High school senior, a U.S. citizen, detained by ICE in Oregon The 17-year-old was held more than five hours Friday in an ICE facility, his brother said.

The teenager told officers he was a U.S. citizen, but an officer broke the car’s driver’s side window and detained him. In a video, the boy can be heard telling an officer that he is a citizen, to which the officer replies, β€œGet out of the car” and β€œI don’t care.”

That MAGA Account Might Be a Troll From Pakistan How X blew up its own platform with a new location feature

I wrote about the fake account blowup on X this weekend. A genuine post-truth nightmare and proof that these companies have polluted their platforms so thoroughly and traded reality for profit that they've undermined the very idea of what the internet is supposed to be.

DHS quietly corrects inaccurate information after Charlotte Observer report As Border Patrol arrived in Charlotte, DHS falsely said a Honduran man charged with murder was released under NC’s β€œsanctuary policies.”

DHS claims that an accused murderer was released from a Charlotte jail and was β€œback onto North Carolina’s streets because of sanctuary policies.”

The local paper reported that was false.

So DHS quietly removed that statementβ€”and never admitted they lied. www.charlotteobserver.com/news/local/c...

By and large, however, the allegations against the other social media platforms are less detailed than those against Meta. The internal documents cited by the plaintiffs allege:

Meta intentionally designed its youth safety features to be ineffective and rarely used, and blocked testing of safety features that it feared might be harmful to growth.
Meta required users to be caught 17 times attempting to traffic people for sex before it would remove them from its platform, which a document described as β€œa very, very, very high strike threshold."
Meta recognized that optimizing its products to increase teen engagement resulted in serving them more harmful content, but did so anyway.
Meta stalled internal efforts to prevent child predators from contacting minors for years due to growth concerns, and pressured safety staff to circulate arguments justifying its decision not to act.

It's hard for USGs to claim β€˜mistake of law’ or β€˜advice of counsel’ – when they’re firing lawyers who wouldn't sign off on the strikes.

The Dept of Education no longer classifies Nursing or Accounting degrees, among others, as "professional" when considering reimbursement for federal loans.

Two professions where shortages are rampant. Ain't gonna get better with this!
