- “Jaywalking is permitted in London. In 1966, the police tried to crack down on it, but gave up after three months.” People walk and cycle on roads by right, people drive under licence. Jaywalking is not a thing in English law and Waymo must not change that. www.theguardian.com/commentisfre...

- Most of the pedestrian railings in London was removed after incidents of people on bikes being killed when crushed between railings and a lorry. On unexpected side-effect of removing the railings was that it made snatch theft easier, though.

- If you can spare 2 minutes for a survey on street lighting and perceptions of safety, I have a student who would be very grateful! 👍 qualtrics.ucl.ac.uk/jfe/form/SV_...
- Homicide is often made more likely by 'enhancers' such as drugs, alcohol, mental health or the involvement of street gangs. This thread summarises what we know about factors that make homicide more likely. 🧵

View full threadThis analysis of homicide enhancers in England and Wales comes from a report written by me and @iainbrennan.bsky.social for the UK College of Policing. You can get more detail at lesscrime.info/post/homicid... HT to @jerryratcliffe.net for the concept of crime enhancers.
- This is the last in a series of seven threads summarising different aspects of homicide in England and Wales. You can find links to the other threads at lesscrime.info/post/homicid... Tomorrow I'll post a thread with some concluding thoughts on what struck me most during this analysis.
- Gang-related homicide offenders were much more likely to be young: 90% of gang-related offenders were 29 or younger, compared to 51% of offenders in non-gang-related homicides. Gang-related homicide offenders were also more likely to be Black and less likely to be White.
- Gang-related homicides are often linked to on-going disputes, happen during feuds or brawls, or are committed in the course of the offender committing another crime.
- Black victims were also more likely to be killed in gang-related homicide: 36% of homicides of Black victims (and 11% of homicides of Asian victims) were gang-related, compared to 5% of homicides of White victims.
- Combining data on age, sex and ethnicity shows huge variation in the risk of being a victim of gang-related homicide: Black men aged 20–29 were 49 times more likely to be the victim of a gang-related homicide than White men of the same age.
