Is anyone familiar with the laws surrounding police basically operating their own pseudo cell towers? I would assume this would be highly illegal for individuals, what sort of hoops did law enforcement need to jump through to get this type of approval? Did FCC need to rubber stamp this?

Great video, thanks for posting. Since Meshtastic keeps coming up in the video — if anyone here is heading to Burning Man, there's a dedicated mesh network for the event. I will have a couple nodes running on it :) https://www.burningmesh.org/

I'd love to know how it does. One of meshcore's claims is that it scales better than meshtastic. The 900 MHz band is limited and herding cats without a shepherd is a hard problem. Music festivals are a good stress test.

John Oliver did a piece on this a couple of weeks ago. The videos are not widely available outside of the US, but here's a Guardian write-up [0], and in the UK you can get access to the episode via catch-up if you have Sky Atlantic. TLDR: the police do this whenever they want, pretty much. [0] https://www.theguardian.com/tv-and-radio/2026/aug/03/john-ol...

In the US, the legality of Flock cameras is complicated. =3

Partial summary: -ESP32 based device that tries to detect bluetooth/MAC addresses of flock cameras and beeps when it does - a Stingray detector that runs on a second-hand mobile hotspot - a device that alerts you about things that are moving approximately with you (AirTags, SSIDs, etc).

Cell phone connectivity was the beginning of the end for burning man.

CSS - chirp spread spectrum is used by both, so likely better software

I'm not sure I understand Simulacra. I get the idea, just spam devices around the area in hopes you're lost in the crowd. But anything designed to track you is purpose built to handle tons of devices moving about. Maybe if everyone had one in their pocket we could overload the surveillance devices, but at best you're just bloating their logs.

Seconding this, plus, the original devices stays always visible to the tracker? Does it really matter if there's your sole device in the range, vs always-present yours + ton of noise?
