>> techknow's team of experts show you how the miracles of science... >> this is my selfie, what can you tell me about my future? >> can affect and surprise us. >> sharks like affection. >> "techknow". where technology meets humanity. monday, 6:30 eastern. only on al jazeera america. >> this is aljazeera america. live from new york city, i'm tony harris. more demonstrations in baltimore, and freddie gray was in police custody napal despairs and survivors still being pulled from the rubble after saturday's earthquake. but hundreds of thousands are still pleading for clean food and water and saigon, 40 years later, celebrations, and 60,000 americans who died.

baltimore police say that they have finished their investigation into freddie gray's death. their findings are now in the hands of the city's top prosecutor. details of the report have not been released but police have said that the investigation has uncovered new details about gray's being in a police van earlier this month. john terry joins us, and first john what's the situation like on the streets behind you? >> well, good evening to you tony, from baltimore. every evening at the moment, there's a large march which ends up somewhere in the city. and tonight, it was here at war memorial plaza outside of city hall. site of last saturday's big protest and one that's coming up this saturday as well. but this evening, there has been some very very heavy rain. poured down, and the effect of that was to thin out the crowd. so right now, there are far

fewer people here than marched into this plaza a couple of hours ago. we have been listening in the past few minutes to a police briefing as well. and the police said that the curfew will once again be in operation tonight at 10:00 p.m. and they will keep it going throughout the weekend. now, on the freddie gray story there were three surprises today. two of them from the police, one from the state attorney. here's my report on the day in baltimore. >> at approximately 8:50 this morning, our task force aimed at investigating the tragic death of mr. fred fred, turned over the contents of that investigation to the state attorney's office. >> a surprise statement from the police commissioner, the report of the death of freddie gray handed to the state prosecutor 24 hours earlier than expected. >> we have exhausted every lead at this time. and it does not mean that the investigation is over.

if new evidence is found we'll follow and if new direction is given by the state's attorney, we'll follow it with the investigation. >> the state attorney acknowledged receiving the report. saying in a written statement the result is not new to us, we have scientifically investigated our own investigation into the death of freddie gray. and now she must decide whether or not to bring charges to the six officers involved in fred fred's arrest. no word on when that might happen. >> now is our time for unity what their attorney has asked for to seek justice for mr. gray. >> but handling the report early was not the day. the wagon made a stop that was previously undisclosed and captured on a private camera.

>> the second stop has been revealed to us during the course of our investigation and was previously unknown to us. we discovered this new stop based on our thorough and comprehensive and ongoing review of all ctt cameras and privately owned cameras. >> wanted second stop means that they halted the journey four times in all with freddie gray, one more than reported. it raises questions on why the investigation team only discovered the extra stop through cctv, rather than the six officers. five of whom have given depositions. dwight pettit said there's a systemic problem in the city's force when it comes to the poor treatment of the detainees. >> it's almost like a blue badge of courage to move up in the department. >> he previously believed that the police could do no wrong

and in baltimore, it's well-known f. you run from the police you'll be beaten and if you give too much trouble you'll be given a rough ride. >> in the wagons, there's nothing to head onto, and you're going to be to bed around in the wagon which can cause severe permanent injury. >> baltimore has a long way to go if it's to turn the corner long-term, but in the short term, it has turned the corner because of the curfew being imposed and that's largely because of the state troopers and the national guard. they have promised that they won't suddenly pull out and there will be an old pull out and everybody here will know about it, and i assume that they will pull out when the time is right. tony. >> january terret john, thank you.

and a legal contributish, the state goes to the city's attorney. that's marilyn mosey. >> been there four months, and new to the job and she ran against an incumbent and won 35 years young. she's the youngest state attorney in the country and she said she's ready for this task. an african-american woman she ran on a tough on crime platform, but also said that she would be tough on law enforcement in these cases. >> she has gone on the record with that. >> she has gone on the record. and she's going to look at the facts presented in the report. but also independently investigate the case. so boy she's going to have -- i mean she's sort of like a loretta lynch. there's a parallel. because loretta lynch walks in the door and gets hit with this case african-american women much more experienced loretta

