Three years ago in Detroit, Robert Williams arrived home from work to find the police waiting at his front door, ready to arrest him for a crime he hadn’t committed.
Facial recognition technology used by officers had mistaken Williams for a suspect who had stolen thousands of dollars worth of watches.
The system linked a blurry CCTV image of the suspect with Williams in what is considered to be the first known case of wrongful arrest owing to the use of the AI-based technology.
The experience was “infuriating”, Mr Williams said.
“Imagine knowing you didn’t do anything wrong… And they show up to your home and arrest you in your driveway before you can really even get out the car and hug and kiss your wife or see your kids.”
Mr Williams, 45, was released after 30 hours in custody, and has filed a lawsuit, which is ongoing, against Detroit’s police department asking for compensation and a ban on the use of facial recognition software to identify suspects.

There are six known instances of wrongful arrest in the US, and the victims in all cases were black people.
Artificial intelligence reflects racial bias in society, because it is trained on real-world data.
A US government study published in 2019 found that facial recognition technology was between 10 and 100 times more likely to misidentify black people than white people.

This is because the technology is trained on predominantly white datasets. This is because it doesn’t have as much information on what people of other races look like, so it’s more likely to make mistakes.
There are growing calls for that bias to be addressed if companies and policymakers want to use it for future decision-making.
One approach to solving the problem is to use synthetic data, which is generated by a computer to be more diverse than real-world datasets.
Chris Longstaff, vice president for product management at Mindtech, a Sheffield-based start-up, said that real-world datasets are inherently biased because of where the data is drawn from.
“Today, most of the AI solutions out there are using data scraped from the internet, whether that is from YouTube, Tik Tok, Facebook, one of the typical social media sites,” he said.
As a solution, Mr Longstaff’s team have created “digital humans” based on computer graphics.
These can vary in ethnicity, skin tone, physical attributes and age. The lab then combines some of this data with real-world data to create a more representative dataset to train AI models.
One of Mindtech’s clients is a construction company that wants to improve the safety of its equipment.
The lab uses the diverse data it has generated to train the company’s autonomous vehicles to recognise different types of people on the construction site so it can stop moving if someone is in their way.

Toju Duke, a responsible AI advisor and former programme manager at Google, said that using computer-generated, or “synthetic,” data to train AI models has its downsides.
“For someone like me, I haven’t travelled across the whole world, I haven’t met anyone from every single culture and ethnicity and country,” he said.
“So there’s no way I can develop something that would represent everyone in the world and that could lead to further offences.
“So we could actually have synthetic people or avatars that could have a mannerism that could be offensive to someone else from a different culture.”
The problem of racial bias is not unique to facial recognition technology, it has been recorded across different types of AI models.

The vast majority of AI-generated images of “fast food workers” showed people with darker skin tones, even though US labour market figures show that the majority of fast food workers in the country are white, according to a Bloomberg experiment using Stability AI’s image generator earlier this year.
The company said it is working to diversify its training data.
A spokesperson for the Detroit police department said it has strict rules for using facial recognition technology and considers any match only as an “investigative lead” and not proof that a suspect has committed a crime.
“There are a number of checks and balances in place to ensure ethical use of facial recognition, including: use on live or recorded video is prohibited; supervisor oversight; and weekly and annual reporting to the Board of Police Commissioners on the use of the software,” they said.
Donald Trump has agreed to send “top of the line weapons” to NATO to support Ukraine – and threatened Russia with “severe” tariffs if it doesn’t agree to end the war.
Speaking with NATO secretary-general Mark Rutte during a meeting at the White House, the US president said: “We’ve made a deal today where we are going to be sending them weapons, and they’re going to be paying for them.
“This is billions of dollars worth of military equipment which is going to be purchased from the United States, going to NATO, and that’s going to be quickly distributed to the battlefield.”
Weapons being sent include surface-to-air Patriot missile systems and batteries, which Ukrainehas asked for to defend itself from Russian air strikes.
Mr Trump also said he was “very unhappy” with Russia, and threatened “severe tariffs” of “about 100%” if there isn’t a deal to end the war in Ukraine within 50 days.
The White House added that the US would put “secondary sanctions” on countries that buy oil from Russia if an agreement was not reached.
Later on Monday, Ukrainian leader Volodymyr Zelenskyy thanked Mr Trump and said he was “grateful” for the US president’s “readiness to help protect our people’s lives”.
Analysis: Will Trump’s shift in tone make a difference?
As ever, there is confusion and key questions are left unanswered, but Donald Trump’s announcement on Ukraine and Russia today remains hugely significant.
His shift in tone and policy on Ukraine is stark. And his shift in tone (and perhaps policy) on Russia is huge.
After criticising Vladimir Putin’s “desire to drag it out”, he said he appreciated “preparing a new decision on Patriots for Ukraine” – and added Kyiv is “working on major defence agreements with America”.
It comes after weeks of frustration from Mr Trump over Mr Putin’s refusal to agree to an end to the conflict, with the Russian leader telling the US president he would “not back down”from Moscow’s goals in Ukraine at the start of the month.

