One of the benefits of good intelligence/crime analysis is that it can stop police wasting scarce resources on wild goose chases. This analysis of a supposed serial killer (🇺🇸) is a good example (the victims almost certainly drowned accidentally): digital.library.txst.edu/items/86182f1f…
Police officers (🇺🇸) generally accepted their agency using an AI tool to give them automated feedback on their behaviour during interactions with the public, and became less concerned (but not positive) after they’d used the system for a few months. doi.org/10.1007/s12103…
Very useful systematic review by my @UCLCrimeScience colleagues of all the crimes that can be facilitated by internet-of-things devices. Just in case you were in need of some nightmare food. discovery.ucl.ac.uk/id/eprint/1021…
Body-worn video (🇨🇦) didn't affect officer discretion in issuing traffic tickets, but did lead to ticket cases being dealt with faster and made guilty verdicts more likely. doi.org/10.1007/s11292…
A masterclass by @ian_t_adams in how to test a theory, using the example of 'ghost criminology' (a reasonable idea hiding behind a silly name and a huge amount of waffle). The end result being the theory isn't supported by experimental evidence. doi.org/10.21428/cb6ab…
Useful review of 50 studies into how online romance scams operate and which steps in the process should be the focus of prevention. It particularly highlights the high risk of repeat victimisation, which is especially important for targeted prevention. doi.org/10.1177/152483…
It’s great to be spending the evening seeing this year’s cohort of BSc Crime and Security Science students graduate at the Royal Festival Hall.  it’s always so nice to be able to congratulate them individually afterwards, and to meet their proud families. 🎓👏
Today I spoke at #EuroCrim2025 about how to forecast the frequency of crime to support strategic decision making in policing. Slides: lesscrime.info/slides/esc-202… Working paper: doi.org/p4vn Please get in touch if you’d like more information!
We are very pleased that our joint evaluation of video first response (VFR) to non-emergency domestic abuse calls with @CollegeofPolice has been published. college.police.uk/guidance/viole…
This new paper outlines a process police leaders can use to methodically consider the issues associated with introducing algorithmic decision making (e.g. using AI) in different areas of policing. doi.org/10.1177/003225…
Far too much of our knowledge of what works to prevent crime comes from a few countries (mainly 🇺🇸🇬🇧, a bit of 🇨🇦🇳🇿🇳🇿), so it’s good to see this evaluation of challenges faced by a domestic-abuse prevention programme in the Dominican Republic: doi.org/10.1080/019240…
A useful guide for researchers on how to approach research collaborations with agencies such as police. Almost all the top researchers in our field are notably good at applying the tips listed here, especially the need to build long-term relationships. doi.org/10.1080/247519…
A wrap-around tailored support scheme (🇨🇦) for gang members was associated with fewer subsequent arrests. Note, though, that there was no comparison group (so I do wonder if the causal language in the paper is fully justified). crimrxiv.com/pub/590asa78
Visual clues (shrubs in front of a house, box for a new TV left out, etc.) influenced which houses burglars (🇺🇸) exploring a virtual-reality neighbourhood targeted. Useful reminder that occupants choices’ help make their property safe/unsafe from crime. doi.org/10.1111/1745-9…
New study finds pretty close alignment between the circumstances in which the public (🇺🇸) thinks police should terminate a vehicle pursuit and when police typically *do* terminate pursuits (higher speeds, busy traffic, bad weather, minor crime, etc.) crimrxiv.com/pub/ukiumeyg
