recognition technology. then he was buried, his body released from an aircraft carrier in the arabian sea. bruce leshan is tracking the latest details and developments. the white house does say it is 99.9% sure that that body they dumped in the ocean was of that osama bin laden. >> that may have just been an inartful phrase by homeland security adviser john brenen. the white house is trying to release photographic proof of his demise. he says the administration is going to make sure that at the end of the day no one has any doubt that this was quote the head of the snake. >> u.s.a., u.s.a. >> a night to remember. >> this is for my boy, sumner cowen buried at arlington. >> reporter: the roar of the crowd at the white house for the heroes of shanksville, pa, at ground zero, a celebration of the death of osama bin

laden. >> carried this to iraq and afghanistan with me. >> reporter: he lost his firefighter dad in the twin towers. >> this means that it's a victory for american patriotism. >> reporter: the president's first reaction, we got it. >> our country has kept its commitment to see that justice is done, the world is safer. >> reporter: american intelligence operatives tracked a courier to find bin laden not in pakistan's remote tribal regions but in a luxurious compound north of islamabad where he had been living apparently for years. a neighbor shot video of the fires after elite navy seals assaulted the mansion, the u.s. had been watching the fortress for months. >> i think it's inconceivable that bin laden did not have a support system in the country that allowed him to remain there for an extended period of time. >> reporter: neighbors included a pakistani military academy and an army brigade headquarters, but residents

insist they had no idea. >> we never thought that osama bin laden would be here. >> reporter: but congress is now questioning military aide to pakistan. >> the pakistani army and intelligence have a lot of questions to answer. >> to feel glad about somebody's death is a weird feeling but when it comes to him, that's all right. >> reporter: the white house homeland security adviser says bin laden used one of his own wives as a human shield. she was killed as were the gatekeeper couriers who owned the compound and one of bin laden's sons halid. they buried bin laden at sea in full compliance with islamic practice. >> i'm sure everybody at the white house is gratified this has happened but they are not saying this is the end of al- qaeda. the threat is over, right? >> they are saying this is not a fatal blow but a very important blow. the number 2 is apparently less charismatic and in hiding as

well and the arab spring blossoming across the region but al-qaeda now has many, many tentacles and some at a still be capable of stinging us again. >> indeed, thank you very much, bruce leshan. we are here at the pentagon memorial to 9/11 and you might want to know and keep in mind that the atmosphere here is quite a bit different from what you saw at the white house and other places last night. in fact, a few minutes ago some of the folks you can see milling about over my shoulder here were singing god bless america but in a quiet respectful way because after all, this is a place of reflection and of mourning. as you know, there are 184 benches here all dedicated to each life lost here, almost 10 years ago. that quality not lost on those who took the time to come by. everybody we talked to said this day is a very special one. >> we wanted to come with the other folks who are here at this public memorial, you know, and solidarity with the events

over the last 24 hours, to be honest with you, and in connection with the events of 9 1/2 years ago. >> were you reacting to the bin laden news? >> yeah. it was powerful. i think all across the country we have taken this moment to think about the last 10 years and what it's meant for our country. >> reporter: obviously it has an incredible emotional impact, even on the folks we talked to, none of whom had actually lost anybody personal in their life at 9/11 but for the loved ones of the 9/11 victims, the death of bin laden is very personal, more personal. sarah m. clark was a washington school teacher who died here at the pentagon on flight 77. scott broom joins me now with reflections as with the man who planned to marry him. >> his name is john milton wesley. and you would think today his first reactions would be like

veg sequence was -- vengeance was hit. instead he shared a sense of retaliatory attacks and shared a sense of anxiety with me today. >> this is no holiday. >> reporter: john milton wesley, fearful that the death of bin laden may unleash revenge attacks all over the world. >> i'm very anxious. i think it's important that we look at this, see there's an accomplishment for security, american security. but at the same time we have to look forward and remain vigilant, it's not over. >> reporter: on september 11th, 2001, wesley was planning to marry sarah m. clark, a washington school teacher. the couple had shopped for wedding rings just two days before she died on american flight 77 here at the pentagon. this is the bench dedicated to her at the pentagon memorial. she was chaperoning students on a trip to california. wesley got the news about bin laden just before midnight. history started replaying in his head. >> i thought about sheikh

