this is bbc news. welcome if you're watching here in the uk, on pbs in america or around the globe. i'm mike embley. our top stories: a stark warning from president trump that he will deploy the army to end the widespread protests across the country triggered by the death in police custody of the unarmed african american, george floyd. if a city or a state refuses to take the actions that are necessary to defend the life and property of their residents, then i will deploy the united states military, and quickly solve the problem for them. in minneapolis, the official post mortem examination finds the death was a homicide. the victim's brother tells demonstrators violence would not bring the changes the black community deserves. my family is a peaceful family, my family is god fearing.

let's do this another way. let's stop thinking that our voice don't matter, and vote! protests against police brutality continue. at least a0 cities and washington dc have imposed curfews, with a heavy police presence at the white house. moments after he threatened to deploy "thousands and thousands" of us troops against the protests and riots that have engulfed dozens of american cities, president trump has been on an extraordinary walkabout through downtown washington dc. he eventually stopped for photos, holding a bible, in front of the so—called "church of presidents," damaged in the disturbances. a peaceful protest outside the white house was tear gassed by police to clear

the president's path. earlier he'd told state governors they must "dominate" the protests and get "much tougher." the death of george floyd, in minneapolis, which sparked the latest unrest, has now officially been declared a homicide. the following measures are going into effect immediately. first, we are ending the riots and lawlessness that has spread throughout our country. we will end it now. today, i have strongly recommended to every governor to deploy the national guard in sufficient numbers that we dominate the streets. mayors and governors must establish an overwhelming law enforcement presence until the violence has been quelled. if a city or state refuses to take the actions that are necessary to defend the life and property of their residents, then i will deploy

the united states military and quickly solve the problem for them. i am also taking swift and decisive action to protect our great capital, washington, dc. what happened in this city last night was a total disgrace. as we speak, i am dispatching thousands and thousands of heavily armed soldiers, military personnel and law enforcement officers to stop the rioting, looting, vandalism, assaults, and the wanton destruction of property. we are putting everybody on warning, our 7 o'clock curfew will be strictly enforced. those who threaten innocent life and property will be arrested, detained and prosecuted to the fullest extent of the law. i want the organisers of this terror to be on notice that you will face severe criminal penalties, and lengthy sentences injail.

this includes antifa and others who are leading instigators of this violence. one law and order. and that is what it is — one law. we have one beautiful law. and once that is restored and fully restored, we will help you, we will help your business and we will help your family. america is founded upon the rule of law. it is the foundation of our prosperity, our freedom and our very way of life, but where there is no law, there is no opportunity. where there is nojustice, there is no liberty. where there is no safety, there is no future. we must never give in to anger or hatred. if malice or violence reigns, then none of us is free.

i take these actions today with firm resolve and with a true and passionate love for our country. by far our greatest days lie ahead. the official post mortem examination of george floyd has declared his death a homicide as a result of compression to the neck while being restrained. the official report was published shortly after an examination commissioned by the floyd family, concluded he died from asphyxiation. earlier, his brother, terence, spoke at the scene of his arrest. in every case of police brutality, the same thing has been happening. y'all protest, y'all destroy stuff and, if they don't move, nobody don't move, because it's not their stuff, it's our stuff? so they want us to destroy our stuff.

they're not going to move. let's do this another way. terrence floyd there, the brother of george floyd. professor rachael vanlandingham is a retired air force lieutena nt—colonel and security expert at southwestern law school, she joins me from los angeles. thank you very much for your time. lots of people are wondering whether the president can actually do what he is threatening to do, or says he has already started to do. people are talking about the insurrection act of 1807. well, the insurrection act of 18 seven, which replaced the previous militia act, but has not been used in such a situation since president lincoln called forth the militia to put down the so—called insurrection that started and prompted the civil war. so the insurrection act is a mechanism that operates, it

