Take one old Ruger 10-22 rifle, some electronics gear, a long can antenna, and some time to spare, and you too can be The Bluetooth Sniper...

Apparently, these guys built a Bluetooth rifle and managed to stand on top of buildings in downtown Los Angeles without getting corralled by the police. In the process, they were able to connect to Bluetooth devices nearly a mile away:

"As more Bluetooth devices started appearing, John said, "This building is full of Bluetooth! Look we got some Blackberries!" He also explained that, with multiple guns, it would be possible to track a single Bluetooth device as the person walked around. In less than a few minutes, twenty devices were detected—all at distances over a half mile away! We decided to quickly conclude the scan, given police activity in the area earlier in the day from a bomb scare."
