DHS has arrested two medical personnel at a surgical center in California for demanding that the officers trespassing in their building identify themselves & provide a warrant, accusing them of another.... wait for it... ASSAULT. The case shows how DHS lies relentlessly to violate the Constitution

With Tom Lehrer's passing, I suppose this is a moment to share the story of the prank he played on the National Security Agency, and how it went undiscovered for nearly 60 years.

They aren't against illegal immigration. They want immigration to be illegal.

Trump’s immigration machine is abducting Oregonians without causeβ€”including four U.S. citizen children in my districtβ€”and detaining them in a windowless cell with NO access to counsel.

This is not law enforcement. It’s authoritarianism.

apart from its inherent qualities as a comic strip, I really appreciate that Watterson resisted the urge to franchise and merchandise C&H. There's no animated movie, no tv show, no line of toys, no ipad game.

it exists in its entirety as a comic strip written and drawn entirely by one man.

This is a great and moving story.

Last 4th of July in Seattle I came across a huge naturalization ceremonyβ€”hundreds of people from all over the world officially becoming Americans. More of this!

"Alligator Alcatraz" is wrong and media should not use it. It's propaganda. Alcatraz held people convicted of crimes, particularly violent crimes.

The Florida camp holds people *not* convicted of any crime. If they had been, they'd be in prison elsewhere.

The site is a textbook concentration camp.

And remember, 93% have no record of any violent crimes. This facility, then, is comparable to the internment camps for Japanese Americans during the Second World War. But let's call it what it is: a concentration camp. Jesus wept.

This is remarkable. New Quinnipiac poll finds support for path to legalization for most undocumented immigrants has risen to 64%. Only 31% want most of them deported.

That's a 14 point net swing for legalization since Trump took office.

On immigration generally, he's at 41-57!

For the first time ever, ICE is holding nearly 12,000 people who have no criminal convictions or criminal charges in squalid overcrowded deportation centers.

The best Easter egg: there’s an Asiacrypt β€˜91 poster on the office door of the missing scientist, purportedly snuck in there by Len Adleman (who was the science advisor to the movie).

In the past week, a union leader has been arrested, a U.S. Rep charged with a crime, a U.S. Senator violently handcuffed, and reporters shot with rubber bullets and detained. There is no ambiguity. This is a regime operating as an authoritarian. Americans who believe in liberty must oppose it.

AFAIK the Wagner-style attacks are still SOTA. There are some quantum versions of these that yield some improvements over classical. I once wrote a script to automate/optimize these kinds of estimates and could hopefully dig it up.

Just throw it onto the pile of reasons (as detailed by @radleybalko.bsky.social) that Sen. Bill Cassidy should be shamed for the rest of his life for for his craven, tie-breaking vote in support of RFK Jr.

Health secretary RFK Jr. abruptly fires CDC vaccine advisory panel Health secretary Robert F. Kennedy Jr. has taken the extraordinary step of firing the expert panel that advises the CDC.

BREAKING: RFK Jr. fires ACIP, the panel responsible for advising on vaccines.

This breaks a promise to Sen. Bill Cassidy, who voted to advance Kennedy as HHS secretary on the condition that he would, among other things, keep ACIP in place.

Abducting people at work sites - meaning they have jobs.
Capturing them at court dates - meaning they're following the law.
Blocking them from accessible higher education - meaning they're striving for more.
And peddling lies about jobless, lawless, driftless.

ICE Arrests Mississippi Father at His Citizenship Hearing ICE arrested Kasper Eriksen, a Mississippi father, at his citizenship hearing, imprisoning him and threatening him with deportation.

Kasper has never been charged with or convicted of any crime, nor accused of being a member of MS-13 or Tren de Aragua. What led the government to rip Kasper out of the arms of his family was, to the best of his knowledge, a single document: Form I-751.

Here’s our 1st profile. Widmer Josneyder Agelviz Sanguino entered the United States legally as a refugee. He was extensively vetted abroad including in-person before coming to the US, but was still detained and renditioned. This is criminal behavior by the USG.

Cato has published my comprehensive review of the ~240 Venezuelans the US government renditioned 2 months ago to Salvador’s notorious prison. We identified FIFTY who came legally, never violated any immigration law, but are imprisoned at the US government’s request and at US taxpayer expense.
