Human Rights Watch researchers spoke regularly with representatives of all main political parties and movements during the course of this research to follow human rights abuses and other acts of violence targeting political parties. Information provided by political party activists that is presented in the main text of the report was in almost all cases cross-checked with other sources, including officials from other political parties. Police and judicial officials provided further information on arrests of party activists and acts of political violence, as well as the status of investigations into these abuses.
