Somos. is based on the ProPublica article "How the U.S. triggered a massacre in Mexico" by Pulitzer Prize-winning journalist Ginger Thompson.
About the title, creator James Schamus says: "We came to our work with two core objectives: to make visible the people our culture often works to erase from our perceptions and memories and to affirm our co-existence with them. In English, the phrase 'Somos' requires two words: "We are" or "We exist." But in Spanish, one word says it all. I asked if we could add a period after the title so that it reads as an assertion, and not just a title."