khalid mohammad, i thought about all of it, you know, i mean, i think for those of us who are close to it, it's a strange feeling, you know, you get osama bin laden but, you know, at the same time you think about the fact that there are a lot of people with the same mental at that time who are -- mentality who are still out there. >> reporter: the surprise for wesley not that osama bin laden was hiding in nearly plain sight but appears there was very little security around him when the attack came. memories of clark, he said, included a chance conversation they had in the weeks before she died. her concerns about the suppression of women's rights by islamic fundamentalists. >> and i remember saying to her that there were some people who were not prepared to continue to live in a society. i want to minimize the chance for people to go through this

again. >> reporter: wesley does communications for maryland's transportation authority. he has authored two books on islamic american relations, very much involved in the future installation of a 9/11 memorial in baltimore. for him that event has tinted his entire life every day since then but also for him the death of osama bin laden doesn't end anything. he says for him it's just another step forward. >> no closure but a step forward. >> that's right. >> thank you for that. we appreciate that. now the death of osama bin laden now bring the fbi's list of most wanted terrorists down to nine. bin laden's picture on the fbi website now has the word deceased over advertise photo -- his photo. still bin laden's deputy is still out there, on the list, the u.s. offering a $25 million reward for his capture. lesli and anita. >> thank you. as you've been mentioning, homeland security officials say the death of osama bin laden could inspire some retaliatory attacks against the u.s. >> and d.c.'s metro system is

beefing up its police presence until further notice. matt joins us live where riders are being urged to report anything they see, any unattended package, suspicious behavior. >> reporter: even though osama bin laden has now been killed or perhaps especially since he's now been killed, this is no time for americans to let their guard down. there's no question that the death of osama bin laden has for the most part made for a happier washington today. >> generally death is not a good thing but this time it is a good thing. >> a lot of people feel that justice was served. >> reporter: but the question is, has it made for a safer washington as well? >> i think it has some effect. >> reporter: chief michael at taborn head of the metro transit police, he said bin laden's death has increased the possibility that terrorist groups will try to attack a major u.s. symbol like a transit system. >> there are people out that have an intention -- have intentions of doing some warm. >> reporter: as a result he increased security throughout

washington's bus and transit system. >> as a result of this increased security, our customers are likely to see an increase in uniformed police officers in the system. >> the chief was quick to add that the increase in security is a precautionary measure and not a response to any specific threat. >> i think that is very much a wise thing to do. >> reporter: charlie allen says precautionary measures are probably a good idea right now. the former chief intelligence officer for the department of homeland security, allen says it's possible that terrorist groups could be planning to avenge bin laden's death with a dramatic strike at a key u.s. target. >> i think there will be efforts to try to conduct acts of revenge for what has happened, mass transit is and has been a target of al-qaeda. >> reporter: so increased security for the foreseeable future on washington's subways and buses but what about the national threat level? we will tell you about that coming up tonight at 6:00.

>> matt, thank you. let's take it back out to you at the pentagon, derek mcginty. >> reporter: lara logan joins us live and thank you for being here. thanks for chatting with us. what details are you hearing now perhaps about the raid that killed osama bin laden? >> reporter: well, you know, a number of details have come out in terms of the compound itself, that it was eight times larger than any of the surrounding buildings, that it certainly caught the eye of the u.s. analysts who were looking at this from the very beginning, not just for, you know, the signs like the 12 to 18-foot walls, both on the outside and inside the compound, but also for the kind of activity, the normal signs of activity that you look for that weren't present, for example they had no trash collection, they had burnt their trash and there was no phone system, no communication system fit 2nd down into -- fitted into this house which was valued at at least $1 million which in pakistan is even more in real terms.

