A place where people usually come to enjoy themselves is now a focus for a community's grief and anger.

It's cordoned off to traffic, and a steady stream of people arrive to place candles and flowers, trying to come to terms with what happened here.

I've now seen four angles of this shooting - four different videos which show the fatal shots, the moments before and the moments after.

They offer a window into how this horror unfolded, second by second. Obviously, there's a lot we can't see, particularly given the crush of federal agents surrounding Alex Pretti in the final seconds of his life.

There's a lot we don't know about the perspectives of the protagonists and what they were thinking. It's noisy, it's chaotic, and several people in the videos are wearing very similar clothing.

But to be crystal clear - at no point is there any obvious evidence, even a hint, that Mr Pretti was intent on massacring a group of immigration agents in broad daylight, as the Department of Homeland Security is claiming.

At no point is there any sign that this situation will escalate to the point where a man will be shot dead.

'He is on his knees when first shot is fired'

A video filmed by a bystander on the pavement, yards from the incident, shows Mr Pretti filming the immigration officers on his mobile phone.

In recent weeks, many people in Minneapolis have been following federal immigration agents around the city and recording their activities, amid allegations they are abusing their power in a furious drive to enforce US President Donald Trump's migrant crackdown.

It is not a crime to follow and record federal agents. Some of the people who have done this told me that not only is it their First Amendment right to do so, but that they feel it is their civic duty.

In the videos of the shooting of Mr Pretti, you can see and hear people blowing whistles. Again, many people in Minneapolis have been blowing whistles and beeping car horns to warn their neighbours that immigration officers are active in the area. It is not a crime to do that either.

At one point, Mr Pretti appears to be trying to direct traffic down the road, waving at a car to go around him. If he was intent on a massacre, he had plenty of opportunity to open fire as ICE officers had their backs turned to him.

A few seconds later, an officer seems to push a woman and Mr Pretti intervenes.

He is pepper-sprayed and goes to the ground.

It's not clear why officers used the pepper spray or if they warned him first.

He is on his knees when the first shot is fired and seems to be motionless when at least nine more shots are fired.

At no point does he appear to be holding a firearm, and certainly not pointing it at anyone.

'Situations can quickly escalate'

I'm not particularly surprised something like this has happened again, just over two weeks after the killing of Renee Nicole Good.

I've been to Minneapolis on three separate occasions this month and each time have seen how situations involving federal immigration agents can quickly escalate.

I was a passenger in a car with a woman "observing" ICE officers, not dissimilar to what both Mr Pretti and Ms Good seemed to be doing.

Their first interaction with her was to bang on her windows and threaten to smash them. They then threatened to throw her in jail but did not say what crime she was suspected of.

All of this was before they even asked her name.

The normal rules of engagement have been thrown out of the window here.

I've also seen how the Trump administration has jumped to conclusions and demonised victims caught up in protests against ICE.

Last week, protests erupted following the shooting of a Venezuelan man by an ICE agent in northeast Minneapolis. I was there as law enforcement fired tear gas at the crowd of protesters who gathered late into the evening.

Another 'terrifying ordeal'

I then interviewed a very distressed father, Shawn Jackson.

He had been returning from watching a basketball game with his six children, ranging in age between six months and 11 years.

They had become enveloped in the protests, and a law enforcement officer threw a tear gas canister under their car. It exploded, mimicking a crash, meaning the airbags inside the SUV inflated and it quickly filled with tear gas.

Mr Jackson told me everyone in the car was gasping for breath, that his six-month-old had completely stopped breathing, and all of his children were taken to hospital.

They are thankfully physically okay, but it was a terrifying ordeal.

The Department of Homeland Security posted a link on X to an interview with Mr Jackson discussing this awful situation and added the comment: "It is horrific to see radical agitators bring children to their violent riots. PLEASE STOP ENDANGERING YOUR CHILDREN."

They later deleted the comment, presumably after discovering the reality of the circumstances.

But it was a reminder of how dangerous it is to leap to conclusions.

And with the death of Mr Pretti, once again an investigation into a shooting by a federal immigration agent here is being predetermined by the White House.

Warning: Some readers may find the content in this article distressing

Alex Pretti, an intensive care unit nurse, was sprayed with irritants before being shot at least 10 times in just five seconds on Saturday.

In a statement, Mr Pretti's family said the nurse, who cared for US veterans at the Minneapolis VA hospital, was a "kind-hearted soul who cared deeply for his family and friends".

They added: "The sickening lies told about our son by the administration are reprehensible and disgusting. Alex is clearly not holding a gun when attacked by Trump's murdering and cowardly ICE thugs."

Instead, they say both his hands were visible and that he had been trying to protect a woman who had been pushed by federal officers.

However, those claims have been contested by key figures of Donald Trump's administration.

