Non-governmental human rights organizations, including medical organizations, or any other body engaged in monitoring and advocacy, may uncover evidence of torture and other ill-treatment during their work. Through a combination of meticulous research including field-work, interviews with survivors and families, meetings with public officials, information from the media, and cooperation between organizations, it may be possible to identify a pattern of human rights abuses that may not have been evident when viewing each source separately. This is often the way in which systematic torture and other ill-treatment come to light.
