The images and stories coming out of Minneapolis are extraordinary. We can't say we did not know what was happening. Lots of people are putting their bodies on the line to make sure we do.

The actual story is that a family of American citizens trying to evacuate from a neighborhood that ICE had made unsafe, and then ICE tossed munitions into the car, causing three kids to be hospitalized and a six month old to stop breathing. DHS called the family “radical agitators”

There's someone in Ireland who doesn't understand that a "." in the e-mail does not make a unique e-mail address and I'm getting all their e-mail.
This is extra irksome because I actually understand much of the address portion of the e-mail RFC, yet can't inform this person 😅

Sometimes they just tell us they are weaponizing the criminal justice system to push their political agenda.
Sen. Kevin Cramer: "Maybe the point should be if you're the attorney for Jay Powell and you want to avoid an indictment, how about you go to Jeanine Pirro and say, 'I'll make a deal. I'll step down today if you drop the investigation today.' To me, that would be a win win for everybody."

MAGAs: The left is escalating the rhetoric by calling us Nazis
Also MAGAs: Look at our new podium, featuring a Nazi slogan about the time Nazis wiped out an entire village in Czechoslovakia and killed up to 5000 innocent people in retaliation for one Nazi being killed.
"One of ours, all of yours."

If you don't understand the whole Federal Reserve thing and why it's scaring the shit out of everyone, here's the very very abbreviated basics:
- The Fed sets US monetary policy independent of our government.
- That gives other countries confidence that when we put out numbers, they're real.

A murderer is a murderer. If the problem is that the state is sponsoring and defending a murderer and saying so aloud causes the state to sponsor and defend more murders, the source of this problem becomes utterly apparent.
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."

Don’t let the professionally dishonest & the intentionally disingenuous frame an issue as a binary choice of either getting run over or shooting a person. There is literally a universe of options between those two extremes. Stop listening to dolts or liars. Options, create them, and use them…

The people of Minnesota are sending their tax money to the federal government and in turn the federal government has cut them off from funding and sent armed goons to terrorize their cities. I'm not sure what else to call this

I really missed that dopamine hit of contributing to #OSS. Had a little time today and worked on adding Windows / PowerShell installer support to @captainsafia.com's great "grove" tool for git worktrees. Hope to get it over the finish line to enable more people to use it!

Very cool! I love the way that Julia approaches these challenges and solutions. If you're someone looking to contribute to a project, this is an absolute model of how to do it. And then she teaches us after! We're very lucky.
Looking forward to reading the data model doc in depth!

It is the position of the Trump Administration that its agents can come into any state and city in America (let alone other countries) and kill people and that state and city have no jurisdiction to inquire about it.
Treat any Trump official accordingly.

Um, you're not allowed to go door-to-door hoping to randomly find someone violating the law. You need a warrant. That's is basic Constitutional shit.
JD Vance: "It was a legitimate law enforcement operation. We were going door to door to try to find criminal illegal aliens and deport them from the United States ... say a prayer for that agent ... he deserves a debt of gratitude."

You and your wife drop your 6-year-old off at school. You just moved here. You see ICE terrorizing your new neighbors. You film them, as is your legal right. Your wife complies with orders. She is then shot in the head. You still have to pick up your child later today.
