None of this very new, but a lot of the reporting is. America locks up an
astounding number of people; at any given point about half a percent of the US population is in jail, with a total of ~2.8% of the adult population being somewhere in the correctional system pipeline.
One simply cannot build a prison system capable of processing a percent of your population without the ability to either whole heartedly endorse, or at least ignore some pretty shocking abuses. A society that cared more about the rights and dignity of prisoners would not build such a system in the first place.
For comparison Canada currently imprisons 139 people per 100,000 residents, America currently imprisons 655. Germany is at 71, France is an 97, the Netherlands is at 63. America is literally incarcerating people at 4.7x the rate of its northern neighbor, and at 9-10X the rate for similarly rich EU countries.
But as a mildly funny anecdote to break the seriousness; Liechtenstein's prisoner stats have a funny detail -- Total prison population: 12.
