MERKLEY: So when the VP said 'ICE agents have absolute immunity' in violating people's civil rights, he was effectively correct?

BIER: Effectively, yes. Right now as the law stands.

RON JOHNSON: 650k people that are at large in America have committed crimes. Mr Bier, you're shaking your head

BIER: They're not at large. They're in prison. They're in prison where they should be

JOHNSON: They're not detained!

BIER: They're detained by the states. They're not detained by ICE

KENNEDY: You said, 'Republicans think can troll their way to ethnic cleansing.' Did I read that correctly?

BIER: DHS tweeted for 100m deportations. That would be ethnic cleansing!

K: You don't think it's hyperbolic?

B: I think advocating 100m deportations is ethnic cleansing. Yes. Your time is up

At Largest ICE Detention Camp, Staff Bet on Detainee Suicides, AP Reports Camp East Montana has received several 911 calls in the span of five months about immigrants trying to harm themselves.

Staff at the nation’s largest Immigration and Customs Enforcement detention facility have placed bets on which detainee will be the next to die by suicide, according to new reporting from the Associated Press based on 911 calls and detainee accounts.

There is a legal provision in immigration law that someone married to a US citizen can stay in the US while there visa is pending. Immigration officials have long recognized it to allow residency during the wait time. The DHS has just stopped following this part of the law.

They've now killed four people -- three U.S. citizens and a Mexican national. They've shot several more.

They've lied about all of them. They haven't shaded the truth. They haven't "misled" us. They've brazenly, knowingly lied while in possession of the evidence disproving their lies.

CBS obtained video of the DHS killing of an unarmed man in Texas that DHS concealed for nearly a year, which clearly contradicts claims that he violently rammed anyone. He is shot with his brake lights on, car not moving or barely moving. Another DHS crime.

For anyone with relatives or friends who still claim Trump is targeting only "illegal" migrants, this interview with @davidjbier.bsky.social dispels the myth. It explains how the US govt is blocking legal immigration - even people who followed the process and paid all the fees to become citizens.

NEW: ICE tackled + arrested Juanita Avila, an Oregon shop owner who is a legal permanent resident and had her green card in her pocket.

When she asked through sobs why they didn't believe her, one masked agent replied: β€œBecause they lie all the time.”

NEW: Here's the story of a woman deported by Kristi Noem. Legally in the United States (as a DACA recipient), she is the mother of a U.S. citizen and was working to help the homelessβ€”but when she went for an appointment to get a green card, she was deported.

Good news that the execrable Kristi Noem has been fired, but Trump should really be firing Stephen Miller, the primary engineer of the vile ethnic reengineering agenda and murderously violent civic tensions that are sucking all of them into a bottomless political sinkhole, Trump included.

Columbia President with NEW details:

5 DHS agents entered a residency with no warrant.

They said they were police looking for a missing kid.
Security camera even captures them showing pictures of the "kid."

A campus officer asked for a warrant & their boss.

They ignored him & took the student.

Incredible opinion. It holds that the common ICE tactic of jumping out of an unidentified rental vehicle and seizing suspected noncitizens while masked violates the Fourth Amendment because the *manner* of the seizure is incompatible with a free society governed by the rule of law.

At this point, we should just assume they’re lying. But by their own account the kid had no record. US citizen. At the very least, it looks like multiple policy violations β€” they surrounded the car, fired into a moving vehicle, killed him through the driver’s side window.

The Supreme Court’s Declaration of Independence

Any Supreme Court in our nation’s history before John Roberts would have upheld the lower courts’ injunctions blocking Trump’s tariffs & not issued a stay that let Trump wreck the economy and break the law for over a year.

This gives you a sense of scale of the Trump admin's new refugee detention policy; they are claiming that all 100,000 of these lawfully present refugees MUST be arrested and detained for "re-vetting" and interrogation about their status.
