the average joe can become a scientist. this is the "cbs evening news." >> mason: good evening. i'm anthony mason. the images are graphic. a terrorist in a van mowed down pedestrians today for seven city blocks in a popular tourist area of barcelona, spain. at least 13 were killed, more than 100 others injured. two suspects are under arrest, but the driver got away. debora patta is in barcelona. >> reporter: people ran for their lives screaming as the attacker, driving a white van, jumped the sidewalk and plowed into a crowd of tourists and locals. in his wake, bodies strewn across the pavement like broken dolls. witnesses said he was weaving in and out, aiming for people as they desperately tried to get out of the way. he drove seven blocks before abandoning the vehicle. a passerby frantically tried to

give c.p.r. to an injured man. an american tourist who had just arrived at the popular site said the attackier was driving erratically. >> i heard this just group of people scream. then i looked to my left, and i saw a white van. it looked to me as if he was going left to right, hitting people at the little stands where people were shopping. >> reporter: cobb oxford from south carolina, also witnessed the attack. >> move, move, move! >> the best way i can describe it is all hell breaks loose. i saw a car bumper laying in the middle of the sidewalk, and people scattering in all different directions. i counted six or eight bodies within a block and a half. >> reporter: police arrived quickly, sealing off the area and ushering people to safety as they went door to door searching for the gunmen. stores and subway stations were

shut down. it's the latest in a string of attacks in europe where vehicles are the weapon. last summer in nice, france, 86 people were killed when a man drove a truck through crowds gathered to celebrate bastille day. in december, a truck was driven into a crowded christmas market in berlin. and in the u.k. this spring, vehicles were used in an attack at westminster, london bridge, and fenz brie park. tonight, everything is shut down here in the center of barcelona, on what's normally a very festive part of the city. tourists have already been made, but police have categorically stated they were not driving the van that mowed into pedestrians earlier on today. that person, the driver of the vehicle, is still on the run. anthony. >> mason: debora patta with a terrorist attack in barcelona today. thanks, debora. it was just five days ago that a car was used to run down counter-demonstrators in

charlottesville, virginia. here's kris van cleave now with vehicles as weapons of mass destruction. >> reporter: the police in new york is intended to be a deterrent for a city that saw a car plow into a crowd in times square in may. the driver, believed to be under the influence of drugs and alcohol, killed 22. how do you protectlet sidewalks from cars? >> almost impossible in an urban setting like this. >> reporter: ron hosko is a former assistant director of the f.b.i. who has worked on securing major events, including the olympics and political conventions. >> but i think there is a way, with those high-concentration areas. and we it outside of sports stadiums. we see it in other places. we see it right behind us, where it's a safer pedestrian area and tourist area and citizen area behind us than it is on the street. >> reporter: terrorists have used the tactic successfully. today in barcelona, last summer in nice. those attacks prompted increased security across america at major events like macy's thanksgiving

day parade in new york, and the opening of the national museum of african american history and culture in washington. some office buildings in d.c. have installed permanent pylons aimed at stopping a vehicle. the department of homeland security issued a warning to commercial trucking companies in may that terrorists may look to use, rent, or steal their vehicles for attacks targeting pedestrians. but it doesn't have to be a truck. on saturday in charlottesville, police say james field drove his car into a crowd, killing 32-year-old heather heyer, and injuring least 19 others in a matter of seconds. >> there is no cost-effective way to secure every sidewalk in a major city. there is none. we can harden targets that are high-concentration areas, but we're always going to be vulnerable. >> reporter: barricades like this could be used to stop a car, but they would essentially wall off the sidewalks. anthony, it's an open question if people would put up with that kind of an inconvenience. >> mason: kris van cleave, thanks, chris. fran townsend was homeland