is federal statute, based on congress' constitutional authority under article one. it authorises the president to use federal troops, federal military troops, including, he can federalised the state ‘s national guard is, to enforce domestic law within the united states. but there are three different predicates for using that, for using this authority. first, which is most typical, is at the request of a state, usually the state governor. in 1992 the state governor here in los angeles, where i live, called and requested help from the first president bush to put down the 1992 riots that erupted because of the unfair acquittal, i'm just erupted because of the unfair acquittal, i'mjust acquittal of the killers of rodney king, again, police officers. two, the president can make a determination that rebellion or obstruction of federal law is preventing, or that state authorities themselves are

preventing the compliance of federal law. that is what president eisenhower and president eisenhower and president kennedy relied on, that authority, to enforce segregation and call forth the us military to enforce, excuse me, desegregation, of course, in the late 1950s and early 19605, in the late 1950s and early 1960s, and alabama, mississippi and arkansas. that brings us to the third situation. this is one that we have not yet had in the united states under the insurrection act. that is an authority the president can find that there is some kind of insurrection which is domestic violence or an unlawful combination thereof, which threatens the enforcement of federal law, and deprives citizens of their federal rights, deprives citizens of the total rights. but is rather broad, and i do not think the situation right now has risen to the level of anything like the 1992 riots. for example, in los angeles, in which we had over 2000 individuals seriously injured, 63 people died, almost

4000 fires were set, 1000 buildings destroyed. that was the point at which the governor of california requested for federal forces to of california requested for federalforces to come of california requested for federal forces to come in. of california requested for federalforces to come in. we don't have that in the united states, and what is important to remember is that the state governors have their own local law enforcement, they have the ability to call forth their national guard, the militia, the citizen soldiers can engage in law enforcement and have a long and proud tradition since the founding of this nation of helping enforce domestic law and keep the peace. and state governors, especially after katrina, hurricane katrina in 2005, engaged in and implemented different prostate agreements, so that they can request help from fellow state governors to send those other state national guards and to augment their own. because there is a fear, a deep—seated fear that goes back to the federalist papers, to the founding fathers of the united states, and mothers, of the standing army, the us military, the federal military being

deployed against us citizens. the standing army was always something to be feared as a threat to democracy and it was to be kept small and used for foreign wars, not internal use in the united states. so there isa in the united states. so there is a fear that president trump is a fear that president trump is using this politically, but he is fear mongering and using the military as, essentially, a proper, which does such a horrible disservice and disgrace and deflects from the tragic murder and death of mr floyd and detracts from the alternate message, the issue here, which is institutionalised, systemic racism in the united states, that president trump has u nfortu nately that president trump has unfortunately contributed to and condoned. i'm happy to a nswer and condoned. i'm happy to answer other questions. professor, i will have to ask you to be brief on this one, though i know that these are complicated matters that you have to be precise, deep president is also talking about designating this so—called antifa a terrorist organisation. there are problems with that, aren't there, quite apart from the fa ct there, quite apart from the fact that antifa is not an

organisation? there are huge problems. what he did was meaningless, completely symbolic. it has no legal teeth. under us federal law, and under us supreme court jurisprudence, there is a us federal law that allows the state department or the president to list a foreign terrorist organisation to be a terrorist organisation to be a terrorist organisation, and therefore anyone known to provide material support to such an organisation, that is a crime, a federal crime under us federal law. however, he is not allowed to name any domestic organisation, if antifa, this was collective of seemingly autonomous groups is actually an organisation. nobody can be arrested for belonging to a domestic group. we have freedom of assembly. congress tried to do that during the horrible mccarthy days of anti— communism in the smith act, and the supreme court said, not so fast. it is only allowed for foreign terrorist organisations and there are no indications that this is an organisation or

