Only two US prisons were on it.
I think you need to work on your counting skills. I counted 4 current US prisons and one closed (Alcatraz) out of a total of 20.
25% is extremely bad given the US's self perceived high ground in all things moral. Remember this includes the entire world, most of which is comparatively very poor and lacks the resources to do much better.
That said, imgur is hardly a reputable source and the list has clearly been skewed by US prison's notoriety in the west. I'm sure there are far worse out there.
No prison thinks much of human dignity.

Only fools support prisons that ignore the dignity of the prisoners. If you actually want to help society, you support and protect those that need it the most.
No one has the slightest idea what the icons are.
It would take quite the academic to not know what binoculars are. Seriously, almost everything in the world is a throwback/reference to something that nobody uses/knows what it is any more. Compared to the English language, these icons are stupidly up to date. Fact is, they become self referencing and everyone knows what they mean. I don't want a big long box that says Address book when I can click on an easily recognisable icon. Stop fucking about with a system that works perfectly because of some flawed ideology.
