The reporting of the prison was suspect at best. They couldn't even give a definitive figure for its capacity, so maybe eight people have already escaped and they wouldn't know. The canteen looked quite roomy for a facility where prisoners have no contact with each other, as did the exercise area.
Far from being unique and geared towards the 'worst of the worst', one interviewee described it as almost identical to the cell he was placed in after running away from home as a child, in a completely different state. The cell and its facilities were more comfortable than police holding cells, which are often used for longer than overnight, and all were single rooms.
The report might have appealed to a certain audience, but had enough errors to be unreliable as documentary evidence. They weren't even sure El Chapo will be housed there.