that this is an organisation or that it that this is an organisation or thatitis that this is an organisation or that it is foreign. therefore nobody can be arrested for a crime in the us for being a so—called member of antifa. they can, however, just like the white aryan brotherhood, or the white aryan brotherhood, or the other white supremacist groups, which have not had president trump label is a terrorist organisation even though they were in cha rlottesville though they were in charlottesville and have been protesting on state capitals on the governors keeping their own people safe, they can be arrested if they actually commita arrested if they actually commit a crime. they can be arrested for the conduct, if they are engaging in assault or battery or property vandalism, or otherwise committing crimes. that is when individuals can be arrested for, not for belonging to an organisation. this is the united states, president trump, andi united states, president trump, and i really hope our courts and i really hope our courts and our law enforcement and our military keep it that way. professor, very briefly, if you can, there are people wondering if what the president is really seeking is martial law. well, if he is seeking it, it is unconstitutional. and i really had the military would say no and say that is an unlawful order. that hope. martial law

is the actual taking of of local governance, taking over the courts, taking over law enforcement. even if he invoked the insurrection act, but does not allow him to engage in martial law, it does not allow the military to engage in martial law. they still have to obey the same rules and constitutional restrictions regarding proper use of force. they can't just regarding proper use of force. they can'tjust go in and start shooting people, because they are engaged in his protest, right? they can arrest people, and if someone poses a serious risk of imminent, and imminent serious risk of deadly or serious risk of deadly or serious harm to an individual, toa serious harm to an individual, to a police officer or a national guardsman, or to a civilian, that is when deadly force can be used. it is the same exact standard as applies to local law enforcement, and to local law enforcement, and to the police, i would sure hope our us military is going to exercise even more self—discipline than what our police have been exercising over the last days and decades and months. professor, thank you so much for your expertise and your insights.

stay with us. much more to come on bbc news. the queen and her husband began their royal progress westminster. the moment of crowning, in accordance with the order of service, by a signal given, the great guns of the tower. tributes have been paid around the world to muhammad ali, who has died at the age of 74. outspoken but rarely outfought, ali transcended the sport of boxing, of which he was three times world champion. he was a real fighter and he fought all the way to the end, even through his illness. yes, he did. uefa imposes an indefinite ban on english clubs playing in europe. today is the 20th anniversary of the release of the beatles' lp, sergeant pepper's lonely hearts club band, a record described as

the album of the century. this is bbc world news, the latest headlines: president trump visits the washington church damaged by protesters, after issuing a stark warning that he will deploy the army to end the demonstrations triggered by the death of the unarmed african—american, george floyd. protests against police brutality are continuing in dozens of cities across the united states, including the nation's capital, washington, where a curfew is now in place. there is broad agreement the us has not experienced such protists since the assassination of martin luther king. again, the deep mistrust

and hostility felt by millions of african american police have been exposed. the words "state of emergency" seem inadequate to describe what's happening in america right now. not since the assassination of martin luther king in 1968 have we witnessed such widespread racial turbulence. chanting: black lives matter, black lives matter! if we render these pictures in black—and—white, they'd look like they came from the 60s. # we are not afraid...#. that was the decade when the struggle for black equality achieved such landmark success. the civil rights movement pushing for legislation that ended segregation across the american south and guaranteeing voting rights for black americans. but there was unfinished business. police brutality has always been hard to legislate against. african—americans have never achieved equality in pay — a form of income segregation that persists today. the racism is a sore that has been festering over and over and over

and over again. and it's like when the sore is about to heal, the wound is reopened again by incidents like this and you have to start all over again. and the question is, how much can people take? cheering many hoped the election of america's first black president would repair, even heal america's racial breach, but barack 0bama never wanted his time in office to be defined by the colour of his skin. in terms of racial progress, his presidency was less historic than the fact that he became president. this american carnage stops right here and stops right now. he was followed into office by donald trump, whose political rise started when he disputed whether ba rack 0bama was born in america — a groundless accusation. many reasons explain his victory in 2016, but mr trump certainly benefited from a backlash against a black president

among some white voters. america is being hit right now by three simultaneous convulsions. a pandemic that's disproportionately affecting people of colour, an economic shock that's disproportionately affecting people of colour and civil unrest caused by police brutality that disproportionately affects people of colour. racial division is america's default setting. so what we're seeing here is not some aberration, but rather the continuation of an unbroken historical thread. nick bryant, bbc news, new york. more reaction to this. i spoke toa human more reaction to this. i spoke to a human rights lawyer who dedicated his career looking at human rights.

