The climate of press freedom in Mexico, despite a new president, remained perilous. Although President Enrique Peña Nieto gave final approval to a measure adopted at the end of Felipe Calderón's term that gives federal authorities broader jurisdiction to investigate crimes against freedom of expression, the special prosecutor's office designated to handle such investigations dragged its feet in exercising its new powers. Finally, in August, the prosecutor officially took on its first case, although it had not charged or prosecuted anyone for a journalist's murder in late year. Meanwhile, the press corps continued to be violently targeted as competing drug cartels and law enforcement and the military battled throughout the country. Media outlets were attacked, press freedom organizations threatened, and reporters abducted. At least three journalists were killed in 2013 under unclear circumstances. In the face of such violence, media outlets in areas controlled by cartels turned to self-censorship. Following in the footsteps of other besieged outlets, the Saltillo edition of the daily Zócalo published an editorial that said it would no longer cover organized crime, as a way to protect its staff. Mexico City, long considered a refuge from the violence in the rest of the country, experienced the encroachment of organized crime. Four journalists covering protests against education reforms were jailed, and two of them were held for five days before being released on exorbitant bail, according to news reports. Media analysts welcomed a communications bill that they said would increase competition and open up broadcast ownership.
