>> avoiding tragedies. >> i want a shelter in every school. >> techknow - every saturday. go where science meets humanity. >> this is some of the level driving i have done. this is al jazeera america. i'm thomas drayton in new york. let's get you caught up on the top stories this hour. declaration of war - african leaders vow to aggressively fight boko haram, and are welcoming the help from the u.s. and other countries. o fighting fire with fire - what the men and women battling wild fires are learning in california's state-of-the-art lab. a deeper look at what is called a game changer in h.i.v. the drug is not new, but there's a new excitement.

we get you up to speed on net neutrality - what it is, why it's changing and how it could affect your internet service. [ ♪ music ] >>. >> boko haram has changed and its operation as an al-qaeda operation. >> the president of nigeria addresses world leaders at a summit to discuss islamic extremist boko haram. the last-minute summit was held in paris this morning. officials from west african nations, the u.s. and across europe were on hand, wanting to show they were taking boko haram seriously. more from al jazeera's tim friend. >> reporter: a hastily called summit at the request of the nigerian president, grappling with an apparently ipp surmountable problem under the

international spotlight. as leaders gathered in paris to declare war on boko haram, there was news of another attack across the border in cameroon. >> what we have decided today, nation of intelligence, change of information, centralisation of resource allocation, surveillance of borders, military preps, especially in chad. >> reporter: talk of solidarity, but the leaders have a long way to go in combatting boko haram. president francis hollande admitted they were surprisingly efficient a fighting force. almost nothing from the summit about the abducted group of school girls in nigeria that sparked the latest crisis. the leaders have no idea where they are. an change deal is ruled out. a military rescue operation is fraught with danger. the nigerian president defended his failure to visit the region. it would do no good, he said.

>> interest now is to locate the girls, where they are. these girls are not schedule in chibok. why did the president go to chibok. if the president goes to chibok, it doesn't solve a problem. >> reporter: the leaders need better cross-boarder cooperation, crucially lacking between nigeria and cameroon. according to the leaders, it's a bigger problem than that now, encompassing a threat to the whole and west central africa to a group with proven al qaeda links. they head home with a problem unresolved. the paris location for today's summit is no coincidence. france is north of africa. what happens in the area could be critical to the region. french troops are training to battle the soldiers. >> reporter: lush countryside is as far from the sahara as you

can get. these french troops are gearing up for their new mission. black hawk helicopters simulate dropping small teams in remote locations. this is a french artillery regiment. they'll take the mortars as well. also on display, the tiger helicopter, french made and packed with the latest weaponry. just as in mali, french troops will be seeking out an elusive enemy across the desert. according to the french, the threat is growing. >> terrorism in africa is a global threat. we intervened in marley to ensure not just mallee security and our own security. security in mali means security in west africa, france as well.

>> reporter: the new deployment is designed to prevent armed groups rearming, regrouping and restabilizing. it's about containment, not solving a problem and they could be on the ground for years to come. the french have military appearance. this will expand bases in mali, chad, naminger, nabbing eeno if asso and the ivory coast. post governments are said to welcome the move. francis hollande appears to have the backing at home for a long-term commitment. >> we understand, contrary to the americans, that it's not just about the nature of victory, you need to also make sure that the post-conflict phase goes well. you need to stable and is stick around -- stablilize and stick around for a long time.

french casualties have been light. despite the spending cuts, it's something they can afford for now. as with a military operation with a vaguely defined goal, it's easy to send troops in, harder to know when to pull them out. a group monitoring human rights violations worldwide is not happy about the president obama's response to nigeria. a lawyer for the jubilee campaign told me the white house where are recently began to listen to the group's concerns. emanuel spend a month in northern nigeria and briefed congress. >> there are people who are revictimized by boko haram. we found people, for example, a lady, whose husband was killed by boko haram, her home destroyed. she had to move and live with an uncle. they came to her uncle's place and killed him as well, months later. for some people in northern

