The concentration of media ownership in very few hands and a high level of impunity undermine the freedom to inform and encourage self-censorship. Journalists who dare to tackle sensitive subjects such as corruption and drug trafficking are exposed to the possibility of threats and violent reprisals, or even murder by government officials or crime cartels. Elected politicians often abuse their position to stigmatize critical journalists. The repeal in 2016 of legislation under which journalists could be imprisoned for defamation was a major step forward for the media and democracy.
