On legitimising yet another pogrom.
Some prefer to step two degrees away from the above conclusion, blaming the violence not on one discrete crime, but rather on long-simmering discontent about “unfettered immigration”, to use the words offered by loyalist MP Jim Allister, in the wake of last year’s Ballymena riots. Such riots are appalling, the argument goes, but their anger reflects a legitimate concern; that immigration has simply gone too far.

Again, we risk demeaning ourselves by pointing out that rates of migration into Northern Ireland have never been connected to any rise in crime, and represent a tremendous benefit to the economy, from workers in hospitality and agri-business sectors to manufacturing and academia. Migrants are most beneficial in the health and care sectors, with 22 per cent of carers in the state coming from outside the UK and Ireland, without whom Tracey Reid, chief executive of the Northern Ireland Social Care Council, says the sector “could not survive”. Such statistics are, of course, broadly similar throughout the UK and Ireland, and were regarded as truisms until it became seemingly gauche for any prominent newspaper or politician to repeat them, in favour of contorting gymnastically to flatter the perceptions and prejudices of those who just hate migrants for entirely racist reasons. No matter how much they contribute to society, and no matter how few of them there are.

A compelling argument that this is the case can be found in the demographics of Northern Ireland itself. Its current population is just shy of two million. According to the most recent figures available, net migration in the state between 2001 and 2023 amounted to around 62,000 people, including less than 2,400 refugees in secure accommodation. Ballymena, which until this week had been the most prominent site of anti-immigrant violence in the state, sits in the Mid and East Antrim council area, which has seen fewer than 5,000 international migrants settle there this century. Only 3 per cent of Northern Ireland’s population belong to any ethnic minority at all.

For those of us who find the constant discussion of “the immigration problem” dehumanising and dishonest in any context, it’s revealing to see it deployed in places where immigration barely exists, not least for what it might suggest about such legitimate concerns everywhere else. We are left to presume that any number of non-white faces, no matter how few, is a salient enough horror for locals that their concerns become legitimised automatically. Even one, it would seem, is one too many.Most confusing of all has been the near-total absence of any context regarding who, exactly, is committing all this violence. The reluctance among media outlets to specify that these pogroms are the work of far-right loyalist gangs is particularly odd, given that such groups are fond of signing their work. The LVF, and associated gangs, have for decades sprayed their tags on the houses of the people they burn out, whether Catholics, economic migrants or refugees. Even now their graffiti proudly adorns walls and estates, demanding they be reserved for “locals only”. I’m old enough to remember when the LVF attacked the specially modified home of a severely disabled child because his family was insufficiently Protestant. I’m old enough to remember it because it happened less than two years ago.

When loyalist gangs burned Catholic families out of their homes in past years, there were few stern and sombre pleas that we should understand the arsonists’ concerns. Nor was there a reflexive jolt to place such acts in a context the perpetrators themselves might have liked, perhaps by drawing direct links between their violent acts and the existence of alleged crimes committed by disconnected Catholics many miles away. That this same logic is no longer applied to vast acts of violence against dozens of non-white people of all nationalities in Belfast, purportedly due to the actions of a single man from Sudan, is as preposterous as it is repulsive.

Night Nurse
Omar Sakr

I listen for the rustle and shuffle of their feet, Scrubbed and gloved, denied the dark and its stars, the night nurse is anything but, steward of the startling hallway bright, discordant dancer moving to the eerie orchestra of beeps, shrieks, and alarms. Every two hours they sweep in with careful hands to measure my son's blood pressure, to gauge the speed of his heart, put a number to the heat, the sacred fire that animates him but must be tempered; they check his fluids, administer drugs— ensure, in short, that he is well, and every two hours, I blink bleary at the blurred figure, who sometimes turns and smiles, whispering what might be a gospel truth or salutation, and vanishes again into the blinding beyond. Back home, miniature planets hang above our bed, a slow meander of cookie-cutter stars, and inside this shrinking universe, the quiet creeps in between us, a third body, deep as the void in space. I guess I must turn back now to the invisible watchers, or else hold to the memory of tender visitations.

