After wishing for years to be given-the-opportunity of filming some of the more "mystical" occupations of our Times - some of the more obscure Public Figures which the average imagination turns into "bogeyman" ... viz: Policemen, Doctors, Soldiers, Politicians, etc.: - I was at last permitted to ride in a Pittsburgh police car, camera in hand, the final several days of September 1970 - this opportunity due largely to the efforts of a Pittsburgh newspaper photographer, Mike Chikaris - who was sympathetic to my film show at the Carnegie Institute and responded to my wish as stated on that occasion - therefore pleaded my "cause" eloquently with Police Inspectors of his acquaintance: my thanks to him, to Sally Dixon of the Carnegie Institute and to the Policemen who created the situation that made this film possible.
