"The United Nations (UN) has played an increasing role in promoting the safety of journalists. Yet little has been done to study its work from a historical perspective. This paper explores global attempts to promote journalist safety carried out by the UN system, from its inception in 1945 until 2016. It also analyses the past to ascertain the relevance of the UN Plan of Action on the Safety of Journalists and the Issue of Impunity. Never since its approval in 2012 has the UN progressed so much in such a short time in this field of normative work. This affords a historic opportunity to tackle this issue meaningfully." (Abstract)
