New blog post -- I think academics should self publish textbooks. Can set the price, format as you want, and update as you please. Using AI to help with those steps makes it even easier.

In a previous life, I worked in the London Metropolitan Police Strategic Insight Unit (SIU). We did lots of excellent research, and most never got released publicly... except I've just found lots of it was FOI'd! I've collected it all here, hope it's useful! andreasthinks.me/posts/siu-r…

OUT TODAY: The U.S. has seen a dramatic, unexpected shift in homicide. After surging in 2020, the rate fell sharply from 2022-2026 and is now at its lowest level since at least 1900. Why has homicide dropped so much, so fast, and in so many places? ⤵️ counciloncj.org/whats-drivin…

Violent crime is falling, but intimate partner violence isn't declining at the same rate. PERF's latest meeting calls for a comprehensive approach: intervene on every call, conduct predominant-aggressor & lethality assessments, engage victims, build partnerships & improve data.
Trending: Violent crime is falling. Intimate Partner Violence is not. What can be done? policeforum.org/trending3oct…

Check out my thoughts on why it’s good to publish preprints and reviews of them (and why that’s better than conventional journal publishing). Disagree? I recommend commenting on the post below 🧡

Another example of the synth app in action.
After Austin switched off its Flock license plate cameras in June 2025, car theft rose 24% when measured against trends in comparable cities. Austin's auto theft came in above expectations every month for the following year. About 776 more stolen cars than there otherwise would be.

My feed these days is mostly folks arguing about ALPRs and Flock cameras. In 2025, Omaha launched cityofomahaconnect.org/ I've been curious about it for awhile so I used @CrimeDecoder's new Crime Synth app to estimate monthly violent crime rates after rollout.

At this hearing, the Department's lawyer claimed that the department didn't benchmark against other cities or look to see what they were up to, because it's "singular." @CrimeDecoder provides a a great benchmarking tool that let's you do it! apwheele.github.io/CrimeDeco…
At yesterday’s Public Safety hearing, I started by giving the men and women of the @NYPDnews credit for the significant reductions in shootings and murders. Our police officers deserve it. But there are still serious questions that need answers.

Part of the difficulty in writing a book on LLM APIs is that they change so often. LLMs for Mortals is 6 months out, and I wrote a recap of updates needed so the book recompiles (mostly just newer model strings). But a few things probably by next year will need to be changed in the book. AWS uses a token now, should update with some of the newer open source models (and show calling from Databricks or Baseten US endpoints). And may need to take out sections on temperature and logprobs. See blog post for promo code for EPUB and print versions of the book.

Quick blog post based on some the recent @cremieuxrecueil posts on the prevalence of hallucinated citations (which are often around 1% of citations in recent preprint servers). I think these are likely underestimates, as those papers only check titles. I did a quick coding for some of the recent papers in my hall of hallucinations, and close to half would not have been caught just looking at the titles. Totally wrong authors are the most common example. So it might be twice as bad as people are estimating!

Newest blog post (I am lazy and just had AI write it from my notes full disclosure). If criminologists do not disclose data and code for synthetic control designs, they can easily fake the model fit to provide whatever results you want. Here are three fake results for Gascon's tenure in LA as a prosecutor on thefts.

Can a fruit fly brain read criminology? Mostly no. Why? Criminologists aren't making their articles open access. See for yourself at fruitfly.crimconsortium.com

In another one of this fellow's paper, he cites an article about pets and Hurricane Katrina. The rub is the article does not exist, and even if it did, was published in 2001.
Hallucination of the day comes from researchers at Microsoft. My tool classifies hallucinations as information that directly conflicts with the known ground truth. So made up authors or titles or periodicals that are wrong are flagged. If you just make up papers entirely though, it will say not found. So this has 14 flagged hallucinations, the other 4 not found though likely are hallucinations as well.

After 35 years of too many incidents to count, I wrote this from a deep commitment to criminal justice as an academic discipline—especially academic–practitioner work. I hope it reaches beyond CJ. For practitioner colleagues: these partnerships connect theory to practice and enrich the discipline. The stories I could tell. Article PDF: jbhelfgott.com/.../Helfgott-…...

An obscure academic just put out a new working paper on American gun ownership that will shape the gun debate, including an imminent Supreme Court case on whether states can ban assault weapons. It deserves more scrutiny than it's going to get. Some thoughts. 🧵
