This is the second tour video I've watched. According to some of the commentary in the videos, this is where all the accused of gang-related crimes in El Salvador are sent and the prison can house a total of 40,000 inmates at a time.
The first video I watched didn't show the solitary cells, so I was surprised people serving life sentences in these conditions were so tranquil, but this video showed the solitary cell which lacks even light.
I don't have a judgement to share, but it's helpful to see how the gang solution is shaping up.
