The billionaire media is laying off great tech journalists in crazy quantities this year - replacing them with AI and sycophants. This would be a great time to throw some dollars, euros, pounds, or dollarydoos to @404media.co, @propublica.org or another independent outlet.

ICE Is Grabbing Data From Schools and Abortion Clinics An agency database WIRED obtained reveals widespread use of so-called 1509 summonses that experts say raises the specter of potential abuse.

“The outlier cases include custom summonses that sought records from a youth soccer league in Texas; surveillance video from a major abortion provider in Illinois; student records from an elementary school in Georgia; health records from a major state university…”

DHS Hunts Down 67-Year-Old U.S. Citizen Who Criticized Them in Email The Department of Homeland Security is using a little-known tool to go after its critics.

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.

Homeland Security is targeting Americans with this secretive legal weapon Under Trump, the Department of Homeland Security has weaponized administrative subpoenas to attack free speech, according to privacy and civil rights groups.

Read this:

A knock on the door to intimidate.

A requests to Google for personal data.

Government surveillance for mild criticism.

Misuse of legal process.

Great talk with @profferguson.bsky.social about how data collected by private companies, including from devices in your own home, is so easily weaponized against you and what we should do to protect our civil liberties.

Marvelous interview. Breaks down intersection of 4th Amendment, creeping invasion of privacy by all manner of law enforcement, & tech overreach in plain language, terrific explainer.

If you are worried how data will be used against ICE protesters.

Or how smart homes reveal your secrets.

Or smart cars or medical devices will become evidence in court.

Listen to this conversation.

There are risks, rewards, and even solutions…

“As the New York Times recently reported on Friday, tech companies are enabling a surveillance infrastructure that can target anyone for profit while challenging constitutional principles. And we have few laws that are fit to regulate it.”

Hardly evidence of any success… to prove your point. It was the first warning article about how prosecutors (as opposed to police) were weaponizing predictive policing. And basically talks about the failed Chicago Heat list. Odd.

Third, as uncomfortable as it is to say, this is a form of democratic self-surveillance because we have given the green light to fund and allow the tech. We could stop it tomorrow if we wanted to regulate it. We haven’t and we got this danger. For more…

Second, there is nothing stopping other law enforcement (the FBI) from using the same tech on those who went to “No Kings” protests or just expressed their disapproval of these tactics. Congress and the courts could act, but have not. You are just as vulnerable. 3/4

First, this is as bad as it looks when an unchecked law enforcement entity is using powerful tracking and identifying tools against the most powerless. 2/4.

Yes. I remember being on a podcast with @jordanuhl.com in Trump 1.0 and warning how immigration would be the way surveillance infiltrated ordinary policing. Start with the most powerless. Wonder if that still exists somewhere in the interwebs.

The powerful tools in ICE’s arsenal to track suspects — and protesters Biometric trackers, cellphone location databases and drones are among the surveillance technologies agents are using in their immigration enforcement campaign.

This is the beginning not the end of how surveillance will change America. We could stop it. We should. www.washingtonpost.com/technology/i...

This paper elucidates the way “geofencing” practices currently used by law enforcement effectively and dangerously circumvent our 4th Amendment rights as outlined by the Constitution:

A very big deal. See how happily DHS and White House staff declared folks who their agents killed were "domestic terrorists?"

It's not only protesters who'd be targeted.

Your coincidental proximity to any event, not just protest, could be distorted into a basis to act against you. And, for sweeps!

Important thread following the through line of our location data, our very tangible civil liberties, and the way an upcoming Supreme Court decision (Chatrie) could enable the ways in which the govt surveils and targets you (yes, YOU), individually and specifically

Also, Congress could step in and resolve the whole thing… but they won’t so it is up to the lawyers.

Otherwise your data is going to be used against you. 12/12
