centcom's intelligence operation was anything but unified. critical assessments of the iraqi security forces were regularly being altered by top intelligence brass. words like "slow," "stalled," and "retreat" changed to

"deliberate" and "relocated." which had the effect of painting a rosier picture in final reports delivered to general austin and his staff. but it didn't stop there. in one instance centcom's director of intelligence, major general steven r. grove, blocked a negative assessment of iraq's military from the president's daily brief, a top-secret intelligence summary viewed only by the president and his closest advisers. on february 19th, 2015 the pentagon's defense intelligence agency concluded iraqi security forces wouldn't be ready to retake mosul, iraq's second largest city, before the end of the year. in tampa centcom's iraq analysts agreed. but according to sources, general grove ordered the assessment kept out of the president's brief until after his boss, general austin, testified to congress about the

iraqis' progress. >> isil is losing this fight. >> reporter: making the case for an additional $715 million for the program. to stall the negative assessment from getting to the president, centcom senior staff asked for revisions. >> we're about where we said that we would be in the execution of our military campaign plan. >> reporter: and on march 3rd austin told congress the "train and equip" strategy was working and that isis was on the run. >> the fact is that he can no longer do what he did at the outset, which is to seize and to hold new territory. he has assumed a defensive crouch in iraq. >> reporter: last fall, after the pentagon began its investigation into allegations of intelligence manipulation -- >> i don't want intelligence shaded by politics. >> reporter: -- the president laid out his expectation that intelligence never be distorted. >> we can't make good policy unless we've got good, accurate, hardheaded, clear-eyed intelligence. >> reporter: general austin

retired earlier this year as centcom commander, but in a statement to cbs news he said he never directed anyone at centcom to adjust or delay intelligence, nor would he have tolerated such actions. his director of intelligence, general grove, declined to comment. he was rotated out of centcom this past may. the inspector general's investigation, scott, is ongoing. >> jim axelrod, thanks. coming up next, a massive e-mail breach at yahoo!. and later, honoring the man who gave us the motown sound.

for many the shootings in tulsa and charlotte are proof of police bias. but research confirms it's not just the cops. here's dr. jon lapook. >> most people are biased. according to our research, the majority of americans show some degree of unconscious negative attitudes towards minorities. >> reporter: nyu psychologist david amodio studies the science of racial bias and prejudice. in this test subjects are shown a picture of a black or white male carrying either a gun or a harmless object and must make a quick decision to shoot or not shoot. >> and now you are in the role of a police officer and what's been found is that if the person who appears is black and they're holding a cell phone or a soda can people are more likely to

accidentally shoot them than if they were white. >> reporter: one study found subjects were about 30% more likely to shoot an unarmed black person than an unarmed white person. >> when we've used eye tracking in that task, what we find is that the eyes always go to the person's face first and then tracks down to see what's in their hand. >> reporter: so they see their color first. >> yeah. >> reporter: and they may make a biased decision based on that. >> and it's automatic. it happens within 100 or 200 milliseconds. >> reporter: can you be trained not to automatically look at the face? >> we tested that strategy in the laboratory and we found it's effective in reducing bias in shooting. >> reporter: in the lab focusing on the object rather than the race reduces mistaken shooting of unarmed blacks by as much as 45%. >> oftentimes we need to make a snap decision, and it can take effort and some time to overcome an automatic bias. >> reporter: one big question is how research like this in the controlled setting of a lab applies to real-life situations in the field where so many unpredictable things can happen.

>> announcer: this is the "cbs overnight news." welcome to the overnight news. i'm don dahler. history will be made tomorrow in washington with the grand opening of the smithsonian's national museum of african-american history and culture. three days of festivities kick off today with what they're calling a homecoming. music, song, poetry, and storytelling. the museum sits on the national mall right next to the washington monument, and it's designed to celebrate america's shared history of politics, sports, and entertainment. gail king and norah o'donnell got a tour from the museum's founding director, lonnie bunch. >> on the mall it's mainly white marble. and i thought, could we do something that gave a little

color to this? >> in more ways than one. >> well, and that's when i realized. >> reporter: wrapped in bronze and inspired by the three-tiered crowns used in west african art, the national museum of african-american history and culture shines brightly near the center of the national mall. >> this is a cabin from edisto island, south carolina -- >> reporter: but to get a sense of the african-american experience you have to go below the surface, five stories down. >> at its peak it would hold between 8 and 16 people would be in that cabin. >> reporter: a cabin for slaves and shackles small enough to restrain a child, reminders of america's regretful past. while a stool from a greensboro, north carolna lunch counter represents a resolve to move beyond segregation. >> what i see is something very simple. sitting in a chair is transformative. >> reporter: this museum will challenge your emotions. tears will be shed here. but there's joy to be found too. >> i've got to say, this is

