I believe that the inhumane treatment that went on in UK/NI was not systemic but a result of individuals acting of their own accord. Guantanamo Bay was chosen to locate the camp in order to allow these kinds of things to go on because American law does not apply there.
I do think a lot of the Northern Ireland stuff was institutional. Gerry-mandering of election results, police oppression, etc.
The point was that whilst nowhere is perfectly just and or free, there is the perception that the USA promotes itself as being so.
