Digital Camouflage Shirt vs AI Surveillance [2026]

Berlin artist Simon Weckert unveiled Digital Camouflage, a shirt engineered with adversarial patterns that can intermittently fool open-source YOLO person detectors while remaining visible to humans.

Simon Weckert's Digital Camouflage shirt breaks open-source YOLO person classification in controlled demos — but the wearer's face stays visible, and real surveillance pipelines chain multiple models.

Gardner, Kansas became the latest city to shut down its Flock Safety license plate readers, after a resident-led campaign flagged that more than 1,200 vendors had access to the data.

SparrowMap is a volunteer camera network that flips automated license plate recognition around: it keeps the photo and plate only when the vehicle is government-owned, and destroys everything else on the device before it ever reaches a server. Here's how the project works, what the Hacker News debate around it revealed, and how to handle the ordinary people your own camera catches along the way.

Body Camera Footage Redaction: FOIA Fines & Rulings [2026]

Connecticut fined New Haven $1,250 for a body-camera request that sat 20th in a redaction queue for nearly three years. A DC court forced the release of 1,627 January 6 bodycam videos after rejecting the department's blanket-blur plan. "We can't redact it" has stopped working as a public-records defence — here's what actually has to be blurred, why frame-by-frame redaction is the bottleneck, and how motion-tracked automated blur changes the cost math.