cool. >> reporter: like chuck berry's cherry red cadillac. >> did you sit in the -- >> you're supposed to treat artifacts with respect. but of course i sat in there. $$what, are you kidding me? >> reporter: about 40,000 artifacts have been collected. the fact that less than 10% of it is on display is emblematic of the pride and dedication that made this museum a reality. >> so i'm very humbled. i think in some ways my biggest worry was could we find this stuff. >> reporter: after president george w. bush signed legislation to create the museum in 2003, congress designated 270 million, or half of what it would cost, to build it. over 300 million more came through fund-raising efforts, while corporate partners, business leaders, and celebrities were the top donors. ♪ 4 million came from people giving whatever they could afford. like the million dollars pledged by the congregation of the alfred street baptist church in alexandria, virginia. >> the church tried to emphasize that every gift mattered and wanted every member to believe

that no matter how large or small your gift you're making history. >> people are going to be able to leave their stories behind. ultimately their picture and their story will be here. >> reporter: visitors can add their history too. using an interactive display. but the newest smithsonian museum is not a time capsule. it's a place where you will be encouraged to explore current events, including the complicated conversations of race that continue today. >> the museum cost a half billion dollars to build, and much of that came from hundreds of thousands of small donations. time lapse video captures the building's construction. the groundbreaking took place nearly five years ago on the only vacant plot of land on the national mall. the final piece of steel was installed just last year. the bronze-colored facade is made up by more than 3,500 panels. architects phillip freelon and david ajay discuss their creation. >> we felt the weight just about every day. because we knew that we were

building something not for the next ten years but the next 100 years that would represent our culture. >> the museum is not just about making any shape just for the sake of it. it really tries to make from the very silhouette a story for people to ask why. and it really tries to bring you back to central and west africa so you think about the kind of empires of that time and the history that the african-american community have. but also that the geometry like coming to america, it defers to the monument of washington, 17 1/2 degrees, to show how it's integr integral. even though it's a different place, it's part of the same place, it's part of this place, america. >> in many ways it's going to be there as a reminder of the importance of this institution because of its location. literally within the shadow of the washington monument. >> it's taken 200 years to complete this master plan, and last but not least i think this museum completes it. makes you understand what the founding fathers were trying to

achieve with this motinotion of palaces of culture to educate the people. and i think this museum comes at a very opportune time to finish this master plan and to send it into the future. >> the museum faced both funding troubles and political battles. jan crawford has that part of the story. >> it gives me goose bumps to see it happening. >> reporter: it's been a long road. and the story of this museum like the african-american experience is one of trial and triumph. >> to see it finally happen after all this time is just really overwhelming. >> reporter: it was a century in the making. a dream for generations. it became reality through tireless work by people like judge robert wilkins, who helped build coalitions so the full story could be told and shared for generations to come. the effort goes back to 1915, when black civil war veterans, their contributions to winning, their freedom ignored, pushed for a memorial to honor their service. funding never came. >> this has been one of the

great days of america. >> reporter: decades later civil rights movements swept the country. reigniting the effort to recognize african-american history. but the road blocks seemed almost insurmountable. civil rights icon congressman john lewis introduced 13 different bills to create a museum. opposition came from multiple fronts. >> once we approve this museum, we will be called upon by other minority groups, and they will be justified in doing so. to provide museums for their particular groups. >> so many said why do we need a special place to tell those stories? >> reporter: jeanetta cole serves on the museum's scholarly advisory committee. >> when there isn't an acknowledgment of a people's history and their culture. there's no acknowledgment of those people.