so and what we know is that special operations team of navy seals did the infiltration, they are the ones that went room to room fighting and they are the ones that found osama bin laden. he was killed pretty quickly and there are talks of resistance but nothing significant enough to have wounded any of the american operatives that were involved in this. and, you know, that they -- interestingly, what one former delta force commander said to me is that they would not have pulled that trigger until they knew they could have proof because they knew how critical that would be in this particular situation and that gives you a sense of just how up close and personal this operation really became and in the end osama bin laden was looking his american killers and executioners if you like in the face. >> you mentioned proof. a lot of people would love to see a picture or video of this. any idea why it's taking so long for us to get ahold of that? >> reporter: what we understand and of course we don't have a way to verify this but the reports coming out from u.s. officials is that the photographic evidence is just

too graphic. there are consequences to all of this and counter terrorism officials have told me that, you know, what they don't want is to inflame the situation. they are mindful of the fact that that could spark lone wolf attacks, you know, some individual who is out there who is impossible to track because they don't have a record and impossible to stop from going out into a public place and taking revenge against unarmed civilians and so that may be one of the reasons. you know, it seems if you even look at the way president obama is handling this, there's no signs of jubilation and glee. he's playing this very, very straight, trying to look in command and in control but not trying to throw fuel on the fire, if you like, and so, you know, the consequences of releasing something like that are definitely foremost on official minds. >> i understand. lara logan, thank you for your time. i appreciate it. lesli toss it back to you. >> president obama has made it clear u.s. is not at war with is islam still guarded

responses to osama bin laden's killing in some smarts of the muslim community. here in our area bruce johnson has been covering this story. what are you hearing? >> reporter: a lot of muslim americans in this community and others throughout the country feel as though they were unfairly targeted after 9/11 and they are not sure that the killing of osama bin laden will change any of that. prayers were going out as the national islamic center in washington -- at the national islamic center in washington. but afterwards not even the imam was willing to talk about the slaying of osama bin laden. can you talk to me about osama bin laden? what's the reaction? we did get a few guarded comments from a man who didn't even want to give his name. >> if he did it, i'm against him. >> reporter: why did you say if he did it? is there some doubt that osama bin laden is responsible -- >> we see a lot of movies, you know, but still, you know, al- qaeda, i'm --

>> reporter: far away at union station, cabs lined up looking for passengers. and osama bin laden is dead. what do you think? >> good for the world. >> reporter: muslims here there was relief, maybe even gratitude that bin laden had been killed. >> good for the whole world. >> reporter: should we be on alert, concerned by retaliation? >> yeah, that's going to happen. >> reporter: those warnings were echoed by tourists to washington. >> 10 years, i'm a little concerned there might be retaliation. >> reporter: that's wes back there, the cab dispatcher here at union station. he told me today he didn't need a directive from the mayor or the president to be on alert. he says the killing of osama bin laden will only encourage other terrorists. call it fate, this tourist was in new york on 9/11 heading up that city's emergency medical system. >> several of my people died, so it brings a closure. >> reporter: that he should be in d.c. when bin laden was killed. >> i just hope this was the end of an era and i hope that we

can give back -- get back on course where we were back before it all happened. >> reporter: this is going to make your trip to washington a little bit better? >> we will remember this trip forever because of that. >> reporter: a lot of people were saying that today. a lot of muslim leaders told us last night and today, this is not the time to be silent. make this a teaching moment. this is the time to speak out against terrorism against bin laden and everything that he stood for. lesli. >> still you have to understand that some muslim americans may be concerned that they may be targeted as many of them were after the 9/11 attacks. >> reporter: absolutely. let's face it. there is bias out there and a lot of is based on ignorance. one of the muslim leaders said last night visit them and they will visit us. i mean, you know, knowledge is the best way to combat this ignorance at this point. for the most part we found there wasn't rejoicing in the muslim american community but there was gratitude, there was a lot of relief that bin laden is now dead. >> thank you. anita. >> thank you. from relief to revenge, the

death of osama bin laden bringing mixed reactions around the world. we are going to bring you the latest from overseas. around the country including here at ground zero, americans are reacting to the news of osama bin laden's death. i'm scott goldberg in lower manhattan. the story is coming up.

