Larry, the proof of what you say is in the comments you make.  And I've volunteered in more than one prison--at the request of Muslim community leaders--to lead Salaatul-Juma'ah (Friday worship-services) therein.  And I knew and worked with plenty of compassionate and caring COs in that context.  And then there are COs like Tamura, who misinterprets pretty much everything they see according to their own preconceptions and act accordingly.  Saw plenty of those, too.

I'm still in contact with one Shi'a brother I met back during those times (~1995-99).  He's out, married and working to support his family.
