Four members of the Minnesota Vikings, including injured star quarterback Daunte Culpepper, were charged with indecent conduct, disorderly conduct and lewd or lascivious conduct for their actions during a charter boat cruise on Lake Minnetonka in October.  The football players avoided facing much more serious federal charges because among the female guests was an exotic dancer and others who traveled from out of the state to attend the party and were compensated for attending.  The Mann Act, 18 U.S.C. Sec. 2421, provides: "Whoever knowingly transports any individual in interstate or foreign commerce, or in any Territory or Possession of the United States, with intent that such individual engage in prostitution, or in any sexual activity for which any person can be charged with a criminal offense, or attempts to do so, shall be fined under this title or imprisoned not more than 10 years, or both."  An AP story (here) notes that the U.S. Attorney for the District of Minnesota declined to pursue such charges because of "insufficient evidence."