i think i think it's a representation of what we've seen throughout history. since we've had people of african descent on what is the soils of when this land was called the united states of america, there's been a history of violence against them. the police we've seen in the streets right now other police that came out in slave patrols so it's another iteration of the same cycle. that's the concern as much as anything, there is the same cycle going on and in the past, this cycle has not changed anything. there must be a worry, mustn't there, among the people protesting, even people who are not involved in the violence or disturbance or any looting, all this plays into the hands of the president who says he is tough as he sees it. all this could help in the election. it may not ring any of the change that the protesters want. well, perhaps. it think the most important thing is that donald trump ran on a campaign of law and order and people have gone into the streets to reject that so he can continue to make calls to the military and deploy the national guard but at the end of the day,

people are sick and tired of watching people, black people especially, with their faces on the pavement, with white officers kneeling on their back, so there's no amount of threat that donald trump can do against people who have already seen that history. before there was donald trump, there was richard nixon, there was ronald reagan. we've had iterations of donald trump who have also been law and order police—focused and have decided to use that against people of colour, poor people, homeless people, queer people, native people. this country was built on using police in order to build—up the capitalist system we have today. so donald trump threatening today, people don't feel intimidated by that because they've had enough. as long as people continue to go into the streets, we will keep ignoring on what he's spewing out of the white house. this is a president who is not known for is empathy, when his inaugural speech talked about american carnage. there must be concerned about what comes next from this president, surely?

sure, the thing is, we don't need an empathetic president, we don't need to rely on donald trump's benevolence to stop the police violence. we can have the most benevolent president in the history of this country but until police officers start losing power, we start shrinking budgets, reducing contact between them and civilians, that's when we get to the heart of the problem. not putting all our hopes and dreams into someone who is the leader of the country and they are nice and empathetic or understand because we had a president who was empathetic to our cause and that did not eliminate the violence of police brutality that we still see today so until we have complete transformational systemic change we can't rely on whether our leaders are nice or sympathetic to our cause. another main story here, people

in england have seen that the biggest relaxation of the lot down. there has been criticism from some scientist that it has occurred too soon. enjoying new freedom in england today to meet outdoors in larger groups with social distancing. the rules in wales changed today as well. scotland and northern ireland have already loosened the guidelines on meeting outdoors. so as the restrictions are eased, how will the authorities monitor the spread of the virus and try to keep it in check? a full testing and contact tracing system is seen as essential. as well as testing people, ministers say tracking down recent contacts of those who test positive will be vital to stopping the spread of the virus. contact tracers have been appointed and the system launched, but already there are concerns. 0ne contact tracer who wanted to be anonymous told us he had been given very little work since the launch last thursday.

we've heard reports from some contact tracers that, since they started work in england last thursday, they've had very little, if anything, to do. what do you think is actually happening with the system? we've hired, as you all know, 25,000 people to work as contact tracers. and the level of incidence of disease has come down. so actually, we have more capacity than we need. this is a good thing. they were pressed for the numbers of people so far contacted and said those figures would be available soon. then there's the r — that's the virus reproduction number. this shows how fast the virus is spreading. anything above one is when an individual is infecting more than one other person. the aim is to keep it below that, which means the virus is receding. the latest official estimate is a range between 0.7 and 0.9,

which doesn't leave much headroom. data on infections and deaths will be closely scrutinised. the daily number of new cases has been falling. the line shows the rolling average — that's the trend — though that does not include people who have not been tested. that's thousands more. the figure for reported deaths has also been coming down steadily, but the rolling average has stalled in the last few days. in the last week or two, we have seen a relatively persistent steadying of the death numbers and a very long tail of this epidemic curve, if you like. we'll be watching closely to see if that is maintained and persistent or if even that increases in coming weeks. an extra 445 deaths have been added to the total because of delayed reporting in previous weeks. 0ne health leader has said this is a dangerous moment — and easing of lockdown measures should be painstakingly slow, as scientists watch developments. hugh pym, bbc news.

