>> this is al jazeera america live from new york city. i'm tony harris with a look at today's top stories. the massive security breach at target stores grows even bigger. 100 million americans now affected. >> i didn't know it was going to be this chaotic. >> a chemical spill causing chaos in west virginia. people clearing out store shelves after being told they can't drink, cook or bathe with contaminated water. and 74,000 jobs created last month. a look at the disappointing employment report.

>> the massive data breach at target stores has grown even larger, the nation's second largest discount retailer said more shoppers than previously thought is impacted. it's as many as 100 million americans whose information could be compromised. john terrett is more with what may be the second largest data breach ever. >> this story just keeps on giving but all in the wrong ways. it look at target a was a little off target, pardon the pun, when assessing how many customers were attacked. originally it was 40 million actaccounts, but then they found there was an additional 70 million accounts that was seized taking it to 100 million.

there was some overlap between that figure of 40 and 70. this includes your name, street address, and i got to believe your account number too that's one-third of all of us in the entire country. target will contact those who have been hacked. you can go to wate www.target.c. >> they said: >> now target said that target customers will have zero liability for the cost of any fraudulent charges that crop up

on any of their cards. but in the meantime it took a big financial hit when people abandoned it albeit temporarily just before christmas. in revised guidance to wall street oh for the business' fourth quarter target is now telling wall street there is going to be an over all sales decline of you havely 2.5%. that's a big number because prior to this they would be flat, they were where they were this time last year. times, as you know, are tough for all of us, but they're particularly tough for discoun discounters like target because they take it down to the bones to make money. this hack was not the kind of christmas presiden present thatt and it's ceo were looking for. >> they've had time to work through an investigation. >> what we do know, this is not

geeks. this is not people sitting down in their shorts and flip flops in their mother's basements for a bit of fun. no, this is grand scale organized crime of the worst kind. big teams are doing this, they're good at it and they spend their time working at getting better at it. they could be teams in china, russia or people here at home, say, florida. one little key to the sophisticated nature of this, it took them two and a half weeks to even discover about the first 40 million. now its way more than a month since all this started, and it's taken them all this time to tell us and for them to realize. that's a clue about how sophisticated all this is. >> bottled water is being distributed in west virginia after a chemical spill

contaminated drinking water. the area is under a state of emergency. between 2 and 6,000 gallons of a chemical used into the river. people in nine counties have been told not to drink, bathe or wash their clothes until further notice. jonathan martin is live for us. my understanding here is that nearly 300,000 people have been affected by the leak. what are they doing for water? >> reporter: yeah, a lot of people. a lot of people just waiting and hoping they have enough water to do some of the basic necessities, basic things they need. there are 12 of these tanker trucks that have been brought in, and people as you see here are filling up. we see people coming in with sizable containers because they don't know at this point if they'll be able to use their water tomorrow or if it will will be another few days. people are stocking up on this water as you mentioned 300,000 people in nine counties right now told not to use their water

for anything other than flushing. schools have been closed today. a lot of businesses have been closed. it all came to light yesterday when this company "freedom industries" notified authorities there had been a leak from their company into the elk river. the chemical smelled like licorice or sweet candy, and they found it was the chemical of chm, that could be harmful. the question is how much is in the water and what the risk is. we heard that just a few minutes ago from west virginia's governor. >> one indicator of the water, do not use the water until the order is lifted. at this time i do not know how long the order will last.

yesterday we ordered the company to stop girl flows down to the elk river. this is unacceptable. >> you heard the governor say. they don't have a timeline. it could happen in stages. at this point the president of the water company said they're doing a variety of tests. they're flushing the water out and smelling it and a variety of tests, making sure that the water is available for people to use. it could be a day. it could be several days before people can use it again, tony. >> so jonathan, has a federal probe been launched? >> reporter: well, yes, we know that the department of justice has gotten involved. and the u.s. attorney issued a statement.