>> reporter: another obstacle, federal land use groups argued against another building on the national mall, which they considered overcrowded and pushed for a different site on the edge of the city. >> it would be appropriate to place a monumental building on this site. >> reporter: judge wilkins was part of the committee that urged congress and then president george w. bush to build the museum on the national mall. >> i think that symbolically it's very important because the history of african-americans had been you were in the back, you had to enter a white person's home from the back door. >> reporter: will kukins was th when the president signed the museum bill into law in 2003. museum director lonnie bunch then began the difficult task of raising $270 million in private donations and collecting the thousands of artifacts needed to fill such a large space. in 2012 crews finally broke ground. >> it's amazing what we've gotten here. it's amazing we've gotten here. >> a miracle. >> it is.

and i don't think that that's overstating it. it is a miracle. >> reporter: jan crawford, smelled like yoga-aroma. i'd wash them, and it'd be back before i even got to class. finally, i discovered new tide odor defense. it eliminates the yoga aroma. so i can breathe easy hummmmm. don't just mask odors. eliminate them with new tide odor defense. if it's gotta be clean, it's gotta be tide. i'll take it from here. i'm good. i just took new mucinex clear and cool. ah! what's this sudden cooooling thing happening? it's got a menthol burst. you can feel it right away. wow, that sort of blind-sided me. and it clears my terrible cold symptoms. ahh! this is awkward. new mucinex fast-max clear & cool. feel the menthol burst.

and clear your worst cold symptoms. start the relief. ditch the misery. let's end this.

lonnie bunch is the founding director of the national museum of african-american history and culture, which opens tomorrow in washington. bunch felt the museum would not be complete without a slave ship. but it turns out the only place to find one was at the bottom of the sea. scott pelley joined his search for "60 minutes." >> reporter: mozambique island defies the erosion of time. the portuguese colonists who claimed it 500 years ago would still find the cut of the cloth that borrows the wind, as familiar as the cut of the stone that framed their city. ♪ lonnie bunch came to this capital of the slave trade because he was determined to

launch america's new national museum on the remains of a ship. >> i thought it wouldn't be hard. so i called museums around the world and said, okay, look, you must have some things. you must know where i can get some material. and everybody said no. and they said to me, lonnie, almost every slave ship was at the end of its life so, it's probably at the ocean floor. and then i got scared. thn i thought, well, i'm not going to be able to find this. >> reporter: mozambique island rises from the indian ocean, south of the equator. it was one of the points in what was called the triangular trade. goods from europe to africa, slaves to the new world, and cotton, gold and tobacco back to the old. in the 1400s the portuguese were the first europeans to trade in slaves, and they became the largest. followed by the english, french, spanish and dutch. on mozambique island the portuguese built a fortress that they called st. sebastian for

the christian martyr who was captured, chained, and murdered in rome in the year 288. the irony of that name was the only thing here the portuguese failed to grasp. >> you know, when you look at the enormous effort that went into building this fort, they were protecting something that was hugely valuable to them. >> they recognized that the key to their future as nations was economic prosperity, was the slave trade. >> reporter: the fort oversaw the trafficking of more than 400,000 slaves. bunch was certain there had to be evidence of a ship. and he soon discovered he wasn't the only one looking. >> give me a hand. >> reporter: he found a group of researchers calling themselves the slave wrecks project. and they were following a promising lead. >> what do we find down here? >> a very interesting thing. >> reporter: desio mwanga is a mozambiquan ark yol gist helping

the slave wrecks project locate beginning of the story. >> this was a tunnel that was used to put slaves inside the island or put them out of the island as well. >> reporter: under the old portuguese town tunnels connected holding pens to the sea. the devout portuguese preferred to keep slaves in transit out of sight. how were these slaves captured? >> some vijindividuals, african individuals, specialized in capturing slaves. they'd go and raid villages far, far from here. and they'd walk chained all the way from there to here. and of course lots of them died on the way. >> reporter: so these were africans capturing africans. >> yes. it was not only a business for the portuguese, but also for some of the local chiefs as well. >> reporter: those local chiefs came to this auction house to sell captives to european clients. >> a male in the late 18th century, early 19th century, would go anywhere from 600 to $1500, which is probably about,

oh, $9,000 to $15,000 today. >> reporter: this was incredibly lucrative. >> in the years before the civil war the amount of money invested in slaves was more than the amount of money invested in railroads, banks, and businesses combin combined. this was the economic engine of europe and the united states. >> by the time you got here -- >> reporter: the enslaved marched from the auction house down this ramp and onto the ships. >> what you probably had was almost an assembly line. you'd bring people, you'd sell people. then you would move them onto the boats and off to the new world. >> reporter: what does black america need to hear in your estimation from the echoes off these steps? >> i think all americans need to recognize that as tragic and horrible as slavery was, as big an economic shadow as it cast, the one thing it didn't do was strip people of their humanity.

