this is bbc news. the headlines: a us teenager who shot dead two people and injured another during racialjustice protests last year has been found not guilty of murder in a trial that polarised america. kyle rittenhouse argued that he was repeatedly attacked, and had acted in self defence. police in the netherlands have fired warning shots during a demonstration by people opposed to the partial lockdown put in place to stop rising covid infections. local media say water cannon was also used to disperse a crowd of several hundred which had set fire to police vehicles. belarus' authoritarian leader alexander lukashenko says he will not stop the flow of thousands of migrants through his country as they try to enter the eu. speaking to the bbc, mr lukashenko admitted his armed forces may actually be helping migrants cross the border into poland.

it's already illegal to call or text on a handheld phone while you're driving in the uk. but from next year, the rules are getting even tighter. drivers will be banned from taking photos, filming, searching playlists or playing games — even while stationary — on mobiles and tablets. those who break the law will face six points on their licence and a £200 fine. caroline davies reports. # happy birthday to you... joe cairns was 1a years old when his mother last waved him off to school. i always told him, you know, "i love ya". not always would he say it back. chuckles. sometimes he would. we got him settled in the van and i waved goodbye to him. the minibusjoe was riding in was hit by a lorry. the lorry driver was checking his social media on his phone moments before the crash. finding that out, i do remember

being physically sick. i was, you know — it was just that reaction that my boy was killed for nothing. for likes, you know? checking his social media. the driverjames majury was jailed for eight years for dangerous driving. the current law bans driving while texting and calling, but this change will mean that it's easier for police to charge drivers holding their phone, regardless of the reason. from next year, there'll be very few exemptions for why you're able to hold your phone while you're driving. one of them will be if you're making an emergency phone call. but another proposed one is if you're paying for something contactlessly — for example, a toll or maybe a drive—through restaurant — but your car has to be stationary. you can still use devices like satnav, for instance, but they have to be in a cradle. the law was introduced in 2003 when calls and texts were what most mobiles were used for. although police can charge drivers with other driving offences if they are
1:33 am
using their phone and not in control of their vehicle, this change will close a loophole. if you get caught now, you're going to get a £200 fine and six points on your licence. that is quite significant. the police will be able to enforce the law is —— the police will be able to enforce the laws much more strongly. joe's family continue to tell his story, to make drivers think again about how and when they use their phones. he had a life — a whole beautiful life to lead. through somebody�*s choice that day, they took his life away. and he is no more. and it has to be out there, it has to be how dangerous it is to use your phone whilst you are driving. caroline davies reporting. now on bbc news, it's time for click.

operation at you could just tell it provided them with that extra bit of reassurance that they felt they were making the right decision. and they knew what to expect from the surgery, and in the weeks that followed, and that really may have given them a little bit more confidence along the way. yeah, absolutely. thank you for telling that story and archie, and yourfamily, lots of telling that story and archie, and your family, lots of love, best wishes from us. hello and welcome to the week in tech. it was the week the fbi is investigating thousands of fake e—mail sent from one of its own servers. startrack discovery fans will now only be able to discover season four if they live in canada or us after netflix lost streaming rights to paramount days before release. and video sharing site youtube announced plans to make dislike numbers private. apple will soon finally let users repair their own phones, selling the tools and parts available some of the common fixes. yes, those of us with the inclination, time and

facebook has had a good few weeks. mostly that is down to francis blowing the whistle on her former employers francis blowing the whistle on herformer employers by francis blowing the whistle on her former employers by leaking thousands of internal documents. the facebook fails, as they are known, reveal the inner workings of the company and james clayton has been wondering whether her testimony along with a new california law might inspire others to come forward as well. people like frances haugen are a rare thing in silicon valley. the decision she made to take on facebook was not taken lightly. the company _ was not taken lightly. tue: company intentionally was not taken lightly. tta: company intentionally hides vital information from the public, from the us government and from governments around the world. ,, . ., and from governments around the world. ,, ., , , ., world. silicon valley is a notoriously _ world. silicon valley is a notoriously secretive - world. silicon valley is a | notoriously secretive and notoriously secretive and notoriously litigious place when it comes to employees who want to put their head above the parapet to raise concerns. how did big tech get so big? 0ne how did big tech get so big? one of the reasons it got so big, to be honest, is by exploiting thousands of people who work there. the way that
1:47 am
they have managed to keep that exploitation going is by silencing people who work there, including through incredibly wide and broad nondisclosure agreements. i have honestly almost never seen anything like it. i am a human rights lawyer who used to bring cases against the cia and the culture of secrecy at big tech is basically as bad as i used to see in the cia. it is basically as bad as i used to see in the cia.— to see in the cia. it means whistleblowers _ to see in the cia. it means whistleblowers who - to see in the cia. it means whistleblowers who want i to see in the cia. it means| whistleblowers who want to to see in the cia. it means - whistleblowers who want to come forward, like haugen, need to be extremely brave and have extremely deep pockets. nondisclosure and non— disparagement agreements have often been used here in silicon valley to try and silence employees. take the notorious case of theronos, for example. behind me are what used to be theronos's very plush offices —— theranos. the company claimed it could diagnose hundreds of diseases with just a few drops of blood. the problem was that that idea was

in behind the front, with a scattering of showers waiting in the winds. that gradually slips its way south into northern ireland and northern england. ahead of it, we should see early—morning cloud, mist and murk starting to thin and break for some glimpses of sunshine and highs of 13 celsius. plenty of showers following into the far north of scotland and already the first signs of that colder air arriving. but the real cold air pushes through saturday night into sunday, and the wind direction changes to this northerly flow. so, for all of us, we'll notice the difference first thing on sunday morning. there'll be more in the way of sunshine right across the country, but it will be noticeably colder, particularly when you factor in the strength and the direction of the wind.
