Wish I could say I was surprised by the complete lack of empathy a lot of people are showing here. In places where heat stroke is a serious risk in the summer (like a lot of the southern U.S.) it is simply dangerous to not have A/C in these facilities. Will they die? No, probably not, but prisoner or not they are still a Human being and should be treated with a shred of dignity. Not to mention that a content prison populace is oftentimes a more rule following prison populace.
Not everyone in prison is a hardened, remorseless killer. Many just want to serve their time and try to rebuild their life afterwards.
I have a family member who served a few years of prison time in Alabama. They didn't have A/C, but rather giant fans that only worked half the time and even when they did work they did a really shitty job of cooling the place down at all.
