe are widening. another flashpoint: newly built nato missile defense sites in romania and poland. russia labels them threats, and vows to retaliate. >> ( translated ): if yesterday in those areas of romania, people simply did not know what it means to be in the crosshairs, then today we will be forced to carry out certain measures to ensure our security. >> for russia to say this is threatening to them is a ridiculous assertion. >> reporter: russia would say those missile defense systems can be turned from the middle east toward russia. >> it's extremely unlikely, but if russia ever launched a nuclear- or missile-strike, there would be hundreds of

missiles. so this defense shield that's been installed is for individual-- i mean, it's a completely different scenario. >> reporter: putin's threats are made possible by nearly a decade of russian military expansion. according to one study, if it wanted to, russia could overwhelm nato troops in the baltics, in fewer than three days. is it really deterrence to have a few battalions in eastern europe, when russia has hundreds of thousands of troops across the border? >> um. you make a fair point. certainly, russia has been provocative. they talk about nuclear weapons against sweden, denmark, romania, other countries that's in their exercise scenarios, >> when they feel that they are threatened, they have a tendency to close ranks. putin now has universal excuse. whatever is going wrong in russia, he is blaming it on obama, he is blaming it on nato, he is blaming it on the european union; and most patriotic

russians are-- they feel, "well, perhaps our country is being under tremendous threat." >> reporter: that fuels a cycle of increasingly large exercises and increasingly violent warnings. this level of tension hasn't been felt in a generation. and it's being taught by both sides to the next generation. for the pbs newshour, i'm nick schifrin in szczecin, poland. >> woodruff: next to the analysis of shields and brooks. that's syndicated columnist mark shields and new york times columnist david brooks. welcome to you both. although the show, the program tonight, mark and david, the killings b of two black men by

police and the killing of the police in dollars, what do you make of all this, david? >> well, it's been a crappy week. we've had the killings, we've had both our presidential candidates behaving reprehensibly, and i think we're sort of at a moment where, on the one hand, a lot of harsh truths with being exposed, a lot of people who have been silent are speaking out, and speaking out about violence as we've seen in african-americans, frankly, some of the trump movement, some of the white working class members speaking out. that's all for the good. the question is are we going to speak out with actual dialogue and conversation or drift into tribal thinking? there's been a lot of rancid, overgeneralizations in our society that all african men behind the wheel are dangerous, that all muslims are involved in terrorism, that all cops are somehow at war with communities, and if we can speak in a way that's not tribalistic, that's not making these

generalizations, we can make something out of the current moment, but i'm not hopeful after a bad week like this one. >> woodruff: mark, what do you make out of all this? >> judy, speaking for myself, i was overconfident, overoptimistic in 2008. i thought the original sin of america, of racism, was a time to celebrate, that we had done something remarkable in electing an african-american president, and we did, and that somehow with this terrible chapter that's behind us, the constant in every one of these killings and tragedies this week is race, and i get the feeling almost like 1968, that events are in the saddle. it's not vietnam, there aren't 548 americans dying every week and we haven't had a james earl ray or sirhan sirhan yet to assassinate our leaders, but whether it's zika, istanbul,

orlando, events are in the saddle and things are not going to get better and it's a dreary, political landscape right now. >> woodruff: this is a year where there has been, david, a loft anger in the political conversation. how do the events of the week play into that? >> it's a period of bad feeling. when bad filings happen, walls go up and things close. we're losing a lot of closeness, whether open trade, open people and conversations, some of that's closing, at least the impulses in a lot of society, including n.a.t.o. between eastern and western europe, a lot of walls going up and a lot of candidates proposing walls going up. so when people are in a period of bad mood, then they want to hunker down and protect, and that's the exact opposite from what we need now. let's be frank, it doesn't help that we have an american political debate with basically

one all white party and that just means we fall along very polarized lines, when we fall into the normal default position of politics, that we fall along racially polerrized lines, and we have to acknowledge that's an inherently dangerous situation given everything else that's happening. >> woodruff: are we just not equipped to deal with these issues anymore that we've become so polarized? >> we've become incredibly polarized, if it's not a consequence from the silos that we get our information, i don't have to listen to the other side, i just get my own prejudice and perspective reinforced, but we are at a time of incredible political division made more so by our polarized politics. it is to be a great test in politics. when i first started the business, when you make a statement for your candidate for