You have to read this. Firsthand affidavit from one of the women who was there and recording the video. She talks about how Alex Pretti was directing traffic when she arrived. She watched him be killed in front of her. She's afraid to go home, worried she'll be arrested.
1. I am a resident of the Whittier neighborhood of Minneapolis, Minnesota. I am over 18 years of age. I am a children's entertainer who specializes in face painting.
2. On Saturday, January 24, 2026, at about 8:50 am, I was getting ready to go to work when I heard whistles outside. I knew the whistles meant that ICE agents were in the area, so I decided to check it out on my way to work. I've been involved in observing in my community because it is so important to document what ICE is doing to my neighbors. Connecting to your local community and knowing who your neighbors are is something I profoundly value.
3. I drove to Nicollet Ave. and 26th where I could hear the whistles coming from. I turned south onto Nicollet. There were already several ICE agents there and they'd set up a sort of vehicle convoy on Nicollet and 28th. There were also about 15 observers there, recording and observing ICE.
4. I saw ICE agents surrounding cars and punching car windows. I also saw them stopping vehicles further down Nicollet, so I backed up because I didn't feel safe continuing on.
5. I noticed a man sort of acting to help traffic move more smoothly. He helped me find a place to park. I got out with my whistle and my camera. I went over to him and said something like, "I'm going to film and use my whistle."
6. It seemed like most ICE activity was happening a little farther down the street from us, near 27th. Someone was being thrown to the ground.7. I started recording. There was an agent by a car across the street. Two observers were a few feet away from the agent, blowing their whistles. One was wearing a backpack.
8. I and the man who was observing and helping direct traffic were standing in the street. There was a phone in the man's hand recording a video.
9. An agent approached and asked us to back up, so I moved slowly back onto the sidewalk.
10. The man stayed in the street, filming as the other observers I mentioned earlier were being forced backward by another ICE agent threatening them with pepper spray. The man went closer to support them as they got threatened, just with his camera out. I didn't see him reach for or hold a gun.
11. Then the ICE agent shoved one of the other observers to the ground. Then he started pepper spraying all three of them directly in the face and all over. The man with the phone put his hands above his head and the agent sprayed him again and pushed him.
12. Then the man tried to help up the woman the ICE agent had shoved to the ground. The ICE agents just kept spraying. More agents came over and grabbed the man who was still trying to help the woman get up. All three of the observers looked to have been badly affected by the pepper spray. I could feel the pepper spray in my eyes.13. The agents pulled the man on the ground. I didn't see him touch any of them-he wasn't even turned toward them. It didn't look like he was trying to resist, just trying to help the woman up. I didn't see him with a gun. They threw him to the ground. Four or five agents had him on the ground and they just started shooting him. They shot him so many times.
14.1 don't know why they shot him. He was only helping. I was five feet from him and they just shot him.
15. The video I recorded of what happened accurately depicts the events leading up to the agents shooting him and several minutes afterwards. The video is attached as Exhibit 1.
16. I have read the statement from DHS about what happened and it is wrong. The man did not approach the agents with a gun. He approached them with a camera. He was just trying to help a woman get up and they took him to the ground.
17. I feel afraid. Only hours have passed since they shot a man right in front me and I don't feel like I can go home because I heard agents were looking for me. I don't know what the agents will do when they find me. I do know that they're not telling the truth about what happened. I've heard that other witnesses might have been arrested and taken to the Whipple Building.
18. I am disgusted and gutted at how they are treating my neighbors and my state. I keep alternating between crying and feeling determined it is important to remember the value of documenting injustice. We show up for the people who need us to bearwitness, because it can't just be one group of people bearing the brunt of their tyranny. This is a struggle to protect our freedom and democracy, those things are on the line. He lost his life for those values.
I declare under penalty of perjury that everything I have stated in this document is true and correct.

Dated and signed on Jan 24, 2026 in Hennepin County, State of Minnesota.

A thought, looking forward, at the strategy of the anti-Trump coalition, given the pattern we've seen, DHS will begin probably soon, drawing down forces in Minneapolis and going to harass some other place. It'll be useful to frame this as 'ICE defeated' and a 'retreat' - they are 'fleeing.'