lynch, but both of them being tried in the early days in office. >> so here's what i know, and i know it's probably the case. the cases all over the country but particularly in baltimore it just seems from my recollection, cops don't get in trouble. >> i know where you're going no indictment. we have seen this again and again. it happens all over the country. and it's infamous. infamous in baltimore. and you were bringing up an important point. you have to go to a grand jury. if she feels she has the evidence to prosecute she doesn't decide i'm going forward. but she has to indictment there are some jurisdictions in the country where you can go forward in other ways, and these are not one of those. she has to go to a grand jury, and i know you can get an indictment a police ride around in the van the whole reason that's done, you never lay a hand on the person, and no one

can see what's going on inside of the van. though now there's another allegation, there was another person inside of the van with evidence to offer. but there are a number of cases on record, tony, of police ride around, where one man had his neck broken, and he was able to establish in civil court that he had his neck broken, and he won millions of dollars from the city of boston. >> so the police revealed today that there was an additional stop. >> yes, that was leaked. they didn't reveal back to us. >> yeah, but -- >> it came out in the report. and when they came to the podium, they said -- in other words, it seems that the officers involved -- >> that's where i'm going. >> they were not forthcoming and when asked about that, the police said, we can't discuss that at this time. so we don't know, but it seems that the officers, the six officers who have been suspended did not reveal that. >> that there was an additional

stop. >> an additional stop. >> and didn't explain it. and the question is how many of these stops have they explained at all? partially, completely at all? >> they found out about this because of private surveillance tape and a woman has now said, yes, they came to me and asked me at my store march my tape. and look, they knew they were going to find out about that. the tape was out there and they say well, we have to be transparent. and yes you do when you find out about that. >> lastly, the longer i think about it, the more troubled i am by the use of the word, thugs by the president and the mayor. >> yes. >> you're troubled? >> yes i'm troubled. and if you want to read about it where i keep my blog, i actually blog -- >> we can put it on our site too. >> let's put it on. because i'm troubled specifically about this point and the reason, it's not just

semantics. it creates a divide that doesn't need to be there. and the word, thug, it specifically refers to a -- not just african-american men but a certain class of african-american men. poor african-american men. and when people say, i would call my child a thug if he engaged in this behavior, but we never refer it that word other than african-american men of a certain class. and we need to not do that in this critical juncture in our history. more to come. >> thank you. >> more to come. >> in earthquake stricken napal, there have been more dramatic rescues. a 34-year-old woman was pulled from the remains of a restaurant in kathmandu just hours after a small boy was saved. >> reporter: a day when some

good news is finally overshadowing all of the bad. two incredibly dramatic rescues. pulled from a small hotel in kathmandu hours after a teenage boy was saved. when he first got stuck in the rubble he couldn't see a thing. >> i didn't know if i was alive or dead. >> he had no idea whether he would make it, but wasn't willing to give up. >> i was trapped but i could move around by crawling in the rubble. >> he was stuck there for five days before being pulled out. his rescue in kathmandu was cause for celebration. ononlookers, so used to seeing dead bodies, cheered for him. and now at a camp, volunteers are optimistic of recoveries. >> [ unintelligible ] doing remarkably well.

>> heaven to be alive llama describes how he got through his ordeal. >> i found wet clothes and squeezed water from the clothes and drank the water and then i found butter, which i ate. >> llama's incredible story gave much more optimism to the people among the ruins. racing as they have forever more bad news, this brought a of -needed respite to a city and country in mourning. aljazeera, kathmandu napal. >> in nigeria today, there were reports of more people being rescued from boko haram, and the military released the new pictures of the nearly 300 women and children who they said were saved from a boko haram stronghold this week. >> nigeria's military said these are some of the 293 women

and children rescued. they were held in severe and inhumane conditions, the military says. they're trying to work out the identities of the women and children, where they come from, and how they were kidnapped. many are hoping that some of those rescued are the schoolgirls that were abducted last year. 219 are still missing. the military can't confirm whether some of the release cued are from chibok. >> everywhere, being assaulted and searched. we hope to --. >> but people who have been campaigning for the rescue of the chibok schoolgirls and other women and children held by boko haram, are demanding that the military announce the identities of those who have

been freed. >> how many more people are still missing? we never had a record from the military that says that a number of people. a number of girls and number of women. men or boys were abducted. >> on thursday, the military announced the rescue of another 161 women and children and promised to release their identities too. they said that the ongoing operations against boko haram are going well. and they expect to free more people who have been held captive by boko haram in the zam bissa forest in the next few days. [ unintelligible ]. >> it's not possible to independently verify what the military are saying about these rescues, because the restrictions have been placed on humanitarian organizations

