(1/7) New #OpenAccess article w/Claire Harkins & @hazen_K: “Do targeted, place-based educational campaigns influence citizen engagement and violent crime? A quasi-experiment of the alert conscience technique of situational crime prevention” in @CPPJournal: doi.org/10.1111/1745-9133.70…

Useful short summary by @PizaEric of research evidence on the limited effect of CCTV (including automated numberplate recognition cameras) on crime and police outcomes.
counciloncj.org/wp-content/u…
(6/7) Campaign exposure led to a statistically significant increase in 311 calls. In contrast, the campaign had no significant overall effect on violent crime or any of its subcategories.
(5/7) We tested the effect the campaign had on citizen engagement and on violent crime. We measured engagement through 311 calls for service, which prior research links to community custodianship and civic-mindedness.
(4/7) We evaluate a media-based violence prevention campaign. The campaign used 2 approaches: geofencing and clean graffiti. Geofencing delivered anti-gun-violence images to mobile devices. Clean graffiti power washed violence-prevention messages on sidewalks
(3/7) but that evidence draws mostly from “hard” techniques such as target hardening, access control, and surveillance. Much less is known about alert conscience, which seeks to awaken a potential offender’s moral conscience at the moment they are deciding whether to offend.
(2/7) A practitioner-focused research brief is available at bit.ly/scp-media. SCP aims to reduce crime by changing the immediate environment in ways that limit criminal opportunities. Evaluations generally show that SCP produces modest meaningful crime reductions
It's remarkable to me how little journals are paying attention to hallucinated citations.
Kudos to @CrimeDecoder for creating Versuscite. It's a true service to the profession.
So I typically review all of the hallucinated citations before I post them for the hallucination of the day, but this article has 50+, so I gave up after reviewing 10 of them.
I thought my tool had some error at first (and the DOI parsing was incorrect). But nope this is really just a bunch of wrong DOIs to hallucinated articles.
Thank you to @CouncilonCJ for having me write a brief on the Expansion of Police Surveillance Technology for their report "What's driving the Homicide Decline?"
The research brief is @: lnkd.in/eGPZMjp3

(1/3) The Journal of Experimental Criminology recently published a correction to our evaluation of GDT in Chicago: doi.org/10.1007/s11292-024-0…. A reader informed us of an error in our code that masked an increase in shots fired calls for service. Nate’s thread has more detail.
(2/3) Accounting for the corrected result, GDT led to increased gun recoveries and shots fired CFS & had no impact of shootings or general Part 1 gun crime in Chicago. Thanks to the reader (who declined the opportunity to be given credit for catching it) for reaching out to us.
This is crazy. I initially supported legalized sports betting but don't think there's enough guardrails. I recently checked the weather on my phone app and was greeted with an invitation to download a sports book app. There's no need for the amount of advertising we're seeing.
How many families are foregoing essentials to bet on sports?
*58 percent* of households making under $30K per year, and *38%* of those making $50-$99K.
New Capita report (capita.org/publication/quart…) dovetails with prior research showing that sports gambling legalization increases food insecurity (nber.org/papers/w35305).
Don't feel like doing a multi-part thread on here, so just sharing this screen shot. In short, it seems like we've gotten to a place where students aren't comfortable writing 100-word emails without having AI do it all for them! I don't know, this seems like a bad thing!
(1/6) My team and I have a new #OpenAccess article in Journal of Experimental Criminology "AI vs. Human Transcription: Evaluating Accuracy and Meaning in Police Body-Worn Camera Footage" doi.org/10.1007/s11292-026-0…
A practitioner-focused research brief is @ bit.ly/ai-bwc
(5/6) Accurately attributing text to specific people is key for lots of contemporary policing issues, such as procedural justice and de-escalation. For these topics, AI may miss important context.
(6/6) Thank you to the National Institute of Justice @OJPgov for funding this research. For all studies published from this project, see bit.ly/nij-avl-bwc