u.s.a., u.s.a. >> as word leaked out of osama bin laden's death, new york city's ground zero had the feeling of a sports stadium, long viewed as hallowed ground for many, it was filled with clintons and cheers into the wee hours -- with chants and cheers into the wee hours of the morning. in new york's times square, hundreds were there to take part in this celebration. for the families of the 9/11 victims it is a celebration that is bittersweet. scott goldberg joined us -- joins us live from ground zero where a steady stream of people have been gathering there today to reflect. >> reporter: it is a much more somber atmosphere at ground zero today after those parties last night. today people who are relatives and friends of the victims of 9/11 came back here and while they too say that they are happy to know osama bin laden is dead, for them it is mixed with a sadness that will never fully go away. tara joins thousands of people

visiting ground zero as news of osama bin laden's death raced around the globe. >> it's a victory for the rest of the world, but for us it's personal. >> reporter: her brother john died in the twin towers just on the other side of this gate, a devastating loss made worse as the hunt for bin laden dragged on for nearly 10 years. >> to have someone who promotes hate and evil, i'm glad he's dead and i'm glad that he was killed and i'm glad that he was shot in the head. >> reporter: this person also lost a brother, an accountant who worked in the twin towers. for her the day is bittersweet. >> it's not like i'm happy that somebody died. you understand? but it was my brother's killer. >> reporter: all across the country americans welcomed the news of bin laden's death but here at ground zero where nearly 3000 people died, feelings run especially deep. >> it's great to be an american man, it's great to know that this monster is dead, you know.

it's been a long time coming. >> reporter: still along with the celebrating comes new anxiety. >> i first -- my first thought was should we leave the city. >> reporter: why? >> because of retaliation. >> reporter: you're expecting that? >> could happen. >> reporter: in fact, security officials are warning about possible retaliatory attacks, while americans understand that danger, for the moment -- >> u.s.a., u.s.a. >> reporter: they are safe soaring a -- savoring a long, hard fought victory. at ground zero today the crowds have been slow but steady. new yorkers and tourists from all over the world observing this day that so many people thought would never come. anita. >> scott goldberg, thank you for that. we appreciate it. the death of bin laden is dominating newspapers nationwide from california to connecticut, the museum displayed the headlines with word of bin laden's demise. the miami herald headline simply declared he's dead. we caught up with some people outside of the museum this morning. >> it's been a long time coming

and it's really something to celebrate. >> i think this is something americans have wanted for quite a while and i served in iraq last year so for me it definitely hits home a little bit and i'm really happy. >> the museum displays front pages from newspapers around the country outside its location on pennsylvania avenue. museum officials said their website crashed this morning because of the high demand for the news of bin laden's death. we have also got some breaking news. traffic news to talk about on interstate 66, our monica santani has all the details. >> we are looking at video of the accident where virginia state police have been on the scene of a fatal crash in fairfax since 3:45 this afternoon. the crash involved two cars that occurred on the westbound lanes of 66 between route 50 and route 7100. there's no information on the deceased but i can tell you that there were no other injuries and the accident reconstruction team is on the scene. they are investigating the cause of this accident,