they say they're taking this very seriously. the company involved has not issued a statement at this point. they want to know when this happened, and did people--were people notified on time, how did this happen and why did this happen? we're waiting to hear from the company. that's what the federal investigation will center around. >> jonathan martin for us in west virginia. thank you. we have disappointing news about the economy today. the labor department said employers added just 74,000 jobs last month. the economists were expecting nearly three times that amount. the unemployment rate fell from 7% to 6.7%. that's the lowest in more than five years. but the number of people looking for work fell to 62.8%. that's one of the worst numbers in more than a generation. let's bring in nela richardson, senior economist from bloomberg. good seeing you, thanks for being on the program. so what happened in the jobs in

the december job reports? >> there are two schools of thoughts. one is to ignore it. it's a blip on the road, we're on our way to recovery. the second is, whoa, let's pause, maybe we're not out of the problem yet. i'm of the second thought. it's going to be a bumpy road and a false starts along the way. >> the last couple of months the jobs reports, they were pretty good jobs reports. >> from the headlines numbers. remember, what is crucial to remember, the economy is creating a lot of part-time, low-income jobs. even though those headlines numbers look great we have a labor force participation rate that as a at a three-decade low. >> people are just discouraged.

>> they don't have any desire to look for a job because people don't think, the boots on the ground, people in this market don't think there are jobs available for them. that unemployment rate that went down, it's a false picture of what's actually going on in the labor market. >> is this bad report an argument for an extension of benefits for the long-term unmrunemployed that is being ded on the hill? >> yes, absolutely. the strong labor report would complicate the case that we need to extend emergency benefits to long-term uninsured. that makes up 30%, 1.3 million people lost their benefits in december. senate democrats have better data to make that case on the hill. >> come back on the program.

nela richardson from bloomberg. thank you, have a good weekend. not only did the economy add far fewer jobs, the jobs created, well, that was disappointing as well. the lack of good jobs is not just a problem for low-skilled workers any more. plenty of folks with college degrees are finding themselves under employed. patricia is here with more on this side of the story. patricia, good to see you. >> it's good to see you, too. these days a college degree is no guarantee of a job, let alone a dream job. recent college graduates are having the toughest time of getting a foot hold on the career ladder. >> when whitney mcdonald graduated with honors she was optimistic about her job proce prospects. >> i was feeling good. i graduated top of my class, and i was feeling great. >> three years on the 26-year-old has yet to land a full time position in her chosen

field. instead she's under employed juggling two part-time jobs that don't require a college degree. >> since graduating i've been working in a restaurant five nights a week and nannying three days a week. >> reporter: in 2001 34% were under employed. in 2012 that number vaulted to 44%. newly graduates have to compete with unemployed experienced workers. >> there is more demand for skill and education than ever before. that makes it harder on young people, even those with college degree because they have less experience and skill than workers in the labor force for a long time. >> transitioning from the ivory tower has always been a challenge for recent college graduates. but finding a good job has never been harder for them.

>> graduates swelled from 15% in 2000 to 23%. in 2011. >> good to see you. on wall street you might think there is a big sell off with this ugly job report. but that was not the case. the nasdaq closing higher. we will dig deeper into the jobs report and what it means for the economy with ali velshi with "real money." a new twist in the events utah.

for those same-sex couples in utah who got married last month, you can file giantl jointly on r federal tax returns but not state tax returns. the conflict is escalating even though both sides insist they are working towards a cease-fire. 184,000 people have been displaced, and forced to flee their homes since december. many have run to u.n. shelters for safety. many have run to neighboring countries. and the u.n. said it has taken it's capitol and will have the oil fields under control. we are there with more. >> they say that it could be a

