I didn’t get to make small talk with these two to ask, or was too afraid to do so, but they have all the earmarks of being members or former members of Mara Salvatrucha aka MS-13, a criminal gang originating in Los Angeles and made up predominantly of Salvadorans. During one of the 400 pueblos naked protests on Eje Central, the main drag dividing Mexico City’s Historic Centre, this pair arrived on the scene to add to the spectacle, happily posing for photos for the shocked and curious.