nigeria. it never ends. it rains and it pours. i have to say that the congress of the u.s. has been way ahead of the executive with regard to this situation in nigeria. so we have certainly had quite a lot of interest from the congress in the last couple of years. it was the executive that was turning deaf ears to all our warnings about boko haram. what has happened this week though is that a lot more officers are paying attention to us. you don't walk into an office any more and mention boko haram, and get blank stares. you actually see people who are nogeable and are -- knowledgeable and passionate about the subject. back in the u.s. firefighters are gaping the upper black gaining the upper hand in fires that began an tuesday. many are returning to their homes. all have been in san diego

country. lisa bernhard has been speaking to families that fled the flames. i imagine it's been quite the ordeal. >> reporter: it is. a lot of frustrated families out here at the roadblocks. while the firefighters spent their day making good progress, police officers and sheriff's deputies here had to patiently explain over and over again to residents that they may not yet return to their homes. there are evacuation orders in place in many places here in san diego country. there was one couple that was permitted to cross behind this line, and we went along with them as they learned of their loss. dan and susan returned to their home of 32 years - devastation and disbelief. >> we had to see it first. >> the kids grew up. >> it was a two-storey house.

three kids, seven grandkids filling it with laughter. >> it's a huge loss but we have our family and each other. that's what really counts. >> dan says seven other homes have been lost n this remote hillside. this was the cocoas fire, one of a dozen that burnt more than 2,000 acres according to cal fire. the couple were permitted to take a look at the loss. few can get past the roadblocks. he stayed in his home until the last minute. >> flames were too close. i wanted to stay but didn't want my wife to worry so we both left. >> reporter: he's frustrated he can't get in for his medication. he's at a road block. others are at a local high school. fires are mostly cop daned. it's -- contained. it's less gruelling, but the recovery is intense. dan is an architect. >> this is the last job i doesn't want to do.

>> reporter: he says he will, he wouldn't consider living anywhere else. and many people have spent the day at this road block chatting with neighbours, and waiting for word that perhaps they could go behind the line. one is eric. your house is behind the line. >> just down that way. >> reporter: you have been evicted since wednesday. what is that like? >> it's bad. i really want to get home. >> reporter: do you know the state of your home, and what is behind this line and at your house? >> yes, i do. the house is fup. the firemen did a good job, we are appreciative of that. i can't under why we can't get home. doesn't seem like anything is burning. the power is on, a neighbour is back there because he never left. >> reporter: he's relaying information to all of you? >> yes, texting and calling and

letting me know everything is okay. >> reporter: as the frustration rises, maub there's a pap -- maybe there's a panic mode and you're sort of over it. >> yes, i guess you can say that. we got out of this, we got intimate things you need to keep. important valuables. now we want to be home and you want your own bed, shower and clothes. >> you have a baby, a dog. >> yes. >> everywhere had to find a pleas to stay. >> we are lucky. we have family in town that we are staying with. >> you said you know the wild fires can come. you are aware of the danger. what have you done to protect your house? >> you keep the brush clear, trees trimmed. it's an unusual year. it's been dry weather. we are not normally this dry. fire season is usually september, october, after a hot summer. this is different. >> reporter: it is different, indeed. thank you so much. eric and the others are waiting

for officers it say that the evacuation order has been lifted. we under it could be soon. no firm idea of exactly when. back to you the difficult part is waiting. thank you. we are talking about the lack of rain and wind. what role is the weather playing? rebecca stevenson is joining us with an update. >> we had the drought conditions, talking about hot and dry conditions through the stretch the last few days. this area of southern california had record-breaking high temperatures. they are cool, and in large part the wound has changed direction. when we have the east wound, the santa ana winds. when they come out of the east, once they get to the other side they sink. when air sinks, it will dry and compressionally warm. it brought a few degrees to the high temperatures. winds to the west are pushing the fire danger further eastward

into arizona and southern mexico. humidity is higher on the coast with the cool air, but dry inland. we are expecting to see temperatures continue to be warm. tripple dim it heat through -- digit heat through las vegas and phoenix. >> they need relief scientists are looking for ways to better prepare for wild fears, studying conditions and working to slow down the rate at which they odour. rob reynolds explains. >> reporter: a wall of flame leaps into the air and sparks twirl and spin. scientists probe the secret of one of humanity's oldest tools and immemorial enemy - fire. this is the u.s. forest services state of the art fire research lad in riverside california. where university of california's scientists and their students are busy gathering fire data.

