London long-term homicide trends.

Comparison with NY. The UK media recently headlined that London was now safer than NY on this measure.

Data suggests that has always been the case.

OSINT: From Raw Text to Threat Assessment with Databricks In law enforcement intelligence, analysts are often required to produce intelligence assessments — drawing from human, technical, or…

I tested a Databricks workflow to turn raw OSINT into a strategic summary (Volumes + model endpoint).

Great for processing speed; accuracy, provenance, and bias remain uncertain - use with analyst oversight and clear evaluation criteria.

GitHub - routineactivity/hexseg: Spatial functions for analysing crime by hexagons and street segments Spatial functions for analysing crime by hexagons and street segments - routineactivity/hexseg

Not something I usually do, but excited to share a first attempt at creating a Python package, hexseg.

It assists in streamlining two popular count-based crime analysis methods by creating hexagonal grids or street-segment analyses across geographic study areas.

Spatial and Temporal Patterns of Risk: A Risk Terrain Modeling Approach in Stockholm, Sweden - European Journal on Criminal Policy and Research Decades of criminological research have highlighted the principle that “place matters” when analysing crime dynamics. While acknowledging this, our study emphasises that place matters at specific time...

New paper led by Mia Puur at Lund Uni out ✅
In the paper we show that combining spatial and temporal patterns is important to understand violent crime. Patterns differ a lot across weekdays vs weekends, mornings vs evenings etc.
