Hello new followers! I wrote a book--Police and the Empire City--which explores how the New York City police department's encounters with race, immigration, and empire shaped how modern police use technology, recruit, do violence, and operate generally.

I spent the week at the police surveillance convention and let me tell you my biggest observation: The name of the game now is consolidating as much information as humanely possible from surveillance devices, the internet, other governmental data, and literally a million other places. 🧵

New: Records obtained by the @aclum.bsky.social show police across the state are conducting dragnet surveillance of motorists and sharing their location information with cops in states that have banned abortion and gender affirming care, and those that work w/ICE data.aclum.org/2025/10/07/f...

A county commissioner tried to take down a License Plate Reader in his jurisdiction where elected officials had ended their contract w/ Flock. Police arrested him.

Who really runs these counties? Politicians gave blank checks to police and are now learning the genie is out of the bottle.

🚨🚨 Both the police and Flock's defense for why Texas police searched the entire country for License Plate Reader data to find woman who had self-administered an abortion was because she was a missing person and family was concerned with her health. Now documents reveal they wanted to charge her.
Police Said They Surveilled Woman Who Had an Abortion for Her 'Safety.' Court Records Show They Considered Charging Her With a Crime
Court records show that the narrative Flock and a Texas Sheriff's Office has told the public isn't the whole story, and that police were conducting a 'death investigation' into the abortion.

To put it another way, I have represented thousands of people. I cannot think of a single instance in which the initial police report was entirely correct. Not one.

Journalists, please stop copying them down as if they were. Or at least give context re credibility!

Whether you're a casual news reader or a breaking news reporter at the NYTimes, I implore you--please, please, please--do not believe or report DHS/ICE/CBP's side of events uncritically. End the state's monopoly on legitimate storytelling. They are not the objective arbiter of what really happened.

Body-camera video appears to contradict the government’s claim that Marimar Martinez, 30, drove toward officers before one of them opened fire at her late Saturday morning in Brighton Park, her attorney claimed.

We'll see how much longer it's available after this!

A lot of people who have ignored this are also about to learn really *really* quickly that when police control when cameras turn on, footage storage, and release of footage, body-worn cameras are much more a tool of surveillance and state propaganda than accountability.

Who could have predicted that third party verification programs collecting IDs to age gate content would have all their data hacked?! Oh right…..everyone!

NEW: breach of Discord age verification data.

Including some users passports & DLs

Age verification is a badly implemented data grab wrapped in a moral panic.

Mark my words, as age verification mandates expand, we'll end up more surveilled and less secure. 1/

A San Francisco Supervisor wants to amend a landmark surveillance law so it is harder to sue police when they spy on you illegally. Police are not above the law and this policy change will result in one thing: more illegal surveillance. www.eff.org/deeplinks/2...

My response to Ring's decision to roll back reforms and go back to surveillance on behalf of police as a business model.

This is part of a trend of companies bending over backwards to get in on the techno-authoritarian money/power grab that comes with being a lapdog of the carceral state.

Ring founder Jamie Siminoff is back at the helm of the surveillance doorbell company, and with him is the surveillance-first-privacy-last approach that made Ring one of the most maligned tech devices....

I’m watching the Jonathan Demme/Denzel Washington Manchurian Candidate remake and not only do I think it’s fantastic—I also think it might be a defining film to capture the era of the endless war on terror.

Ads reveal that Flock, makers of automated license plate readers and other surveillance technology, are promising to introduce "Distress detection" into their gunshot detection devices which will alert police when it hears human voices in distress, including screaming.

An add that says "Safety you can see and now hear: Detect sounds of human distress and cover the blind stops that cameras miss with Distress Detection" with an alert that says "screaming" and an address.

“The judge or the prosecutor doesn't know which portions were written by the AI and which portions were written by the officer,” EFF’s @MGuariglia.bsky.social told KPBS News. “It interjects a lot of uncertainty — and a lot of deniability for the officer.” www.kpbs.org/news/public...

It amazes me that politicians continuously sell us the idea of policing as the only route to peace and safety when with our own eyes, everyday, from the Punisher logo to this, we are forced to confront the fact that they outwardly present themselves as a death and violence cult.