westbound on i-66. in fact i'm going take you over to a map and show you what you can do. right now virginia state police not letting you go any further on westbound 66 than right here at route 50. now what you're going to do is take that over to route 7100 and back over to 66, but if you're familiar with 60 -- this area and 66, you can go ahead and take west sox road or monument drive over to the fair lake parkway. the lanes will probably be blocked until at least 5:30. >> thank you for that. and there are other record breaking news in the tornado world here. >> there really is. now, these are preliminary stats and we are going to show you the tornados while i talk about these stats but last week right now a record setting 312 tornados. >> in 24 hours? >> no. last week. last week. >> okay. >> in one day -- >> this is nationwide? >> yes. in one day, 226 tornados, okay? >> wow. >> that's the record. that may be shaved down a

little bit in that it's only -- right now ahead of the april 3rd, 4th outbreak in '74, we had tornados, the tragedy in '74. and in terms of death it's right up there in the top five with 334 dead in 24 hours last week nationwide. so a really incredible record setting event and we will get the numbers and we will refine them as we get them, we will pass them onto you. as far as we are concerned, we are actually in pretty good shape. we have clouds coming in. we are going stay dry. the nats are actually in town hosting the giants. very nice night for baseball. temps in the 70s and maybe falling into the 60s before the game is over, that's really pretty nice. we have clouds around, at this point thunderstorms back in ohio, and also indiana and kentucky and we run the risk of some thunderstorms but not until late tomorrow and tomorrow night. look at the temps, what a difference a day makes, only 61 yesterday for a high, 75 right now in gatingersburg in -- gaithersburg and downtown, 79

in leesburg and mid-70s in martinsburg and haggars -- hagerstown. milder tonight, even warmer tomorrow, thunderstorms late on tuesday and especially tuesday night, and then much, much cooler on wednesday. we may lose 20 degrees between tuesday and wednesday in terms of high temperatures. here's our futurecast. we will put this into motion, by tomorrow morning, just clouds but it will be plenty of breaks in the clouds south and west of town through manassas and fredericksburg. bring your shades. by afternoon plenty of brakes -- breaks although seeing thunderstorms develop back to the west. tomorrow partly cloudy day with temperatures in the low 80s. then we do see a line trying to form west of town. if you get home early tomorrow by 6:00 or so, you'll be ahead of the storm so to speak but then the storms and showers roll through and again the best chance for anything heavy for us will be between about 6:00 p.m. and about midnight. after that it goes to plain old- fashioned rain and kind of a cold rain too.

expect a wet, cold morning commute on wednesday with temperatures in the 50s with plenty of rain across the entire metro area. so for tonight then, we are looking at partly cloudy skies, breezy and mild, 56 to about 64, winds southwesterly at about 10 to 15. really almost like summer tonight, 63 in arlington, 63 downtown and a few upper 50s in rockville, bughee -- bowie and out towards fairfax. tomorrow breezy, mild, 50s and 60s to start but it warms up quickly, partly cloudy, even warmer, thunderstorms are possible late, high temperatures in the lower 80s. next seven days. >> on wednesday morning rain and showers, nothing severe wednesday morning but wet, only 62 and then kind of cool on thursday and friday, some clouds on thursday, 65, maybe a sprinkle on friday, 68, not a huge deal, maybe a sprinkle late saturday and early on sunday and of course sunday is mother's day, back in the 70s and then upper 70s with sunshine next monday. >> okay. thanks, topper. coming up next, what's left

never in my lifetime did i think i could walk 60 miles in 3 days. 60 miles in 3 days-- i can do that. 60 miles compared to what a cancer patient goes through is a walk in the park. from the moment i registered, people started immediately supporting me. we had an outpouring of-- of support. i wanted to do something bigger than myself. the 60 miles-- it makes a statement. i know i'm stronger than i was before, both mentally and physically. i walk with my sister. our relationship has gone to a whole new level because of training together. you meet the most wonderful, inspiring people. i knew that there was something really special about this event. when you accomplish those 60 miles, it's truly life-changing. it was three days of hope.