security adviser to president george w. bush and is now our cbs news senior security analyst. fran, there have been at least half a dozen of these in europe just this year, vehiclear attacks. sadly, is there nothing we can do to prevent this? >> well, you know, over the years, anthony, governments around the world have put up barriers in large pedestrian areas to prevent cars from getting into them. but you can't do that everywhere. and any iconic sort of tourist landmark, anyplace where people gather-- restaurants, squares-- you can't protect all of them. and, sadly, the enemy, isis, is taking advantage of that. >> mason: isis has basically said their agents did this. >> that's right. >> mason: what does this say about their-- a shift, if anything, in their strategy. >> i think on that score we shouldn't be all that surprised. as we're constricting, as we're succeeding against them in places lake iraq and syria, they're clearly looking for opportunities to strike back, and it's easier asymmetrically against civilian populations in places like-- and we've seen it-- nice, brussels, paris,

germany. you know, in civilian populations they have a terrorist advantage because we can't be everywhere all the time. you know, it's interesting, the other piece to this is spain was not so worried about foreign fighters. we don't know who did this. they have two people in custody. neither was the van driver. but we'll see whether or not this was foreign fighters which are far more prevalent in places like france, germany, brussels. >> mason: so the dilemma, then, particularly for european nations, becomes identifying who might commit a crime like this before it happens. >> that's right. and we know in the united states, the f.b.i. gets these sorts of leads all the time. it's almost overwhelming. they don't have enough resources, and so they make judgments about who they will cover, who they will follow. and it's very, very difficult. >> mason: all right, fran townsend, thanks so much for being with us. >> thank you. >> mason: president trump condemned the barcelona attack and offered u.s. help. mr. trump is drawing fire, meanwhile, from some prominent republicans. here's margaret brennan. >> there needs to be radical

changes take place at the white house itself. >> reporter: harsh criminal from a prominent member of the president's own party, tennessee senator, manuel bojorquez. >> the president has not yet-- has not yet been able to demonstrate the stability, nor some of the competence that he needs to demonstrate in order to be successful. >> reporter: and this from another republican, tim scott of south carolina: >> what we want to see from our president is clarity and moral authority. that moral authority is compromised. >> reporter: while the president has avoided cameras for the past two days, he has not been silent. today on twitter, he swiftly condemned the barcelona attack and suggested his followers, "study what general pershing of the united states did to terrorists when caught." a reference to a debunked urban legend mr. trump told during the

campaign about american general john pershing's alleged slaughter of muslim soldiers in the philippine. >> what they did was they cut open two pigs and they dumped the bullets into the pigs. and they took the bullets and they stood the 50 men up, and they shot each man. >> reporter: the president's quick response to the barcelona attack was a sharp contrast to the days it took him to condemn a white supremacist who drove his car into a crowd of protesters, killing one and injuring 19 others. today, the president also bemoaned the removal of what he called "beautiful confederate stat use," and said american history is "being ripped apart. "n" a statement, republican senator lindsey graham urgedly the president to stop. "you are now receiving praise from some of the most racist and hate-filled individuals and groups in our country," he said. "please fix this." but inciting racial tension can be politically useful, according to the president's chief strategist, steve bannon, who just days ago appeared on the verge of being fired.

in a series of interviews, he dismissed the far right as "clowns," but said, "if the left is focused on race and identity, we can crush the democrats." the president also lashed out at republican senator jeff flake of arizona and endorsed one of his primary challengers. anthony, next week, the president will hold his own rally out in phoenix. >> mason: margaret brennan with the president in new jersey. thanks. joining us now, john dickerson, our chief washington correspondent and anchor of "face the nation." john, those are pretty strong words coming from the chairman of the senate foreign relation committee bhap do you make of senator corker's remarks questioning the president's stability and competence? >> first, who is senator corker? he is not one of the usual suspects always criticizing the president. he is not by temperament somebody rushing out and saying the sky is falling. but in this instance, he says if the president doesn't solve his problems, our nation is going to

go through great peril. so where there is of this is coming from is extraordinary, and the critique he is making is a thorough one. it's not just something he tossed off. >> mason: he said the president needs to move beyond himself. what do you take that to mean? >> he's identified the locust of the program inside the president himself and the reason that is so damning is this is a critique people have had about crched trump and then president trump, his impulsiveness that made him so popular among his base is incompatible with the office he holds. and so when he talks about the lack of discipline, the lack of stability, those are central elemental characteristics a president has to have. and senator corker is saying that they're not there in this president now. >> mason: so if you are in the white house, how do you take this criticism? >> well, you take the criticism right to the person it's aimed at, which is the president. and there is no amount of staff you can ring around a president to fix these problems. these are problems, as senator coark has identified themselves, that are in the man himself. he calls on the president to have some self-reflection. so if you're in the white house, you have to hope the president

