Police had no suspect. So they got a warrant for every phone Google tracked inside a circle on a map. The Supreme Court ruled 6-3: that's a Fourth Amendment search. Jumana Musa (@nacdl.org) joins Hunter.

A charcoal card from the Public Defenseless Podcast, Episode 517. Red text reads "No suspect. No leads." Beside it, a red outlined circle holds 19 dots, 3 of them red. White text reads "Just a circle on a map, and every phone Google tracked inside it." Grey text adds "The Supreme Court: that's a Fourth Amendment search." A pull quote reads "Whatever your belief system is, the government doesn't belong in it unless they can actually tell a judge why something illegal has happened and why they believe you have been implicated." It is attributed to Jumana Musa, Director, Fourth Amendment Center, National Association of Criminal Defense Lawyers. Red text at the bottom reads "Now available to Patreon subscribers," above linktr.ee/pdefenselesspodcast.

Police got one warrant. After that, they and Google narrowed the list between themselves, no judge in the loop. Jumana Musa on the Chatrie ruling: pulling your location history is a Fourth Amendment search.

🧵A surveillance vendor is telling police it can add facial recognition to Flock camera data. Flock says it never will. Someone else is ready to jump in.

Surveillance tech doesn’t distinguish between red and blue. Americans are crossing the aisle to stand up for civil liberties.

It’s not just Flock that has people upset. When @4ac.nacdl.org litigated Chatrie v. United States to challenge geofence warrants, groups from across the political spectrum joined in support of privacy rights for cell phone location data.

The article finds that “This year, more than 100 governments in blue and red towns have paused or ended Flock contracts, according to DeFlock, an opposition group. Local residents are organizing, protesting and digging through records.”

From liberal Asheville, NC to conservative Oconee County, SC, communities are fighting back against government surveillance. Within days of each other, both places voted to stop using Flock cameras.

The nationwide backlash against automatic license plate readers is “uniting Trump country and progressive strongholds alike,” according to the Wall Street Journal.

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. 👀

Same snooping. New disguise. Cops asked Axon to redesign its license-plate cameras so the public won't recognize them. Warrentless tracking of every plate that drives past.

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...

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-...

What does the Supreme Court’s Chatrie decision mean for ALPRs like Flock?
