But is it better to keep boris in the tent or kick him out . Get in touch with us using beyond one hundred days. Hello and welcome. Im katty kay in washington and Christian Fraser is in london. Tucson, newtown, San Bernardino, orlando, and now add las vegas to that list. Once again, dozens of families are grieving. Last nights mass shooting at a concert on the vegas strip has already earned the really grim distinction of being the worst in american history. And 12 hours later theres still no indication of motive. 64 year old Stephen Paddock was a retired accountant who lived on a golf course. On thursday, he checked into the Mandalay Hotel and into a room with a perfect view of the concert venue below him. Hed brought with him more than ten rifles. Last night, from his elevated position, he fired his automatic weapon on a huge crowd below him. We have no idea why. James cook begins our coverage. In the cold nevada desert, Country Music is warming the crowd. The time is 10. 08pm. Gunfire the crowd, 22,000 strong, is uncertain. It takes a moment, a deadly moment, before they realise they are under attack. Gunfire by now, a second round of bullets is raining down. There is a pause. The gunman is reloading again. He is high above them in a hotel. Panic follows, a scramble to live. We hit the ground and just lay there and hung onto each other. Fired another 30 rounds. And then quiet. And then what we were doing was that every time he stopped and was reloading, we got up. Then he started shooting again and we hit the ground. By now, this seems that are at once urgent and familiar. They are americans, and they know the drill. Run. One woman found refuge behind some vending machines. We were sitting ducks. You could hear the bullets coming closer. Then it would get quiet and he would reload. And then they would start going again. There was a girl standing right behind me, about two feet, and she got shot in the stomach. Everybody thought at first it was just firecrackers. And then everybody. It kept going more and more. We felt the shots and then we ran to the hangar, to the airport. And we just kept running. It was. Once we got out the back, we started seeing the people that were shot and the people that were dead. Thats when it hit me, that this was real. Police now know the gunman is in the hotel. Explosives ready, they prepared to go in. He is dead, apparently having taken his own life. And he has left a city in chaos. The hospitals are overwhelmed. There are not enough ambulances. We need to get people to the hospital, ok. With hundreds wounded, a desperate call rings across the airwaves. Please donate blood. There were people hiding underneath my car for cover. There was a gentleman that was shot, and he said, can you help me . I put him in my car. I had six people in my car. People without shoes, running just to get away. There is other urgent work, identifying the gunman. He was Stephen Paddock, a 64 year old man from mesquite, an hours drive from the las vegas strip. He checked into the hotel on thursday. As far as his history and background, we havent completed that part of the investigation yet, but we located numerous firearms in the room he occupied. The president has been in office for less than a year, but he knows the drill as well. It was an act of pure evil. The fbi and the department of Homeland Security are working closely with local authorities to assist with the investigation, and they will provide updates as to the investigation and how it develops. For a western democracy, the United States has seen an astonishing amount of horror like this. But even here, this is carnage on a different scale. Americas mass shooting disease now feels like a plague. James cook, bbc news, las vegas. Our north america correspondent james cook reporting there from las vegas. Weve been speaking to james for the latest. James, at least 58 people dead, 500 have been injured. The numbers are staggering. What are you hearing from hospitals there . The numbers are staggering, as you say. This attack, which happened just next to Mccarran International airport, with the gunmen shooting from the Mandalay Bay Hotel just the gunmen shooting from the Mandalay Bay Hoteljust there, has left this city completely stunned. The hospitals have been struggling just to treat those who are wounded, and certainly the Ambulance Service was overwhelmed and last night. We saw that there were queues of ambulances rushing to the hospital, and people just couldnt get to an ambulance, some of them. They were loading sometimes two or three critically wounding people into the back of cars, commandeering vehicles to get them the treatment they desperately needed. Its the scale of this that is so stunning. We have seen, im sorry to say, so many massacres before in the us, but the scale of this one is just terribly breathtaking. Another thing that strikes me, having reported on so many of these, if that usually 12 hours later there are some sort of red flags that emerge about the shooter. There seems to be nothing about him in this case. Its interesting. 