4. Medical malpractice. Here’s why I say stopping this detention-to Texas pipeline is life of death.

An 18-month old hospitalized after nearly dying of three simultaneous respiratory infections. When she returned to the camp, DHS withheld her meds.

We now have data from Trump's first full year in office. Let's review the performance of Trump and the two parties since 1989 and a new age of globalization began.

However you cut the data Trump continues to have worst jobs record of last six Presidents. 1/

I realized that I hadn't posted my visualizations of the *index* of a vector field on bsky! Pick a point where v=0, and take a tiny circle around that point. Walk around the circle (blue dot on the left) counterclockwise, noting where the vector field points (orange arrow). 1/9

1/ ProPublica collected handwritten letters in mid-January from children held at the Dilley Immigration Processing Center, the same facility where 5-year-old Liam Conejo Ramos was taken.

Hundreds of kids are still detained.

ICE told nurses this Minneapolis man “purposefully ran headfirst into a brick wall.”

What actually happened is that they pulled him from a car, beat him so viciously with a steel baton that he had 8 skull fractures, 5 life-threatening brain hemorrhages, and couldn’t remember he had a daughter.

Full on concentration camps. "We don't know half of what's going on in the camps, but we know enough" is echoing from 85 years ago.
Kelly Vargas writes about what happened to her, her husband, and their 6yo daughter in the family camp in Texas.

Filth, illness, medical abuse—her child has lasting complications from being injured by a staff member.

We don't know the half of what's happening in the camps, but we know enough.

Floored by this story. A man wrote a pollite email to a federal prosecutor objecting to the deportation of an Afghan seeking asylum. DHS responded with an administrative warrant to get the man's info from Google, then visited his home to intimidate him.

Popping out of the vehicle guns drawn and pointing them at a legal observer exercising her constitutional rights.

Everything about this is reckless, dangerous, the opposite of law & order and keeping anyone safe… how do people see this and not see masked secret police style terror on US streets
This is just insane. It’s only a matter of time before DHS kills another innocent person here.
