Another point of debate on the role of pics and video feed of living pow's relating to the geneva convention, is that the Geneva convention ONLY applies to legitimate soldiers... if it can be shown that the brave US heros are fighting an illegal war (many countries are suggesting that this is precisely the case), then the brave american heros could legally be regarded as "illegal combatants"... and the Geneva convention will NOT apply in such a case, in which case al-jazeera did nothing wrong in showing video feed of our living pow's...
Another key point is that western media organizations have shown plenty of live video feeds of Iraqi pow's... so, on this basis, the US must ALSO condemn CNN, MSNBC, FOX etc, if America's use of the Geneva Convention argument is to have any credibility...
This whole area is open to legalistic debate on the international scene...
