Did Ritter cross a state line with the prohibited intent to engage in a sexual act, or did he engage in such a prohibited sexual act "in the special maritime and territorial jurisdiction of the United States"? Maybe there's some case law or legislative history indicating he did, but, without such authorities, it's certainly not clear to me.
