jamie writes "A comment posted to a website got its author's *friend's* car an unwanted aftermarket addon. The Orion Guardian ST820, a GPS tracking device, was attached to the underside of the car by the FBI. No warrant required. The bugged friend, a college student studying marketing, was apparently under suspicion because he's half-Egyptian. As Bruce Schneier says, 'If they're doing this to someone so tangentially connected to a vaguely bothersome post on an obscure blog, just how many of us have tracking devices on our cars right now ...' The ACLU is investigating." This follows up on our earlier mention of the same student, who turned the tracking device over to the FBI.