and i wish that all of us were as strong as the people that walked down those steps and got on those boats. >> we're wading out into the tidal flats. >> reporter: if lonnie bunch was to find his slave ship, he would need steve lubkemun, co-founder of the slave wrecks project. he's an anthropologist from george washington university who believes that slavery is the greatest story in maritime archaeology. >> think about the way in which computers nowadays affect all of our lives. it's not just -- it doesn't affect just the computing industry. everything is interlinked and depends on this. and the slave trade in its time was truly the equivalent. it reached into and influenced and created the modern world. >> reporter: even so it's not likely much has survived centuries under the sea. >> we're not talking about a hull you're going to find down

there and masks and all of that that you would imagine in your mind's eye. >> we don't find intact ships. we find parts of ships. you have to go underneath the water, add some difficulty to this, find the pieces, try to put them back together, and put together the story that you can. >> reporter: the story lubkemun was searching for wasn't discovered underneath the water. his ship was lost in the dry official records of capetown, south africa which reached back to the 1600s. the slave wrecks project had been diving into these binders for months when they discovered the "st. joseph," known in portuguese as the "sao jose." the "sao jose" arrived at mozambique island in 1794. the cargo manifest records 1,500 iron bars for ballast and more than 400 slaves bound for brazil. this is a cargo sketch from a

different but typical ship. paul gardulo is a historian of slavery and curator of the smithsonian museum. >> bodies and souls laid side by side with no room to move, no sanitation. many people on these voyages died. >> reporter: how long was that journey? >> a journey like the one the "sao jose" took could take up to four or more months. >> reporter: this is slavery on a global industrial scale. >> from about 1500 through the 19th century, through the late 1800s, we're talking about at least 12 million people who were taken from their homelands across the sea. many, many hundreds of thousands more, untold people, were lost during that trade. >> reporter: off capetown, south africa the captain of the "sao jose" was caught between a

violent storm and a nautical chart spiked with warnings. whittle rock, bellows rock, rocky bank. the "sao jose" crashed. 212 slaves were killed. and because money had been lost, there was an investigation. >> they wanted to have independent verification. >> reporter: interviews with survivors have survived. >> this is the crew's account. and right here we have the captain's account. and he signed his name here 220 years ago. >> reporter: incredible. >> he said he decided to save the slaves and the people. the people are the crew. the slaves are just cargo. >> reporter: the 200-year-old investigation pinpointed the site. and in 2010 divers responding to a metal detector discovered bars of iron. one of those divers is jacob boshoff, an archaeologist with

south africa's ezekiel museum and lubkemun's partner in founding the slave wrecks project. he says these are the iron bars we mentioned a moment ago on the "sao jose" manifest, the ballast for the ship. >> so you actually were excavating the sand on the sea bottom. >> that's correct. >> reporter: this stuff was under the sand. >> under the sand. >> reporter: you're in how much water? >> five meters of water. >> reporter: about 15, 20 feet of water. and these are two feet under the sand below that. >> that's right. >> reporter: turns out shallow water only makes the work harder. surf tosses the divers, and sand vacuumed away settles back within hours. but after more than 300 dives this is what they've recovered so far. >> this is the little nails that -- >> reporter: these are nails that pinned sheets of copper over the hull for protection. >> as you can see -- >> reporter: what looks like a lump of concrete is marine growth on a wooden pulley block, similar to this one used to

hoist sails and cargo. this x-ray shows the two white spaces where rope was threaded around the wheel. the divers discovered wood that a lab would later trace back to mozambique. and this may be the most revealing artifact of all. masked by two centuries under the sea. x-rays show a shackle, similar to this, used to bind slaves. to this, used to bind slaves. >> you can see the full report today you can do everything in just one click, even keep your toilet clean and fresh. introducing lysol click gel. click it in to enjoy clean freshness with every flush. lysol. start healthing. ♪ yeah, click

economy or have low yerm igss. >> reporter: aaa looked at cars with v-6, vchlts-8 and 4-cylinder engines and found no benefit to using a higher level of gas than what was called for by the manufacturer. aaa estimates 16.5 million drivers misfueled their cars by upping the octane unnecessarily last year, costing them an extra $2.1 billion. only about 16% of vehicles on the road require premium gas. they are typically high-performance or luxury cars. another 10% run best on mid-grade. while 7 in 10 cars on the road only need regular. >> consumers if they stick with what the owner's manual recommends, they're going to be fine and save some money while they're at it. >> reporter: now, if you're just devoted to your premium gasoline, it's not going to hurt your car. it's not going to hurt your performance. you're just not going to see a whole lot of benefit out of it for most drivers. now, we talked to the american petroleum institute. they represent the gasoline industry. they agree, most vehicles run