marco oversees the research. >> we are trying to help firefighters to better plan the burn, or to fight wildfires. for that we have a controlled fire under controlled conditions, and we are looking how firespreads, what are the influences the fire spread, how was, and we are hoping that that information will be of use to firefighters. >> sensors in the fire record millions of data points for analysis. slower wind speeds make smaller fire. in this experiment the flames didn't reach the upper canopy of vegetation. higher wind speed creates ipp fernos. by the time it has finished the laptops researchers use are covered in ash. wild fires are on the increase

across the western u.s., in part because of drier conditions and higher temperatures due to change. this year's fire season started early. widespread drought turns for efforts into tinder boxes. forest service officer dave says the laboratory research augments firefighters' practical experience. >> these experiments allow us to describe what fire does from a fundamental standpoint with equations and understanding the complexity of fire. >> reporter: one thing is certain - fire will always be with us. it's a force that can never be eliminated, but it can be better understood. that could save lives. the centers for disease control says the mers virus appears to have spread from one to another in the u.s. for the first time. officials say an illinois man tested positive for middle east

respiratory syndrome after meeting twice with a man diagnosed in indiana. federal health officials say he did not get sick as a result. they have been testing anyone that came into contact with the indiana patient. he contacted mers whilst working in saudi arabia. president obama intends to nom snat san on -- nominate san antonio mayor for secretary of housing and development. castro is considered a rising star. he would replace shaun donovan, taking over as director of the office of management and budget. the white house has not confirmed the moves. government forces in yemen are in the fourth week of an offensive aimed at wiping out al qaeda - a fight backed by the u.s. the most visible sign comes in the form of drone strikes. yemen received $87 million in security assistance from the state department and $161 million from the mept gone to -- pentagon to train forces.

al jazeera's correspondent takes us to the front luns. >> reporter: this is a town on the front lines. they are shelling al qaeda positions. the army says these are fighters killed in offensive. these are bunkers and tunnels dug by al qaeda to move in the front line. the armed group retreated, leaving behind weapons and explosive devices, ready to be used in suicide bombings. security forces say they have stopped many revenge attacks and intercepted cars packed with explosives in the capital sanaa. >> translation: we have defeated al-qaeda in this area. their fighters fled. we'll make sure the terrorists will never be able to return here. >> reporter: now this is where

the army is concentrating its efforts. the last stronghold in shebwar province. top army commanders putting plans for a mission to recapture the town. >> translation: al qaeda fighters say they are muslims, but they kill our people. islam is innocent of these people. >> reporter: the government is weak in these areas. tribesman have the final say and their support is crucial for the government to win its fight. >> it's been three weeks since the start of the military offensive against al qaeda. the army says it's a matter of days before it restores control. many al qaeda leaders and fighters have already retreated to remote rural areas. libya's government declared a no-fly zone after what they say was the unauthorised use of military aircraft against armed

militias in benghazi. [ gunfire ] >>. >> 43 were killed, more than 100 injurediest are day. the government says the former general was behind the attacks, and his forces were outlawed. more fighting may be ahead. >> coming up next on al jazeera america. it's a drug that helps prevent the spread of h.i.v. some say promoting its use is a bad idea. we'll take a deeper look next. how new rules may change the way you look at the internet. we look at net neutrality and what it means for you.

