Had the pleasure to present some of our research on the geography of fear at the Gothenburg book fair today.
It is a very large and fun event to visit.

Nu har Sebastian Näsström sitt ISP-seminarium, med David Sausdal från LU som granskare.
Sebastian forskar om vad vi kan lära oss om organiserad kriminalitet från fall kopplat till krypterade chattar samt om hur kokain-smuggling via europeiska hamnar kan förstås.

The fatality rate has continued to spike however.
12 month rolling average at 47% now. For 2025 it is at a staggering 56%, but that is partly driven by the deadly school shooting in February with 11 dead.
Excluding that results in more normal - but still very high - 45%.

Panel on county lines and exploitation of vulnerable in the UK. Interesting presentations, not least on cuckooing (taking over people’s homes) which I wasn’t aware of before!
Q/A had professors etc asking questions - but also three police officers commenting from their perspective.
Great mix!

Jens Widmark presents on an intervention to improve basement and attic storage spaces, through things like better doors and locks, lighting etc.
Using a 2way fixed effects DiD setup he finds that it resulted in 29 fewer thefts from attics and basements at 701 treated addresses

Dan Birks and colleagues have tested LLMs to assess the extent to which vulnerability (mental health, substances, homeles) can be identified in police reports. LLMs perform well, and with little bias for race/sex .

Shane Johnson reports preliminary findings from camera door bell RCT with London Met.
ITT results from first wave point towards 20% crime reduction on treated street segments.. But, significant with poisson, not with negbin, and second wave looking less promising

Interesting presentation by Vania Ceccato on the effect of changing lighting intensity and/or coloring on perceived safety in subway stations.
Using orange or blue color light appears to be a bad idea!

Spencer Chainey now demos a computational method to plan optimal police patrol routes, the method is much quicker to generate routes and covers more crimes than manual routing methods and to the London met hexagon method.
Very nice with a built dash board!

Very interesting study by @lisatompson.bsky.social on whether, how, and where, police bias manifests?
A very key finding - 87% - 447 - of the 523 studies on the topic are from the US! 27 studies from the UK - only 10 from the rest of Europe.
So US has 45 times more studies than continental Europe!

Cool study by @anttilatvala.bsky.social showing that ~random jobless during 90s recession had a stable _long term_ effect on crime.
Loosing your job in the 90s -> 20% higher risk for any crime next year &50% higher for property crime, but also 20% higher in 30 years, and the time in between

Our panel on the geography of fear at the Sthlm Criminology Symposium is now concluded. Very nice presentations by Karl (partial replication of Brunton-Smith & Sturgis), Nicklas (comparing two methods to measure unsafe places), Everett (RTM of unsafe places) & Lars (unsafe places for youth).

Now the Stockholm Criminology Symposium is starting with a discussion betweeen this year’s criminology prize winners - who are skeptical of prisons - and the Swedish minister of justice - who just launched a massive penal reform expected to lead to 16 000 more people in prison.

The group that is the most crime active is those that were recruited (minor committing crime with adult) who then become a recruiter (now an adult, committing crime with a minor).
This group averages 26 crime suspiciouns per person, making it a very interesting group to work with.

Amber Beckley and Kim Nilvall presents another method to identify recruiters, departing from co-offending of adults with minors.
They relate this to gang-databases, and find that higher ranked members of criminal networks are more likely to be recruiters, and non-gang offenders the least likely

Johan Kardell and Kim Nilvall has developed a quantitative method to identify potential recruiters into criminal networks and are pitching a specific deterrence intervention against them.
On a national level a lot of them, but in a local context most police districts have like 10-20
