Yet another paper finds that decriminalizing drug possession in Washington and Oregon caused an increase in overdose deaths.

"Synthetic-control estimates show that both decriminalization regimes sharply reduced drug arrests and were followed by sustained increases in overdose mortality relative to matched counterfactuals. The estimates imply approximately 1,186 excess deaths in Oregon and 1,895 in Washington from 2021 through 2023. We also revisit the role of fentanyl supply shocks. A fentanyl-share control may partly capture enforcement-driven declines in non-fentanyl NFLIS reports, while alternative fentanyl measures leave positive overdose effects."

As a great new paper in Science demonstrates, the reason for this is probably not any particular American policy (in part because the same thing happened simultaneously in Canada), but a sudden and unexplained "drought" of fentanyl across North America.
* authors say China may be the explanation, but aren't particularly certain (in the paper and also in my conversation with one of them)
* they attribute the change to Biden admin negotiations, not Trump admin

I think the real third rail is that nobody wants to talk about whether and how much corporations should be allowed to take advantage of very stupid people.
the left doesn't want to admit they're stupid. The right doesn't want to admit it's taking advantage. So it's an impasse.
The problem with the guy who takes a payday loan to pay for his doordash isn't that he's poor, or oppressed, or whatever.

It's that he's not competent to have and use money in the 21st century.

Seems like a problem!

Begging, pleading with the right to stop doing crime-data trutherism. It's a bad look when the left does it, and it's a bad look when we do it!
1) NIBRS non-participation was an issue in 2021, when it may have downplayed the *growth* in the crime level. But, as @Crimealytics has argued, it's just not an issue anymore, both because the FBI is letting PDs report under SRS, and because UCR coverage grew.

2) Measured violent crime has *increased* in New York City. If you're going to claim they're faking the numbers, you should be a little familiar with the allegedly fake numbers!

Camping enforcement isn’t a solution to homelessness. It is a solution to public disorderliness and dangerous conditions.
Obviously the solution to people not having places to live is housing and/or shelter. But letting people take over public spaces until we resolve that problem is neither sensible nor humane as a solution.
This is exactly the same argument as “the solution to rising crime is to address the root causes.” Even if that were true, you need to do something in the meantime!