squoo welcome back. time to take a look at a drug many are calling a game changer in the spread of h.i.v. the centers for disease control and prevention recommended that high risk people take a pill close to 100% effective in preventing infection. courtney kealy is here with the details. >> reporter: the drug is called

true vardar, it's not new, it was approved in 2004 to treat these infected with h.i.v. in 2012 it was approved for preventing the infection. on wednesday the c d.c. recommended the drug to uninfected patients who were at substantial risk of infection. in other words, americans at high risk for contracting the virus. it is a combination of two anti-retro virals. it works by blocking the virus from entering healthy cells and multiplying. if taken every day true vardar is 99% effective. doctors say it's not a magic pill and people should not let their guard down. >> when you have an intervention with a strikingly high degree of evocation, making it available and recommending that people use it under certain circumstances, not as a substitute for condoms, but complimentary with condoms,

i'm in favour of. >> reporter: in the u.s. the rate of infections hovered at 50,000 cases for the last decade. experts believe true varda can decrease the statistic. to further discuss the pros and cons of the c d.c. guidelines, we are joined by the medical director of h.i.v. services at mt sinai hospital. in silver springs we have tom meares general counsel of the aides care council. trev arda has been out there for some time. what is your reaction to the c d.c. guidelines? >> i think the c d.c. is empowered. another important tool in the h.i.v. prevention toolbox, by elevating it to the level of guidelines, which ultimately hopefully lead to it being elevated to the standard of care for people at risk of h.i.v. >> why do you think it took so

long? >> it didn't take to long. it's a testament to how fast the c d.c. worked. we recommended for approval on the f.d.a. a couple of years ago. they put out guidance quickly, about a year and a half after that, creating a guideline evidenced and database. it's quick for them. >> it's been out a couple of years, but now it's more mainstream. >> yes. >> mr myers, i know your organization disapproves of the c d.c. recommendations. >> yes, we do. what we disapprove of and find problematic - speaking as the world's largest aides organization - is a widespread use and prescribing. whup of the things that is -- one of the things that is not addressed well or what the c d.c. saying is there has been a lack of adherence. this pill has been found to be effective only if taken every day. most of the studies show that

evocation in the studies - the vast majority of people did not take it every day. the primary study - 46% of people in the study were given the drug, didn't take it at all. there was no detectible level in the blood. fewer than 25% took it every day. this is a study where people were paid to participate, they were given monthly exams, monthly h.i.v. tests, monthly sessions on risk reduction, free condoms. that is not the real world. the real world - none of those things happen. in the level of conditions, 25% or fewer could take it every day. the problem with that is when you don't have the daily adherence, you don't have the benefits of the pill. one. two, the other concern we have is risk compensation. a germ term where people teel they are safe -- feel they are safe, protected, they take extra

risks. it happens in every day life. it happens in things like that, in the sexual arena. we have a participation with widespread use, where a lot of people will not be adherent to the once a day regiment, people will involve in risky behaviour and it's a participation for doing more harm than good. if there was a better way to deliver the medicine, we'd be in favour of wide-spread use. >> what do you think of those that say this will promote unprotected sex? >> so in the studies there was no demonstration of risk compensation or increased risk-taking behaviour by people followed. in many of the studies that led to the licensing. the party ners prep study did not -- partners prep study did not show an increased risk. the people getting the medicine

should be at high risk. not for everybody, but those that may not have 100% adherence to condom. >> stand by, i want to take a moment to talk about a high risk community, the gay community. al jazeera's correspondent went to florida to speak to the gay community. let's lisp lisp to -- lisp to the rehabilitation. >> reporter: here doctors prescribe trav arda to people with h.i.v. daily. they are giving it to a handful of people to prevent it. >> someone that can't put on a condom, how likely is it that they are going to take a pill every day either. >> this doctor says studies showed getting people to take the pill is checking. that is why he isn't sure the drug will make an impact on the high-risk population. >> i'm afraid that there's an attitude that is developing or has already developed that you can take true varda and do what

