On Sep. 26, 2014, in the town of Iguala, in the state of Guerrero, Mexico, 43 students from the Ayotzinapa Rural Teachers' College  got on a bus and were never seen again. The Mexican government says corrupt police handed them over to a drug cartel, which murdered them and set their bodies on fire, but independent investigators — and the families of the disappeared — say the government's version of events does not add up.

IN DEPTH: Justice for Ayotzinapa

The story has spread beyond just Mexico. An exhibit that just opened in Los Angeles, California, "Ayotzinapa: A Roar of Silence," features the work of 43 artists from around the world who, through their art, are seeking to call out the incompetence and complicity of the Mexican government. Artist and activist Francisco Toledo, working with the Oaxaca Institute of Graphic Art, organized the exhibit, choosing from over 700 designs submitted by artists from China to Iran.

Thanks to the Center for the Study of Political Graphics for providing the artwork.
