Interviewed by Canadian Affairs on youth radicalization online in Canada. The piece highlights how benign content can act as entry points into extremist ecosystems, a dynamic central to our European Union funded project "AMALTHEA". www.canadianaffairs.news/2026/03/25/d...

A new piece in @thewalrus.ca looks at the nexus of the Canadian military and far-right extremism. I contributed context on how we study this issue in Canada, where data gaps mean relying on media reporting, ATIPs, and comparisons with other militaries. Worth a read: thewalrus.ca/in-quebec-ci...

If confirmed, the reported arrest of “Zé Carioca,” the alleged designer behind the Urutau, would be a significant development. Last year, we examined the Urutau and its implications for the global 3D printed firearm ecosystem for @gnetresearch.bsky.social gnet-research.org/2025/01/08/b...

Honoured to have my paper, “Ghost Guns, Real Violence: The Strategic Use of 3D Printed Firearms in Far Right Terrorist Plots,” featured in this inaugural issue. The article examines how 3DPFs are becoming embedded in extremist attack planning, often alongside explosives and other weapons.

Important investigation by the @antihate.ca. I was asked to comment on the case and noted that the presence of right-wing extremist ideology within military institutions can produce multiple forms of harm, from reputational damage to risks for personnel serving within the chain of command.

13 year old me would be so jealous of old me.

Quoted in ABC News on 3D-printed firearms after the Bondi attack. Software blocks on 3D printers may raise the barrier to entry, but they are not a panacea. Technical fixes alone will not keep pace. www.abc.net.au/news/2026-01...

It’s easy to imagine agents of state violence — like ICE — as uniquely evil. But history shows, under the right conditions, most humans are capable of horrors. It’s only in confronting that reality that we can begin to inoculate ourselves against it. @yveilleuxlepage.bsky.social helps explain:

Today I will be joining @rachelgilmore.bsky.social on Bubble Pop to discuss how ordinary individuals become agents of state violence, how language and institutions shape that process, and why it matters right now. Tune in at 11 AM EST.

🧵“How do seemingly ordinary people become agents of state murder?” This is one of the guiding questions I ask students in my graduate class on genocide/state violence. With recent events, it is a question many Americans are asking. I do not have a definitive answer, but here is a reading list: 1/

At the risk of repeating myself... "death squad behaviour".

On the killing of Renee Nicole Good, I just published a piece in @foreignpolicy.com arguing the Trump administration is weaponizing the narrative of “vehicular terrorism” as a shortcut to justify an unlawful killing: “death squad logic, adapted to American streets” foreignpolicy.com/2026/01/13/v...

✅ @yveilleuxlepage.bsky.social has been verified by @bsky.app.

🧵In my expert opinion as a researcher of vehicle ramming attacks, what has been publicly described in the video evidence does not support the claim that Renee Nicole Good was attempting a deliberate ramming attack when she was shot in Minneapolis on January 7, 2026. 1/7

One of the things that interests me most about this topic is how extremist violence reflects a broader armament culture where weapons are not just tools but carriers of meaning. When firearms are inscribed, customised, or 3D-printed with symbols, they become artefacts of identity and belonging.

Darren Steele, 29, from Newton Mearns, was arrested in 2023 after police found explosives, Nazi memorabilia, and 3DPF files. Newly released details show he had searched for Nicola Sturgeon’s home, suggesting a potential plot against the former First Minister. uk.news.yahoo.com/man-far-mate...

A 29-year-old man in London has been convicted of terrorism and firearms offences after attempting to 3D-print an FCG-9 Mk2 gun. Another case underscoring how extremists are adapting emerging tech to bypass controls and build capability. news.met.police.uk/news/man-att...

Deeply honoured to have presented my research at Everytown’s summit in NYC on the evolving threat of 3D-printed firearms. I discussed findings from my dataset of 50+ cases involving extremist actors, highlighting patterns, operational trends, and indicators. abcnews.go.com/US/wireStory...

I spoke with Le Journal de Montréal about organized crime within the CAF. Cases at CFB Valcartier highlight the need for better data, transparency, and vigilance against infiltration that threatens both security and institutional integrity. www.journaldemontreal.com/2025/10/10/d...

