The Metropolitan Police of St. Louis drove 1928 Packards with shiny bells on the front.
The Chicago Police, on the other hand, drove Fords and some green 1928 Cadillacs with black fenders. Behind the front grill, the Caddies were equipped with flashing red lights and a siren.
So, you may ask, what did Al Capone drive?
Al Capone also had a green 1928 Caddy with black fenders, a siren, flashing red lights, and a police band receiver. It was the twin of the police issue. In addition, it had 3,000 pounds of lead and one inch bulletproof glass all around. Capone’s 1928 Cadillac was so well fortified that for his own protection President Roosevelt used it after the attack on Pearl Harbor in December 1941.