is listening. >> mason: john dickerson, thanks. john will be stephen colbert's guest tonight on "the late show" here on cbs. a new poll shows a majority of americans, 62%, want confederate statues to remain standing as historical symbols. 27% of those polled believed the statues should be removed because they're offensive. manuel bojorquez has more on this from stone mountain, georgia. >> reporter: there's no bigger monument to the confederacy than this towering sculpture on stone mountain outside atlanta, the carving of jefferson davis, robert e. lee, and stonewall jackson is larger than mount rushmore. edward wilson has lived near it more than 20 years. i'm curious though, when you look at it, what do you feel? >> i feel the war continues. >> reporter: though no battles were fought here, it's a tourist attraction that even includes a laser light show. but the mounten is also considered the symbolic birth

place of the modern ku klux klan, which had gathered here since 1915. in 2015, white supremacists reallied here and clashed with counter-protesters. it's why williams and others have now started petitions to remove or alter the monument. >> these images are individuals that lost a war that wanted to maintain slavery, that wanted to maintain a way of life that excluded my people and other minorities. >> reporter: but it's a complicated issue, one unlikely voice for moving past the monument's debate is civil rights icon and former atlanta mayor andrew young. >> i think it's too costly to refight the civil war. we have paid too great a price in trying to bring people together. >> reporter: but in tampa today, opponents of a statue of a rebel soldier said they quickly raised the $70,000 needed to remove it. across the country, more than 100 schools and nearly 500 roads

and highways bear the names of confederates. in total, there's an estimated 1,500 symbols to the confederacy. the great-great grandson of general stonewall jackson spoke to us by phone. >> we're ashamed of the monument but not stonewall jackson himself. we're ashamed because it's an image of white supremacy that-- that, you know, as many people interm rit. >> reporter: back here in stone mountain, some groups are planning a protest on this lawn in front of the carving, a self-proclaimed k.k.k. member made a request for a permanent, too, to burn a cross at the top of the mountain. it was denied. anthony. >> mason: manuel bojorquez at stone mountain. thank you, manuel. coming up next on the cbs evening news, the deadly crash evening news, the deadly crash of the uss "fitzgerald" has cost the skipper his job.

"fitzgerald," two senior officers, and at least a dozen sailors are being disciplined for the horrifying collision that killed seven sailors. it happened in june off the coast of yeap. japan. here's david martin. >> reporter: 35 sailors were asleep this this compartment when the bow of the philippine ship punched a 17 by 13 hole in the "fitzgerald's" hull. the seven sleeping closest to the hole drowned, but 28 somehow made it out alive, even though

the entire space was nearly flooded within 30 to 60 seconds. the navy's harrowing recreation of those terror-filled seconds was put together to answer the one question all the families of the dead had: did they suffer? the answer, not for long. the collision sent sailors, lockers, and televisions flying, with water rushing in on the starboard side, they started yelling, "water on deck," and "get out," crambling for a ladder on the port side. after the initial shock, the report says, the sailors lined up in a relatively calm and orderly manner to climate port side ladder even though they were up to their necks in water by that point. two sailors stayed at the bottom of the ladder helping others up. when those two finally cliemedz out, they stayed at the top of the ladder and reached down underwater to pull two more to safety before they had to retreat to another level to seal the flooded compartment from the rest of the ship. one of the dead, gary rem was

buried wednesday at arlington national cemetery. according to the report, he rescued a sailor trapped under a falling locker. the ship's captain, along with the officers and men on watch that night, are considered to have committed critical mistakes which caused the collision. anthony. >> mason: david martin at the pentagon. thank you, david. and we'll be right back. my belly pain i could build a small city with all the over-the-counter products i've used. enough! i've tried enough laxatives to cover the eastern seaboard. i've climbed a mount everest of fiber.