good thing. it could give them an upper hand in neighboring ethiopia. they're waiting to see what riek machar's next move will be. another part of the government will be facing people and telling them when it will be safe to return. people are waiting to get out. some say they've been there for days, but they don't feel safe. thousands are sleeping in u.n. bases and makeshift camps across the country because they feel the violence is still escalating and they're too scaring to home. in juba people are saying even if the violence actually ends there is no guarantee to thanksgiving it will last long. they've seen this kind of thing before, it's a temporary cease-fire and temporary peace, and then violence erupts all over again. people say that real issues need

to be addressed. and until that is done, if a peace deal isn't decided in ethiopia, it will only an temporary one. >> a spokesman for the south sudan knees rebels spoke to reporters saying government forces have turned to looting in bintu. >> the forces entered bintu town. and the information i'm receiving from the ground is that the government forces are gun looting civilian property, killing women and children. this is what is happening in bintu, and resources are saying that they're burning by the forces. >> those tox are supposedly to a cease-fire agreement. the rebels insist on having 11 political prisoners freed so political negotiations can move forward. uganda has the largest

number of south sudanese fleeing there. hundreds are tired, hungry. we go to their story. >> reporter: these children had to run for their lives. they're already traumatized, and now they lost their parents. there are thousands of refugee who is left fighting in south sudan. after days on the road they reached in holding center. now they're waiting for help. >> she said she had to hide in the bush for three days. she said she stepped over more dead bodies than she could count. >> when we crossed the river some people drowned. i got separated from my son. i don't where he is or if he is alive. >> trucks come to take them to a camp. they're hope to go find food and shelter. they're all taken to the

reception center. >> people brought whatever possessions they could carry when they fled. mostly mattresses and pans but they couldn't bring much because they traveled for hundreds of kilometers. they put up simple shelters using bed sheets and blankets to keep the sun off because it's dry hot here. people are cooking what food they have left but waiting for aid agencies to bring more supplies. the number of people here is just going up every day. >> aid workers struggle to register the arrivals. 20,000 people have come here in recent weeks. it's overrun. >> the numbers are great. the need is huge as you look around. there are so many children coming without parents. so many elderly. we need all the support and assistance we can get. >> at the nearby health center, they need assistance more than most. he was shot by soldiers and

robbed. >> i don't know why they shoot me. they shoot me and then take things. they took my money. >> he's waiting to be taken to the hospital for surgery. and like many here he blamed the leaders for making civilians suffer as they struggle for power. meanwhile, ienn and her children look for a place to sleep. they'll wait for days until it's their turn. and then they'll be given food and plots of land to start farming. it's tough but that's what they want for now. they don't expect peace at home any time soon. malcolm web, al jazeera, uganda. >> a new travel warning for americans headed to russia for the winter olympics. we will have details. and i'm robert ray live in

new orleans in the lower ninth ward where $1.5 billion of funds the state of louisiana is sitting on. we're trying to find out where that's going coming up on al jazeera america.

>> every sunday night, join us for exclusive... revealing... and surprising talks... with the most interesting people of our time... >> as an artist you have the right to fail... that's a big right to have >> his work is known across the globe. but little is known about the gorilla artist behind the glasses... we turned the camera on the photographer shaking up the art world. >> 2... 1... that's scary jr... >> talk to al jazeera with jr only on al jazeera america

s. >> welcome back to al jazeera america. congress and billions of dollars sent to louisiana after hurricanes ravaged the state, but some of that money has not been used. the state received $14.5 billion in block grant funds. all of that money, $1.5 billion still has not been spent. what is going on here? robert ray is in new orleans. robert, what does the state government have to say about the unused money? >> reporter: well, tony, unfortunately the state government is not responding to us today even though we put in multiple requests in the

morning, and we're told we're going to have answers to our questions. we're still waiting. in the meantime we're in the lower ninth ward. you can see a lot of work where families lived. this is why katrina hit the hardest. everywhere you look its sort of a disaster from one side of the treat to the next. let me bring you over here. you look at this house, this old apartment building here. a total shell. so the $1.5 billion community leaders are wondering where it is. a woman over there in this house over there that we talked to said she would like to find out where the money is being spent. she's afraid to ask because she doesn't think anything is going to happen any way. the governor, bobby jindal said in earlier reports said he's happy with the pace of center. other state centers and people here are wondering if congress can take back that money and perhaps redistribute it so that

