New submitter Lew Lorton notes a NY Times story about a thief in New York City who was tracked and located using a GPS device inside a decoy pill bottle he had stolen (along with other pill bottles) from a pharmacy. When police confronted the thief, he raised a gun to shoot at an officer, and was killed "The decoy bottles were introduced last year by the police commissioner at the time, Raymond W. Kelly, who announced that the department would begin to stock pharmacy shelves with decoy bottles of painkillers containing GPS devices. The initiative was in response to a sharp increase of armed and often deadly pharmacy robberies across the state, frequently by people addicted to painkillers. ... The bottles are designed to be weighted and to rattle when shaken, so a thief does not initially realize they do not contain pills. Each of the decoy bottles sits atop a special base, and when the bottle is lifted from the base, it begins to emit a tracking signal."
