If you live in Bath and have your Bluetooth on you might want to turn it off.

Apparently over the past 6 months an experiment has been taken place using the citizens of Bath as unwitting surveillance guinea pigs.

“…Kostakos’s have an even more frightening idea. Why not test the idea by anonymously monitoring the movements of students, residents and workers of the city of Bath by listening out for their bluetooth-enabled devices as they move around the city. And that’s what they’ve done.”