the fight, the bureaucratic fight doesn't continue here. that may be a problem. let me walk you through here through this gutted shell. this is what you see in the lower ninth ward. pretty much where you look buildings like this, homes, structures like this, full of disaster, and just sitting here block after block, and we talked earlier to folks earlier today also, one of the gentleman who runs the lower ninth ward development group said he's appalled that his neighborhood looks like this nine years later. where are the funds and when will they be spent to make new orleans better, tony. >> robert, in the lower ninth ward, thank you. it was one of the signature programs of president johnson's war on poverty. head start is designed to give children from low-income families a better chance to succeed in school.

lisa stark reports its funding could be at serious risk. >> reporter: by all accounts martina is an accomplished woman, law school graduate, former school board member, former congressional aide. she said it all started in a room much like this one. >> head start made me believe that school was a happy place. school was a place you could go and grow and learn. >> reporter: she grew up in chicago, daughter of an african-american single mom. her father stressed education. that helped, but so did lessons learned in head start. >> when i entered kindergarten i felt confident. confidence is your ability to master anything new. again there are these subtle things that i think head start may not get credit for. >> do you like coming here every

day? >> yes, it's my favorite class. >> why is that? >> this is my school. it's my school. >> the three- three and four yes get more than education. they get two meals a day. >> head start serves 30 million children and in its half century operation even today there is an ongoing debate about its effectiveness. >> two studies funded by the government found that the benefits of head start appear to fade. >> the research done by the federal government shows that there are no lasting benefits. that includes not just economic or educational, but social and emotional. >> reporter: neil mcclue ski believes that head start should be phased out. >> the research does not support at all continuing head start, and certainly not expanding.

>> reporter: the obama administration has tried to boost standards for head start centers. the latest congressional budget deal has been cut back many parents say the program is a life saver. >> my son is learning, and it's so beneficial to me that, oh my gosh, i'm about to cry. it's so beneficial to me because they've helped me so much. >> reporter: martina hone understands completely and has started a local non-profit to help kids like these succeed after preschool. lisa stark, al jazeera, washington. >> marijuana sales in colorado have topped more than $5 million, and it's only week one. legalized sales began januar january 1st. one business owner describes business non-stop. there is some problems because marijuana is banned by federal law businesses can't get bank

accounts and have to handle a large amount of cash. still ahead, a document dump related to the chris christie bridge gate scandal. will any of it point back to the governor? and why the government is warning americans who are plan to go travel to the olympic games next month.

>> welcome back to al jazeera america. here is a look at your top stories. up to 70 million more customers were affected by that massive data breach. that means private information of more than 100 million americans was compromised. the cyberattack may have gathered more information than originalled reported, names, e-mailing addresses, phone numbers. the labor department for december 2013 was a disappointing one. unemployment fell to 7.7%

because many americans have stopped looking for work. health officials are warning people not to bathe, drink or cook tap water. chemical leaked from a fact in west virginia's capitol. 300,000 people across the state are affected. the u.s. government has issued a warning for all americans attending the olympic games in russia next month. they warned that health facilities are untested and there are we're joined by lisa stark. what propertied this alert? >> reporter: it's not unusual for the state department to issue alerts like this for the olympics, they've done it before, but this alert is extensive. they have no indication of

specific threats against americans but they urge americans to remain attentive regarding personal security at all times. there is a lot of unrest. three terrorist bombings against public transportation since mid-october, 30 people have died, and there is a terrorist group in this area that has threatened an attack in the olympics. avoid large crowds and exercise good adjustment. there will be 100,000 security personnel there. they're already start to go parole the areas around the game. there will be security but you have to be really aware of your surroundings. two americans who won't be there, the president and vice president. they indicated they're not going. >> lisa, appreciate it. in washington for us. thank you. hundreds of new documents released just a couple of hours ago relate together political revenge traffic scandal in new jersey, the release comes a day after governor chris

