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.

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.

A Fatal ICE Shooting Occurred in Texas Months Before Renee Goodโ€™s Killing

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

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.

Courts have ruled 4,400 times that ICE jailed people illegally. It hasnโ€™t stopped. The decisions amount to a huge legal rebuke, one the administration has ignored.

This is a truly horrifying memo. It says that the policy of the US government will now be to proactively seek out and arrest likely tens of thousands of refugees who entered legally under Biden and subject them to detention, where they will be interrogated about their status.

Third American death linked to ice uncovered by Newsweek While the 23-year-old's death was reported in March 2025, it was not made clear that a federal agent fired the fatal shot.

DHS successfullyโ€”until nowโ€”covered up the murder of a third US citizen on Texas' Padre Island, the sort of thing that can only happen in GOP-ruled Texas. ICE agents shot and killed Ruben Ray Martinez, 23, last year, but DHS covered up the whole incident, Newsweek reports.

The horror stories rolling in from Minnesota are just the tip of the iceberg. This 20-year-old, who's lawfully present in the country, was arrested for being Latino, then jailed in a filthy cell where he couldn't even sit down. 18 days of illegal detention. democracyforward.org/wp-content/u...

A very detailed explanation of how FBI bamboozled a magistrate into authorizing a raid on Fulton Countyโ€™s election offices by omitting critical information that would have totally undermined any probable cause claim. Pretty clear-cut case of calculated deception of the courts.

The Constitution is not a bargaining chip for a budget negotiation The Democrats demanded that Trump's immigration cops follow the law and the Constitution. The Republicans called those demands "nonstarters."

New at The Watch:

The Democrats' demands to "reform" Trump's immigration thugs aren't reforms at all. They're already the law, the Constitution, and widely accepted police practices. And in a free society, they'd never be negotiable.

- Sanchez did not explain and Alford ignored that this was a change secretly implemented by DHS in this administration.

I mean, that would be fine if it were true. Obeying the Constitution makes it unfeasible to do certain things, and thatโ€™s fineโ€”indeed, itโ€™s sort of the point. But itโ€™s also sort of absurd to act like getting a warrant to execute a home arrest is some crazy insuperable barrier.
