Much is being made of the revelations of the segment. I didn't see any.

Footage of CECOT is widely available as are interviews with former inmates. They allege effectively the same thing as what was claimed here by the accused TdA member. The Salvadoran administration is proud of CECOT and gleefully shows it off, including (as was shown in the segment) the solitary confinement cells.

There were no secrets revealed, nothing particularly new, and most importantly, nothing novel about the case of the accused TdA member. HN is acting like this segment revealed particularly damaging facts and therefore will be urgently scrubbed, but I'm not seeing anything new at all. I think the sentiment that the segment will be censored and we all have to run out and seed it is a bit hyperbolic. You can't try to hide CECOT's conditions when the people who run the prison happily give tours and show off what one might think they'd hide (punishment cells, for example).

There is no smoking gun, but more importantly there's nothing new in the segment that you can't already see in segments on Youtube. In fact, 60 Minutes used other people's footage of CECOT, not their own. Seed this all you want, but I don't think there's going to be a big push to make it go away. It reveals nothing that hasn't already been widely seen.
