TRIVIA NOTE: The series was made in cooperation of the Metropolitan Police and the citizens of London. The "9-9-9" emergency phone service originated in England on June 30, 1937. It was the first service of its type in the world. In 1968, the United States implemented an equivalent system ("9-1-1")  in Haleyville, Alabama.
