My newest piece. A very personal one to write. It reflects lessons we're still collectively learning about how to see and respond to warning signs before something terrible happens. #TargetedViolencePrevention #ThreatAssessment #NVE #Prevention #YouthHarms www.hstoday.us/subject-matt...

This is one narrative we can do something about.

Curious about lettering on firearms used in extremist attacks? @arcglobal.bsky.social has you covered www.accresearch.org/accreports/t...

Phil always does a great job with hard topics, and I appreciate the opportunity to contribute to this story. Stay tuned for part 2 tomorrow night

Boosting this again because I posted during the server difficulties yesterday

The April 20, 1999 Columbine High School attack remains a critical reference point for understanding school shootings and their evolution, including connections to Nihilistic Violent Extremism (NVE).

"After being held in isolation for about five days. Rodríguez was forced to strip naked in a shower while an officer "poured some kind of chemical liquid on her head, which seemed to be something used to clean floors and burned her eyes,” the filing read."

As someone who studies online radicalization, this is 100% what parents must do, unfortunately, though it's not easy. Some of this content is obvious, some of it is substantially more subtle, especially in the early stages, yet radicalizes all the same.

Once upon a time, I worked for a place that helped Roblox with these issues. It is my understanding that they have since abandoned all such support, and not just externally.

I don't think I ever told her this, but one of the most valuable things I came across when working on my book was an almost in passing observation from @mirya.bsky.social talking about how there's research showing how motivation follows action.

I’ve spoken to a few journalists in the last week who have been thrown into reporting on nihilistic violent extremism (NVE). Even for people who have extensive experience covering other kinds of extremism, getting your head around this space can be a real challenge.

Today is my book's second birthday! It's relevant for understanding how militias both function think about themselves, including why many have a disjoint between their complacency about ICE alongside longstanding concerns about govt tyranny. share.google/g5peK0KVaZRM...

True. And also why @icde.bsky.social doesn't mimic the clout chasing approach of these entities in an effort to be the first to report after a tragedy. We want to make sure we have all the facts to best support our law enforcement and other stakeholders' needs for accurate, actionable information.

If anyone I'm connected to here is a historian of trans identity and experience and is willing to answer some specifc questions about non-US cultural experiences, I'd very much appreciate a DM!

One (very small) piece of added analysis about Bad Bunny's show: There was a niche but loud far-right fantasy that ICE would storm the field during halftime and make very public arrests of him and anyone else performing with him.

I came to Minneapolis to report on what's going on, and one of the main questions I showed up with is "just what is the scale of the resistance?" After all, we're all used to the news calling Portland a "war zone" or whatever when it's just some protests in one part of town.

"It's a surprise to people when I don't go at them. But I think if you want to learn about people, if you want to understand where they're coming from, you have to approach it with curiosity and you have to be willing to listen." - @noellecook.com

764 and other sadistic extortion networks are everywhere. Parents, school admin, and others *must* start learning the signals that kids are being exploited by these networks.

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...

If you haven't read @milleridriss.bsky.social's analysis of how misogyny undergirds so much of our present moment, this Fox op-ed on "deluded wine moms" being a threat to society can be your incentive!

According to my sources, the FBI was initially open to a concurrent investigation with the MN Bureau of Criminal Apprehension (the state agency that would do this investigation). Trumpy U.S. Attorney Daniel Rosen heard about this and intervened, barring the FBI from cooperating with local police.

Lots of folks are struggling right now. Phil has been fighting the good fight for a long time and would appreciate any help people can give.

I didn't watch, but my understanding is this is all I missed

Kids are awesome. One second they'll be talking about seeing a squirrel through the window. The next, they will deadpan, "Humans have so much blood in them."

I don't want to link to it, but the USA today article sanitizing 3 siblings who work for ICE along with their returned-from-retirement father is a lot. The family that raids together stays together, I guess, but the media continually carrying water for this admin in unforced capitulations is a lot

Had a blast talking (about terrible things with a shred of optimism!) today with @awkword.bsky.social

🚨Pam Bondi is ordering the FBI to “compile a list" of Americans who may be extremists, per signed memo leaked to me: www.kenklippenstein.com/p/leak-fbi-l...

So nice to have @noellecook.com's book out in the world! It's a helpful contribution to understanding white women's involvement not just in Jan 6th but also in radicalization more broadly. I was lucky to see this project as it was first coalescing, and I'm excited for other people to see it now, too

BIG: FBI spied on Signal group chat of immigration activists CourtWatch, classifying them as violent terrorist extremists for quietly sitting in on court cases, as revealed in intel bulletin we obtained & shared w/ @samtlevin.bsky.social @us.theguardian.com. #FOIA www.theguardian.com/us-news/2025...

Re-upping this today. If you don't know enough to adequately anticipate how bad actors are likely to misuse your work, you're probably not ready to be investigating those questions. If you do know and fail to adequately guard against it, you are not just complicit: you are a collaborator.

I specifically logged on to share this story, and as usual, @victorerikray.bsky.social already has it summed up perfectly (If you can't read the whole article, try archive, but all you really need is this headline)

I’m howling.

This is an excellent explainer, and my friend and @icde.bsky.social's executive director, @mattkriner.bsky.social contributed insights for it.

If you have to get permission to teach in your area of expertise from people who are definitionally not qualified to adjudicate your expertise then you are no longer working at a university. You’re working at a state propaganda factory.

Honestly, it reminds me of how profs I knew at both UM and Vandy would try to brag that they never watched TV (or in one case movies either). If you don't enjoy those things, fine, but if you're performatively opting out of cultural expressions to pretend moral superiority, whom does that serve?

Not to be too dark, but this has been something that's irked me about discussions of recent extremism: claims that it's happening purely because internet culture rots the brain. We know online technologies are bad for us in a variety of ways, but -

My newest work, with @regularpete.bsky.social and @mattkriner.bsky.social www.hstoday.us/subject-matt...

It's always nice when a physical book copy hits your hands, especially when your work is alongside so many great scholars' contributions. www.routledge.com/Contemporary... (Given the date, I was tempted to wear my vampire teeth, but that, uh, seemed like a mixed message)

One of the first things taught in (good) social science research methods courses is how to frame your data accurately. This isn't just about choosing and understanding the correct method for your data and question, though that is part of it. It's also about correctly presenting data to your readers.

This and the Chicago indictments make it abundantly clear that the rule of law is dead at DOJ. The agency has been fully weaponized to smite Trump’s enemies and shield his friends.

This is my top read for this entire fall- if you want to understand the data, the trend lines and their misuse, read this. 👇👇👇

@mikeajensen.bsky.social and I were perturbed at how a recent report on left wing terrorism and political violence is predictably being weaponized. So we dug into the analysis for @justsecurity.org www.justsecurity.org/122278/corre...
