For posterity’s sake: a Spanish-language version of my previous post was recently published in Etilmercurio, under the title “¿Perdigones de goma nomás? Usando la física para caracterizar las municiones menos letales de Carabineros” (“Just rubber shot? Using physics to characterize the less-than-lethal ammunition of the Carabineros”). In addition to being in Spanish, the article contains an additional analysis using the Carabineros’ own spec sheet on their own rubber shot, which demonstrates the pellets are even more dangerous than what my own analysis would suggest.
Many thanks to Chris Harrod and Cristina Dorador, who facilitated the article’s publication, and the Etilmercurio team for their tremendous help with proofreading and publication.
