An interesting comment that was made a couple of days ago is that the BBC may have inadvertantly broken the Geneva Convention by showing the faces of Iraqi POWs as they were being passed back down the line, even though the point they were trying to make in the report is that they were being treated well and being fed and watered.
If you listen to some of Bush's comments he takes care to quite open language and not to use definitive statements about how the US treats prisoners of war. One news channel (Euronews I think) suggested that this may be on account of the criticism that has been made of the way Al Quaeda prisoners have been treated in Guantanamo Bay and the way in which the Geneva Convention has been interpreted there. (Note that I am relaying what others have discussed in news reports, I am NOT commenting on the rights or wrongs of the issue).
Gentlemen, the Geneva Convention applies to those States who are signatories.
That is correct, but secondary legislation framed in the ratification of the Geneva Convention will usually compell media organisations to adhere to the edicts of the act as part of any process of providing credentials. Some even go further in enshringing compliance in law.
