NPR: Mexico's 1968 Massacre: What Really Happened?

"In the summer of 1968, students in Mexico began to challenge the country’s authoritarian government. But the movement was short-lived, lasting less than three months. It ended October 2, 1968, ten days before the opening of the Olympics in Mexico City, when military troops opened fire on a peaceful student demonstration. The shooting lasted over two hours.
The Massacre of Tlatelolco has become a defining moment in Mexican history, but for forty years the truth of that day has remained hidden.
