The three were "murdered"? Is that a fact? You were there?
It is reasonable to assume, when prisoners are held without access to judicial review or observation by either humanitarian organizations or the press that they are tortured and murdered, agcatter. How could anyone be there? Such is not allowed by their captors.
And of course, even if they died by their own hands, this is irrelevant, as the causation was the brutal treatment meted out by their american captors. If they had been held in humane comfort, as a non-terrorist state, abiding by international law, would have done, they would probably not have killed themselves. Further, if they had been released after the State failed to charge them with anything, they would not have killed themselves.
If you like your empire, agcattor, and your fascist State, you should not mind when it murders. That is what it is for!
