Changing the standard for judging police deadly force (🇺🇸) from “reasonable” to “necessary in defense of human life” had no effect on how many people were killed by police (as proponents claimed) or on how many officers were injured (as opponents claimed)

But, on the other hand, much more pleasant to walk or cycle through. Which is particularly important given how busy the area is with pedestrians.
“These figures are from the Crime Survey, so they aren’t affected by any changes in reporting to police.”
Liberating criminology from a narrow focus on offender motivation meant criminologists could also understand that crime is partly caused by opportunities, which has been hugely important in developing effective ways to prevent crime.

There were 680,000 personal thefts in 1995, compared to 344,000 last year. Criminal damage has dropped even more: 3.4 million incidents in 1995 to 656,000 last year.
(These figures are from the Crime Survey, so they aren’t affected by any changes in reporting to police.)
For example, in 1995 the likelihood of being a victim of violence at least once in a year was about 4.7%, compared to 1.3% now. The chances of being a victim of theft have fallen from 31.4% to 7.1% over the same period.
The Crime Survey does produce prevalence estimates (the likelihood of an average person being a victim of crime in any given year) and they show the same downward trend as in the charts Fraser posted.

Cops in the US discharge their firearms negligently hundreds (probably thousands, but there are no complete records) of times each year. British police firearms training is among the most rigorous in the world.

"The UK has fallen because two years ago someone who had probably never handled a gun before was photographed holding an empty gun the wrong way"
Is such a lame outrage chasing pile of tepid nonsense, you'd think the world had run out of things to be upset about.
This experiment finds a practitioner or global-south researcher without expensive institutional journal subscriptions can only access about 5% of criminology research.
Long past time more researchers (especially in the US) got serious about open access.

Useful short summary by @PizaEric of research evidence on the limited effect of CCTV (including automated numberplate recognition cameras) on crime and police outcomes.

Sure, and it would have been good if the paper had reported the proportion of drivers who were speeding before and after, as well as the change in average speed. But it’s notable that the average before the alerts was over the speed limit and the average afterwards was under.
So, as I said before, it looks like the main cause of vetting failures was rushing to recruit people to meet the Home Office target and avoid the loss of funding missing the target would lead to. Although as it turned out the Met missed the target in any case.
Sorry for the slow reply– I don’t check Twitter mentions often.
It looks like the vetting review unit you mention overturned 114 cases (not all non-white) out of 5,073 applicants who weren’t properly vetted during the push to meet uplift targets.

The decision not to install immobilisers on Kia/Hyundai cars (🇺🇸) led to over 1.1 million extra vehicle thefts over 5 years.
Note: unlike other developed countries, the US doesn't require manufacturers to fit cars with immobilisers.

Since apparently you only believe AI, try this:
ALT is the population of the administrative city of Paris a good basis on which to compare the overall population of Paris with the population of other global cities? No, using only the administrative city of Paris (Ville de Paris) is a poor basis for comparing its population with other global cities. Why Administrative Limits Fail • Fixed Borders: The official city limits of Paris (intra muros) have not changed for over 160 years (stretching across just 105 square kilometres), unlike cities like London or New York that absorbed surrounding suburbs. • Artificial Smallness: The administrative city houses only about 2.1 million people, making Paris look deceptively small. • Exclusion of Suburbs: It completely cuts off the continuous, built-up urban area that spills past the Périphérique (ring road).