a reminder of the main story. moments after threatening to deploy thousands and thousands of us troops against the protesters, president trump has walked out of the white house staging a photo op outside of washington church damaged by protesters. michael carrick, who preached at the wedding of prince harry, has protested at the use of the church and the bible for partisan political purposes. let just show you live pictures from minneapolis. protest against the death of george floyd still going. derek chauvin, the officer dealing on his neck just before chauvin, the officer dealing on his neckjust before he died will appear in court next week,

it has been announced. much more on all the news anytime on the bbc website. hello there. on monday, the temperature reached 28 celsius, and it was the warmest day of the year so far in northern ireland. and whilst it's going to be another very warm day for many today, the outlook is for it to turn much, much cooler. what's happening? well, we've been dominated by high pressure for weeks now, which has brought us the warm and sunny weather. the high is retreating into the atlantic, and to the north of that weather front, there is much cooler air. that cooler air will get swept down across the whole of the country later this week as a northerly wind develops. there is likely to be some rain around as well. now early morning, we've got rain across the far north of scotland. otherwise, it's dry, clear, temperatures typically 8—11. and once any early mist and fog patches clear away from england and wales, it's going to be another sunny, warm day for many places.

but we've got rain in northern scotland, where it's cooler, and we could see showers and cloud developing further south across scotland into the far north of england later, and also potentially in northern ireland. so here, temperatures will be 22 degrees. the highest temperatures are likely to be towards the southeast of england, say, 27 in the london area. it will be as windy as it's been over the past few days also. so we've got cooler air heading ourway. there's also going to be some rain in that cooler air, but it could prove rather hit and miss, and of course there were large parts of the country that were extremely dry during may. and we're uncertain as to how much rain there will be on wednesday across east anglia and the southeast of england. maybe a bit wetter across other parts of england and into wales, and probably largely dry in northern ireland and the western side of scotland. but there will be a stronger northerly wind, which will make it feel cooler everywhere. temperatures are continuing to drop away, probably peaking at 20 degrees in the south east. and those temperatures actually are near—normal, really, for this time of year. given how warm it's been, this is going to be a bit

of a shock to the system. move things to thursday, and those temperatures fall even further, perhaps a few degrees below average for this time in june. and on thursday, there'll be a lot of cloud around. it may not be quite as windy. at one stage, it looked like most of the showers will be in the north. now it looks like the showers are moving further south across england and wales. where is the high pressure by the end of the week? it's here, well away from the uk. we're going to be dominated by low pressure, some stronger winds, some cooler air and still the potential of some showers on friday.

this is bbc news, the headlines: moments after he threatened to deploy "thousands and thousands" of us troops against the protests and riots that have engulfed dozens of american cities, president trump has walked out of the white house to stage a photo—op outside a historic washington church damaged by protesters. the episcopal bishop of dc has said he is outraged at the use of the church as a political prop. protests against police brutality and the death of george floyd in minneapolis are still going on, despite more than 40 curfews. the official post mortem examination has declared mr floyd's death a homicide. derek chauvin, the officer kneeling on his neck before he died, will appear in court next week. the music industry is to observe a day—long blackout on tuesday, in response to george floyd's death. a number of major record labels, have announced they are suspending business, and working with communities to fight racial inequality. some artists have also cancelled radio appearances and media interviews.
