So when a terrorist is corresponding with somebody else who's not known to us but is engaged in doing or supporting terrorist activity, or someone who's violating international sanctions by providing nuclear weapons-related material to a country like Iran or North Korea, is trying to hide that activity because it's illicit activity.
Por eso cuando un terrorista escribe a alguien que no conocemos pero realiza o apoya actividades terroristas, o alguien que viola sanciones internacionales proporcionando material para armas nucleares a un país como Irán o Corea del Norte, trata de ocultar esa actividad porque es ilícita.
