 Church officials have argued the Navy 's records were " not only grossly incomplete but perhaps were falsified to conceal Hubbard 's secret activities as an intelligence officer . " In the 1980s the Church turned to L. Fletcher Prouty , a former U.S. Army colonel , who said that Hubbard 's records had been falsified to cover up his " intelligence background " . Prouty , who died in 2001 , was a prominent conspiracy theorist best known for advocating John F. Kennedy assassination conspiracy theories and was also associated with the anti @-@ semitic Liberty Lobby group and the Lyndon LaRouche organization .
