I saw a story about a fire in a bar that was blamed on a faulty receptacle. Several weeks later someone found a tape in the burnt up VCR and found it was actually viewable. When they viewed the tape it was seen that a waitress cleaning up dump some cigarette butts into t rash can under the "defective receptacle'. The trash started to burn. It had nothing to do with the receptacle but since it was in the vicinity of the point of origin they assume the receptacle was the cause.
