Yeah, I recently read a lengthy NY Times article on Florence ADX. How an unbelievable amount of inmates there are severely mentally unstable. Eating their own feces, chewing off fingers, attempting suicide, etc. Like pb and others here are saying, Florence was designed for the worst of the worst. That said, it's also a great addition to the feds arsenal of tools they can use to fuck with people who defy them, or stand up to them a bit too vigorously and flagrantly. Some people just can't bring themselves to be a good bitch, so as a 'fuck you', the feds shove Florence straight up your ass and let you rot for a couple decades. Only until the BOP gets the nod, will they decide to bounce you around until you're old and sick enough to die in Butner or Missouri.
