Using guns, grenades, explosives, and other deadly means, criminals have assaulted four Mexican newsrooms in less than six weeks.

Press fatalities in Mexico remain among the highest in the world, leading to vast self-censorship. And the perpetrators? They are not only well organized and heavily armed, they enjoy near-complete impunity for their attacks on the press. Mexican lawmakers began to address the crisis this year, but now they risk losing the momentum.
