Police using Flock to warrantless follow people across state lines is an act incompatible with our legal system--especially in a country where many things are legal in some states in criminalized in the other. First we saw it with abortion care, now we will see it with marijuana.

Cops Used Flock to Track a Man Across State Lines to Create Pretext to Search His Car for Weed

"The vehicle travels to Michigan frequently which is a known source state for marijuana as it is legal there," a probable cause justification reads.

In light of the revelation today of DHS’s massive operation to spy on social media critics of their policies, remember this I posted a few months ago about the tech they bought that can do just this—and how the company markets itself to do political surveillance.

Just learning that ICE has a $4.2 million contract for social media surveillance/AI analysis with Fivecast. A few years ago I came across a brochure of theirs which used as an example for potential police customers their ability to map left-wing groups. www.eff.org/deeplinks/20...

Ok book lovers and friends. If I haven’t convinced you yet to buy “Your Data Will Be Used Against You” can the combination of John Oliver and BookTV be enough. Banner day for the book. (Also the issues are super important to our future).

This week’s main story is about how police use surveillance tools like cameras, microphones, license plate readers, “cell site simulators,” and the practice of “predictive policing,” to create a world that has been lovingly described as “Big Brother on steroids.” Full segment at the link in our bio.

Proof of the importance of legal protections, counsel, courts, and a system designed to push back against politicized prosecutions. But this is not a story about how the system worked, but about how it has been corrupted. Anyone could be next. www.washingtonpost.com/politics/202...

Now is the time to debate new forms of self-surveillance. Flock is just one tool of a growing surveillance architecture. As I write in “Your Data Will Be Used Against You: Policing in the Age of Self-Surveillance” these are our tax dollars being used to surveil us. www.cbsnews.com/minnesota/ne...

Weird that this article does not mention that Code Four uses AI to take the video of police worn body cameras and turns them into written AI drafted reports. VLM being used to write affidavits deserves a bit of critical assessment which is lacking in this article. statescoop.com/police-ai-pl...

In Chatrie v. United States, the Supreme Court confirmed the Fourth Amendment is relevant to the digital age. I think it offers a reimagining that impacts all sorts of digital surveillance beyond geofence warrants. Here is an essay on what it means for the future. papers.ssrn.com/sol3/papers....

This is amazing. A single 77 guy staging a protest against Flock cameras. It reveals the depth of people’s frustration with growing networks of self surveillance. And yet reveals three deep misunderstandings of the challenges ahead. 1/5 www.cltampa.com/news/a-77-ye...