you want. that is exactly the opposite message of what it should be. >> we spoke to a few people that take trav arda, but no one would go on camera. one psychotherapist said that's because there's a stigma about encaging in unprotected sex. 46-year-old registered nurse doug steele has been taking trav arda to treat hiv. he said had it been available to him, he would have taken it. he said it's one tool in the tool kit when it comes to fighting aids. >> people believe in sexual freedom. that means in a perfect world you would be able to have sex with whomever you like and not be concerned. >> steele says without education, it can't help the people that need it. >> in life there's no magic

pill. >> reporter: people worry that fewer will use condoms, putting them at a greater risk. >> the reality is a hot of patients use it as an alternative to condoms. we are right - for years we have been in the middle of a sievo louse epidemic among gay men in south florida. >> reporter: despite hopes that it will be a game changer, the level way to halt the transmission of h.i.v. is to effectively treat people who already have the virus. there is a stigma attached. what is the biggest misconception d true varda? >> the biggest misconception is that it's a prescription that should be provided in isolation. i think of true varda as a gateway job to provision fogzed primary care. it's a way to bring people into a confrontation that they wouldn't be in.

i prescribed trev arda and 50% of the people that present asking for it don't get it. they getother interventions and other things that i offer to them. >> what about the cost? >> it is significant. the guide lines are important in changing the game. they are in definitive. they are something that changes policy. it costs money, it's not a free intervention and insurers are paying for it. the question is what about the people at risk who are not unsured or uninsurable. that's what the guidelines are weresing. >> your organization has an incred ble perhaps. could true varda have an influence in nations battling the epidemic? >> i think in the previous pieces with the doctor, the emphasis has to be an treating people with live. these drugs are just as effective in blocking the spread of h.i.v. in people who are infected. it's up to 100%.

there are countries around the world that have a significant majority of h.i.v. population on treatment, and you see infections go down. namibia, ghana, cambodia - they were on a trajectory to eliminate h.i.v. by 2020 because of mass use of h.i.v. treatment for people with h.i.v. that is where the focus ought to be. >> there's talks of an injectable option. >> there are studies now. it has a life that makes the injections once every three months. that could block infection. studies haven't been done, they are getting under way. there could be an impact with adherence taken off the table. >> and the final words. mr myers, how do we get past the stigma and fight the epidemic. >> getting past the stigma - i

think that we recognise that with treatment h.i.v. is a chronic but manageable disease, that people who are successful, they have a healthy or normal life inspection si. they can work, take care of their families and not unwittingly infect others. that's what we need to focus on. you eliminate stigma by showing people that have something potentially stigmatizing is not an issue. >> final word? >> i agree with him entirely. i disagree with the idea of not allowing every tool in the tool kit to be used. i believe that treatment as prevention is key. it's a central most important aspect of prevention of h.i.v. there are some people that are getting h.i.v. there are high-risk groups where this is happening.

from my perspective and that of the c d.c. and who, we need to use the tools to curb the tide of h.i.v. 50,000 new ipp fbzs, i worked -- ib fction. i worked -- o infections. people treated with h.i.v. get complications. if we cap prevent h.i.v., we prevent transmission and complications. it's a no brainer that we should not limit our access. >> the epidemic is far from over. tom myers - appreciate your time gentlemen. still ahead - net neutrality. what does that mean for you, and how could it affect the way you use the internet. and the health concerns for california chrome. if the colt can keep its tripple crown dreams alive.

the internet highway may split into two lanes. you'll see more of this when visiting favourite sites - the buffering, waiting for the vid yo. the debate -- video. the debate centers around net neutrality and whole controls the internet. >> reporter: disorder at an orderly hearing. the emotion of the federal communication commission reflects the high stakes involved. in a 3-2 vote the commission voted in favour of new rules affecting internet connectivity. >> the consideration that we are beginning today is not about whether the internet must be open, but about how and when we will have rules in place to assure an open internet. >> reporter: the proposal could be internet service providers in

