Nope, parading POW's in front of cameras is forbidden by the Geneva Convention.
But brutally beheading captured American soldiers and vidiotaping the barbaric act for world distribution is quite OK? What the H--- do the Islamofacsists pigs care what Geneva Convention says? We all know that the most vile wicked thing you can do to a non-American prisoner is stick ladies' undies on their heads. No crueler act can be committed. You were being funny, right?
