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."
