Man, I just read on the Colorado supermax prison El Chapo is most likely going to due to his breakouts. 23 hours solitary confinement (standard, not for misbehavior). Only visitation through the heavy plexiglass while restrained. The only physical constant he'll ever have with another person will be the few occasions the guards put cuffs on him.
Unabomber, Boston Bomber, Oklahoma city bombing accomplice Terry Nichols are all there. I tent to forget people like that are still alive in a hole somewhere.
