The right of citizens to know what is happening within the government and in the ordinary street is one of the factors that drive journalists while a tool used by the government to restrict journalists is to classify some documents and information as “Official Secret Act”, “National Security” and “Internal Interest”. These are used to cloak the government’s illegal spying activities. It is against this background that this research examines National Security and the Right of the public to know: An analysis of Samuel Ogundipe Experience. The study was anchored on Social Responsibility Theory. Survey research method was used while one copies of qustionanire were administered to journalists in Portharcout.
