You are right of course - there are far worse examples around. But as you say, a country that is supposedly setting the standard must live by the standards themselves - even be better than the standards they want to impose on others.I know you can find examples everywhere that might be a lot worse, but you'll have a hard time waving a freedom flag in people's faces when facts like that leak through.
Gitmo is hardly a standard that they would approve other countries of implementing.
