Brazil played an increasingly dominant role in the international arena, but its record on press freedom at home continued to disappoint free-expression advocates. As the deadly violence that surged over the past three years continued, three journalists were murdered in direct retaliation for their work in 2013. Brazil's ranking worsened on CPJ's Impunity Index, which highlights countries where journalists are killed regularly and authorities fail to solve the crimes. In positive developments, authorities achieved convictions for three murders of journalists. The gunmen in the 2010 murder of radio journalist and blogger Francisco Gomes de Medeiros and the 2011 murder of journalist Edinaldo Filgueira were convicted and sentenced to prison. In a rare example of full justice, all of the perpetrators, including the mastermind, were brought to justice in the 2002 murder of newspaper publisher Domingos Sávio Brandão Lima. Reporters faced attacks and threats, and, in one case, had to flee the country temporarily, while others were arrested and targeted during anti-government protests that swept the country in the second half of the year. President Dilma Rousseff made international headlines after information leaked by former U.S. National Security Agency contractor Edward Snowden revealed that Brazilian electronic communications had been intercepted by the NSA. She responded by calling for a bill to regulate the country's Internet use in a way that would make it less vulnerable to spying, a move that, if implemented, could have widespread consequences for the global infrastructure of the Internet. Internet companies continued to receive numerous requests from Brazilian courts to remove content, as the media faced judicial censorship and hefty fines in defamation suits. After being initially silent on the issue, Brazil supported and defended the Inter-American Human Rights System from an attack led by a bloc of countries that sought to neutralize its work.
