prayers time for some action president joe biden unveils how he plans to get us gun violence under control. warnings that africa is being left on the margins as countries battle supply problems to get enough covert 19 vaccine. and efforts to restore calm in northern ireland where britain's exit from the e.u. has unsettled a delicate political battles. top story a doctor has emphatically rejected claims that george floyd's drug use and underlying health problems caused his death lung and critical care specialist dr martin tobin testified floyd died from a lack of oxygen while being pinned to the pavement with a knee on his neck now the trial of the former police officer derrick jovan was shown animations of him and 2 other officers holding floyd done during the arrest.

and it's because of the positioning of the handcuffs at the back there and how he's manipulated with the handcuffs by both the officer sharpen and by officer king how they manipulate the handcuffs and they're pushing the handcuffs into his back and pushing them high then on the other side you have the street so the street is playing a crucial part because he's against a hard ass false 3 so the way they're pushing down on his handcuffs combined with the street his left side and it's particularly the left side we see that it's like the left side is in a vise it's totally being pushed in squeezed in from each side. zeros correspondent john hendren joins us live from minneapolis john hi there what else did the experts testify today have to say.

well peter it was day 9 in the murder trial of derek chauvin and it was a red letter day for the prosecution largely because of the man that you see there dr martin tobin he is apparently the guy who wrote what the lancet magazine calls the bible of breathing he's a pulmonologist and he's very well known here in the united states and he was equivocal that the cause of death for george floyd was derek show cutting off the air pipe of george floyd and he went off in some detail at one point he had them freeze frame a shot from the video of one of the police officers badge cameras and in that picture you could see that george floyd had a finger on the pavement and his knuckles on the car the tire of the squad car next

to him he was trying to pull in self up in order to gain breath and this expert said that it was evidence that he he was not able to breathe and he said it's a myth that if you can speak that you can also breathe which is something one of the officer said he said he's ok he's speaking. and he. offered a diagram of the windpipe of the average person and said that a small coin here in the usa he offered the example of a dime. will. we show the with of the windpipe of the average person and he was saying that george floyd had his chest compressed is neck compressed and that eventually he could even pinpoint the point at which he said this is when the life ran out of george floyd so the testimony was really devastating for the defense of the defense lawyer erik nelson has been very effective at cross examinations of each of the prosecution witnesses but in this

case he could not out expert the expert and then you had another couple of experts there was dr william smock who testified that fentanyl did not play a role that's important because the defense theory of the case is that the drugs found in george floyd system fentanyl and opioid and methamphetamine contributed to his death that he possibly had an overdose well this expert was having none of that he went down like 15 items he said which demonstrated that in no case was george floyd showing any evidence of having an overdose and then we had dr daniel eyes in charlotte who went through the drugs that were found in george floyd system and he said the amount of methamphetamine was about the equivalent of one prescribe dose he said that was very little the amount of fentanyl he said was it was less than the average amount found in someone who had it in their system during driving under the influence arrest so really we had

a series of experts in this day of expert testimony really the 2nd day of expert testimony all say that the cause of death was asphyxiation that's interesting because coming up we're going to hear from the official medical examiner who offered the report in which the word as fixation does not appear at all he attribute it to heart stoppage and these experts today said the heart stoppage was caused by derek on george floyd's neck john thank you very much john hendren reporting live for us from minneapolis. now staying in the states he's calling it an epidemic and an international embarrassment now president joe biden has outlined his 1st moves to reduce u.s. gun violence he admits the measures are limited and he will need the support of congress to achieve his ambitious goals as our white house correspondent can really help it. in the absence of meaningful gun control laws passed by congress and in response to recent mass shootings in the states of georgia and colorado u.s.

president joe biden unveiled a series of executive actions to curb gun violence gun violence in this country is an epidemic and it's an international embarrassment the executive actions include regulations on so-called ghost guns weapons assembled from parts that lack serial numbers purchasers of void background checks so when they show up at a crime scene they can't be traced also prohibited pistol stabilizing braces reportedly used by the mass shooter last month in colorado and red flag regulations allowing families to petition the course to confiscate weapons if a person is deemed dangerous i've held hands with the hands of parents who have lost a child gun control advocates see the executive actions as an important 1st step but not enough the notion that somebody can walk down a city street in my hometown richmond virginia whether an assault rifle attached to

their back is just you know unacceptable and unnecessary as a senator biden helped pass legislation to ban assault weapons back in 1994 but it expired 10 years later he's urging congress to act to reinstate the ban the 1904 act had a positive effect on public safety enforcing these actions if confirmed biden's pick to head the bureau of alcohol. all tobacco and firearms david chipman he's a former federal agent but also a gun control advocate making his nomination controversy all with firearm supporters. biden took on his conservative critics arguing his actions do not infringe on a person's 2nd amendment right to bear arms under the u.s. constitution the idea is just bizarre to suggest that some of the things you're recommending are contrary to the constitution the u.s.

