One thing that didn't make it into today's piece:

Washington, DC already has by far the highest number of law enforcement officers per capita of any city of 250k+.

America has lost 116k manufacturing jobs over the last year—that's the fastest pace of job loss since the early COVID era and worse than any period from 2011-2019.

Big drops in the transportation (-49k) & electronics (-32k) industries drive most of the decline

Reporter: The FDA has a new AI tool that's intended to speed up drug approvals. But several FDA employees say the new AI helper is making up studies that do not exist. One FDA employee telling us, 'Anything that you don't have time to double check is unreliable. It hallucinates confidently'

There are a lot of reasons this is good, but also a counter to the democracy is over talk. This was not pretty and there are real worries for the future with how it went, but the winner of the election gets her seat. And that wouldn't be happening if people just resigned themselves to The End.

There is growing evidence that crime is plunging incredibly fast across a wide swath of the country so far in 2025. There's still time for these trends to change, but the first 3+ months of 2025 have likely brought an enormous decline in crime. New this week: jasher.substack.com/p/crime-is-l...

Not sure about other cities but Charlotte is clearly an outlier with a ~20% increase since 2023 (from Jeff's data and the end-of-year report by CMPD). Partially due to the large growth the city has seen. If you get the per capita rates then it is a 0% change.

Today HUD released data showing homelessness has reached a record high in 2024, jumping roughly 120k compared to last year

The jump was especially pronounced in New York, which saw a 55k increase compared to last year, and Illinois, which saw a 14k increase.

NEW: Why do we always think crime is rising, even when it isn’t?

This week I looked at one of the big data mysteries. Britain is 2/3 less violent than the 1990s; thefts were higher pre-lockdown

Why, then, doesn’t it feel like it?

⚠️ Perhaps stating the obvious, but you cannot trust ChatGPT to summarise the law on a particular topic. The way they are built involves no checking whatsoever of whether what they say is right or wrong.
There is lots of debate about the risks and benefits that AI will bring to policing and criminal justice. One danger I've recently discovered is police officers using online AI tools to interpret or apply the law for them. Needless to say, the AI often gets the law wrong.
