Lol. Axon: "We ain't them Flock snoopers you've learned to hate: we're a whole 'nother snooper you ain't hated yet!" 😆

Cops asked Axon to change their camera's shape "for the optics" while they "batten down the hatches." Same warrantless plate-tracking, new disguise. 👀

Let us paint a picture:
- Discovery requests are due
- There’s some weird tech at play that you haven’t seen before or don’t know much about
- You’re not sure what’s happening or what to ask for
- Maybe you’re a little stressed

Sound familiar?

Sadly, this news doesn't 'shock' us. Aggressive police tech & surveillance in schools have become the norm for youth today. More on this topic in our forthcoming report, "Algorithmic Adolescence." apnews.com/article/shoc...
Nebraska's largest school district asks police to stop using electric shock gloves on students

ALPR systems like Flock track more than your license plate! They can also do pattern analysis and search by “a place, a stretch of time, and a pattern of behavior.” Sound familiar? A virtual panopticon by any other name… www.wired.com/story/flock-...
Flock Has a Powerful New AI Tool for Police. We Got Its Code
Flock’s surveillance cameras have already sparked outrage. WIRED reconstructed its next-generation AI system, already in use by some police, to confirm it goes much further than tracking license plate...

🧵First came the Flock cameras. Now come the drones.

Hundreds of police departments are rolling out autonomous, AI-driven surveillance drones that can follow one car across a whole city and film through your apartment window. A new @truthout.org report lays it out.

"I don't think judges understand the country is now blanketed with these things and they're all interconnected."

That is Sid Thaxter of NACDL's Fourth Amendment Center in The New York Times on Flock's creepy license plate cameras. They read your plate everywhere you drive. And they never forget.

BIG Fourth Amendment win.

"Tower dumps are per se unconstitutional general warrants," U.S. District Judge Carlton Reeves held last night in Mississippi.
The court relied on Chatrie and Smith, landmark NACDL Fourth Amendment Center victories.