Hundreds of demonstrators have gathered for a vigil despite freezing conditions in Minneapolis after the shooting.

Tensions had already been riding high in Minneapolis over the presence of immigration and customs officers following the fatal shooting of 37-year-old Renee Good in the city weeks earlier.

After the shooting of Mr Pretti, an angry crowd gathered and protesters clashed with federal immigration officers, who wielded batons and deployed flash bangs.

Information about what led up to the shooting was limited, Minneapolis Police Chief Brian O'Hara said - but politicians and officials are already visibly polarised over this latest fatal incident.

The Minnesota National Guard was assisting local police at the direction of Minnesota governor Tim Walz, officials said.

Minneapolis mayor Jacob Frey has asked for National Guard troops to work with police, but has said they will wear reflective vests to "distinguish them from other agencies".

Governor Walz called on Mr Trump to "pull the thousands of violent, untrained officers out of Minnesota. Now".

"Minnesota has had it," he added and described the situation as "sickening".

However, the Department of Homeland Security (DHS) said Mr Pretti was carrying a semi-automatic handgun and two magazines of ammunition, and implied he "wanted to do maximum damage and massacre law enforcement".

In bystander videos of the shooting that emerged soon after, Mr Pretti is seen with a phone in his hand, but no footage appears to show him holding a visible weapon.

Mr O'Hara said police believe the man was a "lawful gun owner with a permit to carry".

Border Patrol commander Greg Bovino said at a news conference that federal law enforcement had been under "constant attack" in Minneapolis for weeks.

In an X post that was reposted by Mr Trump, DHS assistant secretary Tricia McLaughlin claimed that a protester in Minneapolis had allegedly "bit off" an officer's finger.

The post included graphic images of what appear to be the bloody wound.

Attorney general Pam Bondi said a suspect had been arrested and was in custody over the incident.

Mr Trump also shared an image on social media of the gun immigration officials said was recovered and described Mr Pretti as a gunman.

Writing online, he said: "This is the gunman's gun, loaded (with two additional full magazines!), and ready to go - What is that all about?".

DHS secretary Kristi Noem also questioned why Mr Pretti was armed in a news conference but did not say that he had drawn his weapon or brandished it at officers.

Robert Alver, who worked with Mr Pretti in a university science lab almost 17 years ago, described him as "everything you would want in a colleague and a friend".

Fighting back tears, Mr Alver criticised Ms Noem's comments, saying: "There is no way on God's green Earth that he would ever be going anywhere to hurt somebody. He would had to have had a complete personality transplant."

Mr Trump has accused the city's Democratic governor and mayor of "inciting insurrection, with their pompous, dangerous, and arrogant rhetoric".

Mr Pretti was shot just over a mile from where an immigration federal officer shot and killed Ms Good on 7 January, an incident which sparked widespread protests.

The independent police watchdog is investigating how South Yorkshire Police mixed up the identities of 17-year-old Trevor Wynn and 18-year-old Joshua Johnson after a crash in Rotherham in December.

For three weeks Trevor's family believed he had died, while Joshua's sat by the bedside of the injured victim in hospital. When he regained consciousness, the truth became clear.

"It's hard to imagine what these families have been through in the past few weeks," said Emily Barry, the director of the Independent Office for Police Conduct. "It is clear something has gone very wrong with awful consequences for them."

But it turns out the case is far from unusual.

George Crawford had picked up the wallet his friend had left behind in a takeaway on a night out in October 2018.

When 20-year-old George was hit by a car in the early hours, police identified him through that friend's ID and the wrong family was summoned to the hospital.

By the time the mistake was uncovered, it meant George's family were not with him when he died.

"We could have been at the bedside of our son to say goodbye and we had that removed because somebody did not do their job correctly," said George's father Cameron.

Choking back tears, he added: "To see it happening again, my heart bled for both of sets of families."

More details have emerged about how the Rotherham case unfolded.

At the scene, police found a phone in a case which also contained Joshua's driving licence. A second phone nearby showed some medical ID information and was in the name of Trevor.

An officer spoke to Trevor's mother, who provided his college ID and a description of his build and footwear. The officer compared that to the body in the mortuary and "was satisfied that this was" Trevor.

A second officer in the ambulance with the surviving teenager had been told by other officers it was Joshua. Looking at the photo on his driving licence, with medical staff, they agreed it was him.

But when that injured teenager regained consciousness, Joshua's father alerted the police to the misidentification.

Misidentification 'incredibly easy'

Lucy Easthope is one of the country's leading disaster recovery experts and has long campaigned for more attention to be given to avoiding misidentification.

She said the Rotherham incident should be a "stop and think" moment for authorities.

A professor at the University of Bath's Centre for Death and Society, she said she has been present at incidents when a mistake has been spotted.

