Contribution: how do you call the action of a police officer writing down a ticket for your traffic infringement ? We call it "hacer la boleta".
Well, this was the expression that the military used in Argentina in the 70s, meaning assasination in the dark, or disappearance. 30,000 "boletas" were written down, but the world did not notice. Nobody came to liberate us, perhaps because those killed were considered a "threat over democracy", and the military regime was not very dangerous to other countries... until they decided to put a hand on the Falkland Islands (Malvinas). Fortunately the regime fell down by its own corruption and by pressure of the people. A case of "non-viability".

Un abrazo,