(man) register today for the... because everyone deserves a lifetime. we are learning tonight u.s. forces who killed osama bin laden would have taken him alive if they had the opportunity. here is the latest. u.s. military officials say they thought bin laden would resist but that there was a quote remote chance he could be captured alive but a u.s. official says bin laden went down firing at the navy seals who stormed his compound. and he was hit by a barrage of carefully aimed return fire near the end of the 40 minute raid. >> the fields retrieved his body which was buried in the arabian sea and the white house says it has made no decision on whether to release the proof photographically that osama bin laden is dead.

derek mcginty continues our live team coverage from the pentagon. derek. >> reporter: well, lesli, you have seen the scenes, i've seen the scenes, people celebrating, overjoyed at the news that osama bin laden is killed. but a day of mixed emotions for a lot of folks, especially the families of the men and women who have given the ultimate sacrifice while fighting our war on terror. kristin fisher joins us live now from the arlington national cemetery where she has been chatting with the families who have loved ones buried there. >> reporter: you're exactly right. i've spoken with several people who had loved ones buried right here at arlington national cemetery and they say they came here today because they wanted to share the news fist hand with that -- firsthand with that loved one. they wanted to go to the grave and tell them that osama bin laden had finally been killed and i've spoken with other people that say they chose to share the moment in a different way. take a look. >> it was just one of those places in history, i knew it just had to be and had to be there with my son.

>> reporter: when thomas cowen saw the crowds building outside the white house, he said he knew he had to be there. >> i've got to be there and i've got to take sumner with me. we have got to share this moment. this is for my boy, sumner cowen, he's buried at arlington. we were more than father and son. we were buddies. >> reporter: both father and son were security force officers in the u.s. air force. sumner was just 19 on 9/11. >> he was anxious to get into the fight. >> reporter: sumner did get into the fight in iraq but injured multiple times and later medically discharged. >> what ended up being his end was the feeling of being thrown away by the air force. in the end, he decided to go ahead and end his pain and he put a bullet through his heart and mine. >> reporter: a year and a half later, thomas is still reeling from the loss of his son, but he says news of bin laden's death has helped. >> it helps, yes, and it brings

a bit of a closure, of course. but it's not permanent. we all know that this is going to continue on. >> reporter: at least he knows today that his son would be proud, proud of his fellow men and women in uniform for a job well done. >> this is what we have been looking for, this is what i fought for, this is what i stood there and then my son took up the fight too after me. i'm always proud of my son. he is, like i said, my buddy, and he was my hero and he always will be. >> reporter: now, i also spoke with one woman here today who said that she feels that her son can now rest in peace finally because the man that he was in afghanistan trying to find and kill is now dead so certainly a lot of emotion here for the families that came here today and a lot of families that i spoke with said they are going to be continuing coming here throughout the week as the news that osama bin laden is now dead continues to spread. back to you, derek.

>> kristin. poignant, powerful, a father's pain. we appreciate that. thank you. the burial of a local marine sergeant killed in afghanistan comes just one day after the killing of osama bin laden. marine sergeant shawn callahan was 23 years old, lived in brentsville, virginia and buried this morning at arlington national cemetery. callahan was killed on saturday during combat operations in helmand province in afghanistan. he was buried this afternoon. back to you. >> thank you: so just what went into yesterday's operation that resulted in the death of osama bin laden? joining us now is retired air force colonel randy larson. he is the former chairman of military strategy and operations at the national war college and he's a senior fellow at the homeland security policy institute at georgia washington university. colonel larson, thank you so much for coming in here today. >> good to be here. >> as someone who flew hundreds of combat missions, we are talking 400 or so and as a former intelligence officer, how do you rate this operation? >> well, i think most american