Belgian authorities recently uncovered a suspected terrorist plot involving plans to use a drone to deploy an explosive device, alongside a 3D printer allegedly used to produce bomb components. www.politico.eu/article/belg...

In the wake of Charlie Kirk’s assassination, and reports that the suspect etched obscure internet memes onto recovered bullet casings, @yveilleuxlepage.bsky.social examines the rise of inscribed and decorated firearms in political violence and argues such markings are deliberate communicative acts.

Reddit has finally banned FOSSCAD, the largest and longest-running subreddit dedicated to 3D-printed firearms. The community was removed for violating Rule 7: "Keep it legal, and avoid posting illegal content or soliciting or facilitating illegal or prohibited transactions."

At a Canadian charity festival, scammers used a 3D printer to make fake $8 tokens, defrauding local groups. Beyond weapons, 3D printing has enabled fraud from license plates to fake IDs. Emerging tech isn’t dangerous itself, but misuse is unpredictable. globalnews.ca/news/1141560...

The killing of Charlie Kirk echoes the assassination of Jean-Paul Marat. Both were polarizing figures, admired by supporters and reviled by opponents. History shows assassinations rarely silence. They create martyrs, amplify conflict, and shape politics long after the act itself.

New article with Joery Matthys in Het Tijdschrift Politie. Using Operation Desarme 3D as a case study, we explore how right wing extremists across Western countries are experimenting with 3D printed firearms and what this means for law enforcement internationally.

Australia’s strict gun laws are being eroded by 3D-printed firearms. As I note in @australia.theguardian.com, 3DPF designers frame their work as a “new Second Amendment." Cultural artefacts meant to undermine state authority. www.theguardian.com/australia-ne...

Five CAF members suspended after a video showed Nazi salutes. Comes as RCMP charge Quebec soldiers in a terror plot with Canada’s largest-ever weapons cache. As my 2022 ICCT paper warned, extremism in the ranks erodes trust and worsens the CAF’s recruitment crisis. globalnews.ca/news/1134155...

A Nova Scotia veteran with PTSD, Daniel Desmond Crowder, has become the first Canadian manufacturing 3D-printed firearms to receive a Terrorism Peace Bond. This marks the 3rd Canadian case linking 3DPF and extremism. www.thecanadianpressnews.ca/atlantic/p-e...

After nearly 2 years of legal proceedings, UK teen Ondrej Sidelka has been sentenced to 2 years in custody for terrorism offences. He maintained a digital archive of neo-Nazi propaganda, EID guides, and 3D-printed gun files intended to aid terrorist violence. uk.news.yahoo.com/chilling-dis...

I joined The Big Story podcast to discuss the recent RCMP operation that shut down an alleged militia in Quebec involving current and former CAF members. 🎧 Listen here: podcasts.apple.com/ca/podcast/r...

Spoke with Le Devoir alongside Evan Balgord on the arrests of 4 men in Quebec, including 2 Canadian Armed Forces members, linked to far-right extremism. We discussed militias, radicalization in the military, and online propaganda. www.ledevoir.com/societe/8991...

Yesterday, I spoke with La Presse about four Quebec men accused of trying to form an anti-government militia. We discussed how far-right extremists are co-opting Russian military imagery and reframing the Russia-Ukraine war through ideological lenses. www.lapresse.ca/actualites/2...

Spoke to La Presse about extremism in the military. Most serve with integrity, but a small number can pose real risks. Canada could learn from Germany’s transparent approach to tracking radicalization. www.lapresse.ca/actualites/j...

Two recent cases expose the ongoing threat of extremism in the Canadian Armed Forces: a private FB group sharing hate content, and a militia plot involving active-duty soldiers. Most CAF members serve with honour, but these are serious issues. I co-wrote a study on the risks icct.nl/sites/defaul...

IDF reports another two weapons smuggling attempts via drone on the Egyptian border, including one UAV carrying 10 firearms. I explored this exact trend earlier this year in a @gnetresearch.bsky.social Insight: 🔗 gnet-research.org/2025/06/05/g...