christie apologized for the huge problems those lane closures caused and fired the top aide involved with the scandal. david? >> reporter: i drew the short stick in this. it's actually pretty interesting. these are documents released by the new jersey state assembly transportation committee, and these are documents that are associated with a number of things. e-mails, text, private message. the headline to come out of this it appears based on these documents that chris christie had a meeting with the chairman with the port authority, the agency that oversaw the gw bridge and all the tunnels. he had a meeting with the port authority david samson one week before christie's deputy chief of staff asked port authority asked to call difficulty for mayor of fort lee. is it possible this had something to do with what happened later, and maybe this

is where christie's aids got the idea if they wanted to exact political retribution on fort lee perhaps the fort authority would be an useful agency for them to try to do that. a couple of things. davids wildsteen another port authority official who took the fifth yesterday. all these documents related to his effort to take the fifth. when he appeared at the committee yesterday, that's when the committee put these documents into the record and released them this afternoon. and most of the documents show things like traffic patterns and maps and charts and graphs with traffic and how often the traffic is going through, and they all indicate that this agency, the port authority, and the people who were running the george washington bridge were facing enormous, enormous backlash to these efforts in september to take four lanes of traffic going from fort lee, and condense it into one. one of the e-mails is from robert durando.

here are some of the maps they're showing. most of the main i-95 traffic goes forward. this e-mail is telling. it gets to what the whole tone of this is. in this particular e-mail, i don't know if you can make it bigger. particularly upset that no one either civilian or had the curtsy or neighborhoodly intent to call either the mayor's office or fort lee police department about testing a new traffic pattern. this document again from the general manager from the george washington bridge, everyone is looking a at the mess that this created, there are hundreds of e-mails calling the port authority saying, what are you doing? my commute took three hours today. how could you do this? how could there not be advance public warning. this shows an agency that was

besieged. they're all trying to figure out with the media inquiries, a and what to do with folks who are threatening to go to media, and you have david wildsteen a chris christie appointee who responds to this, we're going to continue this test another day. four days it went. the other part about this, we heard some of this at the news conference, there is another figure involved. patrick foyer, a port authority executive, second beneath the chairman. he said earlier on and testified there was no traffic study. we never ordered a traffic study. he has been a thorn in the side of chris christie and his aides. he sent a memo to the governor's aides to all port authority officials to the george washington bridge manager said this is a hasty and ill advised decision, it is a possible violation of state and federal

law. he's waving the red flag saying why did you do this? this is a possible violation, yet everyone kept it quiet until documents were released this week. >> possible violation of state and federal law. we'll pick up on that point. this scandal may lead, may lead to some serious legal issues, problems, troubles. six new jersey residents filed a class action lawsuit against the governor of new jersey, the port authority, jamie floyd is with us. jamie, good to see you again. is it clear at this point that there was a crime committed at all either on the federal or state level? >> well, nothing is clear at this point. >> nothing is clear. >> but what we do know is that federal investigators are looking into it. state investigators are looking into it, and lawsuits have been filed. people think there is a

possibility of legal liability and perhaps criminal civil criminal liability. on the federal front there seems to be one statute that applies, and that would be something called the federal honest services fraud act. can you believe that? there is such a thing, and it was limited by the u.s. supreme court such that you would have to have bribery or something very concrete for it to apply. i don't think it's going to apply here. but whenever there is a federal investigation, there is always the possibility of obstruction cropping up. so people better tread very carefully as this investigation goes forward or obstruction charges, federal obstruction charges could apply. the state laws are a lot more promising because there is official misconduct, and those laws are very broad in terms of the ethical obligations of these officials not to violate their duties under new jersey law, and that can be pretty broadly applied. >> so chris christie, he said he

