(a) Whether individuals crossing or attempting to cross an international border with travel documents belonging to other persons or without travel documents are perpetrators or victims of trafficking in persons;
(b) The types of travel document that individuals have used or attempted to use to cross an international border for the purpose of trafficking in persons; and
(c) The means and methods used by organized criminal groups for the purpose of trafficking in persons, including the recruitment and transportation of victims, routes and links between and among individuals and groups engaged in such trafficking, and possible measures for detecting them.
2. States Parties shall provide or strengthen training for law enforcement, immigration and other relevant officials in the prevention of trafficking in persons. The training should focus on methods used in preventing such trafficking, prosecuting the traffickers and protecting the rights of the victims, including protecting the victims from the traffickers. The training should also take into account the need to consider human rights and child- and gender-sensitive issues and it should encourage cooperation with non-governmental organizations, other relevant organizations and other elements of civil society.
