ICE agents in Chicago violently detain a non verbal autistic man for being “non compliant”
He couldn’t “comply” because of his disability…they don’t care
This is not the first time they’ve gone after a disabled person
They target the most vulnerable because it’s an easy way to meet their quota

In Chicago, a woman was driving to get coffee when a DHS vehicle fleeing an angry crowd crashed into her car. Armed agents jumped out of the vehicle, yanked her door open, pulled her by the legs out of her car at gunpoint, held her incommunicado for hours, then released her with no charges.

NEW: 12 Mississippi polling places have moved and 4 have been closed ahead of the Nov. 4 legislative special elections, an MFP investigation finds.
Counties also have incorrect addresses in the state system for 11 polling places, risking sending some voters to the wrong location.

Schools went on lockdown, people stayed inside. It lasted the entire afternoon. A constant din of whistles, sirens, helicopters, people shouting. Or dead silence.
I see the NYT, New Yorker, commentariat frame it as "activists clashing with ICE."
No.
ICE/CBP/DHS are terrorizing US citizens.

I love to see stuff like this because it helps explain to people trapped in tech-sponsored information bubbles the actually obvious fact that universities teach people to know & think things, and AI is a way to produce the effect of knowing & thinking things w/o actually knowing & thinking them.

When I worked in WaPo Opinions in 2017-2018, senior editors specifically told junior editors not to factcheck Marc Thiessen and other MAGA columnists, otherwise they wouldn’t be able to publish anything by them at all, and “we need them for intellectual diversity.”
It’s very telling that opening your publication to MAGA “thought” requires a massive downgrade in quality control.

I'm shaking almost too hard to type. I entered SLC airport and heard screams and cries for help. I could see people gathered around, watching. I sped over to discover this woman face down on the floor, four grown men pushing her down, while she cried "HELP ME" and pled for her child.

Johnson could swear Grijalva in today, but he won't, leaving this AZ district of 813K people with no member of Congress.
Why?
Because Grijalva will provide the final, 218th signature on a House petition to force a vote on the release of all of the Jeffrey Epstein files.

It's also pretty trivial to make the #emacs bibtex-mode linkify eprints (it already linkifies DOIs) so all you have to do is click or hit enter to open the arXiv or journal paper
