“ Thus the Court today applies the White Slave Traffic Act, 18 U.S.C.A. § 397 et seq., to a case of voluntary prostitution, despite the fact that none of the elements of white-slavery is present. Equally disregarded is the fact that Congress clearly intended such conduct to remain punishable under local laws and that adequate local laws for the District of Columbia have been provided by Congress to cope with the real evils present in this instance. Such facts make it unnecessary to invoke the White Slave Traffic Act as a means of controlling voluntary vice in the District. ”

“ That courts in the past have ignored the plain Congressional purpose and have applied these statutory words in a literal sense, so as to punish anyone transporting a woman for immoral purposes quite apart from any connection with white-slavery, does not command us to continue such an erroneous construction and application of the Act. ”

“ Many men earned their livelihood from the sale and exploitation of these women. State laws were found entirely inadequate to cope with such an extensive international and interstate traffic.
Congress, however, was careful to distinguish this vicious traffic from immorality and prostitution in general. It made it clear that the Act was aimed solely at the white-slave traffic, which was explicitly defined as 'the business of securing white women and girls and of selling them outright, or of exploiting them for immoral purposes.'