and the media is accessing the areas where these rescues are taking place but many people are hoping that the military's numbers are accurate. aljazeera, nigeria. >> the nation's biggest scientific and professional organization of psychologists may have secretly worked with the bush administration on the cia interrogation programs. according to the new york times, a group of health professionals and human rights activists have learned that the american psychological association bolstered the organization for torture. they deny it. but according to developing the interrogation techniques, jacob ward said that there's little difference between physical and psychological torture. >> once upon a time and still in some places today torture was a matter of inflicting physical pain, but in the modern era a terrible sort of

pseudo science has applied mostly psychological pain. i'm talking about sleep deprivation, and threats to family members. these leave little or no physical trace on the body, which deprives victims and international courts of crucial evidence. but the thing to understand, the researchers who looked at the distinction between physical and psychological torture have found that in the end, the affect on the victim is largely the same. as the u.n. special rep tour puts it, whether it's bold or mind if the victim is held in a constant state of anxiety the point of torture is to regress the victim to the point where they lose all hope of

control, freedom or intimacy and can do nothing else thank comply. here's the added piece of horror the intelligence science board in 2006, this group put together a report on terrorism and coe.. coercion. they argue that threatening to use this bucket to induce the sensation of drowning through this rag or doing it to someone has no proven ability to get truthful information out of somebody. whether torture is justified or effective, let's put that aside for a moment. here's what we do know. u.s. personnel knew how harmful torture could be on its victims, and they did it anyway. and they ignored what science also knows. there is no proven ability for torture to get useful information out of anybody

whatsoever. >> tony, the involvement of psychologists in this kind of program allowed the justice department, under the bush administration, to say not only was this legal but it was ethical because it was under a jurisdiction of the supervision of mental health professionals and how they defended a program that defended it. and that progression program has been sure down at this point. >> oh, so-called torture memos. and jake, this seems ethically questionable at best. is there an equivalent to the hippocraticect for psychologists? >> there is, absolutely, tony. let me read you a little bit of the code of ethical standards that the apa puts out. and it begins, psychologists strive to benefit those with whom 24th work and care to do no harm, and they speak of what it is to be employed by a third party. and at no point should you allow yourect calling

obligations to be thrown out the window by your obligation to say third party. if there's a conflict between ethics and organizational demands of those third parties psychologists must clarify the nature of the conflict, and take reasonable steps to resolve it, and the final line, under no circumstances may this standard be used to justify or defend violating human rights. >> we have to get some accountability on this. hilliary clinton has a challenger for the democratic nomination. senator bernie sanders is running for president, how he could change the race. and plus, goldman sachs multibillion-dollar investment in bit coins. you heard me. ali velshi is here next.

>> then by himself he jumped in front of the reporters at the capitol and proclaimed his call to arms. >> we now have a political situation where billionaires are able to buy elections and candidates and let's not kid ourselves. that's the reality right now. >> on top of scaling back money and politics, sanders vowed to focus on climate change and reducing america's inequality. and the wealthy need to do more. >> not to ship jobs to china

and their responsibilities are not to avoid paying federal taxes. so we need real tax reform that says to the wealthiest, you have to stop not paying your taxes. >> he served for 16 years as vermont's soul congressman before being leaked nine years ago to the senate. a grumpy grandfather type, sanders is a presidential long shot. he doesn't have a national political organization or fundraising network except for a bare bones website. and even president obama has joked about his campaign. >> apparently they want to see a pot smoking socialist in the white house. >> they could force hilliary clinton, the democratic frontrunner to address her concerns. she's at odds with her party's left breaking up wall street

and free trade. and clinton supports it. and sanders is opposed. >> we have to cut emissions rather than give a green light for the exploration and the production of some of the dirtiest oil on this planet. i think frankly, that is brazen. >> but sanders may also be doing hilliary clinton a favor. he could siphon away from progressive support from martin o'malley a maryland governor who is considered a more form nibble challenger. and he wants everybody to keep the media clean. >> it looks like we're hung up on political gossip and all of the so many opera aspects. >> the senator himself declared that he will not run any attack ads. >> i hate this. >> and instead he believes that democratic voters just

