In some other respects effective criminal law should be more expansive than the provisions of the Protocol.  For example, the International Human Rights Law Group advises broadening the scope of domestic legislation in so far as who can be prosecuted.  Article 4 of the Trafficking Protocol states that its provisions apply to the prosecution of offenses that "are transnational in nature and involve an organized criminal group."  As Ann Jordan, the author of the Annotated Guide to the UN Trafficking Protocol, indicates, the Protocol does "not cover trafficking by one or two persons or internal trafficking that has no international aspect.  . . . Also not covered is trafficking that is done entirely within a country by nationals of the country."  Thus, effective domestic legislation should punish individual traffickers and organized crime groups for both cross-border and internal trafficking.
