@StuC Well, I'm guessing you got the results *I* was expecting. :P

@phryk the tech seems to use common communication protocols, GPS, GSM and BT

It would be interesting to examine one for conceptual and technical weaknesses...

I'd guess the best place to start would be to see if you could spoof the presence of the bracelet to the base station. Then you could simply offline the bracelet itself (GSM Jammer, Faraday cage, microwave oven, Hammer) and go for a beer.

@StuC @phryk I mean, GPS isn't hard to spoof, but it's a little too obvious to the people around you

@artemist @phryk GPS inside a building is as much use as a chocolate fireguard.

I presume the GPS and GSM functionality are largely used when the subject has moved outside the range of the base station. As long as the base station thinks it is in BT contact with what it thinks is an untampered bracelet it'll happily check in with the mothership and announce that all is well.

It would be nice to source even an older model and have a play.

@StuC @phryk oh, I didn't know there was a base station. I wonder if you can wormhole the BT connection

@Antanicus Sadly, nothing in English.

Here's a few German ones:

https://netzpolitik.org/2018/das-steckt-drin-uebersicht-zum-neuen-polizeigesetz-in-niedersachsen/ (on lower saxony)

https://www1.wdr.de/nachrichten/landespolitik/polizeigesetz-gefaehrder-rechtsstaat-100.html (on NRW)

Actual specifics on the NRW one seem impossible to find on the web, my best information on this is from a mailing list.

@Antanicus But all three seem revolve around introducing the concept of "drohende Gefahr" ("looming danger") as opposed to the classical "konkrete Gefahr" ("concrete danger").

A "looming danger" does not have to be proven, based on reasonable suspicion or anything else. It's a blank-slate cheque for the piggos to punish and abuse anyone they want.
