I gotta be totally freakin' honest with you. I think solitary confinement is about as useful as a chair with three legs. Put a prisoner in a windowless box for 20 years and ... wait, what?! Why? These places are worse than dog kennels. And I don't care what anyone says. Criminals are humans who deserve humane treatment. Period. The end. So done. Warning: A NSFW moment happens around 2:42.
