Not remotely legal. Minnesota needs to arrest these thugs breaking down doors right now, before they start grabbing even more power

Infuriating. Heartbreaking.
Somali-American schoolchildren have come home in tears, saying that classmates had called them “garbage.” Strangers with no evident connection to the government have walked into cafes and Somali-run businesses and demanded to see people’s papers.

This is disproportionately a DC Circuit issue: "Combined, Judges Gregory G. Katsas, Neomi Rao, and Justin R. Walker voted 75 times in favor of the administration — slightly more than half of the pro-Trump votes from Mr. Trump’s appointees logged by the Times analysis — and only three times against."

Homan: "We gotta stop the hateful rhetoric. Saying this officer is a murderer is dangerous. It's just ridiculous. It's gonna infuriate people more which means there's gonna be more incidents like this."

My newest paper explains why mergers do more harm to labor markets than previously assumed, and suggests four things antitrust agencies can do to reduce that harm if they aren't willing to ban the merger altogether.

It's all fun and games until the AI takes your job: I wrote about the wonder of building a website in Claude Code and the unsettling knowledge that it's coming for my job, too www.platformer.news/claude-code-...
Whether this feels like a good bargain or a bad one depends on where you sit. For the moment, Claude Code feels to me like a superpower. (What better way to fight the dying of the web, after all, than by building more websites?) But my enthusiasm is tempered by the knowledge that the technology that came for the Tailwind engineers is coming for me, too. Today Claude Code and its peers can make some incredible websites. Another year from now, I suspect they will be making much more.

When ICE said it was "going after the worst of the worst," we thought that was supposed to be their enforcement strategy, not their hiring philosophy

But Supremacy Clause Immunity is not absolute. It protects only law enforcement officials who act reasonably within the scope of their duties.

SCI requires that the officer be acting reasonably and within scope of the office. That's why I say, "if it attaches." As much as people want to predict how this shakes out legally, I just don't think we know how viable that defense is yet.

There is indeed terrorism here, as the government claims, but it is being carried out by the people with badges. Murder is a crime, and Minnesota should prosecute him

There is video of the shooting of a woman by ICE in Minneapolis circulating that shows an ICE agent repeatedly shooting her at point blank range while she tries to drive off. There was no obvious threat to any ICE agent.

Jump into my mouth!" -Shark Plato The first and best victoryis to conquer self. For the second best victory, it is all about survival, buddy! Whaddaya waitin' for? C'mon!

Plato is too woke to be taught in the philosophy department at Texas A&M under the new Texas academic censorship laws

Texas A&M decides that Plato is too woke (and too gay) to be read in College Station, because of risk that the Texas GOP would be offended.