the u.s. charging netflix and amazon more money to deliver their product faster to customers. >> the rules they are proposing is the first time where they allow a 2-leap internet. a -- 2-lane internet. fast for some companies and slow for the rest of us. >> instead of putting tolls, ut f.c.c. should follow the european union model and protect net neutrality. >> fansry hands is a personal assistant service. its staff can do what you don't have time for. cancelling a magazine system or tracking town a parcel at the post office. if they want faster kelentivity, that could -- connectivity it could mean great are overheads. >> it could mean our provider pays more, passing the cost to us, making us wonder whether we keep the feature or charge extra and how do we charge it to the

business. >> reporter: telecommunication minister george food said customers will not be worse off. >> what you should talk about is a fast lane for everybody, and a hyperspeed for others. >>. >> reporter: the f.c.c. decision marks the beginning of a 4-month consultation period and gives big companies with deep pockets to lobby against the change. you heard about the two laps of internet traffic. here is what it means for you. think of providers or isps like comcast, time warper, att and verizon as building and maintaining dumbing tall high -- digital highways too and fro your home, and then you have google. netflix, your local piseria. right now google content travels to your home at the same speed as the menu from pizeria. some say big content providers

should pay extra for a fast lane so content from smaller site shares the highway with everyone else. many say content would move slower, if at all. lobbyists for isps argue they are not slowing anyone down, just speeding up the companies that pay more. supporters say the rules would kill the model of a free and open internet for all. joining me now from washington is chance williams, the associate professor or director at free press. good to have you with us. >> the f.c.c. voted to move forward with rules aimed at guaranteeing app open internet. what is at the core of this decision? >> well, what is at the core of this decision is a response to a court case that was decided in jap, that struck -- january, that struck down previous rules in pleas. the f.c.c. had to move forward. the path they have chosen, we

feel, will pd the open internet -- end the open internet and create paid priority, the fast lane, and slow down the content for everywhere else. >> net neutrality advocates worry that new proposals abandion net neutrality. are you worried the new rules will do that. >> yes. the proposal put forward by the chairman does exactly that. the proposal has to allow for room for negotiation and discrimination online. that is the legal foundation that he chose to build the rules upon. it can't be other than what it is. that's why so many are upset about the proposal. people protested outside the f.c.c. on the day that the rules were voted on. people expressed concern about the rules. hundreds of non-profits and investors. in is something that landed with a thud, and created a lot of concern for the internet economy

and internet users everywhere. >> the heat of the emotions in the video. verizon communications, which brought the initial court challenge to the commission's previous open internet rules issued a statement warning subjecting broadband to strict oversight. why are company like verizon worried about the ruling? >> verizon said, when they argued the case in court that they'd look for arrangements allowing for discrimination, and allow for special arrangements with internet content companies. they want to make more money and make more money by double charging for something they shouldn't have to be required to double charge for. they are looking out for their bottom line, they are not concerned about the memory consumer -- the american consumer. a company like vrzon, or comcast or at&t have a large market

power. in some cases you are lucky if you have two. the fact that they'd be against rules is a big cop certain, and the -- concern, and the fact that there's no rules is a concern for all of us, because we have to go through their pipes to access the internet. >> you mention consumers, we should pay attention. the consumer group said it could negatively exact on free speech and price and innovation. >> for cop assumers your internet -- consumers, your internet content providers could be charged more. that puts a lot of content that want to be in that fast lane out of reach, because it will be more expensive because they'll have to pay the overhead. the internet is a big space for innovation without permission. what will the f.c.c. is setting up currently with the rules - with the proposal they put

forward is an internet where everywhere who is a web - who owns a website or provide web content would become a customer of every internet service provider out there, and have to negotiate terms with them on their own terms, to make sure that their content is not blocked or discriminated against. so certainly the internet economy will suffer. that is why, as i mentioned, so many companies and investors expressed concern about what the impact of the rules would have. >> in the final moments, how do other countries handle net neutrality. >> we have just seep major steps tan in brazil and in the e.u., where they passed strong net neutrality rules. this was something done in the faus of a lot of opposition from the telekom companies in those countries. fortunately the politicians there, and the lawmakers listened to the people who spoke up in overwhelming numbers to say they wanted to make sure the

