I used to visit the Florence ADX facility regularly for business. There are many things I do not know about the facility, but there are a few things I do know. Firstly, all inmates are put into their own individual cells - one per person. They are all locked down in these cells for 23 hours a day (toilets and lavatories are in the cell, and meals are brought to them). They are released from their cell for one hour in every 24 (in cuffs and chains) so they may either visit a rec area outside of the building, or to take a shower and clean up. At no time are they in contact with another prisoner.
Abdulmutallab has nothing more than any other inmate, nor does he have any less than others at the facility from what I've read here. I think he's tired of prison and just wants to cause trouble. Other inmates have tried similar things at Florence and failed.
Finally, IMO, it's too bad that people who aren't even citizens are able to try and use our criminal justice system against us.
