It's nothing new. I would have linked to the archive photos of Abu Ghraib prison photos, but I'm not sure it's allowed, since they're NSFW. The fact that Bukele declared that no one can escape pretty much confirms that it's an actual death camp. There are metal bunks just like the ones in Auschwitz. The prisoners are kept inside for 23.5 hours, with half an hour of exercise in the lobby. The cells claim to have 1 sq. m. for each prisoner, with 80-100 prisoners, and there is no sunlight, only 24/7 artificial light. The prisoners don't speak(allegedly), and have no clocks or reading material. Some have lost their voice from not speaking. It's impossible to keep so many people in one place; some detainees must have died eventually to make space for the newcomers. Food is scant, and violence is common.
Funnily enough, I've seen a couple of articles refer to them as 'gulags'. They aren't fucking gulags. Spreading their propaganda even when they see something this horrifying. It would be funny if it wasn't nauseating.
