Carter investigated the flow of money in the New York/New Jersey prostitution network, and she began to build a case of prostitution racketeering founded on evidence from interviews with prostitutes and wiretaps.[46] On February 2, 1936, Dewey authorized Carter to raid 200 brothels in Manhattan and Brooklyn, earning him nationwide recognition as a major "gangbuster". Carter took measures to prevent police corruption from impeding the raids: she assigned 160 police officers outside of the vice squad to conduct the raids, and the officers were instructed to wait on street corners until they received their orders, minutes before the raids were to begin.[47] Ten men and 100 women were arrested.