need a leader who is serious about taking money out of politics. >> talking about 24 beautiful capital, he said it belongs to the people and not to the billionaires. sanders is kicking off his campaign before heading to iowa and new hampshire. but it's not just about the progressive vision, but sanders said that he's in the race to win. >> appreciate it. thank you. >> thank you. >> so we had word today that wall street big bank, goldman sachs, struck a $50 billion deal to invest in a bit coin start up. now, goldman is the first major bank. ali velshi of "real money" is here, and tell us more about this, please. >> i always hoped that i would never have to talk about bit

coin again so this investment by goldman might be a turning point, or it might take you back to when rupert murdock invented my space. but it doesn't generate bit coins, but it tries to improve consumer payments using bit coins. the banks are very interested in this, because it allows people to pay use being bit coin without going through a centralized operation like visa or paypal. only one takes bitcoin but the idea that you can and a goods and services using bit coincidental is attractive to poem. >> can you break it down, what is bitcoin? >> well, bitcoin is virtual occurrences, and it allows people to buy things with goods and services.

there are bars and public relationses places that allow people to come in. let's say that you don't have a credit card. nyg nine and russia, their credit cards are not accepted in other parts of the world. you want to buy a dell computer and they actually concept bitcoin. you can pay them online, and i don't know what they do with the bit coins when they get them. the idea is there's no central bank they're created online using an algorithm but public interest has waned. it's widely speculated. and today worth 225 bucks and it went as high as $1,200 in 2013 so in your mind, if you ever think that you want to worry about them again one of them is a payment system. and this is an alternative and the other is a speculative investment. and i would say that most people should stay away from this side of things, kind of

interesting around here. >> gotch a. and what else are you talking about on the program? >> power struggle, tony, ignited by climb at change. the risks and the reward of what's being called climate engineering, and how electric utilities in the united states are making it difficult for customers who want to use solar. >> welcome back, and you can watch "real money" weeknights. that's 7:30 pacific. and coming up next in the program, a big break for three former educators involved in the atlanta cheating scandal. and plus, it's known as charm city. also known as the land of living. but some parts of baltimore are not so charming. the reason why some neighborhoods are still struggling.

>> the unrest over freddie gray's death. crime and struggling with these issues hoping that the protesters will take action. and del walters joins us from baltimore, and just how serious are these problems, and what impact do they have on families? well, tony, here's this crisis by the numbers. according to the baltimore sun they have the 5th highest rate of homicide than any state in the united states. 229 murders in 2013 alone and keep in mind, this is a city with just under 600,000 residents, and one in ten of those is addicted to heroin. and 55,000 are in some sort of drug treatment program. and if you think that all of those statistics and all of those facts aren't realed, you haven't met bernette mcfadden. >> i didn't understand. what could happen to my child. i'm a mother. i'm supposed to be there.

i couldn't understand the grief, i couldn't understand my loss. i had to hold my hand and walk down the hall, and see my child laying on the table. laying on the table, gone. and my two youngest kids, my oldest child said, mom bring him back, mom you're the mother you can bring him back, and i said, i cannot, i can't bring my child back. >> this is the sad fact. mcfadden lost two of her sons to drug related violence. the first was shot in the held

execution style. and the second was stabbed and the third died, all of them in an eight-week span in may of 2005. >> and mcfadden is not alone. this is not an isolated story to baltimore, is it? >> it isn't and that's the sad fact. we were talking to people on the streets. and we were talking to another guy who lost two of his sons to drug related violence. both of them shot execution style. and there's a street named after them, but that does little to comfort. we talked to another who said this is not just an isolated problem, but instead an epidemic. >> trisha rose is a professor of africana studies in race and america in brown university. and carl stokes is a city

councilman from baltimore's district 12. and councilman, let me start with you. can you hear me okay? >> okay. i am pushing in a little bit but i can hear you and by the way, hello and how are you tony? >> great to talk to you again it has been forever. it's good to have you on the program, so let me ask you tell everyone who is watching us what areas what particular neighborhoods in the it city do you represent? >> i represent much of east baltimore. and as a matter of fact, i represent the area where the newly built not quite built under construction senior center was burned down the other evening. i represent? hardcore low income neighborhoods, but i also represent what we refer to as charles village which is near john happen kins university. it's mostly white you know the area upper -middle income.

