They cannot be allowed to even be seen or contact the outside world, not even family, because they can send messages to gang-world underlings on the outside to have anyone murdered or even to carry out mass murder. A whisper, a lip read, a gang-sign is all it takes. That is why they are never allowed outside of CECOT buildings. Never to meet with anyone from the outside. Never in public view. They are that dangerous. This is not a game.
