Ronna Rizquez a Venezuelan journalist has covered Tren De Agua for years and wrote the definitive book on the gang. She says the gang doesn't actually have an identifying tattoo, no Venezuelan gangs really do.
She said the trump administration literally made up the tattoos as an excuse. for example from pics she's seen, a couple of them have a watch tattoo which is actually an homage to Messi the soccer player, a couple more have an homage to Puerto Rican singer Anuel AA who passed away. She said none of the pics of "gang tattoos" ICE is showing are actually gang tattoos at all, just totally made up excuse.
