Declassified files on migrant massacres reveal impunity and Mexican state complicity in human rights atrocities that predate the recent Ayotzinapa disappearances.
Central American migrants are the most vulnerable of the vulnerable. Their resources are few and once they leave home they have no legal rights. Crossing Mexico, they are routinely held captive and extorted, not only by criminal gangs, but by unscrupulous public officials, private guards, transporters and even their own guides as they make their way northward. Sometimes, they simply disappear—not infrequently into enforced prostitution or perhaps into common graves.
