Because of the Color of My Skin and the Way I Speak Spanish:

While traveling on a bus to visit family friends in Tapachula, Chiapas in 2009, Tobyanne Ledesma Rivera, then in her early twenties, was singled out by migration authorities. The authorities boarded the bus but only asked two people, Ledesma Rivera and her mother, what they were doing there. According to Ledesma-Rivera, she and her mother were the only two visibly Afro-descendant passengers on the bus. In response, Ledesma Rivera and her mother explained their trip and each showed their voter identification cards, thus indicating their Mexican nationality. The migration authorities then demanded to see their passports; Ledesma Rivera responded that they had not brought their passports because they were traveling domestically in their own country. The authorities proceeded to take Ledesma Rivera and her mother off the bus and then separate them for interrogation.
