Wired’s Threat Level blog has the story of California student Yasir Afifi. His mechanic found an unusual electronic gadget in Afifi’s car, that turns out to be a tracking device. Then he posted pictures to Reddit. Interestingly, the crowd-sourced analysis pegged the exact make and model of the tracking device, an Orion Guardian ST820 by Cobham, price tag $5k-$6k or so. The FBI came calling the next day and retrieved the device.