Trump threatens Russia with ‘severe’ tariffs’
During the briefing on Monday, Mr Trump said he had held calls with Mr Putin where he would think “that was a nice phone call”, but then “missiles are launched into Kyiv or some other city, and that happens three or four times”.
“I don’t want to say he’s an assassin, but he’s a tough guy,” he added.
After Mr Trump’s briefing, Russian senator Konstantin Kosachev said on Telegram: “If this is all that Trump had in mind to say about Ukraine today, then all the steam has gone out.”
Meanwhile, Mr Zelenskyy met with US special envoy Keith Kellogg in Kyiv, where they “discussed the path to peace” by “strengthening Ukraine’s air defence, joint production, and procurement of defence weapons in collaboration with Europe”.
He thanked both the envoy for the visit and Mr Trump “for the important signals of support and the positive decisions for both our countries”.
As ever, there is confusion and key questions are left unanswered, but Donald Trump’s announcement on Ukraine and Russia today remains hugely significant.
His shift in tone and policy on Ukraine is stark. And his shift in tone (and perhaps policy) on Russia is huge.
Ever since Mr Trump returned to the White House he has flatly refused to side with Ukraine over the Russian invasion.
He has variously blamed Ukraine for the invasion and blamed Joe Biden for the invasion, but has never been willing to accept that Russia is the aggressor and that Ukraine has a legitimate right to defend itself.
Today, all that changed. In a clear signal that he is fed up with Vladimir Putin and now fully recognises the need to help Ukraine defend itself, he announced the US will dramatically increase weapons supplies to Kyiv.

But, in keeping with his transactional nature and in a reflection of the need to keep his isolationist “America-First” base on side, he has framed this policy shift as a multi-billion dollar “deal” in which America gains financially.
American weapons are to be “sold” to NATO partners in Europe who will then either transfer them to Ukraine or use them to bolster their own stockpiles as they transfer their own existing stocks to Kyiv.
“We’ve made a deal today,” the president said in the Oval Office. “We are going to be sending them weapons, and they are paying for them. We are manufacturing, they are going to be paying for it. Our meeting last month was very successful… these are wealthy nations.”

What will Trump’s weapons deal mean for Ukraine?
This appears to be a clever framing of the “deal”. Firstly, America has always benefited financially by supplying weapons to Ukraine because much of the investment has been in American factories, American jobs and American supply chains.
While the details are not entirely clear, the difference now appears to be that the weapons would be bought by the Europeans or by NATO as an alliance.
The Americans are the biggest contributor to NATO, and so if the alliance is buying the weapons, America too will be paying, in part, for the weapons it is selling.
However, if the weapons are being bought by individual NATO members to replenish their own stocks, then it may be the case that the US is not paying.
NATO officials referred all questions on this issue to the White House, which has not yet provided clarity to Sky News.
It is also not yet clear what type of weapons will be made available and whether it will include offensive, as well defensive, munitions.

Will Trump’s deal make a difference?
A key element of the package will likely be Patriot missile batteries, 10 to 15 of which are believed to be currently in Europe.
Under this deal, it is understood that some of them will be added to the six or so batteries believed to be presently in Ukraine. New ones would then be purchased from US manufacturers to backfill European stocks. A similar arrangement may be used for other weapons.

The president also issued the Russian leader with an ultimatum, saying that Putin had 50 days to make a peace deal or else face 100% “secondary tariffs”. It’s thought this refers to a plan to tariff, or sanction, third countries that supply Russia with weapons and buy Russian oil.
This, the Americans hope, will force those countries to apply pressure on Russia.
But the 50-day kicking of the can down the road also gives Russia space to prevaricate. So, a few words of caution: first, the Russians are masters of prevarication. Second, Trump tends to let deadlines slip. And third, we all know Trump can flip-flop on his position repeatedly.

‘Trump sides with the Ukrainian cause’
Maybe the most revealing aspect of all this came when a reporter asked Mr Trump: “How far are you willing to go if Putin sends more bombs in the coming days?”
“Don’t ask me questions like that…”
Mr Trump doesn’t really know what to do if Mr Putin continues to take him for a ride.
Mr Biden, before him, supplied Ukraine with the weapons to continue fighting.
If Mr Trump wants to end this, he may need to provide Ukraine with enough weapons to win.
But that would prolong, or even escalate, a war he wants to end now.
An X account for the Sesame Street character Elmo has been targeted by an unknown hacker who posted antisemitic and racist messages.
The profile is followed by more than 650,000 users on the social network – and usually posts upbeat and motivational updates.
Sunday’s messages, which have since been deleted, called for violence against Jews, insulted Donald Trump, and referred to alleged files related to Jeffrey Epstein.
In a statement, Sesame Workshop said the X account has now been secured – and described the posts uploaded to Elmo’s page as “disgusting”.
This is the latest controversy to befall Elon Musk’s platform in recent days.
Last week, X’s AI chatbot Grok also produced content with antisemitic tropes, which were later removed and denounced as “inappropriate”.
Musk purchased the website, formerly known as Twitter, back in 2022 – with extremist content increasing against a backdrop of less moderation.

The Anti-Defamation League, a US organisation that fights antisemitism, said: “It’s appalling that Elmo’s official account, known for spreading kindness, was hacked solely to spread violent antisemitism.”
“Antisemitism on social media fosters the normalisation of anti-Jewish hate online and offline – and contributes to an increasingly threatening environment for Jewish people everywhere.”