public do not understand how incredibly successful this was. they watch movies and it's easy for bruce willis and all those folks to do it. this was real. there are so many things that can go wrong and everything i have seen so far, the planning, the execution was perfectly done, even when they had a helicopter have a mechanical problem, they took extra ones this time. not like the iranian rescue mission. >> let's talk about this mission because there's question about whether the primary mission was to kill or capture bin laden. john brenen seemed to suggest there was the possibility that they were -- they were considering capturing him. what's your take away from that? was this a kill mission name name. >> the president last night said and i heard it and couldn't wait to read the transcript and it says after a fire fight, comma. >> right, right. >> they killed osama bin laden. sounded like the fire fight was pretty much over. i think that's what the american people wanted, i think that's the right solution. there is a very extreme remote possibility if he would have threw his hands up, they would

have captured him. that would have been a mess. this is the best solution for america. >> in terms of limiting the casualties that could have been hurt. as we are getting the information, bin laden apparently used one of his wives as a cover? >> yes. part -- this was the way to do this because some of these remotely piloted vehicles they kill a lot of innocence around there and this was very clean, we got who we wanted and this is the -- you notice i have a big smile. >> yes. >> the first time i sat in this chair was 9/12 and i have a lot different facial express today -- expression today. this is good for america. >> you spent a lot of time back with us then, that's for sure. are we safer because of osama bin laden or do we know the answer to that? >> i don't think we know the answer to that. i don't expect anything immediately but i think there will be attacks at some point, whether osama bin laden was dead or not but they will claim this is a retaliation for that. we need to keep our alert and keep going. it's not just about al-qaeda. technology has made it so that small groups of people can threaten large nations now.

yemen. others denounced his death saying it will only strengthen those who support him. this man says al-qaeda and its followers will now take revenge against the united states, but america's allies lined up in support of the u.s. mission. >> i would like to congratulate the u.s. forces who carried out this brave action. >> i welcome the death of osama bin laden, i welcome this news. >> reporter: israel's prime minister benjamin netanyahu called it an historic day. the vatican says it hopes bin laden's death will promote peace and not hate adding bin laden will have to answer to god for killing so many people. now that bin laden is gone, some muslim groups are pushing for u.s. soldiers to withdraw from the region. >> there is no need to stay in afghanistan and there is no need to stay in iraq. >> reporter: but u.s. troops say their job isn't done. >> just because osama bin laden is dead now doesn't mean the taliban will stop fighting us. >> reporter: european

governments with close ties to america are tightening security. >> osama bin laden will no longer be able to bring terror and murder and mayhem to the world and that does not mean that the terror threat from al- qaeda is at an end. >> not -- >> reporter: u.s. officials say al-qaeda will almost certainly try to avenge bin laden's death. carlie d'agata, cbs news, rome. >> world financial markets actually got a boost from bin laden's death. the dollar rose, oil prices went down on thoughts that there will be a prediction of more global security following this. lesli, back to you. >> thank you. in the minutes following the announcement of bin laden's death, a flood of people went to the white house giving us a memorable scene of celebration. they carried american flags to lafayette square rallying outside the north lawn and stayed there for hours. our brett haber -- >> u.s.a., u.s.a., u.s.a. >> today we are reminded that

as a nation, there's nothing we can't do when we put our shoulders to the wheel, when we work together, when we remember the sense of unity that defines us as americans. >> u.s.a. >> historic day in the history of america. >> it would be a dishonor to this country if i did not come to the white house this evening. >> we have seen that spirit, that patriotism in the crowds that have gathered here outside the white house, people holding candles, waving the flag, singing the national anthem, people proud to live in the united states of america. >> this is a big victory, man, this is symbolic, you know. we have been after this dude for 10 years and here we are, man. >> president obama, he ordered the strike, he got it and i'm proud of our country, proud of our president, proud of our armed forces for going in there. something a national moment of pride. >> a lot of people put their lives on the line like my husband and i mean look at this. >> we are reminded that we are