>> so councilman, what happens on monday? why did the city start to burn a little bit? why did we see the rioting? it's the culmination of what in your mind? >> well, i think that quite frankly, after six or seven days of peaceful demonstrations and protests i think that what happened a few people intent on something different than justice for freddie gray, frankly, who decided to do? acts that were just reprehensible to most citizens of baltimore. but however also, there were a few dozen young people, 14, 15, 16 years old coming from high school, who got caught up in all of that, unfortunately and they feeling anger and frustration, disengagement feeling like people weren't listening to them, weren't taking attention to them, felt like this was a way for a

moment to be heard for a moment. as you know, very much the next morning, most of baltimore, at least those around these areas got out 5:00, 6 a.m. in the morning,morning started to clean up the city. and careful out on the stairs and stood for baltimore and said this is not baltimore and this is not who we are. so for the next three days. >> all i can tell you that's what i was saying on the air here, that's not baltimore. and i'm really happy that things have really started to settle down. and i want to bring trisha in on this conversation. essentially the same conversation and at any point i would like for you to talk to one another. trish a. first of all great to have you back on the program. and give me your perspective and i love it. which is why i keep asking you to come back, what happened on monday and it represents the

culmination of in your mind? >> well, i think when you see a community with that level of outrage, that level of anger that level of frustration i think it's important not to demonize those who have gone too far and burned down buildings and property because there has never been a major riot where that didn't happen. and the reason for that is, the violence that happened to them happened invisibly from a national standpoint or a media standpoint. this is not a violent response, and it doesn't make it appropriate per se. >> what's happening to them happens invilsably. >> so what happens, almost every 20th century black protest that got violent, you had a trigger point of police brutality. and this is not new. we can not understand baltimore or any other protest without putting it in historical context.

so this is a trigger for a much broader set to us, in the outside, non-ghetto context structural discrimination, and it happens in every facet of life not just the police. they are the front line, but they're tremendous factors in education, and the criminal justice system beyond the police and help and joblessness, and circumstances that are literally suffocating and depressing and very violent in their expression >> so councilman, you recognize is that in your years of working for the citizens, your constituents of that city, that there has been a problem in relationships between the communities that you represent and want police, and how would you characterize it? >> well, i think that it's two ways. first of all most of the folk in the city of baltimore in the communities that i represent

have good relationships between the police. they have come out to the police council meetings, and the police community meetings, but that's who they feel close to. at the same time, most people, two minds most people in the community feel like they're a core group of corrupt and bad comes. a core group that's more than a handful of corrupt and bad cops and if they say something to these cops about what's going on in their neighborhoods, often one of the hoodlums that they have talked about comes and knocks on their door and he says, i heard that you talked to the police and talk to them again and i'll be back. we had in my community a family of six firebombed and all killed because they would stand up to the drug dealers and the police, working in concert with the drug dealers. fed information to the drug dealers. so we're of two minds and two hearts. most of our community most of

us very much love our police officers. but we also know, without a doubt, that there's a core group of corrupt officers. >> trisha, do you want to jump in? >> i want to ask the question, carl. of course all cops are not bad. but there's a systemic crisis in the u.s. baltimore is not alone. why does this core group of cops get away with doing the types of activities that they do if the police department isn't corrupt as a whole why is there not adequate leverage to make sure that they don't destroy the whole task force? >> leadership doesn't make it so. they allow things to be gotten away with, and there's a thick blue wall. and so yes most of us feel good about most of our officers but we also feel that by allowing the corrupt to

continue that they are as guilty as. so we have this new reality frankly in our community around this issue and we need our officers, and we need good officers. we want our neighborhoods to be patrolled properly, as any other neighborhood. and we don't want to have 200 300 murders in our town and we certainly don't want to open up drug markets, so we need, for the sake of law and were order to have some sort of relationship a partispatory relationship and we want good cops don't take 'um bridge with their corrupt sisters and brothers. >> can i raise a question, carl and trisha? i need your participation on this as well. why -- it's not just baltimore

why don't the schools in the city perform better for african-american kids, specifically african-american boys? >> right i don't know why. >> but there's black leadership throughout that city, as you know carl. you're a leader in that community. and there's black leadership throughout that city. why hasn't it performed better? >> right. >> to help carl out i'm going to help you out, carm. look -- >> what were you saying? >> i'm going to hem you out carl. because tony is going to help you out. >> show support. >> i mean, look, schools are pretty bad. >> all right carl, let trisha in here. >> the schools are bad for a

