Thanks for getting back to me Asier. That’s not it (it’s a recent pub in last few weeks) but this helps too. Cheers!

Crime nerds, I need help. @LessCrime's excellent RSS feed recently posted an article about what I think was a study looking at if people took more cyber crime prevention advice when it was from authorities rather than hackers (if I recall), but now I can't find it. Anyone help?

This week is the ASC conference, so here’s mentions of “abolish” in recent programs:
2021 1 program, 5 submissions
2022 1 submission
2023 4 programs, 5 subs
2024 5 programs, 3 subs
2025 2 programs (not incl. one about abolishing nuclear weapons)
Is this idea's rampant stupidity finally receding?

An interesting thought experiment here, and ... if you follow the logic of the thread, raises broader and potentially significant questions about the validity of 'lived experience' as a viable criminological research tool.
I've been wondering recently how many racist police officers were racist when they joined, and whether part of the issue is logical fallacies arising from having a lot of contact with very narrow sections of society in places with which they may not otherwise be familiar.

No, but we can examine other questions alongside the political circumstances. It's not like those other questions are not (rightly) being asked... just about everywhere.

National Guard presence may deter crime, but experts warn of the long-term costs
As President Trump ramps up efforts to send federal officers and troops into cities, criminologists are watching closely. Are the feds doing this in a smart way?

I agree with the tenor and points of ALL of the interviewees in the article, and reiterated many of the arguments and concerns mentioned by others. But there’s no point in the reporter using the same quote from everyone. I’m sure they are all equally aware of the UK research and it is relevant.

To contextualize this week’s political commentary, of the 2,647 identified extremist violent offenders in the US since 2000, far-right extremists were more than 7 times more represented in the data than far-left extremists.

Absolutely... they all have long term relationships: David Weisburd, Geoff Alpert, Larry Sherman, Anthony Braga, Wes Skogan, Cynthia Lum, and many more. And they are all practical about the work they do. Helping the departments work on their needs, not just research interests.
