Taking women across state lines for immoral purposes (Victorian euphemism for illicit sex and usually prostitution) is a violation of federal "White Slavery Acts." I know of no statute prohibiting the sending of lavender queens across state boundaries to indulge in their hobbies. The hobbies may well be crimes especially when perpetrated against the young but the crossing of state borders would not seem to be. Liberals call that the "right to travel" which was discovered by the late Justice William Brennan rooting around in the liberal toolbox of the Fourteenth Amendment "equal protection" clause in the matter of Shapiro vs. Thompson (ca. 1968-70) involving the former Connecticut six-month waiting period before residents of other states could collect colossal Connecticut welfare payments by moving to Connecticut from, say, Mississippi. In any event, crossing state borders as such, regardless of purpose, does not seem to violate RICO.
