      Not at the same scale as mobile traffic

      Bluetooth by definition doesn’t go much past 10-20 meters

      Super easy. You can also do basic triangulation with some specialty hardware.

        But we’re talking about a protest where bad actors (the police) just want the names of its attendants. Our phones scream to everyone “I am [name surname] and I am here!”. Bluetooth instead says the same but with a lower tone of voice, so less people can listen. Also, with little configuration you can instruct it not to broadcast its identifier.
