1The Nassau County Police Department was created in 1925 out of an urgent need for a professional law enforcement agency to provide swift, reliable, and trusted protection for its citizens. During those unprecedented times, Greater New York was rapidly encroaching on Nassau County's western border, and the escalating crime rate in this bucolic island setting was due in large part to the Volstead Act, which ushered in the mob-infused Roaring Twenties, with its related violent and turbulent unrest. After the rebellious 1920s and the Great Depression followed a long dark period of global hostilities and impending threats of homeland invasions from foreign enemies in World War II. The founding members of this department, equipped with little other than their dedication, bravery, fortitude, and self sacrifices, established a strong foundation for one of the finest police departments in the country today.
