“Summary of conditions: Vice conditions in this city are extremely bad. Gambling, bootlegging and prostitution are very much in evidence. At the leading hotels and looming houses the bell hops and porters are pimping for women, and also selling booze, [r]egarding violations of the law, these prostitutes and pimps solicit without any fear of the police, as they will invariably remind you that you are safe in these houses” (Federal Report on Vice Conditions in Tulsa).
