Wasn't it actually the US that failed to fulfill the terms of that agreement?

But what's that got to do with this thread anyway? We seem to be wandering all over the place (and I've done my share of wandering, I admit it).

Here is a link about the legal position as regard torture, and how it's defined and so forth, whcih seems relevant enough - COMPILATION UNDER INTERNATIONAL LAW - DEFINITION OF TORTURE

Since USA seems to be backed out of most agreements on international law, it'd be interesting to know what the legal situation is under your constitution when it comnes to torture, more especially when it comes to non-citizens.