fortunate to have americans who dedicate their lives to protecting ours. >> i had to be here, this is where i had to be tonight. i had to bring my son with me so we could share this time together. >> we may not always know their names, we may not always know their stories, but they are there every day on the front lines of freedom and we are truly blessed. >> brett haber was one of those who witnessed the jubilant scene last night at the white house. he joins us live from nationals park where it's military appreciation night for this evening's game against the giants. so appropriate, brett. >> reporter: it is appropriate. i was driving home from the capitals game last night at 1:00 in the morning when i stopped by the white house and you would have thought it was 1:00 in the afternoon given the crowds that were out there. i called it a woodstock of patriotism and i think a lot of that sentiment is going to transfer over here to nationals park tonight as you mentioned it is military appreciation night. this is an event the nationals

had planned months ago but i think it takes on a whole new significance given the events that transpired last night. to give you a sense of what's going to go on here today, members of all branches of the armed services will be part of the activities, u.s. army soldiers will throw out the ceremonial first pitch, u.s. marines will deliver the lineup card, the nats starting nine will be escorted to their positions by members of the air force and navy and coast guard and marines and national guards and the nats are donating thousands of tickets to tonight's game to military personnel and their families, washington of course is the epicenter of our military complex, they deserve our acknowledgment every day, but on this day more than most. >> hopefully, you know, we can make this as special of a day for these guys as possible, you know, everyone i'm sure going to be very, very supportive and i'm sure we will probably get a couple of standing over vaithsdz and i'm -- ovations and i'm looking forward to it. >> i don't think it could time out any better.

but it's definitely something that we can't really thank them enough so to have one night here at the ballpark is probably the least we could do for that. >> great opportunity again for our fans to do what we always do, honor our military vets and wounded warriors and i know that those who are here tonight are going to be beaming with pride. >> we say it all the time but we just can't thank you guys enough for allowing us to do this and a lot of times we take it for granted, but you guys are a great reminder of why we are here, so thank you. >> well said by adam laroche. as the news trickled out last night that bin laden had been killed by u.s. forces, there was only one major sporting event going on around the nation, that was the game in philadelphia between the mets and phillies and the reaction there as you can see was quite astounding. people started to see the news on their smartphones and as the 9th inning unfolded chants of u.s.a., u.s.a. started to ring out around the stadium until the entire crowd was doing it, people in the crowd said it was an experience

and we killed the philly fans all the time and i think in this case they got it right. the nationals will unveil their brand-new patriotic uniforms tonight. nice way to pay tribute to the military tonight, all the players will be wearing that. guys, back to you. >> very nice. thank you, brett. up next, the ripple effect of controversial guidelines on screening women for breast cancer. will more tumors be missed? our health alert coming up.

12,807, the nasdaq dropped nine points and the s&p 500 fell two points. the debate on when a woman should start getting screened for breast cancer is heating up again. new research suggests less women in their 40s are getting mammograms after a government panel recommended against screening women. she had her first mammogram at 40. she never expected it would uncover cancer. >> little bit blindsided. >> reporter: under current government recommendations she wouldn't have been screened for years. in 2009 a task force recommended that most women do not need regular mammograms until they are 50 years old. now new research suggests fewer women in their 40s are getting them. a university of colorado study found a drop in mammograms in these women in the nine months after the new guidelines came out. >> we have seen an overall reduction in the proportion of eligible american women who are having annual screening.

this has been a trend and it may be that the trend is now accentuated by these guidelines. >> reporter: it's important to note the american cancer society does not embrace this change and still recommends most women start getting regular mammograms in their 40s, when the disease is often caught in an earlier, more treatable stage. >> strides that we have made in america in reducing the death rate from breast cancer have been in part due to our emphasis on early detection. >> i feel like my case is a perfect example of someone, you know, that is totally healthy and risk-free and yet, you know, did have a cancer. >> to point out why the commission went this way and changed the guidelines, women who start getting their mammograms earlier may encounter more false positives, that is a suspicious spot may be picked up, they get a biopsy, it turns out to be nothing but again that is part of the whole process. thanks for joining us for 9 news now at 5:00. 9 news now at 6:00 starts right
