I was thinking more generally, about the fact that these sites are set up and used specifically to avoid due process. I mean by definition, the people being tortured, not having been found guilty of any crime, are innocent.
Why I should use "unconvicted", which implies possible guilt, for people who have not even been charged with anything, but are simply imprisoned and/or tortured indefinitely?
That's not what innocent means. You should use unconvicted.
