For some reason this is not getting a lot of attention over here at the US. I can’t imagine why.
Chelsea Manning is apparently in the hospital following a suicide attempt. Solitary confinement is used as a torture technique in US prisons, and can be applied for the most trifling of reasons (“did you look at me?” “hey, look at me when I’m talking to you!”) or supposed gang membership. In some cases, like Manning, or Jose Padilla, it’s applied out of sheer nastiness.
