Re: When did the concept of 'innocent until proven guilty' become 'guilty unless proven innocent'?
Well that happened at the latest when Gitmo was established and the US condoned waterboarding suspected terrorists for information.
Might have happened before that, though, the details are a bit hazy given that most of them are classified.
By the time those details are released, History will have been rewritten anyway, so the question becomes useless.
