Poppy had his filthy hands all over this...and it does parallel the goings on in New Orleans better than Kent State or Tienimen Square
Tlatelolco massacre
The massacre began at sunset when army and police forces — equipped with armored cars and tanks — surrounded the square and began firing live rounds into the crowd, hitting not only the protestors, but also other people who were present for reasons unrelated to the demonstration. Demonstrators and passersby alike, including children, were caught in the fire; soon, mounds of bodies lay on the ground. The killing continued through the night, with soldiers carrying out mopping-up operations on a house-to-house basis in the apartment buildings adjacent to the square. Witnesses to the event claim that the bodies were later removed in garbage trucks.
The official government explanation of the incident was that armed provocateurs among the demonstrators, stationed in buildings overlooking the crowd, had begun the firefight. Suddenly finding themselves sniper targets, the security forces had simply returned fire in self-defense.
