Abu Ghraib Prisoners

Daily Kos contrasts James Inhofe's and the ICRC's take on the Abu Ghraib prison population. This raises an issue I've wondered about: Who exactly are all these prisoners? We hear of a women's and children's section to the prison, but have yet to hear of women and children insurgents. I think months ago I read on Juan Cole that we were considering arresting friends and family members of suspected insurgents to use as hostages. Does anyone know if we went through with something like that?

This is a request for information, not a report of verified facts.

UPDATE: Dean Nation's Dana Blankenhorn wants a protest at Inhofe's Oklahoma office.