"The world just falls out from beneath your feet," she said.

"I think we think that the worst thing that could've happened is the thing that happens, but actually we can continue to do even more harms as responders, and not returning the right person to the right family is one of those additional harms."

Prof Easthope said she hears from police officers who feel pressured to make an identification through documents found at the scene that should not be accepted.

"The living person has woken up and that should not be the safeguard," she said.

"It's actually incredibly easy for misidentification to occur. We have to fight every day to make sure we don't incorrectly identify people.

"For me, this is a real clarion call about improving resource and awareness."

George Crawford's family have turned the pain of his loss into a charity in his name "to give young people a leg up to realise their dreams".

Even eight years on, that pain is evident. "It's not just the families. It's the friends of these kids. This changes them," said Cameron.

"The Rotherham case brings it all back like it was yesterday."

The group refused to leave the grounds when told to do so, allegedly blocking prison staff from entering and leaving, and threatening police officers, the Metropolitan Police said.

The Met said several of them also managed to get inside a staff entrance area of a prison building.

It is understood the protesters did not get past security.

The group have been arrested on suspicion of aggravated trespass, the force said in an update on Sunday.

Footage shared on social media showed a group chanting outside the prison, with some holding signs.

At one point, the group can be seen moving towards a building - and one clip appears to show some demonstrators inside.

It is understood that they were holding the demonstration in support of Umer Khalid.

Mr Khalid is among five people accused of breaking into RAF Brize Norton last July and damaging two Voyager aircraft.

He denies the charges and has escalated his protest to a thirst strike.

A Ministry of Justice spokesperson said: "The escalation of the protest at HMP Wormwood Scrubs is completely unacceptable. While we support the right to peacefully protest, reports of trespassing and threats being made to staff and police officers are deeply concerning.

"At no point was prison security compromised, however where individuals' actions cause risk or actual harm to hardworking staff, this will not be taken lightly and those responsible can expect to face consequences.

"Prisoners are being managed in line with longstanding policy. This includes regular checks by medical professionals, heart monitoring and blood tests, and support to help them eat and drink again. If deemed appropriate by healthcare teams, prisoners will be taken to hospital."

He said Britons "were among the greatest of all warriors" as he acknowledged the 457 who died and many "badly injured".

"The GREAT and very BRAVE soldiers of the United Kingdom will always be with the United States of America!" Mr Trump wrote on Truth Social.

"It's a bond too strong to ever be broken," the president added.

"The U.K. Military, with tremendous Heart and Soul, is second to none (except for the U.S.A.!). We love you all, and always will!"

President Trump's post comes after he falsely claimed NATO troops in Afghanistan had "stayed a little back, a little off the frontlines".

Sir Keir Starmer had called the remarks "insulting and frankly appalling", while Prince Harry also defended the bravery of UK troops.

The prince - who served two tours of Afghanistan - said British "sacrifices deserve to be spoken about truthfully and with respect".

Downing Street said Sir Keir had spoken to Mr Trump shortly before the president's social media post on Saturday.

"The prime minister raised the brave and heroic British and American soldiers who fought side by side in Afghanistan, many of whom never returned home. We must never forget their sacrifice," said a statement.

Mr Trump made his original comments to Fox News at the World Economic Forum earlier this week, as he questioned if NATO would "be there if we ever needed them".

"We've never needed them," the US president said.

"They'll say they sent some troops to Afghanistan… and they did, they stayed a little back, a little off the frontlines."

Criticism from UK veterans, their families, and politicians was swift and severe.

Al Carns, the armed forces minister, who was with the Royal Marines in Afghanistan, called the claims "utterly ridiculous".

Tory MP Ben Obese-Jecty, who served there with the Royal Yorkshire Regiment, said it was "sad to see our nation's sacrifice, and that of our NATO partners, held so cheaply by the president of the United States".

Diane Dernie, whose son Ben Parkinson suffered horrific injuries in Afghanistan, called the comments "the ultimate insult" and urged the prime minister to stand up to Mr Trump.

The president's U-turn was welcomed by Conservative Party leader Kemi Badenoch.

"I'm pleased President Trump has now acknowledged the role of the British armed forces and those brave men and women who gave their lives fighting alongside the US and our allies," she wrote on X.

"It should never have been questioned in the first place."

Over 1,000 non-US NATO troops died in Afghanistan and at least double that number were seriously wounded.

At 457, the UK had the second-highest number of military deaths during the near 20-year campaign. The US suffered 2,461 deaths.

The American-led invasion came shortly after 9/11 as it invoked NATO's Article 5 clause that an attack against one member is an attack on all.

President Trump has been a frequent critic of NATO, saying the alliance is too reliant on US power and urging members to increase their defence spending.