64 years old, a retired accountant, we are told. Somebody who liked flying and had a pilot s licence. He was living out his life ina licence. He was living out his life in a retirement home about an drive from here. Police there say they have not had any significant interaction with him at all. People seem to be talking about a quiet character. Perhaps there was something wrong with him that we didnt know about, something may just have slipped inside him. Police are saying they do not know of any links to any International Terrorist organisations. They are describing this as a lone wolf attack. The fbi is taking the lead in trying to determine what drove him to do it, if indeed we can ever fathom that. In his last text his brother, it was extraordinarily mundane, asking about the welfare of his mother and what he was up to. We know he was in this hotel since thursday. Thats right. He apparently checked into the hotel on thursday. We know he had an incredible cache of weapons in that room on the 32nd floor, from where he was spraying bullets onto the defenceless crowd below. More than ten weapons, clearly a huge amount of ammunition as well. The survivors have talked of how the gunfirejust kept survivors have talked of how the gunfire just kept going. Survivors have talked of how the gunfirejust kept going. He survivors have talked of how the gunfire just kept going. He would reload and it would keep going, again and again. Really, itsjust been a terrifying and horrific experience for those people there. They are rarelyjust beginning to come to terms with what happened to them last night. I have seen people Walking Around this city dazed. James cook in las vegas for us. So here we are, once again, returning to the tragically familiar debate over gun deaths in the United States. The president , who has been a staunch defender of gun ownership, blamed pure evil but his speech was as notable for what it didnt include as what it did. There was no reference to terror or to gun laws. The former secretary of state, john kerry, echoed the view of many outside america when he wrote this. Our north america editor, jon sopel, has been looking at the reaction. America has been on alert for an act of terror, but not from someone like this. A 64 year old white man living in a retirement community, who liked to gamble and enjoyed Country Music. But what turned Stephen Paddock into americas deadliest mass killer is still a mystery. There is not even anything i can say. Imean. How do you. I mean, my brother did this. This is like it was done, like he shot us. If he had killed my kids, i couldnt be more dumbfounded. From the white house this morning, the president sought to bind the wounds of a nation. In moments of tragedy and horror, america comes together as one. And it always has. Until now, the worst shootings were a nightclub attack in orlando, where omar mateen killed 49 people in an act inspired by so called Islamic State. Before that were the killings at Virginia Tech university, where 32 people were killed. But in terms of shock, surely nothing eclipses sandy hook in connecticut, where 25 six and seven year olds were killed at their elementary school. An act of brutality so shocking that it moved the then president to tears. They had their entire lives ahead of them. Birthdays, graduations, weddings. Kids of their own. Today, the two senators from connecticut sought to reopen the age old debate on gun control. Chris murphy saying. While senator Richard Blumenthal said the gun industry in america is huge. But so are the numbers of deaths. Some 30,000 die each year from gunshot wounds. Yes, some are accidental, and many are suicide, but a large number of homicides, too. However, the all powerful gun lobby, the National Rifle association, has been successful in warding off moves to tighten up gun ownership laws. And in President Trump, they have a true friend. As your president , i will never ever infringe on the right of the people to keep and bear arms. Never, ever. Cheering and applause in his address to the nation, donald trump said the American People would be seeking explanations. But the one issue he didnt touch upon was whether gun control could have played a part. The nra believes the way you stop a bad man with the gun is to have a good man with a gun. But how that would have helped in the circumstances of las vegas last night, is anyones guess. Jon sopel, bbc news, washington. We are going to look at different parts of this awful story but were going to start with the investigation. Michael bouchard is the former assistant director at the bureau of alcohol, tobacco and firearms. Hejoins me now in the studio. Let me start with that reportjust there. I was down at Virginia Tech andi there. I was down at Virginia Tech and i remember people there, people saying that if there had been people with guns, it could have been prevented. But in this case, it couldnt have been prevented with people with a gun on the ground. Couldnt have been prevented with people with a gun on the groundm couldnt have been prevented and less somebody had a gun in the room with him or outside the door. It took more enforcement several minutes to ascertain where the shots we re minutes to ascertain where the shots were coming from, put the forces together, and unfortunately he committed suicide. You do courses on active shooter situations. Youve seen the evidence that has come out of las vegas. What do you make of what happened there . One of the first things i teach is situational awareness. Always have an escape plan, no matter where you are. One of the things we are going to learn from this scenario, unfortunately a lot of people were killed or injured, and some of them could have escaped unharmed had they not hit the ground automatically and just fled. You hear run, fight, flight, but in this case running was the only option they had. On the video, you hear they were told to get down. That was the only option they had. At group level, its hard. Once you know shots are coming from up above, laying on the ground, you are a stationary target. People will recognise that you can secure the venue, this concert, and the immediate perimeter, but what you cant do is police in a hotel like that, which has thousands of guests a week, what people are bringing into the hotel. Right. This is a soft target. The guard is down. People are having a good time. No one in their right mind would think shots would be fired from a quarter ofa mile shots would be fired from a quarter of a mile away or more from a room ina of a mile away or more from a room in a hotel, so this brings it to another level. We can keep securing venues, but the criminals keep thinking of other ways to get soft