MEXICO Freedom of the press in Mexico oscillates between the president's pledge to respect it and the desire of some bureaucrats to prevent it, at times violently. There is no restriction on freedom of expression or censorship but journalists are unsure what price they might have to pay for exercising this right. President Carlos Salinas de Gortari's administration is keeping its promise to maintain the free flow of ideas: on April 20 it ended a 54-year newsprint monopoly by the state-owned PIPSA and opened the border to imports. PIPSA continues to grow financially but is no longer is a Damocles sword hanging over press freedom in Mexico. Privatization of PIPSA, another of the presidential promises, has not yet been achieved, but the government stresses that it remains willing to sell it. The PIPSA board of directors, comprising representatives of major newspaper publishing companies, wanted newsprint production to remain in state hands. But by allowing free import of newsprint, the government heeded those who are opposed to newspaper production being dependent upon the government. Journalist Jorge Castafieda and his secretary received a death threat from armed individuals June 15 and again after reporting the matter to police. President Salinas personally issued a statement from Tokyo, where he was on an official visit, condemning the incidents and reiterating his respect for freedom of expression, and called Castaneda to offer support. The incident remains under investigation. Rodolfo F. Pena, a writer for La Jornada,said July 2 he had received telephoned death threats. The Federal district attorney general's office provided special protection for him while it investigated the complaint. April 17, Mexico City police arrested the publisher of the magazine La Trilla on the pretext of investigating the illegal acquisition of the publication's machinery.