knew nothing about it, evidences lied to, that's as blanket a denial you can have i've seen in a long time in political context. there is jeopardy here if anything surfaces. >> the bottom line, and i think you know this, you better be telling the truth. he better be telling the truth. then there is the question of his ultimate responsibility when we get to the top of our conversation here, those civil lawsuits filed by citizens in new jersey. six of them so far, but they're filing as a class. whether he knew or not he could have ultimate responsibility there. they're going to have a tough time establishing themselves as a class, and then there is the question of how much damage they actually sustained as a result of the traffic jam. we all heard about the one woman who did die, the 91-year-old woman. we should clarify she is not part of that class going forward. >> jamie, one more, david wil wildsteen invoking the fifth,

totally his right. >> absolutely. you have that right, and i would advise obstruction is something that these folks have to think about. i advise these people to be consulting with their lawyers. >> jamie, legal contributor for us. thank you. for the first time the u.s. government is naming two armed libyan groups and their leaders as terrorists for their suspected roles in the bengahzi consulate attack. they're accused of carrying out the attacks. both groups were formed after the fall of moammar qaddafi in 2011. neither group has affiliation with al-qaeda. the u.s. also named a group in tunisia a terrorist organization. they attacked their embassy in

tunis three days after the attack in bengahzi. both countries have been in a diplomatic sparing match after an indian envoy was arrested and strip searched late last year. she returned home a few hours ago. >> her arrest caused one of the most serious breakdowns in diplomatic relations between india and united states in years. but her return to india the end of a month-lone stand off is now in site. >> the u.s. government requested to wave the immunity. on 9 january 2014 the government of india declined to do so, and transferred the chancellor to the ministry of external affairs in new delhi. >> at the time of her arrest was india's deputy consul general in new york city was

retrospectively granted diplomatic immunity, but she had been indicted of crimes. before she left she told the press in india that the charge against me are false and baseless. i look forward to prove them wrong. however the nanny stands by her accusations of mistreatment. she said, when i decided to come to the united states my hope was to work for a few years to support my family. and then return to india. i never thought that things would get so bad here that i would have to work so much that i did not have time to sleep or eat or have time to myself. because of this treatment i requested that i return to india, but that request was denied. but in india it's the government's response of the u.s. treatment of the diplomat and not the nanny's case that

has been the focus of attention. many indians have welcomed the removal of the barriers outside of the embassy and the withdraw of diplomatic privileges extended to american consular officials. >> she's representing india in the u.s. and i as an indian think the u.s. government. >> a. >> we should be treated as equals in the united states. we're happy that india stood up for itself. >> domestic political pressures have made a part in the indian government handling of this case. there will be elections soon and politicians want to be seen as strong leaders particularly when it comes to defending india on the world stage. al jazeera, new delhi. >> there was a celebration in

central african republic today. with. >> for a long time they have ignored the private lives of politicians but social media has changed that. he has never married and lives with his long time partner. let's look at what hell's has gone on around the country. >> reporter: tony, thank you very much. officials in the u.s. air force say two officers overseeing nuclear armed missiles in montana, they are now under investigation for illegal drugs.

the disclosure has proven especially embarrassing to the pentagon because it comes on the same day that secretary hagel. spokesman said the two missiles launch officers under investigation have been barred from duty and stripped of their access to classified information. remember that it contractor who built the glitch-ridden healthcare.gov ? well, the obama administration wants to forget the contractors cgi federal, so it decided to end its relationship with the contractor. they have demonstrated they're not effective enough in fixing problems. the administration plans to sign a new $90 million deal with a different contractor. attention all g mail users. you may be getting items in your inbox from people that you don't