lot of different reasons. number one we fund the public schools through property taxes. >> and middle class blight in the 80s and 90s. >> white middle class blight. >> the mayor said that it was middle class blight. it was blacks and whites who left the city. >> but if you look at the u.s. again, baltimore is not an exception. >> it was middle class overall but significant long-term blight starting in the 50s you end up with immediate middle class flight, which has to do with property taxes and when they leave, it's more than when black middle class leave for economic reasons and you have various factors of segregation, and you have a tax base that's shrinking and an

isolated poor community, that has all of these other factors that includes job discrimination and economic, and jobs that have left through manufacturing. you have drug issues, and all of these crime issues that are concentrated. in other words, all of the negative affects of what it means to be poor are extra concentrated in these communities, so when you use the bare tax base, which is very low to fund the public school system, it's not enough. >> i've given a lot of time to this, and i'm surprised that i've been able to get it. so let me give you the last word. >> i just want to thank you for where you are in your concentration, and your producer wanted me to mention that it's your birthday. baltimore is strong, as you've seen for the last 12 days or so, we have only had one or two

bad nights of bad stuff. that was a few hundred people. but thousands the tens of thousands of dollarss of baltimorians are not only demonstrating peacefully, but we're going to stay on the street for the next months until we have justice in this town. freddie gray is the latest. and he's not the only, and he's not an exception. this has been going on in this town for too many years and we're going to stay out here until we get justice. >> pleasure, pleasure, always great to see you and we'll make a run when i get down to baltimore, maybe mother's day weekend. and it's great to see you. thank you for your time as always. trisha, great to see you. and happy birthday. in other news now an atlanta judge has changed the sentences for three former educators convicted of conspiring to

cheat on other tests. the case has gone on for two years now and it has been called watch the biggest cheating scandals in american history, affecting thousands of children. and robert was at the courthouse when the judge announced his decision. >> just two short weeks ago the ten former atlanta public schoolteachers and administrators were charged by judge jerry baxter and sentenced to prison time, probation and fines. well on thursday, the judge had a change of mind and did a resentencing. >> ten years -- 2,000 hours of community service, $10,000 fine. >> now usually racketteering charges are used for organized crime and mob related events, and the judge also pointed out that he thought this was a systematic problem, having to do with poverty. >> there's a lot more to this

tragedy. the poverty and the other hopelessness in a lot of these neighborhoods. children that didn't ask to be born in these conditions, but they're born in these conditions and they need all of the help that they can get out of t. >> after the resentencing, we caught up with michael pitts one of the three former administrators resentenced today. >> how are you doing sir? you were resentenced today and were you surprised that there was a resentencing without an appeal? >> i think it's the judge that can make that decision. i've been surprised about everybody. >> and that's why you didn't take a plea deal?

>> michael pitts and his attorney plan on an appeal, along with the other teachers that were sentenced. and that could take up to two years or more. >> in pakistan, ten men have been sedged to life in prison for the attempted murder of a teenage activist. he was shot in 2012 on her way home from school, targeted by the taliban because of her support for girl's education. the now 17-year-old was awarded the nobel peace prize last year. it has been 40 years since the fall of dying on. what viet nam is like now. plus, more evacuations in southern chile. a long dormant volcano is erupting again.

>> vietnam celebrated the 40th anniversary of the fall of saigon today with a huge military parade. sending congratulatory messages to vietnamese leaders for what is known as unification day. and at the site, a group of former u.s. marines honored the last two u.s. servicemen killed in the two decade-long war. millions died, including 60,000 american soldiers, and ali velshi's scott reports from hochimen city. >> this is here, the same location where the u.s. was in 1975. and the scene of those hasty evacuations of u.s. personnel as well as some of the south viet nam he's who supported them. relations between the two countries have been normalized for 20 years and that's been celebrated. and what is referred to as the american war. the vietnamese soldiers are

marching in front of those grounds where we saw the images. speaking with generations here in viet nam who were born after the war, they have a of different perspective. we talked to a 28-year-old who had an uncle who was a u.s. solder in the war. >> even my generation now we don't want to look at that. most of the -- just to scare people. we don't want war again, we don't want fighting. >> the they saw a 6.3 increase in the economy. just 20 years ago, the united