targets. They keep moving outward. You can set up a perimeter, and they will set themselves up outside the perimeter. So its very difficult. The brothers are in that report said, in the extended interview, said, in the extended interview, said that you should go out and find out who sold him those weapons. How likely is that . Atf is researching where these weapons came from. They are certainly going to find out where they bought the firearms. If they bought them from a federal firearms licence fee, they will probably know that today. If you bought them from a private sale, where there are no records, that will be more difficult to try to reconstruct who had the firearms before him and how they got into his hands. Michael bouchard, thank you for coming in. Lets bring in the Counter Terrorism and intelligence expert, matthew levitt, of the washington institute. It does seem this has been ruled out by the fbi as an act of terrorism, oi by the fbi as an act of terrorism, orforeign terrorism by the fbi as an act of terrorism, or foreign terrorism at least. How can they do that so quickly . Its clear that they found quite quickly that this was a loan attacker. When the Islamic State claimed responsibility, this was just the Islamic State trying to remain releva nt as Islamic State trying to remain relevant as it faces defeat on the battlefield. It has about as much legitimacy as claiming responsibility for recent hurricanes. In a case like this, you are able to run down quite quickly who the individual was, who his girlfriend was, where he came from, how long hed been in the hotel, what his background was. We will know more details about how they felt comfortable saying that in the next few days, but it is not surprising. Is the debate over whether this was foreign terrorism oi whether this was foreign terrorism or domestic terrorism a relevant debate, or a relevant part of the investigation . Its relevant to the policy debate. First, there are some in this administration who think that the primary threats to the us is from abroad, from international terrorism. We have had domestic terrorism. We have had domestic terrorism in the past, but it isnt the primary threat. We need to come to terms with the fact that we need to terms with the fact that we need to deal with problems of every kind, domestic orforeign. To deal with problems of every kind, domestic or foreign. We to deal with problems of every kind, domestic orforeign. We have laws on the books that enable us to deal with international terrorism, but we dont have parallel laws to deal with domestic terrorism. We designate groups as global terrorist entities, which gives us authorities to prosecute people, for example for Material Support terrorism. We dont have parallel laws for domestic terrorism. When we think of how to counter violent extremism in this country, we are not ready to tackle every aspect of that, for example people who have Mental Health problems who commit actions like this. We need to get our heads run all of this. The threat is there. The fbi director told Congress Last week that there are around 1000 domestic into vested investigations, as many as they are looking at internationally. Are the fbi constantly looking at the domestic threat . Absolutely. The comments were new and important. In the past the fbi have talked about 1000 cases related to the Islamic State across all 50 states. The fact there is at least as many domestic cases should be a wake up call for policymakers and the public. We are not at the point yet where most people, including many in the administration, are willing to accept that this is a crisis we are facing domestically. As i have said previously, take for example the travel ban. There may be reasons to have the travel ban, but not because it isa have the travel ban, but not because it is a terrorism concern. So far the people who have come from abroad and carried out terrorism in the United States were not radicalised before they got here. Radicalisation happens here in the us both from an international and domestic perspective. The total number of guns in the us is thought to be around 300 million. Gun deaths are rising to more than 15,000 last year. This year there have been over 11,000. Add all of those deaths together, and you will see there have been over 52,000 since the start of 2014. That is more than the total death toll of Coalition Troops in afghanistan and iraq since the war began in 2001. More civilian deaths this year than the number who died at war in 16 years. Well, gun ownership is an important political issue in the us. Ron christie is the former advisor to president George W Bush and is in san francisco. It is very hard for people outside the country to look at what happened in las vegas and think that the conversation in america wouldnt today all be about gun control. Weve been through this before and weve seen that the laws dont change. Good afternoon. Thats exactly right. Our hearts and our prayers and our deepest sympathies for those who have been killed by this senseless tragedy and those who are recovering. Inevitably, there will be conversations in congress and among the Political Class who will be saying, can statutes be enacted and laws be put forth that can put forward a sensible solution . U nfortu nately, can put forward a sensible solution . Unfortunately, i dont believe laws are going to do this. It is the hearts and minds of people rather than specific legislation that will prevent tragedies like this happening again. But the counterargument would be that australia and uk were changed gun laws and reduce the number of mass attacks in those countries because of those laws. Are you saying laws would make no difference . There are sensible steps. We could have universal background checks to ensure that those who are legal able to purchase five rounds have an investigation behind them. Purchase firearms. The