90 seconds without mentioning your opponent. that's unthinkable if this election year, when, according to the very respected pew poll, a majority of both secretary clinton's and mr. trump's supporters are basically voting against their opponent rather than for their own candidate, and i think that's a reflection of the condition of our politics right now. >> woodruff: well, if you single out or look at donald trump for a moment, david, he clearly has been saying some things that have brought, i think, co consternation to somed there is enough blame to go around. donald trump was in washington this week, we were told, to try to bring unity to the republican party, to sit down with members of congress who were republican to bring them on board and apparently ended up with meeting with republican senators dissolving into more name

calling. how united is the republican party with one week to go before their convention? >> not at all. he gave a speech earlier in the week, the star of david, mosquito speech, he's always ranting but sometimes he veers into full drunk wedding toast mode. that speech was incoherent in its logic and random and what one senses in him, rising resentment. in that speech, he ripped on cnn, whoever was in his way, then comes to washington and he rips on whoever is not totally loyal to him, whether it's ben sasse, mark kirk, two senators. he's filled of resentment even in the moment of triumph and you see him being more himself than tame and civilized. >> woodruff: do you see more unit in the republican party or less? >> i think there's a forced sense of unity now. him and bill flores, republican

congressman from texas, says that very encouraging that mr. trump is making fewer and fewer unforced errors, and thought that was great progress. i agree with david about the performance yesterday before the republican senate caucus in particular when he took on the senator from arizona and said, you're going to lose this year and, of course, he isn't running this year, john mccain is. they have six-year terms in the senate, i don't know if mr. trump's aware of that. but beating up on mark kirk who is an embattled republican in illinois, very difficult uphill race and, judy, i mean, where was mitch mcconnell, the republican senate leader to stand up and say, wait a minute, you're not going to come in here, mr. trump, i don't care if you are the presidential nominee and attack and belittle and demean the senators whose support you're supposedly

seeking. there is a lack of courage and common decency in the republicans, it seems to me, right now. >> woodruff: meantime, david, the democratic nominee to be as you pointed out had her own bad news this week. as you may have seen, i interviewed her a short time ago for the program and asked her about f.b.i. director jim comey's conclusion that, no, there weren't going to be criminal charges brought but that she and the people around her had been extremely careless in the way they handled confidential information. she said that is not the case, that that's wrong, but, you know, whichever way you look at that, what are we to make of this investigation, of its conclusion? where does it leave her as the presumpt nominee? >> i agree with both sides of comey's conclusion that she should not be charged but that basically the defense she has given us and for all these months was a tissue of lies, that she didn't have one defies,

she sent over 100 classified things, had multiple servers and her staff didn't look at -- some of the things they deleted weren't personal, they were actually business. she's told a series of falsehood and frankly i thought her reaction tonight was a little offtone, a little too defiant when a little humility and contrition would be in order given what comby said, accurately. i don't think it rises to the level of indictable offense but should be sobering, and should be sobering if you love hillary clinton and are a democratic and see someone's claims be exposed as falsehoods so readily. >> woodruff: where do you come down on this? >> i was amazed at her answer. i thought james comby, directorr of the f.b.i., his verdict was

not innocent and deemed her and others very careless in the way they treated confidential information. the "wall street journal" poll asked who do you think is more honest and trustworthy? donald trump not known as an ethical giant in most circles, 41%. hillary clinton was at 25%. a meager margin thought she was more honest and trustworthy than donald trump. it's been a problem, lack of transparency and forthrightness back to the rose firm's billing records some 20 years ago in the white house, and i thought there was going to be a start up of candor offenses, the fact she was doing the interview with you. i think it's time for frankness and acknowledgment that this was wrong, that they were misleading, and to me it's not going to go away.

the advantage she has, and it's an inescapable advantage, the canadian prime minister who ran for reelection in 1972 father of justin trudeau, said it's a bad economy, and the choice, continue compare me to the almighty, compare me to the alternative. and that's true. donald trump is an ego maniac. >> woodruff: the republicans are saying they're going to drive home this email story every day between now and the election. is that smart on their part? >> i think so. i mean, the untrustworthiness is a core weakness. i have to say i think trump manages to commit political suicide on a daily basis and yet doesn't seem to die. my big takeaway from the race so

far is he's only down four points in the national polls. so to me, looking at the way he behaved, this should be a bigger victory for secretary clinton but not showing up that way because doubts about her are nearly as great. >> woodruff: something that has our attention with a lot of sad things this week. mark shields, david brooks, thank you both. >> woodruff: gwen ifill is preparing for "washington week," which airs tonight on pbs, and she has a preview. gwen? >> ifill: hi judy. tonight, we'll bring you the latest on the horrific shootings in texas, minnesota and louisiana, and sum up a week that could be the turning point we have been waiting for in a fraught political year, with reporters from the "washington post," the "wall street
