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, digesting 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 President 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 Greater Manchester mayor said on X: "I have today written to the Chair of Labour's National Executive Committee seeking permission to enter the selection process for a candidate for the forthcoming Gorton and Denton by-election."

It comes after former minister Andrew Gwynne formally stepped down on Friday on health grounds.

As a directly-elected mayor, Mr Burnham needs to get approval from Labour's ruling national executive committee (NEC) before entering the race to be the party's candidate.

In his letter to the NEC, which he shared on social media, Mr Burnham said the decision had been "difficult" but insisted he would support the work of the government "not undermine it" and that he had "passed on this assurance to the Prime Minister".

Mr Burnham claimed there was now "a direct threat to everything Greater Manchester has always been about from a brand of politics which seeks to pit people against each other".

He added: "I see this by-election as the front line of that fight for the Manchester way and I feel I owe it to a city which has given me so much to lead it from the front, despite the risks involved."

If elected, Mr Burnham would be required by law to stand down as mayor of Greater Manchester, which would then trigger a by-election for that role.

If he became an MP, he could mount a leadership challenge against Sir Keir Starmer.

However, the NEC can still block his bid for selection by refusing permission, and supporters of Sir Keir are reported to be mobilising to prevent him from becoming a candidate.

But several senior Labour figures have called for Mr Burnham to be allowed to stand, with the party's deputy leader, Lucy Powell, saying the decision should be up to local party members.

London mayor Sir Sadiq Khan said: "I think if Andy Burnham wants to be a member of Parliament, Andy Burnham should be allowed to be a member of Parliament."

Ed Miliband, the energy secretary, said Mr Burnham would be "a massive asset" in parliament, and hoped the Gorton and Denton party members would have "the option" of selecting him as a candidate.

The timetable for the Gorton and Denton by-election is short.

The deadline for applicants to put their name forward is midnight on Sunday, with a longlist of candidates set to be drawn up by a selection panel on Monday.

Shortlisting interviews will be held on Tuesday before hustings and selection will take place next Saturday.

Mr Burnham lost two previous Labour leadership challenges - against Mr Miliband in 2010 and Jeremy Corbyn in 2015.

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 National Police Service (NPS) will be established in England and Wales to tackle crimes such as terrorism, fraud and organised crime that are not constrained by areas, the home secretary will announce on Sunday.

Shabana Mahmood will say the NPS will attract "world-class talent" and use "state-of-the-art" technology - although a start date has not been revealed.

The NPS will be in charge of purchasing new tech and equipment for all forces - and will include a nationwide roll-out of facial recognition tech, which has seen London's Metropolitan Police arrest more than 1,700 suspects in two years.

It will also bring the National Crime Agency, counter-terrorism policing, regional organised crime units, police helicopters and national road policing under a single organisation.

Currently, different forces are responsible for those sections of national policing.

A national police commissioner will be appointed to lead the NPS, making them the most senior police officer in the country.

The home secretary said: "The current policing model was built for a different century.

"Some local forces lack the skills or resources they need to fight complex modern crime such as fraud, online child abuse or organised criminal gangs.

"We will create a new National Police Service - dubbed 'the British FBI' - deploying world-class talent and state-of-the-art technology to track down and catch dangerous criminals.

"In doing so, local forces will be able to spend more time fighting crime in their communities."

One of the main aims is to boost the 43 local forces' ability to spend more time fighting crime in their communities, such as shoplifting, drug dealing, phone theft and anti-social behaviour.

The Home Office said the NPS will make sure the public receives the same service from the police, no matter where they live.

The new force will also set professional standards and training requirements for policing, so every officer in the country is subject to the same standards.

In a bid to be more accountable to the public, local forces will have new targets on 999 response times, victim satisfaction, public trust and confidence.

They will be published, and forces will be graded for comparison.

As policing in Scotland and Northern Ireland is devolved, the NPS will only cover England and Wales.

The announcement comes ahead of Ms Mahmood announcing plans which the government has said will be the largest reforms to policing since the police service was founded 200 years ago.

She is expected to outline reforms that mean local forces protect their community, and national policing protects everyone.