president is also calling on congress to pass laws ending immunity for gun manufacturers making it possible for victims of gun violence to sue gun manufacturers in court joe biden calls this one of his top priorities can really help get al-jazeera the white house turkey has condemned comments from the italian prime minister mario draghi who's likened president wretch up time her to one to a dictator turkey's foreign minister has summoned the italian ambassador to explain the remarks druggy accused of humiliating the european commission president on the line she was left without a seat during a meeting in ankara on tuesday. oh no no i'm going to go into the boat it's really a procedure i absolutely disagree with president to one's positions and i think it was inappropriate behavior and i was very sorry for the humiliation that the president of the e.u. commission bunda lion had to suffer

the unions 3215 votes were cast and at the end of vote counting on thursday there were 463 yes votes and 1100 no votes the union base of support you need 1608 yes votes and looking at these numbers it does suggest that we'll probably have what we're calling a final result pretty quickly on friday once vote counting resumes but it's not really going to be final because we're expecting a great deal of wrangling to happen no matter what the result is either from amazon or from the union and in addition of votes. i would just leave the vote deadline was about 9 days ago we really got to the stage because we had a long process where i was on it seems has been objecting to hundreds of votes even being counted in the 1st place so if we got what's called what we're calling a final vote we get that on friday but if the number of ridge of votes that amazon

is contested with would affect the final results then we have to go into a long process then of arbitration of figuring out well should those votes be counted so this could go on for weeks if it's likely to go on for weeks no matter who who wins what we're calling this final vote so this initial level of talking about this idea of amazon unionizing or not you know she has we've all seen and read the stories about how hard amazon workers have to work time toilet breaks that kind of thing you know the story of being an amazon employee behind the headlines on the face of it however it would appear that most of the workers in alabama who are employed by amazon quite happy with that. well it depends on how you interpret these results yes i was there just 2 weeks ago we were talking to workers and the word you kept hearing was dehumanization of being expendable there's such a high turnover of staff and i was on warehouses at one point during the pandemic in november i guess they were hiring $2100.00 workers a day it's quite clear to the workers that the that if if they step out of line of

anything they do displease amazon in any way they can be fired i was talking to a diabetic woman who said that she doesn't want to even check blood sugar levels because you feel she will be fine because every minute you're not packing a crate or box for and i was on customer you are being judged and you're in and it's going down badly with the i was on stuff. it's true though that even when we were there it seemed that the amazon union supporters knew that things were stacked up against them they knew that amazon had pulled out all of the stops they had started mandatory meetings for work because we're talking about the evils of unionizing workers were being bombarded with text messages when you go to the toilet apparently you know you sat in a cubicle you'd have posters telling you that unions unions are evil they would probably be the legendary pinkerton spy agency to monitor workers social media so everyone knew that they 'd were under surveillance in some ways which adds that level of intimidation and there are various points that may come up in litigation

like like apparently supervisors encouraging workers to fill out their union ballots in front of them. and sort of and them and then mail them in a in a in a mail box then suddenly appeared on the amazon campus itself we just had a blockbuster story just today ironically in the washington post owned by jeff jeff bezos which said that was one of pressured the postal service to place that post box on the amazon campus that the national labor relations board did not want to buy the books there because it gives that sense of being watched it also has that sense of amazon has some say in and what happens to the ballots so this will obviously be part of litigation in the future but it has to be said the unions knew that it was an uphill battle but they're already talking about it we've come so far even to think about uniting but we have had hundreds of hundreds of inquiries has around the country they say about you know there was a walk out of the chicago warehouse just on wednesday but look at the statement of this is going to this is

a statement we just got from the president of the union the the i was all workers would join and it hardly sounds like he's claiming victory he says our system is broken and took full advantage of that and we will be calling on the labor board to hold on accountable for its illegal and agreed just behavior during the campaign that hardly sounds like they think they're going to win. thanks very much in every town today in washington. the white house has joined the governments in appealing for calm in northern ireland to trade issues off to brakes it comes together with other frustrations across the province generating some of the worst on rest is his under simmons. a 6th night of violence in northern ireland this is the scene in belfast a bus set on fire the driver escaped shot but not hurt no passengers were on board at least 7 police officers were injured here and more than 50 hurt in less than a week most of the violence had been caused by pro british loyalist rioters angry
