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.

I thought this was disappointing. It starts with a conclusion, then proceeds to push a narrative towards that conclusion, whilst ignoring evidence to the contrary. No attempt to unpick data, stats, ML, AI - all muddied together. This fails to be a credible critique

In Norway and noticed situational strategies for self-service checkouts I’ve not seen elsewhere. 1) a requirement to state you have scanned all items (set rules) 2) automated random checks on purchases by staff (formal surveillance) & 3) scanning receipt to activate exit barrier (screen exits)