>> pakistan's prime minister said it's nation's highest bravery award should go to a teenager when he tackled a suicide-bomber targeting his school. thousands are calling the 17-year-old a true hero. maria, we talked about this a bit yesterday. i'm happy we can follow up on this. this kid was special. >> pretty unbelievable. the #is brave heart. on january 6th this teenager, a ninth grader noticed the suicide-bomber approaching his school in the village in the northwest part of pakistan. you see it right here.

and he noticed the suicide-bomber about to enter his school. first he through rocks at him. then he tackled him. the explosives went off. he and the bomber died. people are calling him a true hero. people on twitter, for example, this is an illustration. timtim o'brien writes: . >> they also set up a facebook page for him. you also have the former pakistan ambassador who tweeted out, she wrote : >> and also a lot of people are comparing him to malalla reportedly announced she'll give the family half a million rupees, about $4,500. she writes.

malal la fought intellectually to save her school. and he fought physically to save his school. and you have this one, saying you don't need an uniform to be brave. you don't need a party to create change. he is a hero. >> boy, what a kid. what a kid. maria, appreciate it, thank you. we suffered through the frigid cold this winter, but last spring another form of extreme weather tornadoes hit the center of the country. moore, oklahoma, became synonymous to destruction. azteas "techknow" tells us, ther work is paying off with innovations from the lab that could literally save lives. >> one of the worst tornadoes on

record that went viral. >> we have large debris in the air. >> i think if you live in tornado alley it needs to be a priority. it needs to have a shelter. >> 300 miles from moore in an university engineers work to make shelters a reality. >> what we have here is an air canon that's called boomer. virtual potato launcher on steroids. >> reporter: it performed test on a variety of buildings. some of them failed. through trial and error innovation came through reinforcement and engineering. >> should we load the canon? >> load the canon.

>> wow. >> 103 mph. >> 10 3 mph. >> it's completely fine. >> this particular wall is what we call double wide brick. you have got one wall of brick here and another wall of brick here and there is a cavity full of concrete and reinforcing steel. >> my goodness. joining us is techno contributor, first of all, good to talk to you. first of all, can we acknowled acknowledge--it's a pleasure. >> yes, it's a pleasure. i want to know your experience in the lab. how dramatic the testing is. we know in a tornado anything can become a projectile, but to see it demonstrated in this way, that is startling stuff. >> yes, it was pretty amazing to see 2 x 4 lumbar being launched

at 100 mph at walls. you don't typically think of these huge objects flying through the air, but they can lift massive objects like this. >> so, it's one thing to design a test, right, in this controlled setting in this controlled lab environment. i'm wondering has there been any field testing of structures, and when might we see some of that based on this kind of design? >> the type of object that does tend to be carried by tornadoes. it's a pretty good estimate of the kinds of things that would hit structures. the thing is with tornadoes it's not necessarily the actually, tornadoes themselves that are dangerous. it's what the tornadoes carry.

the sof stronger the tornado, te more power it has to lift items, and that's what causes the destruction to buildings and puts lives at risk. >> is there a push, i imagine there would be, but if not there will be after folks see your report, is there a push for the technology, the cement and brick into new school construction? retrofitting schools will be difficult to do, but applying this to new school construction seems like an idea that makes a lot of sense. >> absolutely. in the segment we visit mickey davis one of the mothers who tragically lost her son. she's pushing very hard to get these new codes into schools. because it is difficult to retrofit buildings. this involved building new forms of construction based on the advice of texas tech university, and involved much thicker walls,

and slightly different designs compared to conventional ways of building schools. it has to start from scratch, but some schools we visited one in the segment in oklahoma, they did use advice from the university to construct a gym that also doubles up as a community shelter. it seems to be very effective. we see that through the testing. >> well, i want to tease this, we don't want you to answer the question, but you're going to tell us what it's like to stand in front of an ef 3 tornado. it's good to see you. happy that you're still here. >> yes, for a fluid that was really fun. thank you. >> we'll be bam with the nation's weather forecast.