open internet was protected. the rules have not been put in place yet, and certainly there's a lot depending on the execution and implement kags of the rules. we -- implementation of the rules. we hope lawmakers in the united states pay attention. there's interests that want to make sure the open internet no longer exists. we hope they lisp to the people -- listen to the people in support of it, and put rules in place to protect us all. >> chance williams, associate policy director with free press. thank you for your time. new laws aimed at getting kids to eat. why it's leading to a lot of waist and costing money. >> firefighters in southern california are not the only ones getting cooler temperatures. frosted advisories are out for parts of the east coast next.

welcome back. schools across the country are trying to be heathier. a growing number of lunches includes fruits and vegetables and wholegrains. los angeles is leading the effort but they seem to be losing. >> reporter: from trays to trash. >> usually it's grosses. >> reporter: at hundreds of schools this is what throwing away up to $80,000 a day of food looks like. >> i feel a lot of kids throw away the healthy foods. >> calculated over one school year, that's $14.4 million.

>> this is not okay. >> reporter: director of food services for l.a. unified school distribute can do little to stop it. that's because new federal requirements for the national school lump programme require students to take three food items, including a fruit or vegetable. otherwise districts will not be reembursed for meals. students are forced to take food even if they don't want it, won't eat it and will throw it away. >> we believe in health and nutrition. at the same time, what we don't believe in is that we should have health and nutrition going into the trash can. >> the other reason it's going into the trash can - federal law prohibits children to take upeaten food off campus. in an effort to minimise waste schools set up share tables where unwanted food can be left. the idea is other students can pick up the school and eat it

throughout the day. with the share table a lot of food is ending up in the trash much. david says this is happening at schools across the country. >> what we are trying to do is raise the awareness, education that this is not a district issue, but is a national issue. >> the reality is waste is created because the students are not liking what is served to them. >> reporter: marler is a representative with the school nutrition association, a group representing 55,000 school food providers. >> i think the requirement to having students take three items - i'm okay with that. i think we would like more flexibility. a plum, which is a very popular item with children - we can't serve it because it is not half a cup and in order to meet half a cup we can't afford two plums. >> reporter: the u.s. department of agriculture declined our request for an interview. it cited a harvard school of

public health study that looked at four boston area schools over four days and found:. >> reporter:. >> reporter: david says that is not what he's seep, and before the new regulations he issued a 31-page report calling on the usda to do away with the three item requirement. >> we'd like to see an allowance at a federal memo, or something quickly to happen, to allow the children to take the food away from the meal programme for afterschool or something that they can take and put in the backpack to take home. school districts have a lot on their plate when it comes to serving lump. >> stipes it gives mo --

sometimes it gives me a tummy ache. there's a problem with air back on some tucsan utility vehicles. 137,000 in the u.s. and porto rico are effected. if built between 2011 and earlier this year. humedy says there's -- hyundai says there has been no report of accident. tomorrow we debut an 8-part series examining the legal system, called "the system", and the host tells us why he feels it's an important series. >> we spent a year looking into the criminal justice system, because we have problems in our prison system there are extreme racial inequities, too many wrongful convictions, there are problems with how evidence is gathered. problems with policing strategies we have a great justice system, but sometimes it

runs off the reals, and that is what -- rails, and that is what this series is about - shining a light on injustice. it focuses on systematic problems landing people in prison. sometimes people are guilty, but the sentence doesn't match the crime. sometimes people are put in prison for things they are shouldn't be imprisoned for, due to things like the phenomenon of false cop figses. it's counterintuitive to think someone would falsely confess to a crime. one in three african-americans can expect to go to prip. that doesn't mean one in three african-americans are bad people, but there are policing strategies and social economic strategies that trap people of colour and lower on the socioeconomic scale. the prison population incarceration rate has gone through the roof - over 700%.
