2001 Massacre of Plaza de Mayo

The 2001 Massacre of Plaza de Mayo was a massacre in the Plaza de Mayo in Buenos Aires and its surroundings. It occurred on December 20, 2001.
Five people (Carlos Almirón, Gustavo Ariel Benedetto, Diego Lamagna, Alberto Márquez and Gastón Marcelo Riva) were killed there, four others were attempted to be murdered (Marcelo Dorado, Martín Galli, Sergio Rubén Sanchéz and Paula Simonetti). Others were injured. 
The events occurred under the presidency of Fernando de la Rúa during the December 2001 crisis in Argentina, during which 39 people were killed, including seven children between the ages of thirteen and eighteen.
Criticism.
The journalist Alberto Amato of the newsroom of the newspaper Clarín, a month after the massacre, referred to it with these words:
“The massacre of the Plaza de Mayo... bloodied the city with a violence and unreason that recognizes as the only precedent the terrible bombardment by naval aviation in June 1955, three months before the overthrow of Juan Perón... Among other responses that the judicial investigation include those that try to know if there was a moment, and therefore an order, that the repression of the protesters was carried out with bullets. And who gave that order. Who were the civilians who shot at the protesters protected by uniformed police?  Who owns the cars from which people were shot at close range and that a police chief defined with a euphemism that would be nice if it did not contain a tragedy: "civilian cars for police use..."? How was it that, if the decision of the then government was to prevent a hypothetical "takeover" of the Government House, the dead fell several blocks from the seat of power? Did some kind of “death squad” act on December 20? If Justice manages to answer these and other questions, it will elucidate another that is only tacitly formulated: what is the political will to investigate a massacre almost without precedent in the already violent contemporary history of Argentina.” 
Trial.
